Routers and access points with Wi-Fi are an integral attribute of the home and mobile internet for 10 years now. Once upon a time speed Wi-Fi work-the network can be greatly reduced, and sometimes the wireless connection disappears completely and for a long time.
The main reasons for disruption of the Wi-Fi network
Problems with wireless Internet access may be due to for various reasons: router failures, incorrect computer or smartphone settings, interference from nearby equipment, etc. Viruses and even the actions of hackers can disrupt operation. In all cases, you need to identify the cause of the malfunction and try to eliminate it - first yourself, and if that doesn’t work, then turn to professional computer specialists.
The Wi-Fi network is visible to devices, but they do not connect to it
There may be several reasons why there may be no connection to a Wi-Fi network.
Wi-Fi network is not visible to devices
There are several reasons why the Wi-Fi network is not visible from a gadget or PC.
Wi-Fi on PC or tablet does not work after reinstalling Windows
There are several reasons - from hardware to software.
Video: WI-Fi does not work after Windows 10 update
Laptop or tablet is connected to Wi-Fi, but there is no Internet
The reasons are due to the fact that the router does not have Internet access.
There is Internet via Wi-Fi, but it turns off on its own
There may also be several reasons.
- Inadequate Internet connection quality. If the provider has an unreliable communication channel or, in the battle for first place in the list of the most popular operators, has gone too far with the number of clients, the speed of individual users will be very low, the connection will often reconnect due to equipment overload, and incoming traffic will freeze. Previously, cellular providers suffered from this - on initial stages development of the 2G/3G/4G coverage area, demand in the conditions of a collapse in the price of 1 MB of traffic far outstripped the construction and launch of new network facilities.
- Freeze random access memory router (data buffer overload). Restarting it will help.
- The device has overheated - any modern technology has protection against overheating of microcircuits. Both the CPU/RAM of the router or access point, as well as any of its microcontrollers that process data incoming/outgoing via LAN or Wi-Fi, can overheat. It is advisable to turn off the router for at least a few minutes.
If the 3G/4G signal is poor and the Internet speed is high, the 4G modem used with the router may also overheat. Users of Android smartphones and tablets (Yota subscribers), who distributed up to 40 GB every day via Wi-Fi (in the 2000s, these were Nokia and Motorola mobile phones connected via cable or Bluetooth), talk about cases when the device got hot like a kettle and turned off every hour or two of downloading/distributing torrents on the PC. The same thing happens with routers.
Wi-Fi does not work due to firmware glitches and viruses
No matter how simple, friendly and secure the firmware (firmware) of the router is, the router itself is not protected from malfunctions and viruses. Virus technologies disrupted the operation of Apple, Android and Symbian gadgets. Virus code penetrated card machines, ATMs and access control systems at protected sites with the Internet, disabled the firmware in USB modems. Routers are also not insured - neither purely wireless from Beeline or Yota, nor home ZyXEL and TP-Link, nor Cisco access points, nor purely cable equipment used in facilities where any wireless element is prohibited by security rules.
Software failures can occur either due to inept flashing (through ignorance or accident, the power is reset during a firmware update in the router’s flash memory), or wear and tear of the flash memory chip itself (it’s impossible to even enter the router settings - underloading of the web pages interface in the browser).
Virus activity is expressed in reprogramming the router settings: changing the IP DNS to the values of the malicious server, substituting primitive passwords or turning off Wi-Fi security settings, switching wired protocols and operating modes cellular networks etc. To fix this, do the following.
Sometimes the virus changes the firmware file just before it is downloaded to the router. The solution is to remove viruses from the PC, using all means including formatting the drive (of course, transferring valuable data to other media before doing this) and downloading the official firmware version again from the manufacturer’s website.
Slow Internet speed via Wi-Fi
The reasons are related to both the quality of network access and Wi-Fi communication parameters.
The last point requires clarification. The fact is that the Wi-Fi speed is switched by the router and the gadget automatically. Even if you forcefully turn on the maximum (802.11n or 150 Mbit/s), then if you go into the next room, you may lose your connection to the Internet - incoming and outgoing traffic will freeze, websites will stop opening and messengers will stop working, even simple ones like ICQ , since the lower level speed (802.11g, or 54 Mbit/s) will not be enabled.
Different Wi-Fi types networks support different data transfer rates
Check the auto speed selection in the router settings.
Advice for experimenters: without highly directional antennas and amplifiers, do not be located far from the router.

Other Wi-Fi errors and their solutions
The full list of errors in Wi-Fi operation is not limited to failures of the Wi-Fi repeater alone or problems on the provider’s side.
Network cable is not connected
The provider's network cable connected to the WAN socket may not be connected either to the router itself or to the entrance terminal. The reasons are as follows:
- damaged cable wires;
- broken RJ-45 connector retainer holding the cable in the LAN socket;
- power outage (the terminal has no autonomous power supply);
- malfunction of the LAN interface in the terminal and/or router (burnout of network equipment throughout the entire area from electrical interference, an accidentally dropped network wire, static discharge when touching materials or a lightning strike on external cables);
- a faulty LAN network card in a PC or laptop (it happens that the adapter in Windows is detected as a working device, but the connection cannot be recognized);
- viruses on PCs that overload Windows performance (displaying incorrect connection status or connecting with a delay of minutes or hours).
The connection is already in use or not configured
Error 651 indicates that the modem or dedicated one is already in use or has not been configured.
If the router is not configured or is already in use by other processes, error 651 is displayed
Your connection needs to be removed and reconfigured. The instructions are suitable for Windows 7/8/10 - working with the network connection setup wizard in the latest versions has not been enriched with anything special.
After clicking the “Connect” button, a connection to the Internet will be established. If the problem persists, contact your provider's support. In the worst case scenario, reinstalling Windows helps.
Infinitely obtaining an IP address from the router
Without receiving at least a temporary IP address from the DHCP IP address numbering range of the router, the gadget or PC will not be able to access the network. And this is typical not only for Wi-Fi connections - the assignment of an IP to a computer or mobile device was established when TCP/IP was created.
If the device freezes at the stage of obtaining an IP address, you need to check the router settings
You need to check the router's IP settings.
Checking Wi-Fi settings
Do the following.
You may need to restart the router again.
Checking services and connections in Windows
Ensure that all services, addresses, and protocols critical to the network are enabled correctly. The following services are responsible for Windows networking capabilities:
- DHCP client;
- DNS client;
- WLAN auto-configuration service;
- web client;
- IP auxiliary service;
- routing and remote access;
- server.
Do the following.
The connection of the router or cable modem to the network is broken
ADSL modems, popular in the 2000s, are being actively replaced by ONT modems (optical network terminal) - these devices support Internet speeds of up to 1 Gbit/s (using GPON technology), which differs from the throughput of an ADSL modem by 10 times. Already, Rostelecom and local providers provide Internet speeds of about 35–100 Mbit/s.
Blame the decline Wi-Fi speed There may be not only a reduced external speed at the cheapest available tariff, but also damage to the optical cables in the section ONT-modem - home rack-terminal - the nearest provider node. The LAN cable between the router and ONT modem may also be damaged.
The router in access point mode acts as a LAN/Wi-Fi distributor
The user can diagnose the entire subnet of the router (the router itself and its external cable). In case of damage to cables and equipment, including the ONT modem, telephone, IPTV set-top box and cables in the entrance, you should use the help of technical specialists from the same Rostelecom. This is also explained by the fact that if a twisted pair cable can be restored/replaced independently, then the subscriber simply may not have the tools to splice damaged fiber-optic lines.

Solving problems with Wi-Fi at home and at work is not particularly difficult. In many cases, the user will figure it out on his own. The help of a specialist is required only in cases where problems arise on the provider’s side.
Views: 869 Available on Android devices such a problem when, after connecting to wireless network, the Wi-Fi icon is gray, not blue, and the Internet does not work in Google Play, and other programs. Sites usually open, but there are also cases when there is a connection, but the Internet does not workThere is a problem on Android devices when, after connecting to a wireless network, the Wi-Fi icon is gray instead of blue and the Internet does not work in Google Play and other programs. Sites usually open, but there are also cases when there is a connection, but the Internet does not work at all, even in the browser. Moreover, on Android, not everyone immediately notices this gray Wi-Fi network icon; most likely everyone faces a problem when they simply I can’t log into Google Play Market, the error “No connection” or “Check your connection and try again” appears.
And in the browser, when you try to open a website, the error “The clock is behind” (NET::ERR_CERT_DATE_INVALID) may appear.
As for the Wi-Fi connection icon itself, on Android devices without any proprietary skins, it can actually be gray instead of blue. It looks something like this:
But basically, the wireless network connection icon does not change. Even if such a problem appears. I checked it on Lenovo and Meizu M2 Note. It was not possible to access Google Play, YouTube, etc., but the Wi-Fi connection icon itself did not change in any way. Is it always gray there?
This means that if, after connecting to Wi-Fi, you encounter a problem where there is no access to the Internet in Google Play Market, YouTub and other programs, while the sites are in the browser on your Android tablet or smartphone open, then see the tips from this article. If the Internet does not work at all, but there is a connection, then see the article: Why does the Internet via Wi-Fi not work on an Android tablet or smartphone?
Gray Wi-Fi icon on Android and Google Play not working. How to fix?
I myself have encountered this problem several times already, and I have seen a lot of information on the Internet on this topic. So now let’s look at the most popular reasons and solutions that can cause such problems with Wi-Fi on Android.
First of all, I advise you to try method number 6! As it turned out, installing Dr.Web antivirus immediately solves the problem with the gray Wi-Fi icon.
1 Time. Date of. Timezone. These parameters need to be checked first. If the date or time on your phone or tablet is set incorrectly, Wi-Fi will be gray and Play Market will not work. This is verified, we change the date on the phone, and the Market cannot access the Internet.
Therefore, go to the settings of your device, to the tab where the time is set, and check if the settings there are correct. You can check the box next to the item for automatically setting the date and time, or, conversely, uncheck it and set everything manually. Also, be sure to check your time zone settings.
If you had incorrect parameters there, then after setting everything should work.
2 Freedom. If you are familiar with an application such as Freedom, or LuckyPatcher, you have it installed, or you installed it and uninstalled it, then you need to open Freedom (if necessary, install it again), wait a few minutes, and click on the button Stop.
After this, you can delete the application. The Wi-Fi icon should turn blue and everything should work.
3 Possibly a virus. Although I do not recognize the different antiviruses out there, mobile devices, but in such a situation, you can try installing some kind of free antivirus (download and run the apk file), and check your device.
4 Another option, which I will not consider in detail, is editing the hosts file. To do this, you can use an application like Ghost Commander. This file is located at system/etc/hosts. There you need to delete everything except the line 127.0.0.1 localhost.
In fact, this procedure is not very simple. And if you are not very good at this, then it is better not to edit anything. But if you know what Root rights are, and they are obtained on your device, then you can try.
5 There are many programs that, for example, block ads, etc. Remember, maybe you have recently installed similar programs. The Play Market may have stopped working due to the installation of these programs. If you installed something before this problem appeared, then it is better to remove these programs.
A sudden Internet shutdown is always unpleasant, and even more so in cases where problems with the Rostelecom router interfere with work closely related to connecting to the network, communicating with loved ones, watching movies online or playing a game session.
Why doesn't Wi-Fi work on the Rostelecom router?
There are several reasons for Rostelecom router malfunctions:
- problems on the provider side;
- router reset or incorrect configuration;
- hardware problems:
- line break.
The most common problem due to which a router cannot provide Internet access to various devices is a problem on the provider’s side associated with technical work or failure of server equipment located in local branches of the company.
The answer to the question: “Why doesn’t Wi-Fi work on the Rostelecom router?” There is a restriction of access to the network due to resetting the router settings, which can sometimes occur due to a sudden shutdown of the power supply to the device’s power supply or voltage surges.
The latter can lead to the failure of network equipment at the hardware level, which is not designed for voltages significantly exceeding 220 V.
If the light on the router does not light up, the problem may lie, in addition to problems with the provider’s equipment, in a malfunction of the Internet line from Rostelecom itself, which was physically damaged.
The Rostelecom router does not work due to problems with the server, what should I do?
To solve sudden problems connecting your Rostelecom router to the Internet due to the fault of the provider, you will need to contact the company operator using the 24-hour telephone number. Most likely, the technical center already knows about the problems and will be able to suggest an approximate time for their elimination. If the operator does not know information about problems associated with restricting Internet access, thanks to your call, he will be able to notify technicians. Specialists will find out the reasons and fix the breakdown, due to which the red light on the Rostelecom router is on, indicating a lack of connection.
Due to a reset, the Rostelecom Internet light on the router does not light up
To solve the problem of resetting parameters associated with power outages or power surges, it is necessary to reconfigure the equipment. Also, if problems arise for other reasons, you can set the default values personally by pressing the corresponding button on the back panel of the device or using the “Factory settings” item in the network equipment software.
If the Rostelecom Internet light on the router does not light up, but a Wi-Fi connection is available for all devices in limited network access mode, as indicated by a yellow triangle on the tray icon, you only need to enter the WAN parameters. In the case where the access point is not visible to the receivers at all, before this you will also need to configure the Wi-Fi itself.
Optimal equipment
Since the company provides a wide list of supported equipment, its setup will vary. Among the optimal models for connecting to the Internet, the provider identifies three routers:
- D-Link DIR 620;
- NetGear JNR 3210-1NNRUS;
- Upvel UR-315 BN.
WAN parameters
For example, the setup will be performed on D-Link DIR 620 network equipment. To get to the necessary parameters, you will first need to go to the router’s control menu.
To do this, by opening your browser, you need to enter the IP address of the equipment, which should be indicated in the instructions that come as standard. In the case of the DIR line, by default it has the value 192.168.0.1.
After logging in to the specified address, a form for entering your login and password will appear on the screen. In case of a complete reset of settings due to problems with the Rostelecom router, the fields must be filled in with admin and admin data, respectively.
After confirming the login, the user will be taken to the main D-Link equipment settings page. In the first item on the top left, called “Network”, the click’n’connect option will be available.
Using it, you can automatically obtain WAN parameters for a successful connection.
If this does not allow you to establish Internet access, you will need to resort to manual data entry. To do this, the user must go to the “Advanced settings” item, then “Network” and select the “WAN” sub-item.
By clicking on the active connection, a menu will open with fields in which you will need to enter the parameters specified on the company’s website or in the contract.
Do not forget to confirm and save the settings using the item with the image of a miniature light bulb, which notifies you when any action is required. You also need to remember that all settings will become active only after the equipment is rebooted.
If all actions on the Rostelecom router are performed correctly, the place of the burning red indicator will be replaced by a green one, indicating a correct connection with the provider.
WIFI connection settings
If the Internet icon on the Rostelecom router does not light up, this may mean full reset equipment parameters. In cases of connecting via Wi-FI, to configure them, in addition to entering the WAN values, you will also need to add wireless connection options.
Having entered the main page of the equipment menu, as indicated in the previous paragraph, you must select the second option from the top “Wi-Fi”.
will be present here step-by-step setup with system prompts. If you want to adjust the options in more detail, you need to go to “Advanced settings” in the lower horizontal menu, and then select “Basic settings” in the “Wi-Fi” item.
You will also need to install “Security Settings” by going to them from the previous window. After this, wireless Internet access will open, as evidenced by active indicators on the Rostelecom router.
What to do if your Rostelecom router is broken?
If the Rostelecom router stops working at the hardware level due to a voltage drop in the network, it will require a complete or partial (power supply or other burnt-out elements) replacement.
If the router cannot be configured by the user or does not turn on at all, you will need to contact the Rostelecom operator and create a request to call a specialist. After this, you will need to be present at home at the agreed time in order to provide access to the equipment for the technician, who may be able to fix the problem on the spot. In the case where the router was purchased from the provider company itself, it is possible to completely replace it with a working version. If a router connected to Rostelecom breaks down, but the equipment was purchased elsewhere, it will need to be repaired at the service center specified in the warranty card.
Is your Rostelecom router not working well?
Unstable operation of the equipment can be justified by the low quality of the router itself or its mechanical damage, as well as long distances or the number of obstacles in the signal path when using a Wi-Fi connection. In the first case, if the Rostelecom router does not work well, you should contact the provider’s support or the service center specified in the warranty card. In the second, you will need to use an additional access point configured in signal repeater mode, or special equipment.
conclusions
To the question: “Why doesn’t Wi-Fi work on the Rostelecom router?” There are several answers that will help identify hardware failure. If the software fails, thanks to the advanced prompts in the interface, you can easily configure the settings yourself. In case of hardware malfunctions, repairs will require warranty service or complete replacement of network equipment. How do you deal with router problems, use the services of a technician or personally configure the necessary parameters and, armed with a soldering iron, replace faulty elements?
Question from a user
Good afternoon.
Tell me what can be done - a yellow exclamation mark often appears on my laptop, indicating Wi-Fi without access to the Internet.
After a while it disappears, but constantly waiting for the network gets boring. I'm thinking of buying a cable to connect the laptop to the router directly (but then there will be no mobility) ...
Alexandra.
Good afternoon everyone.
The described problem with accessing the Internet via Wi-Fi is not that uncommon (I think that most Wi-Fi users We have encountered it more than once, and will encounter it again...). It occurs for many reasons, and I will analyze the most basic of them in this article (so to speak, I will give recommendations for restoring the network). So...
How to restore Internet access via Wi-Fi
The appearance of the error is shown in the screenshot below - a yellow exclamation mark lights up in the tray on the Wi-Fi icon; if you move the mouse pointer over it, you will see a characteristic message. Also, users often find out that something is wrong with the network when they try to open some web page - and instead see a message in the browser stating that the resource is unavailable (and this happens with all sites).
An example of an error: when you hover over the Wi-Fi icon, Windows reports that the connection is without Internet access...
Now about the decision...
Try rebooting your router and laptop
Oh... For many problems with your computer, it is recommended to restart it. And this time is no exception either (this error often occurs after the computer wakes up from sleep mode (hibernation). The fact is that after waking up from hibernation, Windows “thinks” that it is working with the old IP address, but the router has already given it a new one - and in As a result of this lack of agreement, connection problems are observed) ...
To reboot the router, you can use a special button on the device’s case, or simply disconnect its power supply from the network for a while.
I note that in case of many connection problems, such a forced reboot helps to quickly restore network functionality...
Important!
By the way, I highly recommend checking whether there is Internet on other devices using this Wi-Fi network- on a tablet, phone, etc. This will help you understand whether the problem is in the laptop (with Windows), or a problem with the router or provider.
Diagnose problems
Windows (at least 10) has very smart network diagnostics, which many people underestimate. Meanwhile, by running it, you can correct the lion's share of errors, and at least roughly know “where to dig”...
And so, right-click on the Wi-Fi connection icon and select (see screenshot below).
Next, the wizard will start: it will automatically check all the parameters, correct errors, restart the adapter (if necessary), and at the end of its work it will give you a message: that everything is in order and I have fixed the network, or indicate some kind of problem.
For example, in my case, the diagnostic result is “The DNS server is not responding.” This error occurs most often when there are problems with your Internet provider, or there is a communication channel break. For example, if you cut the network cable at the entrance (or simply remove the Internet cable from your router), you will see the same error...
Remark!
The article will tell you what to do if DNS servers do not respond (Internet failure and sites do not open) -
Check what's wrong with yours network cable Everything is fine
This advice follows from the previous point. First, take a look at the router itself: if everything is in order with it, one way or another, the LEDs on it should be lit and blinking (try disconnecting the Internet cable from the router, and then connecting it again - the number of lit/blinking LEDs should change, provided that everything is in order with the network cable) .
In addition, check the Internet cable from your PC to the entrance area. It is not at all uncommon for the cable to be chewed by pets or local “ghouls” to cut the cable in the entrance.
Is there a problem with your Internet provider?
Many users are in no hurry to call the provider, meanwhile, at the other end they can very quickly tell you whether everything is in order (which means you can quickly figure out whether it’s worth continuing to look for problems at home).
By the way, problems on the provider’s side are not that uncommon. You can find out about major interruptions on the provider's forums (or official websites. By the way, in these cases it is difficult to reach him by phone - they usually hang up).
Also, the provider may change the settings, forgetting to notify you (or you ignored the notification).
Try registering DNS Google or Yandex. Check your settings network connection.
Often, when the Internet is not available due to a failure of the DNS servers (in this case, most often, applications such as Skype, torrents, etc. work, but the pages do not open in the browser).
In this case, try to write DNS servers from Google or Yandex. Their stability will be higher than the DNS of many providers in our country, which means access to the Internet will be more stable...
To register DNS, you need to open the properties of the wireless connection. I'll look at it in order...
First you need to open a list of all network connections on your PC. To do this you need:
- press Win+R;
- enter ncpa.cpl ;
- press Enter.
How to view network connections in Windows 7/8/10
By the way, you may have more than one connection (as in my case), but several (you need to select the wireless option, if the English name is "Wireless...") .
After that, open properties "IP version 4 (TCP/IPv4)" . See screenshot below.
Next, you need to move one slider to the “Obtain an IP address automatically” mode (check this network connection setting!); the other one, related to DNS, set to the “Use the following addresses of DNS servers” mode - and register DNS from Google 8.8.8.8 and 8.8.4.4 (or from Yandex 77.88.8.8). See the screenshot below.
Save the settings and check the network functionality.
Check your router settings
Wi-Fi without an Internet connection often occurs due to a faulty router settings. Or, alternatively, your Internet service provider may have changed the settings required to access the network. For example, not long ago I was faced with the fact that my provider changed the login for accessing the Internet via the PPPoE protocol (the sad thing is that no one notified about this... Therefore, in the previous steps, I recommended asking the provider if everything is okay...) .
In general, setting up a router is a separate and big topic. Therefore, in this step I will provide a couple of links to my articles on this topic. I recommend checking it out.
How to connect and configure a new one Wi-Fi router do it yourself - instructions with pictures -
How to enter the router settings, and what to do if the settings do not open -
Test your network without antivirus or firewall
Well, the last thing I recommend is to temporarily disable your antivirus and firewall. This, of course, happens infrequently, but still, it happens that for security reasons and care for the user, they block the network (Especially, the Norton IS antivirus used to sin with this when setting the maximum level of protection. Apparently, they restricted the user from everything where it was hypothetically possible to pick up an infected file).
Most modern antiviruses can be disabled via their tray icon. For example, with Avast antivirus - this is done simply: just select the item "Manage Avast Screens" - and then specify the time for which the antivirus will be disabled. Everything is simple and fast...
To disable the firewall built into Windows, first go to control Panel . Next you need to open the section " System and safety" , then “Windows Defender Firewall” (see screenshot below).
Then click on the menu on the left "Turn the firewall on or off...".
Set all sliders to mode and save the settings.
After checking and Wi-Fi settings connections, and antivirus and firewall are recommended to be turned on (and adjust them accordingly if they were causing Wi-Fi instability. For example, you can reduce the security level they provide from maximum to medium) .
Additions on the topic are welcome (constructive criticism too).
