Drivers from the modem on the PC may be missing.

No network set up on the PC?

It was like that from one day to the next. The network is set up as far as I know and yesterday the DNS was set and checked whether the name resolution works with the settings, and it has that too.

Then simply reset your network in the Windows settings under "Network and Internet".

The network is set up as far as I know? Delete and recreate!

Great thank you. That was the answer to the riddle.

That set up with the network worked.

You're welcome!
