The problem of Internet access in the presence of a seemingly active and working connection is one of the most common. It would seem that all the settings are correct, but the user complains anyway, saying that I canāt access the Internet. What is the reason for this, how to rectify the situation and restore access to the World Wide Web, read in the material below.
I canāt access the Internet. Writes: "Error 105"
In order to choose a tool to eliminate such failures and errors, you must first find out the reason for this behavior of the existing connection.
You should immediately pay attention to the fact that the two most common situations are:
- Internet connection is active, but sites do not open;
- There is a network connection, but no internet access.
Actually, in both cases, the problem is precisely with the connection, although at some point the system does not notify the user about this. As for the root cause, it can be in the connection settings on the computer, in the āgatheringā of the routerās parameters, and even from the side of the provider or server of the requested Internet resource.
First of all, you need to check whether the failure refers to only one computer terminal. If we consider wireless networks based on Wi-Fi, first try to connect to the desired Internet resource from another device (laptop, tablet or mobile phone). If the connection is established and the desired page opens, you will have to change the settings of the problem computer. If you canāt access the desired resource via an Internet connection from any device, or, even worse, there is no Internet access at all, you need to check the global settings. Note that the matter is not limited to the 105th error, and there can be quite a lot of similar messages in different variations from the browser or the system.
A network without Internet access: what does it mean, and how to deal with it?
In general, despite the fact that such situations can occur when establishing a connection with different types of connections, they are most typical for wireless networks. We will take them for consideration as an example, although the solutions proposed below work equally well in the case of a wired connection.
It is believed (and not without reason) that such situations are among the easiest to resolve. Here, at least, it is precisely known that the connection is for some reason broken.
If the system says āWithout access to the Internetā on the connection icon, the easiest solution is to disconnect from the existing network and reconnect via the menu, called by clicking on the icon in the system tray. If the problem is associated with short-term failures in the operating system itself (which is also possible), sometimes it is enough to simply reboot and see what the result will be after the restart.
Router issues
But let's assume that the described actions did not produce a result. Let's say a user on some forum asks for advice: āI canāt access the Internet. What is the reason?". What should he answer?
Often the problem of lack of access can be associated with a router (router). You never know, maybe the settings "flew" or there was still some kind of problem. In this case, most experts recommend performing a complete reboot of the device, but not by pressing the reset button on the rear panel while the router is running, but after completely disconnecting it for about 10-15 seconds and then turning it on. It is possible that after restarting the described problem will disappear (which, incidentally, happens quite often).
If the problem is in the spontaneous change of the router settings, after entering the deviceās web interface through any available browser, you need to check whether the signal distribution is turned on.
Proxy activation check
In various forums you can often find messages of such a plan: āI canāt access the Internet. The system asks to check the proxy settings. " Well, itās also possible to deal with such phenomena if you do not have to use a proxy server and configure its provider to access the Internet, all of this must be disabled.
You can perform such actions in the browser properties, where in the network settings section of the connections tab the parameters are automatically determined and the check box for proxy activation for local addresses is unchecked. This approach works just in case the connection is active, but the pages do not open in the browser.
Change browser and activate VPN
In some cases, when pages do not open during a working connection, it is advisable to change the Internet browser used. If you use, for example, Internet Explorer or Edge browsers that are built into Windows systems, try accessing the desired resource using some other browser, such as Chrome or Opera. In this case, it is completely optional to install them on your computer. To test access, any portable version is quite enough.
It is possible that pages can be blocked for visitors only because of their regional affiliation.
Alternatively, in the same "Opera" try turning on the VPN and try to access the desired resource again.
Reset Network Settings
But back to the situation when we have a network connection without access to the Internet. What to do in this case to restore access? You can completely reset the network settings with clearing the DNS cache. In general, a little distracting from the topic, it is worth noting that the problem of networks with lack of access to the World Wide Web is precisely inoperative DNS settings. To fix the problem, you should use the command line, running it with administrator privileges, and alternately execute the commands presented below:
- ipconfig / flushdns;
- ipconfig / registerdns;
- ipconfig / renew;
- ipconfig / release.
If the execution of these lines does not produce results (which is unlikely), two additional commands can be used as an additional tool:
- netsh interface reset all;
- netsh winsock reset.
In theory, after that, everything will return to normal, if only the problem was really associated with violations in the settings of the parameters initially set.
Change DNS addresses
Another option for resolving problems with network connections without access to the Internet is to set the DNS server address values āāyourself. However, you need to use free combinations for this, say, from Google (or Yandex).
To set the necessary parameters, go to the network connection properties (ncpa.cpl in the "Run" console) and go to the IPv4 protocol settings, where the combinations are entered from the bottom, for example, based on eights and fours (Google DNS). After saving the installed options, access will be restored. And this, by the way, is one of the most effective methods.
Problems with the hosts file
Finally, few ordinary users know that some Internet resources can be blocked in the settings of the hosts file, which Trojans like to change.
Changing the file you are looking for is not so simple. First of all, it must be opened in Notepad, which runs exclusively with administrator rights. The object to be opened is located in the etc folder located in the drivers directory, which is located in the System32 directory.
If you look at the contents of the file, all links to resources located in the text after two lines with the mention of localhost (127.0.0.1 and :: 1) are blocked. To fix the problem, simply delete everything below the two lines described and save the changes.
Virus Removal Tips
Now a few words about what tools to use for the most effective detection and neutralization of virus threats that can block access to the Internet. It makes no sense to rely on free full-time antiviruses. This, I think, and so it should be clear to everyone.
If you suspect that a virus has settled in the system, first do an in-depth scan with portable utilities. Among them, preference should be given to Dr. programs. Web CureIt! and KVRT. When starting such applications, you should immediately update the virus databases. No less effective are disk applications under the general name Rescue Disk, which can load their own interface before the start of the main operating system, detect and delete almost all threats known today, not only on the computerās hard drive, but also in RAM or even on removable media.
Brief summary
In general, if a user asks for advice about the fact that they say I canāt access the Internet, he should first find out the reason for the lack of access. But in most cases (in particular, with system notifications about the lack of an Internet connection), the problem is just DNS.
It goes without saying that with a working connection, the problem may be on the server itself or even on the part of the provider serving you. Such situations were not considered. Finally, if the tray displays the icon for lack of access on the icon, no matter how trite it sounds, check your balance. But what if the Internet access service is not paid, or has expired? This can also be.
And how to access the Internet in this case? No way, just pay the bill. So draw conclusions.
