On my Ubuntu 20, everything was working fine when suddenly my wifi stopped and all configs were disappeared. At software center it was showing broadcom & legacy driver then I messed it up using lot of commands but nothing worked somehow and that was also removed. I don't know what to do next. I Googled lot but I found nothing related. Any help would be appreciated.
