In this manual - in detail about what to do if the Internet stopped working after updating or installing Windows 10 and about the common causes of this. Equally, the ways are suitable for those users who use the final and insider assemblies of the system (the latter often encounter the challenge). A case will also be considered when the connection has become "limited without Internet access" with a yellow exclamation mark after updating Wi-Fi. Additionally: How to fix the error "Ethernet or Wi-Fi network adapter or Wi-Fi has no valid IP settings", an unidentified Windows 10 network.
Update: In the updated Windows 10, a quick way to reset all network parameters and Internet settings to the original state when problems with connections appeared - how to reset the Windows 10 network settings.
The manual is divided into two parts: the first lists more typical causes of the disappearance of the Internet connection after the update, and in the second - after installing and reinstalling the OS. However, methods from the second part can be suitable for cases of problems after the update.
The Internet does not work after upgrading to Windows 10 or installing updates in it.
You updated Windows 10 or installed the latest updates to the already installed ten and the Internet (on a wire or Wi-Fi) disappeared. Below in order are the steps to be taken in this case.
The first step is to check whether all the necessary protocols for the Internet are enabled in the connection properties. To do this, do the following.
- Press the Windows + R keys on the keyboard, enter NCPA.CPL and press ENTER.
- A list of connections will open, click on the one you use to exit the Internet, right-click and select "Properties".
- Note the list "The marked components are used by this connection". For normal operation, the Internet must be enabled at least, the IP version 4. But in general, the default is a complete list of protocols, which also provides support for the local home network, transformation of computer names to IP, etc.
- If you have important protocols turned out to be turned off (and this happens after the update), enable them and apply the connection settings.
Now check if Internet access appeared (provided that the component check showed that the protocols for some reason were really turned off).
Note: If multiple connections are used for wired Internet - on the local network + PPPoE (high-speed connection) or L2TP, PPTP (VPN connection), then check the protocols and for another connection.
If this option did not come up (i.e., the protocols are included), then the next prevalence is the reason that the Internet does not work after upgrading to Windows 10 - the installed antivirus or firewall.
That is, if you have been installed any third-party antivirus before upgrading, and you, without deleting it, updated to 10-ki, it can cause internet problems. Such problems were seen from ESET, BitDefender, Comodo (including firewall), Avast and Avg, but I think the list is not complete. And simply disabling protection, as a rule, does not solve the Internet problem.
The solution is to completely remove the antivirus or a firewall (it is better to use the official utilities of deletion from the developers sites, more details - how to completely remove the antivirus from the computer), restart the computer or laptop, check if the Internet works, and if it works, then install the desired You have antivirus to re-(and you can change the antivirus, see the best free antiviruses).
In addition to anti-virus software, a similar problem can be called previously installed third-party programs for VPN if you have something like that, try removing such a software from a computer, restart it and check the operation of the Internet.
If the problem arose with a Wi-Fi connection, and after updating Wi-Fi, it continues to connect, but always writes that the connection is limited and without accessing the Internet, first try the following:
- Go to the Device Manager through the right click on the start.
- In the "Network Adapters" section, find your Wi-Fi adapter, click on it right-click, select "Properties".
- On the "Power Management" tab, remove the "Allow shutdown of this device to save energy" and apply the settings.
According to the experience, this action most often turns out to be operational (provided that the situation with a limited connection via Wi-Fi originated after upgrading to Windows 10). If this does not help, try the ways from here: the Wi-Fi connection is limited or does not work in Windows 10. See also: Wi-Fi connection without Internet access.
If nothing of the above options helped correct the problem, I recommend also to read the article: the pages in the browser do not open, and Skype works (even if it does not connect you, in the specified instruction there are tips that can help restore Internet connection). Also useful may also be tips that are given further for the non-working Internet after installing the OS.
If the Internet stopped working after clean installation or reinstall Windows 10
If the Internet does not work immediately after installing Windows 10 to a computer or laptop, then with the most likely the problem is caused by the drivers of the network card or Wi-Fi adapter.
At the same time, some users mistakenly believe that if the device manager shows that "the device works fine", and when you try to update Windows driver, reports that they do not need to be updated, then it's not exactly the drivers. However, it is not.
The first thing to be concerned after installing the system with similar problems - download official drivers for the chipset, network card and Wi-Fi (if any). This follows from the manufacturer of the computer's motherboard (for PC) or from the manufacturer's laptop manufacturer, specifically for your model (and not use driver-pack or "universal" driver). At the same time, if there are no drivers for Windows 10 on the official site, you can download both Windows 8 or 7 in the same bit.
When they are installed, it is better to first remove those drivers that Windows 10 installed itself, for this:
- Go to the Device Manager (Right Click on Starting - "Device Manager").
- In the "Network Adapters" section, click on the desired adapter with the right mouse button and select "Properties".
- On the Driver tab, delete the available driver.
After that, run the driver file previously downloaded from the official site, it must be installed normally and, if the Internet problem was caused by this particular factor, everything should earn.
Another possible reason on which the Internet may not work immediately after reinstalling Windows - it requires some setting, creating a connection or changing the parameters of an existing connection, such information is almost always available on the provider's website, check (especially if you first installed OS and do not know whether the Internet is needed for your provider).
Additional Information

Another extensive instruction in case the Internet does not work on the cable - the Internet does not work on a computer via a cable or a router and an additional material in case there is no Internet only in applications from the Windows 10 and EDGE store, and there are other programs.
