No internet access in Windows 10: how to find the source of the problem

To get you back online quickly, you should systematically check for possible sources of error:

  • If you are using a local area network connection, the first thing you need to do is make sure the network connection is properly connected to your computer and router. Besides, the wire must not be damaged or broken. If you find it is damaged, you need to replace it as soon as possible.
  • If you want to connect your computer via Wi-Fi, make sure Wi-Fi is turned on on both your computer and your router. Yes, this is the most commonplace, but also the most common cause of communication problems.
  • If the computer cannot find the router via Wi-Fi, either the router is too far away, or the Wi-Fi is disabled. Make sure you are in an area with the network coverage.
  • Also, check that you are using the correct network key (Wi-Fi password).
  • In some cases, an antivirus system or firewall can block your internet connection. Disable both services briefly to see if this is the reason for the disconnection.
  • Disconnecting the router from the mains for about 10 seconds and restarting the computer can also help.

VPN interferes with Internet access

Unsupported VPN software could be the source of the problem:

  • Right-click on the Start button and select Command Prompt.
  • Enter the command “netcfg –sn” and confirm your action by pressing Enter.
  • You will receive a list of all network protocols, drivers, and services. Find the entry “DNI_DNE” here.
  • If you find it, enter the following command at the command line: “reg delete HKCR CLSID {988248f3-a1ad-49bf-9170-676cbbc36ba3} / va / f netcfg -v -u dni_dne”. Confirm your entry again with Enter.
  • If an error message appears after this, you must manually delete the key. Under Run, type regedit to open Registry Editor.
  • Go to the key “HKEY_CLASSES_ROOT CLSID {988248f3-a1ad-49bf-9170-676cbbc36ba3}” and delete it.
  • After completing the entire procedure, restart your computer.

Wi-Fi is connected, but there is no internet – what should I do?

If Windows 10 doesn’t have internet access despite having Wi-Fi-connected, try the following:

  • Make sure the IP configuration is correct for Network access. You can do this by going to the Connections tab in the control panel and checking if the DHCP server, DNS server, internal IP address, and gateway of the router are entered.
  • If this is not the case, open the Properties tab and click on Internet Protocol Version 4. Once in this section, click on “Properties” and check the box “Obtain an IP address automatically.”
  • Check your proxy settings: since traffic is routed through the proxy, the internet will not work if the settings are incorrect. To check them, go to the “Internet Connection” tab in the control panel and click “Connections.”
  • Open “LAN Settings.” In the “Proxy server” area, there should be no check box next to “Use a proxy server for local connections.” If there is one, remove it.

If your internet connection is not restored, contact your internet service provider. Perhaps the problem lies in a problem on his side.
