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.

Faced the same issue. Just changed the specific band (selected B/G 2.4 GHz instead of automatic, and I left the channel as "automatic", and it worked.
