A PC without an internet connection is pretty much useless these days, and if you are having problems getting connected to a network and can’t get onto the Internet, don’t panic. There are few basic things you need to check before we actually troubleshot. Make sure you have a working internet, maybe try it with some other device, and secondly make sure your PC is properly connected over cable or connected to the router over WiFi. If that’s working fine, its time to check out our guide on how to fix the Media State Media disconnected error message on Windows 10.
Once you have reset the TCP/IP stack and Windows Sockets API entries, reboot your machine for the changes to take effect.
Is your Network Adapter Disabled?
If you have disabled the network adapters on your PC, you will need to re-enable it as well.
Go to Settings > Network and Internet > Select Ethernet > Change adapter options > Right click on the adapter, and enable it.
Check WiFi Properties
This is rare, but if WiFi Sharing has caused issues, you need to go to Network Connections > Right click WiFi > Properties > Sharing tab > Select the first one and press OK.
Go to Device Manager > Network Adapters, and click on the down arrow and it should reveal both the Ethernet adapter and your wifi adapter. Check if any of them have a red x on them? Right click on the one which has a red X and to choose Properties. Then click on the Driver tab to see which driver version it currently has. See if you can uninstall the driver, and reboot to let Windows find the driver for you. You can also download the driver from OEM website and update the driver.
