Reset network devices

No matter what network-related problem you are having, restarting network devices such as modems or wifi routers is the first thing that technicians advise you.

First, open the RUN window using the Windows + R key combination > type cmd

Once the DOS window appears, type the command 'ipconfig /release' and press Enter to release the IP addresses for all connected network adapters.

After the renew command is executed, the computer will assign a new IP address to your laptop. Now try to connect to the network again to see if you can access the Internet.
