  • First, he updated the wifi driver but it didn’t fix the network issues. He was still getting “unidentified network”, “limited access” and sometimes “no internet access” errors at all.
  • Then he tried to change TCP/IPv4 settings which sometimes worked, but the “limited access” and “unidentified network” kept coming back.
  • Lastly, he ended up the clean format to his system that fixed the problem once and for all.
