Well, im trying to make mi wifi work on Ubuntu for first time.
I read in the forums that a lot of people have problems with this wifi realtek drivers and i am one of them too.
I found a quick and cool step by step but it starts with "Set Security boot DISABLED and type on terminal iwconfig.
I cant enable security boot, so its disable by default but when i type iwconfig it just says "no wireless extensions"
idk what to do anymore.
