I'm using Ubuntu 20.04 and I can't connect to a specific wifi network. I have the password and I can connect to it with success in the same laptop with Windows 10 but in ubuntu it stays connecting for a long time then connection failed ,I have tried most of the solutions on the internet and nothing works. I can connect to my mobile hotspot easily. The problem in connecting to my home router only.

  • Worked for me, tried a lot of things from here https://askubuntu.com/q/960691/496677 and https://askubuntu.com/a/622493/496677, didn't know how suddenly I got this issue but I'm glad I wasn't the only one facing this issue. – Hemangi Gokhale Apr 06 '23 at 08:30
  • Finally for me this solution worked. I just changed the specific band (selected B/G 2.4 GHz instead of automatic, as it was the case of my router), and I left the channel as "automatic", and it worked anyway. – marcor92 Dec 03 '23 at 18:25
