Hello! In this article we will try to deal with a new, but already very popular problem, when, after updating to Windows 10, the Internet stops working via Wi-Fi, or via a network cable. I faced this problem myself. My laptop on Windows 10 did not react at all to the connection of the network cable.
Let's consider possible problems with the Internet that may arise after an update, or a clean installation of Windows 10. As practice shows, problems can be very different:
- Internet just disappears
- There is no Wireless adapter in Device Manager
- No wired LAN adapter
- Connection via Wi-Fi, or via cable "Limited"
- No Wi-Fi enable button.
And a number of other problems.
If you upgraded to Windows 10, your Internet stopped working, and you didn't really like the "ten", then you can roll back the system to Windows 7, or 8 (which was installed before the upgrade). You can do this within a month in the Start menu - Settings - Recovery. Well, if you like the new operating system, then you can try to fix the problems with the Internet connection. What we are going to do now.
And for starters, a general tip: for any internet problems, try disabling your antivirus. Disable protection temporarily to check if the problem is in it. Very often, it is the antivirus that is to blame. Many people advise to remove the antivirus altogether before updating.
Windows 10: Wi-Fi Issues After Update
Let's take a look at possible wireless network problems first.
1. If, after installing "tens", you cannot detect Wi-Fi on your laptop at all (stationary computer), the problem is most likely in the wireless adapter driver. In general, the problem with the drivers is the most popular problem.
If you cannot find the buttons to turn on the Wi-Fi network, you do not see the list of available networks, but in the settings, on the tab Airplane mode If there is an error "Could not find wireless devices on this computer", then most likely the Wireless LAN adapter is disabled, the driver is not installed on the Wireless LAN adapter, or the driver is installed, but it does not work correctly (not suitable for a new system).
I wrote about the solution to this problem in the article: How to enable Wi-Fi in Windows 10 when there is no Wi-Fi button and the error "Could not find wireless devices on this computer." As a rule, everything is solved by turning on the adapter, and even more often by installing or updating the wireless adapter driver.
The whole problem is that after the update, Windows 10 does not always install a stable, working driver on Wi-Fi. It all depends on your hardware. You can go to the device manager and see if there is a tab Network adapters, Wireless adapter (see article on the link above). It can be with a red cross, or not at all.
As a rule, this problem is solved by downloading and installing the driver from the website of your laptop manufacturer. Download the driver carefully. It is necessary that it was specifically for your model, and for Windows 10. Many manufacturers have not yet released drivers for the "dozen", so you can try to install the driver for Windows 8 (8.1). Again, it all depends on the hardware, the built-in wireless adapter.
If you have a stationary computer with a USB / PCI adapter, then you need to download the driver from the adapter manufacturer's website.
After the forced installation of the new driver, Wi-Fi should work.
2. "Connection limited" error and a yellow triangle with an exclamation mark next to the Wi-Fi icon.
Another popular problem that can be found not only after the update. Now I will not write about all possible solutions, but just give a link to a detailed article on solving the "Connection limited" problem in Windows 10.
Other Internet problems in Windows 10
1. When connected via a network cable from a router, or an Internet provider.
As I wrote at the beginning of this article, if Windows 10 does not react when connecting a network cable, then we update the drivers for the network card. And check if the adapter is enabled "Ethernet".
Here is an article to solve this problem: https://help-wifi.com/reshenie-problem-i-oshibok/ne-rabotaet-internet-v-windows-10-posle-podklyucheniya-setevogo-kabelya/
Well, if you observe the status "Limited" when connected by cable, then first of all you need to check if the checkbox opposite IP version 4 (TCP / IPv4) in the properties of the Ethernet adapter. We open Network Control Center, and choose Change adapter settings.
Next, right-click on the adapter"Ethernet"... And in a new window, check if the box next to "IP version 4 (TCP / IPv4)" is checked.
You can also select the IP version 4 (TCP / IPv4) item, click on the properties button, and check if automatic obtaining of IP and DNS addresses is set.
Make sure that there are no problems with the router or provider (for example, check the work on other devices), and then try to update the LAN adapter driver.
2. If after the update there is no connection via 3G / 4G modem.
In this case, the problem is most likely in the driver for your USB modem. You need to search, download and install a driver for your modem model, and for Windows 10. The only problem may be that your modem manufacturer has not yet released such a driver. The best way to look for a driver is on the website of the modem manufacturer, or on the website of the Internet provider.

Run Windows Network Diagnostics
Another method to try for any internet problems. This is the launch of Windows built-in diagnostics and fixes for possible network problems.
Right click on the internet connection icon, and select Troubleshooting.
The system will start looking for problems, and perhaps, if it finds something, it will offer you to fix them. Follow the instructions in the diagnostic window.
You may see the error "The network adapter has no valid IP settings" in the diagnostic results. I wrote about its solution in a separate article: https://help-wifi.com/reshenie-problem-i-oshibok/setevoj-adapter-ne-imeet-dopustimyx-parametrov-nastrojki-ip-windows-10-8-7 /
Update
In the comments, we wrote one way that can help solve the problem with access to the Internet in Windows 10. We need to register Google's DNS in the properties of our Internet connection.
If you have a cable connection, then open the "Ethernet" connection properties, and if over Wi-Fi, then "Wireless network". Select the item "IP version 4 (TCP / IPv4)", click the "Properties" button.
In the field "Preferred DNS server" we write 8.8.8.8. In the second field, you can also write 8.8.4.4.
Click "Ok" and restart your computer.
