Ubuntu nu vede WIFI!

Buna ziua. Am nevoie de ajutor referitor la nerecunoasterea WIFi de catre Ubuntu 18.04.4 LTS. Am un laptop vechi si am trecut de la Ubuntu 16  (pe care nu aveam probleme cu internetul/wifi) la acest nou Ubuntu. A trebuit sa reinstalez totul deoarece am reinstalat si Windows 10 (descarcat de pe microsoft) dar nelicentiat. Se poate sa fie o problema de la Windows (ca nu este cu licenta)? Am incercta tot felul de variante gasite pe net dar nu au functionat. Din pacate nu mai retin ce am facut (despre una am totusi ceva indicii deoarece am creat un folder in home, backport-iwlwifi).
Multumesc pentru ajutor iar daca trebuie sa dau si alte informatii va rog sa ma intrebati.

Re: Ubuntu nu vede WIFI!

Ciudat, vad ca modulul b43 pentru BCM4312 e incarcat.
Posibil sa-i lipseasca ceva totusi. Incearca sa dezactivezi si sa activezi din nou driverul din "Additional Drivers"
