Computer: Acer Ultrabook Aspire M
Network Card: Qualcomm Atheros AR5BWB222

I can't connect to the internet because of this problem, please help me fix it.

Answer 1

This kind of message?
In the device manager, delete all network devices that you find there :)
Then open cmd and write:

netsh int ip reset
netsh interface tcp reset
netsh winsock reset

Next, update the configuration in the manager or, better, reboot . Reinstalling the device. Update to the latest driver version.

Answer 2

About ipconfig / all - read on the Internet, performed, did not help.

And it shouldn't have helped. This command is used for diagnostics. Run it and show what it outputs.
