To do this, go to the system tools tab and select the “Password” sub-item. Then you will need to enter new keys and save them, and then restart the device.

Possible problems during connection and setup

Usually independent connection WiFi- TP-Link router does not cause any difficulties.

But in some cases the following problems may arise:

The computer does not recognize the set-top box. In this case, you need to connect the router to another gadget or reboot it.
The router interface does not open. Some device models are not compatible with the browser Google Chrome, and in this case it is advisable to log in from another gadget.
The settings menu does not load. In this case, you will need to check the settings wireless connection, IP and DNS addresses must be set in automatic mode, as evidenced by the checkboxes next to these items. If they are removed, you need to put them back on.
I can’t enter the menu at the address specified on the router panel. In such situations, the reason may be that the data was entered incorrectly, or that it was changed after the set-top box was installed. In the first case, you will need to check the correctness of the recorded combination, and in the second, “roll back” the settings to the factory settings by pressing the “reset” button on the panel and holding it for 10-15 seconds. After this, when logging in, the data registered on the device panel is indicated.
After setting up the set-top box, access to the Internet was not obtained. The reason for such trouble may be problems on the part of the provider. To confirm or deny this, you need to connect your PC to the network directly and check the connection activity. In other cases, you cannot access the Internet because the cables are not connected correctly or are damaged and need to be replaced. If this doesn't help, the router may be faulty.

TP-Link Wi-Fi routers are rightfully considered one of the best - as a rule, they combine affordable price And good quality. U ordinary users Routers model TL-WR841N or TL-WR841ND are especially popular. However, you need to understand that stable work device is only possible if it is configured correctly.

Setup instructions

Many people are afraid to configure the TP-Link router themselves, especially in cases where the computer is connected to the Internet via a modem (fiber optic, cable or ADSL). However, there is nothing complicated in this procedure. The instructions below apply to everyone. modern models router (not older than five years) - appearance The menu may differ, but the settings remain the same.

Manipulations are performed in the following sequence:

Connecting the router to the network and computer.
Setting up WAN and Wi-Fi.
Setting a wireless network password.
Change the password to protect your router settings.

Before you perform any connection actions, you need to check what network parameters you have set:

PPPoE - users can connect to the Internet only after entering their login and password.
Static IP - to connect, the user must manually enter the parameters (IP address, ) issued by the service provider.
Dynamic IP - connection parameters are set automatically via DHCP.

If you have Dynamic I.P. installed (in Lately this is the most common option), when setting up the router, there will be no problems with obtaining an IP - all the necessary parameters will be set automatically. For other connection options You will most likely need to contact your provider and check with them.

A separate situation is if the provider deliberately blocks new connections by MAC address. In this case, you need to try to clone the MAC address in the appropriate router settings item in order to assign it the same address as on the computer. You can also call your provider while connecting the router and ask him to change the MAC address. However, if your agreement with your service provider contains a clause stating that you agree to connect only one computer to each outlet and use only the provider's router, it is unlikely that you will be able to connect TP-Link.

Connecting a TP-Link router

Let's look at it step by step, how to connect a TP-Link router to a laptop or PC:

Please note: when connecting via a modem, the latter must be connected to the router using the WAN-WAN scheme, while the router is connected to the PC via a LAN connector. If at this stage you accidentally mix up the cables, the connection will not work - you will end up with a network without Internet access.

Setting up an Internet connection

Now let's figure out how to set up WiFi on Tp-Link. So, the first thing you need to do is enter the router settings. To do this, enter the numbers 192.168.1.1 or 192.168.0.1 into the address bar of any web browser. After this, a small pop-up window should appear asking for a username and password. In both fields you need to enter the word admin. By the way, the default username and password can be found on the sticker at the bottom of the router.

If the standard username and password do not work, you will need to reset your router to factory settings. To do this, press something sharp on the Reset button, which is located behind, and hold for 10 seconds.

In rare cases, when you try to access your device settings, you may receive an error message from your provider (for example, a page notifying you that your account is out of money when in fact it is not). Don't panic - just try logging into settings through a different browser.

The connection is configured like this:

The same operations can be performed in the Quick Setup menu. If you're worried about accidentally clicking the wrong thing, use this feature.

If the process was successful, in the list of networks of your devices (phone, tablet, etc.) will appear available network Wi-Fi with the name you specified earlier. To connect to it, enter the password written in the PSK Password column (do not confuse it with the settings password).

Changing the Settings Password

Unlike the previous ones, these steps are not mandatory - the password can be left as standard. However, please note what's in the router settings, among other things, the password with which you protect your wireless network. This means that strangers can use your network - to find out the password, they only need to enter the device settings.

To prevent this from happening, you must do the following:

If you are unable to complete the setup, go to the official TP-Link website, go to the FAQ section and look for a description of your problem in the list of frequently asked questions. By the way, on the official website you can download the most fresh drivers For various models TP-Link router.

In addition, it should be remembered that Internet problems may be caused by not only by your actions - perhaps some problems have arisen on the side of the provider or with the router itself. Try disconnecting the router from the computer and connecting to the Internet directly - if there is still no network, most likely the problem is on the ISP side. Wait for the moment when network connection will resume and try to configure the router again. To clarify the problem, you can call the service provider back.

If, when connected to a PC, the router shows no signs of life (the indicators do not light up), and at the same time you are sure that you did everything correctly, the problem is in the device itself. IN in this case Only specialists from the service center will help.

Determining your Internet provider's network settings

Before connecting the router, you need to know what network settings needed to connect to the Internet.

The most common types of network settings are:

Dynamic IP— dynamic settings, issued automatically via DHCP
Static IP — static settings, entered manually
PPPoE— Internet access is provided via the PPPoE protocol after entering the username and password

It is assumed that you have Windows 7 installed, the provider cable is connected to the computer and Internet access is configured.

Go to "Change adapter settings".

Click right click mouse on "Connect via local network" and select "Properties"

Click on “Internet Protocol Version 4 (TCP/IPv4)” and the “Properties” button.

If you have selected “Use the following IP address” and there are numbers, then write down all settings- these are the static settings of the provider ( Static IP). After that, select “Obtain an IP address automatically” and click the “OK” button.
If you select the “Obtain an IP address automatically” option, then you receive network settings automatically - these are the dynamic settings of the provider via DHCP ( Dynamic IP).

There are providers that block access to the Internet via MAC address(can be found in the contract). In this case, you need to configure the router so that it has the same MAC address that is registered with the provider.

To find out the MAC address network card, click “Start”, in the “Search programs and files” window write the command cmd and press Enter.

We write the command in the console ipconfig /all and press Enter.

We are looking for “Ethernet adapter Connection via local network...”

In field " Physical adress"Your MAC address of the network card is indicated. Let's rewrite it.

The note! Specify this procedure from the supplier, you may not need it.
Typically, the purpose of this setting is simply to gain access to the Internet for family use, for which you need to understand the “settings” submenu wireless mode" Indicate in it the desired name of the Wi-Fi network and the region of your stay. In the “mode” column, it is advisable to select “11bgn mixed”, it is suitable for 99% of users. We also recommend leaving the channel width and channel in auto mode. Under Maximum transfer speed, select greatest number according to the principle “the more the better” (300 Mbit/s).

Interesting! If they are used at home modern smartphones, laptops or computers no older than 3– 4 years (which have new type network cards), then in the mode column you can select« 11n» - this will provide a higher streaming data transfer rate, and will also make both antennas active in constant mode.

If you want to stabilize and at the same time slightly increase the Internet speed, select the channel manually. Many people live in multi-storey buildings and use the Internet from a single provider, so with automatic channel selection mode, for some it may be the same, thereby reducing the speed. To select the optimal one, install the “Wi-Fi Analyzer” application on Android and find the less used channel - select it in the settings.

How to connect a router

The router package includes:

Router TL-WR841N;
Power adapter;
Ethernet cable with RJ-45 connectors;
CD for quick setup;
Management.

We unpack the box and proceed to installing and connecting the router. First, connect the device to power using the adapter and click on Power button on the rear panel (if the indicators on the router light up on their own after power is applied, then you do not need to press the button).

Next, using the included Ethernet cable connect the router and computer. We plug one end of the cable into one of the four yellow LAN ports of the router, and the other into the connector of the PC’s network card. Then we connect the cable coming from the Internet provider or ADSL modem to the blue WAN connector of the router.

In principle, that’s all, now you can proceed directly to setting up the router, but first let’s make a reservation that along with it comes a CD with a utility that allows you to quick setup router in step-by-step mode. We will not consider this method, because the configuration option via the web interface is more preferable.

Basic setup of the TP-Link TL-WR841N router

Since the router will now be responsible for connecting to the Internet and distributing it, the need for the previously created in Windows high speed connection No. At the same time, the connection via the local network connecting your computer and router needs to be configured. Let's go to Control Panel - Network and Sharing Center shared access- Change adapter settings. Right-click on the active connection and select “Properties”.

On the “Network” tab, set the switches to “Obtain an IP address automatically” and “Obtain a DNS server address automatically.”

Also in position automatic settings We put a switch on the “Alternative configuration” tab. Save the changes with the “OK” button.

Now we launch any browser and in address bar we register http://tplinklogin.net/ or 192.168.0.1 . Then in the window that opens, enter the username and password - by default this is admin And admin.

The standard username and password are indicated on the label on the bottom of the router. Look at it and make sure once again that all login information for the web interface TP-Link settings TL-WR841N entered correctly.

If everything is done correctly, you will be taken to the administration panel. Here we immediately go to the Internet settings.

Internet setup (WAN)

Select “Network” from the menu on the left (in the English interface – Network), and then the WAN section. In the “WAN Connection Type” drop-down list, select desired type connection to the provider.

The following options exist:

Dynamic IP address;
Static IP address;
PPPoE;
L2TP;
PPTP.

There is no point in delving into the essence of all these types of connections. Information on which one to choose is provided by the provider. The Internet service provider also transfers authorization data to the client - username and password. If you suddenly forgot this data, you can look it up in the contract. The second option is to call the provider's support service.

So, we configure the WAN connection according to the following schemes:

When choosing dynamic IP address no additional actions no need to produce;
Option Static IP address requires entering the IP address, subnet mask, gateway and DNS. We remind you that all this data is provided by the service provider, i.e. your provider.
Connection type PPPoE requires entering a username and password.
When selecting a connection L2TP indicate the username, password and IP address/VPN server name.
Connection type PPTP will also require you to enter your username, password and IP address/VPN server name.

After all the data has been entered, click the “Save” button. The Internet should work.

After setting up the Wi-Fi router TP-Link TL-WR841N there is no Internet access

If you have configured everything exactly according to the instructions, but as a result the Internet does not work, you need to do the following:

If none of the above steps help, the router may be faulty. To make sure the device is working, try connecting it with friends or acquaintances.

Wi-Fi setup

Providing a wireless connection to the Internet is one of the most important functions of a router. Let's move on to the Wi-Fi settings for TP-Link TL-WR841N.

Go to the section Wireless Mode - Wireless Settings (Wireless – Wireless Settings). Set the name of our Wi-Fi network and select the region.

Below are network settings that may affect signal quality and coverage in certain situations. We will not focus on them, since this is a topic for a separate large conversation. Leave all settings at their default values and save your settings.

Now we need to protect our wireless network from unauthorized connections of third-party users. Select “Wireless Security” on the left.

Set the switch to the “WPA/WPA2 - Personal (recommended)” position. Next, select the version, encryption type and set a password. We save the changes made.

Setting a new administrator password

The standard username and password for accessing administrative settings make your TP-Link TL-WR841N router very vulnerable, so it is better to change them immediately. Let's move along the path System Tools- Password (System Tools - Password). Here we enter the old and new authorization data (you can only change the password and leave the username as admin), and then click “Save”.

You can write down your password somewhere so you don’t forget it.

Perhaps this is it basic setup Wi-Fi router TP-Link TL-WR841N is completed. Of course, there are still a lot of different functions that can be useful to users. However, this will be a more subtle configuration that requires a separate article. We achieved the main goal - we set up the Internet and Wi-Fi.

For all settings to take effect, reboot the router. It can be done programmatically through section ( System Tools - Reboot) or physically by turning off the power. After loading, a Wi-Fi network should appear with given name, to connect to which you will need to enter a password. The Internet must work in both wired and wireless mode.
