If the network is troubled and functions such as searching for other computers, access to the Internet or sharing folders no longer work, you should use the Windows analysis tools as a first step.
Windows standard tools help with network problems
You can find this in the “Settings” under “Update and security -› Troubleshooting – ›Additional troubleshooting”. The three wizards “Internet Connections”, “Shared Folders” and “Network Adapters” are of interest for the network area. Then mark these entries one after the other and click on “Run troubleshooting”. Windows will now perform an analysis and in many cases it can solve the problem.
You can use the netsh command in the command prompt to reset the Windows network configuration back to the default settings.
In the event that this does not work, you can reset the network to the default settings in a second step. Caution: If you have made an individual network configuration for the hardware and software of your PC or changed settings in the firewall, they will then have disappeared. For the reset you need a console with administrative rights: Type cmd into the search field of the task bar, click on the hit “Command Prompt” with the right mouse button and select “Run as administrator”. Next, enter the command netsh int ip reset and confirm with “Enter”. Now let Windows restart. Open a command prompt with admin rights again and this time enter the command netsh winsock reset. Then do another restart.
In the third run, write the command netshadvfirewall reset in the command prompt opened with admin rights. Let your computer reboot one last time, and then check that everything is working again.
