I changed the modem and how to set up wifi. Errors in setup and incorrect operation of the Wi-Fi network

Plug the Internet cable into the WAN (or Internet) port of your router (aka router).

Connect the router to the computer: insert one end of the network cable into any of the LAN ports of the router, and the other into the connector of the PC’s network card. You can use a wireless connection instead of a cable, but it is better not to do this at the setup stage.

Connect the router to a power outlet. If your device has a power button, press it. Then wait a minute or two to allow the router to boot up.

2. Check the Internet

If your router was pre-configured by your provider or received settings automatically, then the Internet can start working a few seconds after connecting the router to the PC.

To check, launch your browser and try opening several sites. If there are no problems with accessing web resources, you can skip the fourth paragraph of the article.

In your browser's address bar, enter 192.168.1.1 or 192.168.0.1 and press Enter. One of these IP addresses should lead to the router's settings menu. If both options do not work, find the required IP address in the documentation for your router model and try entering it.

When the settings login page appears in the browser window, the system may request a login and password. Most often, when connecting for the first time, one word is suitable for both fields - admin. Less often, router manufacturers use the combination as a standard password 1234 .

If necessary, you can find the login information in the instructions for the router or on the provider's website. Well, or try an alternative.

4. Set up an Internet connection

If the Internet still does not work, the router needs special settings. Exactly what settings you need depends on your specific device model and Internet service provider. There is no universal configuration. To get the necessary instructions, check the provider's website or request it from support.

Once you have obtained the manual for setting up your model, follow its prompts. If in the process you set up both an Internet connection and a home Wi-Fi network, you can skip the fifth point of the article.

For Wi-Fi, it is important to choose the right security settings.

In the settings menu, find the section responsible for the wireless network (see the documentation for your router model). Here, be sure to set a strong password (you will need it to connect your devices to the router via Wi-Fi) and select WPA2-PSK as a means of protection.

6. Change the password to enter the router settings

Just in case, it is better to limit the access of strangers to the router settings menu. If the router is still protected by the default password, replace it with your own.

Find the settings section that is responsible for the security (see the documentation for your router model) of the device, and enter a new strong password here. Save your changes.

If your computer has a Wi-Fi module, after completing the setup, you can remove the network cable from the PC and connect to the router via a wireless connection.

7. Install the router in the optimal location

Ideally, the router is in the center of the area in which you use Wi-Fi. This way the signal will be equally available to all connected devices.

The fewer walls, furniture, and other obstacles between the receiving device and the router, the better the wireless network works.

Based on the name, a reasonable question arises: why do you need to connect the router through the router, what is the meaning of these actions. The fact is that users are often faced with a situation where the Wi-Fi signal is not able to cover the entire area of their homes. This is a common occurrence for large private houses, for example, with an area of 100 m3 or more. Regardless of the model, routers have a limited coverage area, and to increase it, repeaters are used that can “expand” the space significantly. For the same purpose, two routers are connected to each other using a connection to the same network. The second router performs the function of a repeater, thus achieving both its expansion and expansion.

Important to know! When setting up such a connection scheme, when you need to connect two routers in order to expand the existing Wi-Fi network, you will need to configure the router in repeater mode. But this method is not suitable for all devices; some models do not support this function.

To connect router to router, a LAN cable is most often used. This is easy to do: no specific skills are required, and it does not take much time. But not everyone knows how to connect a router to another router via cable. It is naive to believe that it is enough to connect one device to another and everything will work. No, of course, you will need to delve a little into the process and understand the intricacies, since there are two completely different connection schemes. Before taking any action, you should familiarize yourself with both, and then choose the most suitable option for yourself.

Network of routers cascaded LAN-WAN

This scheme is preferable for the majority of users, in any case, it is used more often. First, you need to figure out how to properly connect two routers with a cable: from the LAN socket to the WAN input. This is done for a simplified way of setting up the Internet, which will be a feasible task even for beginners in this matter. A tree-like Wi-Fi bridge is built using this principle: in this way, you can connect countless routers using one access point.

But first, this chain needs to be established. It is noteworthy that the last device in this chain uses the settings of the previous one, and this simplifies the task. The process of how to connect and connect two routers actually comes down to the fact that you need to enable the dhcp function on the main router:

After the changes are saved, wait until the connection appears and work quietly.

Communication between routers using an equivalent LAN-LAN scheme

With this option, you need to connect the routers with LAN ports, using a cable by sequentially inserting it into the LAN port of one device, and in the opposite direction. Such a connection creates one logical segment, and wireless networks must have different SSID names with the same addressing. To configure and connect, unlike the previous method, you need, on the contrary, to disable the DHCP server. To do this, first go to the web interface of the primary router, the DHCP server tab, and remember the pool of distributed addresses. By default, the range of values is from 2 to 100:

Open the settings of the secondary device, go to “Network” - “Local network”.
If they have the same IP address, it needs to be changed. The address is not selected from the DHCP server pool, that is, we set the value to 192.168.1.101 or something like that.
Go to “DHCP Settings”, disable the server by checking the box next to “Disable”.
Click on the “Save” button, then reboot. We managed to connect.

Wireless connection

There is another recognized option for how to connect a router to another router via wifi. Connect them together by creating a wireless “Wi-Fi” bridge, as a result of which you can install routers at a great distance from each other, while increasing the coverage area. In this case, cables will not be needed, this is a positive thing: they will not interfere. But this option is not without its negative sides: it’s easy to connect, but the network loses stability, which is accompanied by a decrease in speed. If there are serious reasons not to use a cable for the connection, this would not be the worst option. When using the wireless method of connecting and connecting routers, you should keep in mind that not all devices support WDS mode; this mainly applies to outdated models.

Wireless bridge based on WDS

A wireless network bridge can be created simply by connecting two routers into one Wi-Fi network, but the process itself is complex and lengthy. The detailed settings methods differ on different routers, but the principle of creating such a bridge with your own hands is unchanged: this requires WDS support.

To expand coverage, it is recommended to connect and connect one router to another via Wi-Fi, using devices of the same brand. In other words, if the main router is, for example, Asus, the operation and connection will be more stable when using an additional device of the same brand.

Configuring the main router for WDS mode

Different routers have their own settings, and many manuals have been published on this matter. But the process and sequence of actions described in them are so complex and confusing that a novice user is simply lost. And the principle of how to configure a router (main) in order to connect with an additional one comes down to one thing, regardless of the device model:

Setting up a second router for WDS mode

Everything is a little more complicated here, but figuring out how to set up a WDS wireless bridge for the second router before connecting is also not difficult. Setting up a router in bridge mode for an additional device looks like this:

First change the IP address of this device.
Set an identical channel as the main one, the same value is indicated.
Enable the “bridge” function (WDS) by checking the box.
Designate the network name (SSID) used by the main device.
Next you need to enter the mac address of the main router.
Specify its password, key type and Wi-Fi network password.
When you enable the WDS function, a Search button will appear. Click on it to scan available networks.
Select the desired network - “Connect”.
Specify the “Key Type” and “Password” of the main device network, then “Save”.
Go to “DHCP Settings”, disable the DHCP server.
Click on the “Save” button and reload. We managed to connect.

Connecting an access point (AP) to the router

Before connecting both routers to create and configure a wireless bridge, connecting them to each other, you will need to update the firmware and begin setting up the access point, which will help expand the coverage radius. The connection will help create a distributed network using multiple APs to obtain a connection through both devices.

Connecting APs to each other

In order to connect two devices, the process begins by entering the router address into the browser search engine via: http://192.168.1.1. Then press Enter and enter the user details in the registration window: admin and admin. Next, go to the router’s web interface:

In the settings, select “Wireless networks”.
In the network name - SSID - indicate the name, for example, WL550gE, and in the WPA2-PSK column create a password for the wireless network. Remember it or write it down.
In the IP Config folder, open WAN & LAN, where the IP address of the first access point is indicated. Remember it.
In the “Wireless Networks” folder, select “Bridge”.
In the new window, find AP Mode, where you select “Mixed Mode”, and as a bridge - the WDS Only option.
Here select a fixed WDS channel, value 1, 6 or 11.
Activate the “Connect to access points in the list of remote bridges” function.
Enter the MAC address of the second access point with the value 00:0E:A6:A1:3F:6E – “Add”.
Click on the “Finish” button, then “Save and Reload”.

Setting up a second AP

To connect the second router to the access point and connect to the first, a similar sequence of actions is used. Then go directly to the device settings:

Open the menu and specify the network name (SSID), it must match the first AP.
Open the DHCP server in the IP Config menu.
In the “Enable DHCP server” line, select “No”, then “Apply”.
In the “Bridge” menu, specify the same channel as the first AP.
Enter the MAC address of the first access point with the value 00:0E:A6:A1:3F:87 – “Add”.
In the “Password” field, you must enter the code word created by the user for “WPA2-PSK” in the first router.
Click on the “Finish” button, and then “Save and Reload”.

Conclusion

The process of how to connect and connect one router through another can be difficult or easy depending on the option chosen. But first you need to ask yourself questions: is it worth it and why are we combining routers? If the answer is yes, and the goal is clear, all that remains is to choose the most preferable method to connect both devices into one.

In this article we will take a detailed look at the process of connecting a laptop or Windows 7 computer to the Internet via Wi-Fi. I think the article will be useful to many, since many questions always arise when connecting to Wi-Fi for the first time. As a rule, they are associated with installing the necessary drivers, enabling the wireless adapter on the laptop, etc. More on this a little later.

The laptop is generally a great thing. I don’t really understand people who are buying desktop computers now. Only for serious games. Well, you must admit, it’s much more convenient with a laptop. If you want a big screen, you can connect it to a monitor or TV. It makes no noise and you can take it with you if necessary. And also, all modern (and not so modern) laptops have a built-in Wi-Fi module. A receiver that allows you to connect your laptop to the Internet via a wireless Wi-Fi network. In the case of a desktop computer, you will need to buy .

All you need is to buy and install (if you don't have it yet), it will distribute Wi-Fi to which you connect your laptop. You can connect your computer to a free Wi-Fi network in cafes, shops, etc. Or, to your neighbor’s unprotected network :) This is much more convenient than laying a network cable. While this is still normal for a regular desktop computer, it is no longer the same for a laptop. And it’s not convenient to move around the house with this wire all the time.

Connecting a laptop to the Internet is not difficult, provided that the Wi-Fi driver is installed. Many people have a lot of problems because of the driver. If you simply did not install the driver for your Wi-Fi receiver, or you installed Windows yourself and did not install it, then you will not be able to connect to Wi-Fi. But you may already have everything installed and configured, so let’s first look at the process of connecting to a wireless network normally. If you fail to learn, there is no wireless connection, etc., then read the article to the end, we will look at possible problems.

Connecting the laptop to Wi-Fi

Let's first look at the connection process without any settings or checks. Why complicate everything, perhaps you already have everything set up. If everything is fine, your laptop sees the wireless network and is ready to connect, then the Internet connection icon in the notification panel will look like this:

Connection status, which looks like network level with an asterisk (like the picture above) indicates that the laptop sees available networks and is ready to connect to them. Click on this icon, then select the Wi-Fi network to which we need to connect and click the button Connection. In Windows 10, the process of connecting to Wi-Fi is slightly different. If necessary, detailed instructions.

If the network is password protected, a window will appear in which you need to enter a password and confirm the connection by pressing the button Ok.

That's all, your laptop should connect to the Wi-Fi network. The connection status will be like this:

You can use the Internet.

If you see the connection status, it looks like this:

This means that most likely everything is configured on your laptop, but the laptop simply does not see the networks available for connection. Perhaps there is simply no coverage in this place. If you are connecting to your network, check that the router is turned on. If enabled, then .

This is how the connection will proceed when you have the driver installed for the Wi-Fi adapter and the adapter itself is turned on. But very often the adapter on the laptop is turned off, or no one installed the driver for it at all. In such cases, many questions arise. Now we will examine in detail both cases, due to which you may have problems connecting your laptop to a wireless network.

Enable "Wireless network connection" on the laptop

If your wireless connection is disabled, or the Wi-Fi driver is not installed, the connection status will look like this:

This means that there is no way to connect to the Internet via Wi-Fi, and there is no connection via a network cable. As I wrote above, this happens due to the adapter being turned off, or due to the lack of a driver. Let's first check if your "Wireless Network Connection" is disabled. This is of course unlikely, unless you turned it off yourself, but you need to check.

Click on the internet connection icon and select Network and Sharing Center.

Then select Changing adapter settings.

Looking at the adapter "Wireless network connection", if it is disabled, then right-click on it and select Turn on.

After this, the connection status "There are available connections" should appear. (if there is a Wi-Fi network within the radius).

We enable wireless connections using the buttons on the laptop

It seems to me that now manufacturers no longer install separate buttons to turn on the Wi-Fi adapter. But, if you are having problems connecting to Wi-Fi, then be sure to check if there is a special button to disable/enable wireless connections on your laptop. I know for sure that Toshiba loved making such switches.

Nowadays, on laptops, a keyboard shortcut is used to disable/enable the wireless network. As a rule, different manufacturers have different keys. But usually it's Fn+F2. So on Asus laptops. You can look at yourself, there should be a network icon on the key that is pressed in conjunction with Fn. Something like this:

True, for me the combination of these buttons is responsible for turning off Bluetooth. It doesn't seem to respond to Wi-Fi at all. But yours may be different. It's definitely worth checking out.

If in the adapter management window there is no “Wireless network connection” adapter at all, but there is definitely Wi-Fi on your computer/laptop, then this means that The driver for the Wi-Fi adapter is not installed.

Now we will check everything and try to solve this problem.

Check and install the driver for Wi-Fi

I have not yet seen a case where after installing Windows 7, the system itself installed the driver for the Wi-Fi adapter. This is much better in Windows 8. Windows 10 often installs the necessary drivers itself. So, after installing Windows, in order to use Wi-Fi, you need to install a driver specifically for your laptop or adapter (very often, adapters from different manufacturers are installed in one laptop model. It is because of this that you can see several drivers for Wi-Fi on the manufacturer’s website).

We go to the device manager.

In Device Manager, open the tab Network adapters, and looking for a driver for Wi-Fi. I have it called Atheros AR9485WB-EG Wireless Network Adapter, it is installed. You should also have something like a Wireless Network Adapter.

If you don’t have a wireless connection, then most likely you won’t find an adapter either. You need to install the driver, then Wi-Fi will work. And also, if the driver for the Wireless Network Adapter is not installed, then in the device manager there will be at least one unknown device with a yellow exclamation mark. It looks something like this:

This is most likely the same Wireless adapter that the laptop does not know how to work with.

Driver installation

All you need to do is download the required driver and install it. It is best to download the driver from the official website of the manufacturer of your laptop/adapter, and for your laptop (or adapter) model. It’s best to find the official website of your laptop, for example Asus, through Google, then use the site search on the site, indicating the model of your laptop. Most likely your computer's page will be found, open it and look for downloads of utilities and drivers there. Find the Wireless driver and download it for the operating system you need.

Most likely, the driver will be in the archive. To install, run the .exe file from the archive. For example, an archive with a driver for my laptop:

After installing the driver, restart the laptop and try to connect to the wireless network, according to the instructions. I wrote in more detail about installing the driver in the article about .

If some points from the article remain unclear to you, or you were unable to connect your computer to Wi-Fi, then write about it in the comments, we will try to solve your problem.

Almost every laptop has the ability to connect to wireless.

Using this technology, computers exchange data between themselves and network devices (printers, access points, etc.), and also access the World Wide Web.

There are many laptop models, but they all work according to the same communication standards. Can you imagine what their owners would have to do if each laptop did it differently?

Many laptops - one Wi-Fi

The procedure for setting up a wireless network depends only on the operating system.

Some manufacturers equip their laptops with network utilities, but this does not provide anything new, except that it makes the setup process more convenient.

Of course, you can use them, but it is more useful to know how to work with OS tools.

If you figure out how to set up WIFI on Windows 7, 8 and XP using the system, you can do this on any laptop, regardless of the model.

Three conditions for turning on Wi-Fi for the first time

Before you connect your laptop to the Wi-Fi network for the first time, you need to do three things:

turn on the wireless adapter (also called a WLAN or wireless network card);
start the WLAN autoconfiguration service.

Step 1. Enabling the Wi-Fi adapter

To turn on the Wi-Fi adapter on the laptop, there may be a button or key combination: Fn + [one of the keys F1 -F12, where the Wi-Fi icon is shown].

You can tell that the adapter is turned on by the glow of the indicator on the laptop case:

Step 2. Driver installation

Important! Networks marked with a shield icon with an exclamation point do not require a password. They are not protected in any way, and data is transmitted through them in clear text.

Step 4. Connect to a hidden network and change the communication profile

To connect to an invisible network whose name is hidden, as well as to create a new wireless access profile, right-click on the “Network” icon in the tray and enter “Network Center...”.

In the “Change network settings” list in Windows 7, click “Set up a new connection or network”, and in Windows 8 (8.1) click “Create and set up a new connection or network”.

Select "Connect to a wireless network manually." This window, like the following ones, looks the same in Windows 8 and 7, so let’s look at the setting using Windows 8 as an example.

Enter the access point name (SSID), security type, encryption and password. If you are going to use this network constantly, check the “Start connection automatically” checkbox.

The “Connect if the network is not broadcasting” option should be checked when the access point is not visible in the list.

In the next window, you can change the connection parameters by clicking the button of the same name.

Basic parameters - name (SSID), grid type and availability cannot be changed. Security settings can be changed, but they must be the same as those assigned to the access point.

Step 5. Connecting and setting up Wi-Fi on Windows XP

To connect your laptop to existing Wi-Fi networks, right-click on the “Network” icon in the tray and open “View available wireless networks.”

Select the desired access point from the list and click “Connect”.

Enter the password (security key) and its confirmation. After clicking on the “Connect” button, the connection will be established.

Instructions

The situation is simplified thanks to the presence of a wifi module in the vast majority of modern laptop models. Naturally, having become the owner of a laptop with a wifi module, everyone wants to quickly join the benefits of technological progress in the form of access to a variety of wireless networks. However, before plunging into the abyss of the wireless Internet, you need to configure wifi to.

First of all, you need to turn on the laptop's wifi module. As a rule, one of the keys on his keyboard is intended for this, marked with an antenna icon and working in combination with the Fn function key. If there is an indicator on the laptop case marked with the same icon, then if the wifi module is successfully turned on, it will light up.

Configure your laptop's network settings so that it receives an IP address automatically. As a rule, this is quite enough to successfully detect wifi networks and connect to those that provide free access.

Having detected available wifi networks, the operating system will display information about them and offer to connect to them. Click on the message that appears in the tray, follow a few simple steps suggested by the connection wizard, and you are online.

If you are prompted for an SSID when you try to connect to a wireless network, it means that the selected network is not one and is protected by a special code. It is impossible to gain access to such a network without knowing the code. However, if you see the SSID request, it means you managed to configure wifi correctly. If there are several items in the list of available wireless networks, try connecting to other networks (they may be public) or purchase an access card to a paid network, it will indicate the SSID.

Built-in Wi-Fi allows you to surf the Internet anywhere there is Wi-Fi. But before you are going to connect to Wi-Fi, check whether a wireless network card is connected to your device (in this case, a laptop). Most mini-computer models have a button with a Wi-Fi icon on it. The laptop must also have a special indicator. It lights up when “ ” is connected. Depending on the laptop model, the indicator may light up in different colors. When the “network card” is disabled, the indicator lights up in red; when the “network card” is turned on, the indicator lights up in white or green.

Some laptop manufacturers place the Wi-Fi switch at the end of the laptop case. For the convenience of the user, symbols are placed nearby, which make it clear how to turn Wi-Fi on and off.

If your (laptop) is running Windows XP, click the Start button in the lower right corner of your desktop. Then go to Control Panel. Click the “Switch to classic view” button to make it easier to navigate further settings. . . Select the "Network Connections" section. The “Wireless network connection” icon will appear in a new window; it must be active. Right-click on it and select “View available wireless networks.” After this, a list of available wireless networks will open in a new window.

Select the network you need. If it is under a password, enter it twice in the appropriate field in the table that opens. After completing these simple steps, it will connect to the selected access point and you will be able to use the Internet.

Users of the Windows 7 operating system can find available connections by clicking the “Available Connections” icon located on the toolbar next to the clock icon. If you don’t visually know the icon you need, move your mouse cursor to all the “shortcut” images on the panel and read what this or that “picture” means.

Click the button you need and wait until a new window opens with a list of available Internet connections. From the list presented, select the desired network, and if required, in the window that appears after this, enter the password - the network security key. After completing this step, you can easily connect to the Internet.

A network security key, or password, is a coded cipher that allows you to connect to a working Wi-Fi network. It directly affects the secure operation of the wireless network. Like all passwords, the security key protects the Wi-Fi user (owner) from illegally connecting to the network. Internet connection at work
