Problems with WiFi router - diagnosis and solution. Problems with Wi-Fi router

In this article we will talk about troubleshooting common problems with Wi-Fi routers.

After setting up the router, problems may occur. Among all the problems, the most common ones are:

Frequent loss of connection and poor Wi-Fi speed

If the connection is constantly disconnected and the download speed via Wi-Fi is very low, it is recommended to change the wireless network channel. An important point: this will not help eliminate router freezes.

Also check the firmware version of your equipment and update if necessary. Look for reviews from other users about your provider; perhaps solutions to the problem have already been found.

WAN breaks

In most cases, the reason for this is that the desktop computer is connected via WAN. Only one WAN connection is available to the user, and if it is used by a computer, the router will not be able to connect the WAN and “distribute” the network to other devices. To fix the problem, you will need to remove the separate connection to the provider on your desktop computer by setting up a local network connection.

I can't access the router settings page

If your browser does not open page 192.168.0.1 or 192.168.1.1 with router settings,

1. Enter the address directly into the address bar, rather than into the search box.

2. Check connection settings. Having selected a local network connection, check the boxes: obtain an IP address automatically and obtain DNS automatically.

3. Use the “Run” command (Win + R keys). Type cmd and press Enter. Enter the ipconfig request. Among the displayed data, find “Default Gateway”. You need this address to configure the router. If there is no address in this item, reset the settings on the router. You can also try disconnecting the ISP Internet cable from the router, leaving only the one connecting it to the computer. Configure the router again, and then connect the cord to the router.

If there is no address in this item, reset the settings on the router. You can also try disconnecting the ISP Internet cable from the router, leaving only the one connecting it to the computer. Configure the router again, and then connect the cord to the router.

Router settings are not saved

If after entering the settings, they are not saved, try repeating the same thing in another browser. This is also recommended if you have problems setting up your router.

Laptop, tablet, smartphone does not see the Wi-Fi network

If wireless networks are not displayed on your device, first check whether the wireless module is turned on.

On Windows laptops, this can be done in the Adapter Settings section of Network and Sharing Center. Check if your wireless connection is turned on. The problem may be exactly this. Your laptop may have an external Wi-Fi switch. It must be enabled.

If the problem is not resolved, check the installed drivers of your Wi-Fi adapter. Perhaps they need to be updated. Updates are located on the laptop manufacturer's website, but look for drivers specifically for your model.

If the above methods did not help, try changing the router settings. Put b/g/ instead of b/g/n. Did it help? This means your device is not compatible with the 802.11n standard. If there is still no connection, specify the Wi-Fi network channel manually.

On tablets (often iPads), the same problem can be solved by changing the Russia region to United States in the router settings.

Torrent or other resources do not work

Some Internet providers restrict access to torrents or game servers. You will need special settings for static routes in your router. Most likely, you will find all the necessary information on the forums of your provider.

Setting up the DIR-300 NRU router is not working, please help with advice. I bought this model of router. The store reassured me, they said that it is the easiest to install and almost all Russian Internet providers work with it, and all of them have instructions for installing it on their official websites. Of course, there were no instructions for this model on our provider’s website, and I also realized that the DIR-300 router comes in some different revisions b1-b5 (it turned out I had NRU b5). And each Internet provider configures the router differently, or so it seemed to me. As for the manual book that came with the router, it contains a description of connecting the DIR-300NRU b5 to the XP operating system. I want to connect it first to a system unit with the Windows 7 operating system, and then connect my daughter’s laptop to the created virtual network, but it also has Windows 7 installed. I tried to figure it out myself and you know, all these IPoE and PPPoE, PPTP are a headache got sick. So I have a question for you: can I still connect two of our computers to the router or immediately call a specialist like you. And also, explain in Russian what is the difference between WAN and VPN? Vladimir. Samara.

For a long time now, my friends have been asking me to buy and set up a router for them. We go to the store, buy it and set it up step by step, and you watch everything that happens, everything will be clear even to a beginner. You can connect any router, it all depends on your persistence and, of course, patience. Setting up the DIR-300 NRU Router not complicated, this router is extremely popular due to its inexpensive price of 1000-1100 rubles and good reliability and works with the operating systems Windows XP, Windows Vista, Windows 7. On the official websites of Russian providers, there are instructions for installing it, but as I noticed outdated revisions b1, b2, b3, web interface of settings is black and brown.

In 2011, D-Link updated the web interface, now the router settings windows (including the new model DIR-300NRU b5 are pale green, and the background is white; naturally, the settings have changed a little. For providers, everything remains in place. This is for many users, It’s confusing for those who have recently purchased a router. At the moment, according to my observations, the most commonly purchased model is the D-Link DIR-300 NRU b5, which has Wi-Fi support at speeds of up to 150 Mbit, uses an updated settings interface, a built-in firewall and compatibility with non-wireless standards. wired communications 802.11b and 802.11g. I advise you to know exactly what you are buying and check everything in the store.

Attention! Setting up the D-Link DIR-300 NRU router (HW revisions: b1, b2, b3) is slightly different from setting up the DIR-300NRU b5 router, but the essence is basically the same, now you’ll see everything for yourself.

Now about the settings. Before getting onto the Internet (global computer network) from our home, you and I first go to our Internet provider or virtual private network provider (for example, Beeline). There are few real providers in Russia, there are many sub-providers, in simple terms intermediaries. But how to configure the router depends on how these providers organize their network.

How do all providers (providing Internet services) differ and how does this affect the router settings?

Nowadays, one half of the providers use the modern network protocol DHCP or IPoE, where IP and DNS addresses are distributed automatically (I must say very convenient for an Internet provider), and to access the Internet they use an outdated tunnel protocol or a new second-level tunneling protocol L2TP (combining PPTP and L2F).

The other half of the providers work using the outdated PPPoE protocol, associated mainly with xDSL technology (for example Rostelecom), that is, they use DSL modems, in the router settings we again select the PPPoE connection type (information at the end of the article) and configure it a little differently than In the first case. Of course, sometimes there are other features, so before you buy a router, this is my advice to you. Call your provider and find out all the information you need to configure the router, ask about which range of router models to choose from, so as not to have to worry later with settings, firmware and, as you said, specialists like me. Now, let's take a closer look at setting up, in my opinion, a very good router from D-Link, DIR-300NRU b5. In general, I set up this router many times in the seven and in, but unfortunately I didn’t look at the accompanying manual, but it turns out that in fact, as our reader said, nothing is written there about Windows 7, but there is information about XP. Don't worry, our router works fine on both operating systems.

Let's start with the fact that you need to find out what network protocols your Internet provider uses - PPPoE or L2TP, you can find out by looking at the contract with it or you need to call the support service of your provider and just ask, this is the best way, by the way. Let's start with the most common and easiest to configure network protocol today, DHCP. You also need to find out how your provider issues IP addresses; in the case of the DHCP protocol, this happens automatically; you can verify this by looking at the Local Connection Properties of your network adapter.
Windows XP

Start - Control Panel - Network Connections - Local Area Connection - Properties - Internet Protocol (TCP/IP) -Properties - Obtain an IP address automatically And Obtain DNS server address automatically.

Windows 7

Start - type View network connections - Local area connection - Properties - Internet Protocol version 4 (TCP/IPv4) and Properties - Obtain an IP address automatically and Obtain a DNS server address automatically.

If you have the Use the following IP address checked in the Internet Protocol Properties and the addresses are registered, the same addresses must be specified in your agreement with your provider, then your Internet provider works using the PPTP or PPPoE protocol. Let's look at setting up a router with these protocols at the end. But before connecting a router with these protocols, you also need to set the Obtain IP automatically and Obtain DNS server address automatically parameters in the Internet connection properties.
Let's move on to the router settings. If something goes wrong, you can always reset the router to factory settings by pressing the Reset button.
Let's connect the local Internet cable provided by your provider to the WAN port on the router, as we see it says internet on it, and connect the router and your desktop computer to each other with a network cable (in our case, blue) through LAN port No. 1.

Users to whom the Internet is supplied using ADSL technology need to connect the DSL modem and router with a network cable, then connect the router with a network cable to the system unit.

The DIR-300 router has only 4-LAN ports, to which you and I can connect up to 4 personal computers that do not have Wi-Fi.

Turn on the router, open any browser: Chrome, Opera, Mozilla, Internet Explorer and enter 192.168.0.1 in the address bar and press Enter.

And here we are in the initial window of the DIR-300 router. First of all, experienced users download the latest version of firmware (software) for the router from the official website and install it. Currently, our router has the latest version of firmware installed, so there is no need to download or flash anything. And my advice to you, even when the firmware comes out, first try to configure the router as it is, without flashing it, it’s easy for a beginner to make a mistake, and then you can restore the router only at a service center.

Name - Beeline

Connection type - L2TP

Will connect automatically- Put a tick

Service name - tp.internet.beeline.ru

PPP Username - our Beeline login starts with 089...

Password - Your internet password

Encryption - Typically No encryption

The device configuration has been changed- Save so that after restarting the computer, the changes you made to the router settings will be saved.

Next, click Connections again, select the Beeline we just created, Connection type l2tp and assign it Default Gateway(check this item). Click Save.

Click on the button Status - Network Statistics. In the WAN field, you and I see information that our router has successfully received the necessary data from the provider and we have Internet.

Now we connect the laptop to our router via Wi-Fi.

Click the Wi-Fi button in the router settings. General settings . We leave everything as default.

basic settings We don’t touch it either.

Security Settings - Network Authentication or protecting your network from intrusion - select WPA-PSK (Shared Key). Access to your virtual network will be possible only after entering a key known to you and the users of your virtual network.

PSK encryption key: We come up with an encryption key, preferably 10-digit, consisting of letters and numbers in random order, it’s more reliable
WPA encryption – AES or TKIP+AES, then your network will be accessible to almost all existing Wi-Fi devices.
WPA key renewal period leave it as default.

Sometimes it happens that the router's settings are lost when its power is turned off, so be sure to open the "System" menu in the upper right corner of the page and click on " Save and Reload". Now the changed settings of your router will be saved in its non-volatile memory.

Control Panel\Network and Internet \ Network and Sharing Center\Wireless Network Management,

Double click on the network DIR-300 NRU

Properties of the DIR-300 NRU wireless network. Connection tab, you should have a check mark on the item Connect automatically if the network is within range.

In the DIR-300 NRU wireless network properties window, Security tab, check the security settings – Security type,Encryption type, Network Security Key, everything should match the router settings.

Here, friends, are all the settings of our router in the DHCP network protocol.
As for setting up our router in PPPoE mode, you will need to go to the router settings Network -> Connections and select PPPoE connection type, then enter the username and password, as well as confirm the password. Detailed instructions are available on the D-Link website itself - http://dlink.ru/ru/products/5/728.html

Problems setting up a Wi-Fi router.

So, you have configured your wireless router, but for some reason something is not working. I will try to consider the most common problems with Wi-Fi routers and ways to solve them. Most of the problems described can equally occur in Windows 10, 8.1 and Windows 7 and the solutions will be similar.
From my work experience, as well as from the comments on this site, I can identify the following typical problems that users encounter when, it would seem, they have configured everything exactly and according to all sorts of instructions.
The router status indicates that the WAN connection is down
Laptop, tablet, smartphone does not see Wi-Fi, but sees neighbors’ access points
Constant disconnections
Local city resources of the provider, torrent, DC++ hub and others are not available

If I remember other typical things like the above, I’ll add to the list, but for now let’s get started.
(provided that the router is configured correctly)
What to do if when connecting it says:
What to do, if .

Wi-Fi connection disappears and low download speed through the router (through a wire everything is fine)
In this case, changing the wireless network channel can help you. We are not talking about those situations that also occur when the router simply freezes, but only about those when the wireless connection itself disappears on individual devices or in specific places, and it is also impossible to achieve normal Wi-Fi connection speed. You can read more about how to select a free Wi-Fi channel.
WAN is broken or the Internet is only on the computer
The main reason why this problem occurs with a WiFi router is the connected WAN connection on the computer. The point of setting up and operating a wireless router is that it will establish a connection to the Internet on its own, and then “distribute” access to other devices. Thus, if the router is already configured, but the Beeline, Rostelecom, etc. connection available on the computer is in the “connected” state, then the Internet will only work on the computer, and the router will take virtually no part in this. In addition, the router will not be able to connect the WAN, since it is already connected on your computer, and most providers only allow one connection from one user at a time. I don’t know how clearly I was able to explain the logic, but even if it’s not clear, just take it for granted: for everything to work, a separate provider connection on your computer must be disabled. Only a local network connection should be connected, or, in the case of a laptop, etc., a wireless network connection.
It is impossible to access the address 192.168.0.1 to configure the router
If you encounter the fact that when you type the address to access the settings of your router, the corresponding page does not open, do the following.
1) Make sure that in the local network connection settings (your direct connection to the router) it is set to: obtain an IP address automatically, obtain DNS addresses automatically.
UPD: Check whether you enter this address exactly into the address bar - some users, when trying to configure the router, enter it into the search bar, resulting in something like “The page cannot be displayed.”
2) If the previous point did not help, use the run command (Win+R keys, in Windows 8 you can simply start typing the word “Run” on the start screen), enter cmd, press Enter. And in command line mode, enter ipconfig. Pay attention to the “Default Gateway” value of the connection used for configuration - it is at this address that you should go to the router administration page. If this address differs from the standard one, then perhaps the router was previously configured to work on a specific network with certain requirements. You can reset it to factory settings. If there is no address at all at this point, then, again, try resetting the router. If that doesn’t work, you can also try disconnecting the provider’s cable from the router, leaving only the cable that connects it to the PC - this may solve the problem: make the necessary settings without this cable, and after everything is configured, reconnect the provider’s cable. Pay attention to the firmware version and, if relevant, update it. If this does not help, make sure that the “correct” drivers are installed for the computer’s network card. Ideally, download them from the manufacturer's website.
Settings are not saved
If for some reason the settings are not saved after entering them and clicking “save”, and also if you cannot restore the settings previously saved in a separate file, try performing the operation in a different browser. In general, in case of any strange behavior of the router admin panel, you should try this option.
Laptop (tablet, other device) does not see WiFi
In this case, a variety of options are possible and they are all approximately equally common. Let's go in order.
If your laptop does not see the access point, then first of all, check whether the wireless module is turned on. To do this, look at the Network and Sharing Center - Adapter Settings in Windows 7 and Windows 8, or Network Connections on Windows XP. Make sure your wireless connection is turned on. If disabled (displayed in gray), then enable. The problem may have already been resolved. If it doesn’t turn on, see if your laptop has a hardware switch for Wi-Fi (my Sony Vaio, for example, has it).
Let's move on. If the wireless connection is turned on, but is constantly in the “No connection” status, make sure that the required drivers are installed on your Wi-Fi adapter. This is especially true for laptops. Many users, having installed a program to automatically update drivers or have a driver installed automatically by the Windows operating system, believe that this is the right driver. As a result, they often encounter problems. The required driver is the one that is located on the website of your laptop manufacturer and is intended specifically for your model. Laptop computers often use specific hardware, and using drivers (not just for network equipment) recommended by the manufacturer can avoid many problems.

If the previous option did not help you, try logging into the “admin panel” of the router and slightly changing the wireless network settings. First: change b/g/n to b/g. Did it work? This means that the wireless module of your device does not support the 802.11n standard. It's okay, in most cases, this will not affect the speed of network access. If it doesn’t work, try manually specifying the wireless network channel there (usually “automatic”).
And one more unlikely, but possible option, which I had to deal with three times, and twice for the iPad tablet. The device also refused to see the access point, and this was solved by setting the United States region in the router instead of Russia.
Other problems
If the connection constantly breaks during operation, make sure that you have the latest firmware installed; if this is not the case, update it. Read the forums: perhaps other clients of your provider with the same router that you have already encountered such a problem and have solutions to this matter.
For some Internet providers, access to local resources, such as torrent trackers, game servers and others, requires setting up static routes in the router. If this is the case, then you will most likely find information on how to register them in the router on the forum of the company that provides you with Internet access.
