Trådlöst nätverk slutade fungera

Postat: 26 apr 2016, 08:13

Hej
Sitter nu på ubuntu 16.04 uppdatering som gjordes i fredags.
Men idag kom det någon ny kernel uppdatering som jag installerade men efter omstarten slutade trådlösa nätverkskortet fungera, fast det finns med i nätverkslistan. Det står bara att det är utanför intervallet i nätverksinställningarna.
När jag provar och kör en wifi-adapter via usb så kan jag ansluta till trådlösa nätverket men ej från det inbyggda.

Vad gör jag nu för att få igång det interna nätverkskortet igen?

Nu har jag kört 2 kommandon här som kanske hjälper till lite ytterligare.
