If the Internet does not work, and there is no way to call a specialist urgently, you can try to adjust the settings yourself using our article.
Tip: before looking for methods to solve problems in the network and router settings, check the status of your account with the provider and the reliability of the network cable, in about half of the cases this solves the problem.
Firewall or antivirus?
Sometimes, Internet access can be blocked by the system's own protection agents, like a firewall or antivirus. Define ban Windows firewall 8 is quite simple - turn it off in the system settings and check the connection, if the network appears - the problem is detected.
If the ban comes from the antivirus, you need to disable the program directly or end the corresponding processes through the task manager.
Configuring Firewall in Windows OS
The main function of a firewall is to check data coming from the Internet and block those that cause concern. There are two modes "white" and "black" list. White - block everything except what is allowed, black - allow everything except what is forbidden. Even after full customization firewall remains the need to set permissions for new applications.
To find the firewall:
If you already have an antivirus installed, disable the firewall as shown in this picture.
Blocking outgoing connections
Firewall and sometimes antivirus can completely block all outgoing connections.
To block outgoing connections with a firewall in white filter mode, you need to:
- go to " Extra options» firewall;
- open the "Properties" window;
- put "outgoing connections" in the "block" mode in the private and public profile.
Application rules
There is a special list of programs that are allowed to exchange data with the Internet, and if the one you need is blocked, you just need to configure permissions for it in this list. In addition, you can set notifications so that if a new application is blocked, you have the choice to leave everything as it is and allow access to this program.
For example, you can block access to the Internet for Skype or Google Chrome, or vice versa, leave access only for a couple of specific work programs.

Service Rules
To configure access for services:
- go to advanced firewall settings;
- on the left, select incoming or outgoing rules;
- on the right, select the item "Create a rule";
- select "Custom" from the list;
- enter the name of the service or select it from the proposed list.
In new Windows versions, starting with Vista, it is possible to select a service from a list without manually entering the service name. If you do not have access to a computer in windows network xp or windows server, you need to configure the access policy service, then detailed description can be found in the system help.
Activate the reserved rule
To activate a reserved rule, you need to repeat steps 1-3 from the previous section, then:
Allow VPN connection
To set a special permission VPN connections, you need to repeat steps 1-3 again, then:
Antivirus settings
If problems arise, one of the best options is to go to the antivirus website or contact product support, they will tell you exactly correct settings programs.
Antivirus should not block working programs - like Google Chrome or Skype, but should check them during operation.
Safe antivirus settings should include:
Update
The antivirus update should be up-to-date, either with the release of new versions, or monthly automatically.
No network access in Windows 7
If, when connecting, you see “Unidentified network”, but all settings are in order, contact the provider first - this may be its internal error.
After reinstallation Windows settings Internet usually return to the original, so you need to install them again:
Windows protocol errors can be the cause of the problem, to fix this, you need to reset the protocol settings.
It's pretty simple:
- run command line with administrator rights;
- enter and activate the command netsh int ip reset resetlog.txt;
- restart laptop.
Is it a problem with the router or the laptop?
When you have problems connecting via WiFi, you need to determine what is the source of the problem. It can be a laptop, router or provider. If all devices connect to the router and work normally with the Internet - the reason is in the laptop, if vice versa, connect network cable to the laptop and the Internet will work - you need to do the router settings. When all else fails, contact your provider's technical support.
The reason is the laptop.
If the problem is in the laptop, but all of the above settings are in order, run a system diagnostic for viruses and device operation. Possible malfunctions network driver or even disruption of work directly network card, connector.
Might not match wifi password points, for example, due to incorrect layout or CapsLock.
The reason is the Wi-Fi router
The router, with incorrect settings, can distribute WiFi without access to the network. Read on to find out how to set up your router correctly.
One of the reasons for connecting without a network may be to protect the Wi-Fi network from unauthorized access by blocking by MAC address. You can find out how to fix this problem on the router manufacturer's website, or find the list of allowed or blocked addresses in the settings yourself and add/delete the address of your laptop.
You can view the MAC address of your laptop by entering the Ipconfig / all command at the command prompt.
Also, the router has speed limit settings for each client, so you can either allow the speed to the maximum or limit it to a couple of kbsec.
Problems with Internet speed can be a signal for help from the router itself - perhaps you have not removed the factory film from it, it is covered with something or overheats for other reasons. If you do not provide the device with normal ventilation, then it will not live long and is extremely inefficient.
Checking internet connection without a router
If you suspect the router is the problem, you need to connect the network cable to your laptop or computer to check. If the Internet does not work automatically, create a new cable connection, enter the login and password provided by the provider. You may need to enter additional settings protocols in adapter properties.
Internet connection setup
To check if the IPv4 settings of the computer match those declared by the provider, you need to do the following:
- go to Network and Sharing Management;
- then to the Change adapter settings tab;
- in context menu connections, open Status;
- there click the Details button;
- check the IPv4 address and gateway, they must match those provided by the provider during registration.
Setting up a connection through a router occurs through the web interface of the device. The router sometimes comes with a settings disk, but you can do without it. For initial setup, it is best to connect the router directly to the laptop, and then with the Internet cable, connecting to the mains is done last.
- go to the web interface. To do this, open the browser and enter the IP address that is in the device documentation or on the sticker, right on the case.
It can be:
- 192.168.0.1
- 192.168.1.1
- 192.168.2.1
- enter the login and password to enter, they are also indicated in the documentation. This is usually admin-admin;
- in the Wireless menu we find the SSID item and enter the name of your future network;
- further, in the Security section of the same menu, create a network password, and in the Encryption item, select the most reliable WPA2-PSK;
- in the WAN connection section, choose the one provided by your ISP:
- do not forget to save the settings after each item.
If you don’t have enough time to wait for a specialist, you don’t want to spend money, you feel like a confident PC user, then using various instructions and recommendations, you can try to set up an Internet connection yourself. It will most likely take two to three times more time and energy than going to the master, but it will give a useful experience in the future.
In this age of new technologies, an antivirus for a computer can be compared to a virus vaccine for a person. If your antivirus does not work well, then most likely the PC will not live long. But it also happens that after installing the antivirus, you cannot access the Internet. This situation often occurs at work. antivirus Avast.
Avast is blocking the internet
Users may have encountered a situation where Avast blocks access to the Internet. It does not allow you to open any page in any browser. Avast Antivirus is blocking all network connections.
This situation can be caused by many reasons. Therefore, each of them will have to fix the problem, respectively.
Important! Most often, blocking occurs on a PC with Windows XP.
Looking for a way out
You can do like most users and just with. You can say goodbye to Avast at any time, so let's first figure out how to solve the problem and leave the antivirus (read about removing Avast antivirus).
First of all, you need to understand two things - why Avast blocks all sites and why Avast blocks the Internet. If the program blocks only one site, then it is probably really infected with a virus (you can read how to add a site to Avast exceptions).
But if when you launch all browsers you get a notification about the blocking of malicious screens, then you should proceed differently:
After you do everything according to the instructions, the problem with accessing the Internet will be fixed. Now you can solve the problem "Why is Avast blocking the browser?"
It happens differently
In cases where even these steps did not help fix the problem, it suggests that your computer did catch a virus. In this case, it is better to show it to a specialist and not puzzle over how to fix the situation. Why? Because if you are not an expert, you can make it even worse (for example, delete important system files). Therefore, do not immediately believe everything that you find on the global network.
Be attentive to notifications on the computer screen, listen to advice.
I hope this information was useful to you. All good luck!
It often happens that the antivirus blocks sites that are quite reliable, for example, in contact or classmates. Everyone can do this: Kaspersky, Nod (eset), Avast (avast), Avira, Avg and others. Why is this happening and how to fix it.
If the antivirus mistakenly blocks sites, then you may not be mistaken. The fact is that in contact or classmates, where you want to enter, in fact, they may turn out to be dummy.
Almost the same address (one letter changed) and the same content, but they were created by scammers to steal passwords.
These sites in contact and classmates (not only) are almost indistinguishable from real ones. , nodes, avast, avg know about them - so they block them to protect you from stealing passwords or viruses.
If you are completely confident in the reliability of blocked sites, then this can be fixed without disabling antiviruses. Everyone has such opportunities. Since I now have a node installed, I will show how this is done using its example.
In order for the antivirus to erroneously no longer block sites that you think are trustworthy, you need to manual mode add to its database. To do this, by clicking on it at the bottom of the tray, launch it and click settings. See picture:
Now look at the picture and add sites (in contact, classmates) to the database that the antivirus should not block.
You can add as many as you want, the main thing is not to be mistaken in their reliability.
You can do the same with other antiviruses that, in your opinion, mistakenly block sites. Everyone has these mechanisms. I showed Eset as an example, since I have it in this moment installed. In this way, you simply add the site to the exceptions.
You can also add files (programs) to exclusions in the same way so that the antivirus does not block them, only the settings are slightly different (you need to select other options). Of course antivirus, but it’s better not to do that and never send SMS.
You can drive a phone number, and sometimes you need to, but you can’t send SMS in any case. The phone number is entered so that you can later recover the password. Such functions have classmates, vkontakte, emails, skype, banking sites and the like.
There is nothing wrong with this, but on the contrary, it is even better, because then no one can change your password without your knowledge. Sorry, I digressed a little from the main topic of why the antivirus blocks trusted sites.
However, there is nothing more to write about. Antivirus programs block what, in their opinion, is very dangerous for you, if they are in doubt, they simply warn you, although it often happens that developers quite consciously make sure that their antiviruses block reliable sites and programs.
They have their own reasons (they protect their interests), then manually add sites and files to exceptions, using the method described above, or simply disable them for a while, although disabling does not always help. Good luck!
Hello dear friends!
It often happens that when you change your antivirus program, you are faced with the problem of complete inability to visit previously accessible sites. Why does this happen? Is antivirus really a virus? Of course not, because everything is much simpler here: the antivirus program blocks websites because it cares about the safety of your computer! Yes, and this problem is solved very simply: you need to add previously visited sites (to which the antivirus program does not let you now) to the exceptions.
Especially often such a "monster" as ESET Nod32 blocks sites, so it is on its example that I will show the solution to the problem. So!
First, immediately after installing and running the program, the antivirus blocks sites that it considers potentially dangerous. Naturally, not all sites are classified as such, but what is an antivirus program in fact? This is a reinsurer who operates according to the rule "it's better to get around than step on a rake." And this is absolutely true, comrades! Agree: it is much better when your computer is free of viruses than when you have a global virus problem, such as an MBR Trojan?! (From the author: if you don’t already know, then MBR viruses can be picked up precisely from links to sites! And the saddest thing is that you cannot remove the MBR virus, since it is written in the very first line boot sector systems! In short, the only way out is complete reinstallation systems, naturally with the complete loss of all data. how do you like this prospect, huh? Therefore, there is no need to "chait" your defender: he does his job correctly).
Secondly, it is very easy to unblock the entrance to web pages. Here is a detailed unlock algorithm. First, we enter the advanced settings with ESET Nod32 antivirus. We expand the branch of necessary items: Protection against viruses and spyware- Internet access protection - HTTP, HTTPS - Address management - Add. Now it remains to enter the address of the desired site in the exceptions. For example, the address you enter may look like this: *site.com*, where instead of site you enter the desired domain of the site you are accessing. Be sure to put "asterisks" at the beginning and at the end of the address (example - *site.com*). Click "OK" and "OK" again. Everything. But for the sake of consolidating the material, here is an example for you: you need to get to the site http://webportal.com.ua/. You do this: F5 - Protection against viruses and spyware - Internet access protection - HTTP, HTTPS - Address management - Add. In "Add" write the address *webportal.com.ua*, press "OK" and again "OK" and that's it: access is granted. A similar algorithm is used in other antivirus programs. Good luck!
