Windows update causing Internet connectivity issues
Whilst we await an official fix from Microsoft, there are several ways to resolve the problem and get yourself back online quickly.
Method 1 – Hard Reboot
First of all, try a hard reboot. Hold down the Shift key on your keyboard and simultaneously press Start and click the Power Button in the Start Menu. While still holding the Shift button select Shut Down. Continue holding the Shift button down until the PC has fully powered down, then reboot.
If this doesn’t work for you, try the second method:
Method 2 – Reset Networking Stack
Right click on the Start button (in the bottom left corner of your screen) and select “Command Prompt (Admin)”. Enter the following commands in the black window, exactly as written below:
netsh winsock reset catalog netsh int ipv4 reset reset.log
Now restart your computer and you should be up and running again.
