Introduction

The use of various devices with WiFi is rapidly breaking into our lives, now WiFi is equipped not only with complex equipment like laptops and communicators, but even such simple gadgets as a photo frame. Configuring them to connect to wireless networks is becoming a daunting task, so it's no surprise that technologies have emerged that make it much easier to set up.

Creating a new wireless network begins directly with the configuration of the access point (wireless router) connecting computers and other wireless equipment to it.

Technology

From the point of view of an ordinary user, the traditional setup method looks very complicated: you need to perform difficult actions with connecting to an access point for the first setup, you need to manually create a wireless network name, specify a complex and hard-to-reproduce security key. And this whole setup process requires the user to have a basic knowledge of WiFi. It will be much easier for him to just press a button or enter a PIN so that everything is set up and connected by itself.
Wireless Protected Setup (WiFi Protected Setup - WPS) was just invented to quickly, as simply and safely as possible configure network devices and computers. For example, one way to connect a game console with WiFi to a wireless network is to simply press the WPS buttons on the wireless router and on the game console.

WiFi Protected Setup is now the standard for easy and secure wireless networking. In Microsoft terminology, this Windows Connect Now (WCN).

The configuration environment for wireless devices can vary: ethernet, WiFi,USB cable or USB flash drive. The wireless device can be configured via Pin (PIN - Personal Identification Number), by pressing the configuration buttons (PBC - Push Button Configuration, Push Button for short) or via import network settings.

Setting up your wireless router

The device is unpacked and connected to the mains. You can configure it via Ethernet using a patch cord (which is included in the package) or via WiFi, but the configuration process itself does not depend on this. On a laptop or desktop, you need to go to Control Panel - - Set up a new connection or network where to choose Creating and configuring a new network.

WCN-enabled wireless devices will be visible in the device list. We select exactly our access point (wireless router) (not the neighbor's if we are configuring via WiFi).

The next step is to enter the PIN code from the label on the router.

Or set your own, there is a need for this: the name of the wireless network, the password for accessing the network, the security level and the type of encryption.

Upon completion of the setup, you can print detailed instructions for connecting other computers to the access point (wireless router), as well as prepare a USB flash drive with settings for importing a network profile to other wireless devices. If at the moment this is not necessary, then this can be done later, in the properties of the wireless network.

Connecting to an access point via Push Button

When connecting to our wireless network from a computer running Windows 7, you can not enter the security key, but press the WCN button on the router. The connection to the wireless network will happen automatically.

On wireless devices that support the PBC method, just press the WPS button on the router, and then on the wireless device, after which the device will connect to the wireless network.

On computers running older Windows operating systems, and on wireless devices that do not support the Push Button method, you must use Import Wireless Network Connection Profile.

Connecting to an Access Point by Importing a Network Connection Profile

If the USB flash drive with the network profile settings was not created upon completion of the access point (wireless router) setup, then you need to create it. To do this, you need to connect a USB flash drive, in connection center call properties wireless network and select Copy this network profile to a USB flash drive. You can also open properties wireless network through Control Panel- Network and Sharing Center - Wireless Network Management.

After completing the wizard, the USB flash drive can be used to connect various wireless devices, as well as computers equipped with a wireless adapter and running Windows XP/Vista/Windows 7.

For devices with a wireless adapter, such as photo frames, printers, game consoles, you need to connect a USB flash drive with a network profile to them and agree to import the settings. After the setup is complete, the device will automatically connect to the wireless network. Similar actions for Windows operating systems: connect a USB flash drive with a network profile,

in the window Autostart choose Connecting to a wireless network using Windows Connect Now,

agree to import settings.

If the autorun function is disabled on a Windows computer, you need to open a USB flash drive, run the file SetupSNK.Exe and agree to import settings for connecting to a wireless network.

Windows Connect Now makes setting up your wireless network much easier, so you don't have to remember your network credentials and spend a lot of time connecting new PCs.

Often, Windows users encounter a problem when there is no wireless connection in the network connections of the laptop, and a “cross” appears on the connection status icon in the tray.

At the same time, the WiFi access point functions properly and distributes the Internet to other gadgets and devices.

Hovering the mouse over such an icon will display a "no connections available" alert. The situation is unpleasant, but do not rush to carry the PC to the service center.

After all, even if there is no Wi-Fi icon in the launched window of the Network Control Center, it is possible that the PC hardware is fully operational and does not need to be repaired.

In most cases, a similar problem can be diagnosed and solved independently. To do this, you just need to know the reasons for its occurrence and how to correctly configure the wireless connection.

A short list of possible sources of the problem and their solutions

Among the most common reasons for which there is no wireless network connection in the computer, the following can be distinguished:

Often in laptop models, the Fn buttons and one of the function keys, for example, F2, are provided for this. A bona fide manufacturer always puts an appropriate pattern on the desired button, symbolizing wireless communication.

Sometimes a separate switch with this pattern is placed on the ends of the laptop:

1. Infection with malware. The actions in this case are obvious, you should make a complete analysis of the PC for the presence of viruses and, if detected, remove them;
2. It often happens that the network is unavailable due to the blocking of some functions by the antivirus utility or firewall. It is recommended to temporarily try to deactivate them.

How to make sure you have a Wi-Fi adapter?

In the absence of this module, there is also no Wi-Fi icon in the tray. And if it is, but a message is displayed that there is no connection, then the device model is usually indicated by the manufacturer on a sticker that can be found on the laptop case.

The owner of a stationary PC can accurately verify the presence of a wireless receiver simply by inspecting the system unit. When an external antenna is detected, it can be concluded that it most likely belongs to the WiFi adapter.

It is very easy to determine the adapter model using the Windows tools. To this end, it is necessary to carry out only a few sequential actions:

Software

Windows provides for automatic loading of drivers, however, it happens that the software of some devices is not installed or does not work correctly.

In such cases, you need to install the software yourself. To do this, you need to take just a few steps:

If the above did not lead to a successful result, then you will need to perform the following steps:

1. Re-enter the "Actions" tab;
2. Click on the line "Install an old device";
3. In the window that appears, click "Next";
4. Specify "Automatic search" or "Manual";
5. Then select "Network adapters";
6. Find the device model in the list;
7. Wait for the installation to complete and restart the PC.

If you need to update the drivers, then the algorithm will consist of the following steps:

1. Guided by points 1 - 5 from the first instruction, launch the "Device Manager";
2. Then, from the problematic equipment, call the context menu;
3. Click "Update driver";
4. It is recommended to specify "Automatic search", and the OS will find and install the software on its own;
5. Or, if the user has downloaded the software in advance and saved it to the PC, click "Search on the computer" and show the location of the downloaded drivers.

To manually find and download the appropriate software, follow these steps:

1. Open device developer resource;
2. In the search field, type the model of the equipment and click "Enter";
3. Enter the "Devices" section;
4. Save device drivers to PC memory.

If you encounter difficulties with the manual execution of the task, you can use programs that are specially designed for installing software. One such application is "Driver Booster".

The advantage of using it mainly lies in the automatic detection of the device model and loading the latest software modifications.

Network configuration

In order for the laptop to correctly connect to Wi-Fi, you need to run diagnostics.

Diagnostics:

Is there no Wi-Fi icon in the Windows taskbar or in the Network and Control Center menu? This does not mean that the equipment is out of order. Equipment failure is only one of the possible causes. In some cases, you can do it yourself.

What to do if there is no "Wireless Network Connection" icon.

This problem appears if:

Is there a Wi-Fi receiver?

If the receiver is not installed on the computer, then you will not see the Wi-Fi network icon. But how to check what kind of adapter you have? The simplest thing is to look at the characteristics of the PC. Laptops should have a sticker that lists the specifications of the device. Another option is to find out the adapter model and find information about it. Do you have a desktop computer? Then find the ports on the system unit for connecting the modem. If an antenna is installed there, then the product is suitable for working via Wi-Fi.

And the easiest way:

1. You need the Windows Control Panel.
2. Open "Device Manager". It's in the Hardware and Sound category.
3. Expand the "Network adapters" menu.
4. See if there are any models that say "Wirelles", "802.11" or "WiFi".

If there are no such inscriptions, you will not be able to set up a wireless connection. But you can purchase a Wi-Fi module or a network card that already has an antenna. There are also external Wi-Fi receivers.

Driver

Windows usually loads the software it needs on its own. But if the network hardware driver is missing or corrupted, it must be installed manually.

To connect, you need to download the software. There are several ways. The first is suitable if the driver was installed incorrectly.

1. In the Dispatcher, right-click on the item with the yellow triangle.
2. Select "Delete" and confirm the action.
3. Restart your computer.
4. After starting Windows will "detect" the presence of a new device.
5. If this does not happen, go to the Manager again.
6. Highlight any item.
7. "Actions - Update Configuration".

This will only work with equipment that is installed on a Plug and Play basis. The software for these devices boots automatically. You can use them immediately after connection. If the board, in general, does not have such a function:

1. Highlight any item in the Dispatcher.
2. "Actions - Install old device"
3. An explanation window will open. Click next.
4. Check "Automatic search" or "Manual".
5. Select "Network adapters".
6. If you know the model and type of gadget, find it in the list.
7. Wait for the installation to finish.

To download an update for outdated software:

1. In the Manager, right-click on the device.
2. In the drop-down list, click on "Update driver". This option will be active if Windows has determined the hardware model.
3. Select "Automatic search" so that the system finds the software on the network and downloads it.
4. Or click "Search on computer" to specify the path to the installer.

A disc should come with a new Wi-Fi adapter or laptop. You can download the necessary software from it. If you don't have a driver CD and the system didn't find it on its own:

1. Go to the network equipment manufacturer's website.
2. Copy the model name into the search bar.
3. Open the page with information about your adapter.
4. Download software from there. It's usually located under Support, Downloads, Files, or Programs.

There are special applications for installing system software. For example, Driver Booster. It determines the hardware model and downloads the latest driver versions for it.

Settings

You may have the wrong network configuration. To connect to Wi-Fi, you need to configure it. Run diagnostics first.

To connect to an access point, the Wi-FI module must be active. On laptops, it can be controlled using a keyboard shortcut. Which buttons to press depends on the gadget model. For example, "Fn + F5", "Fn + F7" or "Fn + F9". They have corresponding pictures. But sometimes users touch them by accident. Yes, and on a stationary computer, the Wi-Fi module can be disabled. For settings:

Now you can reconnect "over the air" if the Wi-Fi icon disappears. But if the network card is still broken, it is better to contact the master at the service center.

Imagine being able to surf the Internet while sitting on the couch in your room, chatting with friends online from the comfort of your cozy bed at night, or sending documents from your kitchen computer to your home office printer. The wireless network has the greatest possible flexibility and does not require complex configuration. This article describes the steps to set up and start a wireless network.

The right choice of equipment

Before you begin setting up your wireless network, you will need the following items.

A broadband Internet connection is a high-speed connection, unlike a dial-up connection, which has a low data rate and is not powerful enough for a wireless network to work. The most common broadband connection methods are DSL lines and cable. To get a broadband connection, you need to contact your Internet Service Provider. DSL Internet connections are usually provided by telephone companies, while cable connections are available from cable companies. Internet Service Providers usually provide high speed modems and may even connect them to your computer. Some vendors may even offer a bundle - a modem and wireless routers. This equipment can also be found in stores that sell computers and electronics.

Example of cable modem (left) and DSL modem (right)

Wireless router

The router provides data exchange between the local network and the Internet. With a wireless router, instead of wires and cables, computers are connected to the local network using radio signals. There are several different types of wireless network technologies, including 802.11a, 802.11b, 802.11g, and 802.11n. It is recommended to use routers that support 802.11g or 802.11n as these routers provide high bandwidth and strong radio signal. For more information about wireless LAN technologies, see Wireless Networking FAQ .

Wireless Router Example

Wireless network adapters

A network adapter is a device that connects a computer to a local network. To connect a laptop or desktop computer to a wireless LAN, you need a wireless network adapter. Many laptops and desktop computers have built-in wireless network adapters. To check if a wireless network adapter is installed on your computer, follow these steps:

Device Manager showing wireless network adapter

If your computer does not have a wireless network adapter installed, you can buy one from a computer or electronics store and install it yourself. We recommend using Universal Serial Bus (USB) based adapters. These adapters are small, easy to install and transfer from one computer to another. Make sure the adapters are the same type as the wireless router. The type of adapter is usually listed on the packaging - usually a letter, such as G or A .

Examples of USB Wireless Network Adapters

Installing a modem and setting up an Internet connection

After all the equipment has been purchased, you will need to install a modem and set up an Internet connection. If the modem was not installed by an ISP representative, follow the instructions in the modem's documentation to connect the modem to your computer and the Internet. If using a DSL line, connect the modem to the telephone jack. If using a cable, connect the modem to a cable outlet. For more information, see Set up a high-speed cable or DSL connection .

Placement of the wireless router

Install your wireless router in a location where it will receive the strongest signal with the least amount of interference. For best results, follow the tips below.

Locate your wireless router in the center of your service area. Install the router as close to the center of the house as possible to provide the best possible radio signal in all areas of the house.

Place the wireless router higher off the floor and away from walls and metal objects such as metal cabinets. The fewer physical obstacles between the computer and the router, the more likely it is that the router's signal strength will be fully utilized.

Reduce interference. 802.11g network equipment uses 2.4 GHz radio frequencies. This frequency is also used by many microwave ovens and cordless phones. When you turn on the microwave oven and make a cordless phone call, the radio signal may be affected by interference. Many problems can be avoided by using a cordless phone that operates at a higher frequency, such as 5.8 GHz.

Wireless Security

Security is always important, but especially in the case of a wireless network, as the network signal can reach outside the building. If you do not secure the network, then people nearby who have a computer can access information stored on network computers and access the Internet through your connection. To secure your local network, follow these steps:

Create a network security key

Write down the security key and keep it in a safe place. You can also save the security key to a USB flash drive by following the wizard.

Use a firewall. A firewall is software or hardware that helps protect your computer from intruders or malware. Using a firewall on each computer on the local network allows you to control the spread of malware over the network, as well as protect computers when accessing the Internet. Windows Firewall is included with this version of Windows. See Firewall FAQ for more information.

Adding computers to the network

To connect a laptop or desktop computer to a wireless network, follow these steps:

Sharing files and printers

Many users have wireless networks that allow them to access the Internet from any room in the house, but would like wireless access to files and printers.

The easiest way to share files online is to set up sharing with a homegroup. If there is no homegroup, you can share files by placing them in one of the shared folders. Any file or folder placed in a shared folder is automatically made available to other users connected to the local network. To share a shared folder, follow these steps:

Open the "Advanced Sharing Options" section. To do this, click the Start button and select Control Panel. Enter network in the search box, select Network and Sharing Center, and then in the Navigation Pane, click Change advanced sharing options.

Click the double quote icon to expand the current network profile.

In chapter Access to shared folders select one of the following options.

• Enable sharing so that network users can read and write files in shared folders.

  Turn off sharing (Users who are signed in to this computer will have access to shared folders).

This article will help answer the following questions: how to set up hotspot, how to set up a router and bring clarity. According to the manufacturers of wi-fi equipment, setting up a wireless network (WLAN - Wireless Local Area Network) is a matter of minutes. The button is pressed and the device is connecting. In reality, wi-fi routers are confusing even for experienced PC users. Most are happy with the fact that there is a signal at all - reliability is usually forgotten. In this article, you will learn how to set up a Wi-Fi hotspot, how to set up a Wi-Fi router, and how to make a reliable wireless connection to protect your network from unwanted guests.

I want to say right away that new detailed material has appeared on setting up the router:. I recommend using it first of all to set up a wi-fi router.

Which Wi-Fi router or access point to choose

Choosing a Wi-Fi router. The stumbling block for multimedia transmission is always the Wi-Fi standard. You can quickly transfer large files or watch HD video wirelessly only if it complies with the 802.11n standard, which supports speeds up to 300 Mbps. I also advise you to read about the new wireless network standard - in order to buy a device with a reserve for the future. If this is not necessary, then choose any router from a well-known manufacturer ( D-Link, TP-Link, Asus or Netgear) that comply with the 802.11n standard - this is more than enough for any high-speed Internet connection.

WiFi adapters. Users who use modern laptops or PCs with an integrated wireless network adapter do not need additional equipment, and owners of older laptops need to take care of Wi-Fi modules on the USB bus or Wi-Fi Card-Bus adapters.

How to locate a Wi-Fi hotspot or Wi-Fi router

All three Wi-Fi networking standards typically operate at 2.4 GHz. As a result, several problems arise. One of them boils down to the fact that not only Wi-Fi equipment works in this frequency range. For example, microwave ovens, cordless phones, and wireless extenders also use this frequency, which increases the level of interference. Another problem is related to the environment of the signal passage: the human body, reinforced concrete structures degrade the quality of the signal if they are located along its route. In order for the signal to be available throughout the entire room, it is important to choose the right place. The connection works best if the router is mounted on the wall as high as possible. In addition, the router should not be located directly behind a computer or other device that has strong radiation or interferes with radio waves due to the metal case. The correct location of the antennas of the router is also critical. In most cases, you can get more coverage by pointing them vertically.

Connecting and configuring a Wi-Fi router (access point) for a local (internal) network

Connect the computer and the router with a network cable (usually use sockets for an external network, there are usually 3-5 of them, they are located nearby and signed. Make sure that your computer is connected to your wi-fi router (the connection icon in the taskbar tray lights up) .

• IP address: 192.168.0.2
• Subnet mask: 255.255.255.0
• Default Gateway: 192.168.0.1
• DNS: 192.168.0.1

If you found other options in the manual, set them. Open a command prompt ( Start - Run- in the window that opens, write "cmd" for Windows XP or click Start and type "cmd" in the search bar). Next, in the command line that opens, write: ping 192.168.0.1 . If packets come from 192.168.0.1, then you did everything right. If there is no answer and we see messages about exceeding the waiting limit, it is worth trying to change the IP 192.168.0.1 and 192.168.0.2 to 192.168.1.1 and 192.168.1.2 respectively, and then try to “ping” the address - 192.168.1.1 If you still fail, then refer to the manual to understand what IP address the router accepts on the internal interface.

I also recommend that you check once again whether the network cable on the router is plugged into the socket, whether a crossover cable is used. AT wifi router connection guide it should be written how to get into the web interface to manage the router, if you can’t find this section or the manual itself is missing, you should check the addresses http://192.168.1.1 or 192.168.0.1 , depending on which address we managed to ping. in your computer's browser. If you have already tried to connect it to the router, then you must first reset the settings with the button "Reset" on the back. It is also worth checking the same addresses but with a secure protocol https://, instead of http://

On the page that opens, you will be asked to enter your login and password, if nothing is indicated in the instructions for connecting the wi-fi router, then you should try the admin / admin or admin / password pair - these are the most common pairs and they are found in almost all popular router models. After entering the administration mode, select the Russian language in the interface settings section so that everything becomes intuitive, if it is present.

Most often, Wi-Fi routers allow packet forwarding on the intranet interface, so you can already turn on additional PCs and connect them through other internal network sockets and start using the internal network.

How to set up a Wi-Fi router

How to enter data to access the Internet connection, we will consider below, using the example of one of the Wi-Fi routers, but for now let's go to the settings section "Wireless Settings" ( wireless network setup) or to the section “Wi Fi”, “Wireless”, etc.

Now give the name of your home Wi-Fi network in "Name (SSID)". Under this name, the wireless network will be displayed in the list of available networks on the other device. Select your region (Europe - the American installation has a long range, which, however, is prohibited in our country). In the "Channel" column, set the value to "Auto" - then the Wi-Fi router will analyze the air and will use the channel with the least amount of interference. Confirm the settings by clicking "Apply".

Wireless security

The network is installed, now it's up to the choice of protection. Without a strong password, anyone can access the Internet through your connection. There are three main encryption methods in protecting a wi-fi network: WEP, WPA and WPA2. All of them are vulnerable in one way or another, but with my help, your network will be quite reliably protected from hackers. Encryption using WEP is extremely insecure - we recommend that you do not use it. WPA (Wi-Fi Protected Access) encryption, which is based on the AES encryption method, is fairly secure and difficult to crack. To select keys, a hacker will need many years or a computer that is orders of magnitude faster than current PCs.

Better security is offered by WPA2. True, hackers were able to find a loophole here too, but the costs of hacking are too high. However, all these protection methods require a dedicated authorization server (RADIUS), which is not applicable in a home network or a small office network. They are encrypted using WPA and WPA2 with predefined keys. To use them, on the "Wireless Settings" tab, activate "WPA-PSK (TKIP)" or "WPA2-PSK (AES)". When prompted for "Security Encryption", set a password - it is not recommended to use less than 15 characters for it. Confirm the entry by clicking on "Apply".

Optional Wi-Fi router setup

Each device on the network has its own MAC (Media Access Control) network address. In the router, you should register the addresses of only devices you know - others should not have access to the router. To do this, click on the "Advanced" menu item on the "Wireless Settings" tab and select "Setup Access List". After that, you will get a list of connected devices. It is easy to find out the MAC address of a wifi module on a laptop or a wifi network card on a PC - in the command line, type “ ipconfig /all” Select the computers for which you want to open access, and click on "Add" (Add). Now check the box next to "Turn Access Control On", click no "Apply" - and the hacker-proof network is ready. Do not forget that all this is best done after you set up a wireless connection on client computers.

Restart the Wi-Fi router through the web interface and try to set up a network on your device using the following settings:

IP– from the range of free addresses
Mask – 255.255.255.0
getway – 192.168.(0-1).1

Setting up the Internet on a Wi-Fi router or setting up an external network

If we need to wire the Internet over the internal network, we need to connect the network cable with the “Internet” to the external interface on the wi-fi router (the external interface is usually located a little away from the others and is signed accordingly WAN)
After that, in the router settings, you need to specify the settings for the external interface of your provider: usually they are in the contract, or call technical support. You should also not forget about DNS - the router probably has a caching DNS server or, in extreme cases, a DNS tunnel, configure it. It is also worth checking whether the exchange of packets between interfaces is allowed, if so, then the Internet most likely already exists in your internal network.

By the way, I want to note that the latest models of wi-fi routers and some of the previous ones (Asus, for example) have the ability to work with the PPPoE protocol - which has recently become more and more common among providers, so at the end of the article you will find a step-by-step instructions for setting up a wi-fi router with a connection via the PPPoE protocol . If your Internet is exactly like this, then make sure that you have a router with PPPoE support. On I have described the main types of Internet connections so that you can determine yours.

Gh34EwF-MB4

P.S. Let me remind you once again about the “cherished button” that answers the question “ How to reset the password on the router, if I forgot the old one. Each router has a “Reset” button - after pressing it while the router is running, it reboots and all settings are set to the original ones.

Setting up a wi-fi router. Troubleshooting a Wi-Fi network

Why doesn't Wi-Fi want to transfer data? You are connecting to Wi-Fi, but the browser cannot display the site. Let's find ways to solve this WLAN problem:

Weak signal Wi-Fi connection. Sometimes a WLAN transmits data one and a half, two times slower and the signal is always bad, regardless of the location of the antenna. Cause: Your network is being covered by another WLAN that operates on the same frequency. In order for several radio networks to exist side by side without overlapping each other, the 802.11b / g standard provides 13 channels at a frequency of 2.4 GHz. Many routers are set to channels eleven or six. With free app NetStumbler you can find and recognize neighboring WLANs and find out which channels they operate on. Download the app from the official website and start searching. After that, you will see the channels of the networks around you. Now, through the web configuration of the router, set your WLAN to one of the channels that is not used on this network and check if the signal has improved.

How to increase the range of a Wi-Fi network. If the range of the Wi-Fi router is insufficient, WDS technology (Wireless Distribution System - distributed wireless system) is usually used. It allows Wi-Fi access points to establish a connection not only with clients, but also with each other. Each of them receives a signal from the other and transmits it further. However, this increase in range translates into the cost of another set of access point equipment. The next drawback: the access point must provide simultaneous connection to both the network and the client - this reduces the efficiency by half. directed.

The Wi-Fi router or Wi-Fi hotspot is losing connection. The network is functioning normally, but the connection is constantly broken. The problem is most likely the poor quality of the power supply. Even a small voltage drop is enough for the router to lose connection. Solution: Get a small uninterruptible power supply and connect the router through it. If this happens infrequently, most users turn off / on the device, but this is not an option.

Disconnected wi-fi connection. When the wi-fi router and computer adapter are made by different manufacturers, it may cause some problems. As a rule, updating the software helps here. Find the latest version on the vendor's website and install it through the configuration menu. Especially often this problem is solved by updating the firmware on D-Link access points and routers.

Common mistakes and setting up a Wi-Fi router

Wrong IP configuration. In order for two network communication components to share files, each needs its own IP address. This network data is distributed by the DHCP (Dynamic Host Configuration Protocol) server in the router (do not forget to check in the router's web interface that the DHCP server is enabled). Open Control Panel and select Internet Connection. Select "Settings" from the WLAN connection menu. Next, double-click on "Internet Protocol" (TCP/IP) and activate the "Obtain an IP address automatically" option. Confirm by double-clicking on "OK". If you have several devices that can be DHCP servers, there may be a conflict between them. This leads to real chaos. Use the DHCP Find app to track down which device is causing the problem. It reports the MAC addresses of the DHCP server. MAC addresses are usually written on the underside of devices. In this way, you can quickly identify the troublemaker and disable the DHCP server in it. If the connection is still not functioning, the proxy server settings in the browser may be to blame. Set up your browser: In Internet Explorer, click on "Tools | Internet Options" and go to "Connections". In the "LAN Settings" section, uncheck all items, including "Auto-detect settings". Other browsers such as Firefox, Chrome, or Opera have similar names for these features.

Go to the Internet Explorer, Mozilla, Opera, Safari browser and type 192.168.0.1 in the address bar. In the window that appears, in the "Username" field, enter admin, in the "Password" field, enter password and click the "OK" button.
After this procedure, the router menu will appear:

Setting up a PPPoE connection
Click the "OK" button in fig. above. "Basic settings" will appear (in the menu on the left it is: Installation - Basic settings).
To the question "Do I need to enter connection information when connecting to the Internet?" answer "Yes":

In the "Internet Service Provider" select "Other" (which corresponds to the type of connection PPPoE):

Connection mode - connection establishment mode. "Always on" for a permanent connection. “Connect on demand” - establishes a connection when necessary - that is, when there is traffic directed to the Internet, the device will establish a connection, and if there is no activity for more than the time specified in “Idle time before disconnecting (in minutes)”, it will disconnect. If "Manual connection" is selected, the connection is established and terminated manually

"IP address on the Internet" leave "Obtain dynamically from an Internet service provider" , if the IP is not given to you by the provider (static) , like the rest of the parameters (everything should be in the contract):

DNS server addresses can be specified manually, if there are any from the provider, or leave the receipt automatically:
Master DNS: xxx.xxx.xx.x
Secondary DNS: xxx.xxx.xx.x

"MAC address of the router" is left by default:

Setting up wi-fi and security with an encryption key

Configuring the security of a wi-fi network using filtering by MAC address

Configuring the Netgear WG602 Access Point

Setting up a wi-fi access point Netgear WG602 is quite simple . Before starting the connection, hold down the "Reset" button, which is located on the back of the access point for 20 seconds to reset all settings to default. Remember that if you use an Internet connection through a login-password pair, then you need an access point with support for the PPPoE protocol, the connection of which is described above, the Netgear WG602 access point cannot be used with this type of Internet connection.

We connect the Netgear wg602 access point to the network card of the computer with a twisted pair cable. In the connection settings of the network adapter (card) of the computer, we prescribe IP 192.168.0.2, mask 255.255.255.0, deleting the previous settings, if any, but you can also use a second network card on the motherboard to configure an access point.

Open a browser to connect to the web interface of the access point, write in the address bar 192.168.0.227, a dialog box should appear where you need to enter login: admin password: password (setting data is written on the bottom cover of your access point)

We go to the Wireless Settings menu, type an arbitrary network name - Wireless Network Name (SSID) and region (Country / Region), click "Apply".

Now we need to go to IP settings and “drive in” the provider settings from the contract by unchecking DHCP. This checkbox will not need to be unchecked only for those whose provider assigns an IP automatically or you use a wired router (switch) with an IP assigned to it. Such routers are necessary to connect several devices in the apartment. Leave all other settings as default.

We reboot the access point (go to the Reboot AP menu section), remove the cable from the computer's network card:

1) If you have an Internet cable connected to the aforementioned switch with an assigned IP provider, then the end of the cable that you pulled out of the computer, insert into the switch and connect to the newly made Wi-Fi network using any device that supports this wireless technology, entering only a password (for example, a smartphone). Skip this paragraph if you are not using such a router.

2) If you have only a cable from the provider in your apartment (house, office), then also remove the end of the cable pulled out of the computer from the access point and connect the cable of the Internet provider to it. Check network health.
