Trådløst virker ikke Emnet er løst

[Rinus]

Hej på min nye medion som jeg endelig har fået til at dual boot, virker wifi ikke i ubuntu 13.04. Jeg kan skrive kodeordet til netværket og det ser ud til at det så er tilsluttet men der er ingen forbindelse eller en meget lille hastighed. Hvad kan dette skyldes?

Hvilken driver snakker vi om?

ud fra hvad du skriver går jeg ud fra du kan komme på internet

hvor langt sidder du fra routeren?

Ja internet virker ok i win 8

Der ser ikke ud, som om der er noget trådløst!!!!

Ved søgning med

broadcast=yes driver=rtl8192cu

kommer der en del foreslag, og umiddelbart, kan jeg ikke se hvad der vil virke for dig, men tjek dem ud.

Har heller ikke mere tid lige nu

[Rinus]

Har prøvet nogle af dem, men synes ikke det hjælper, men hvad med denne driver: Det Linux Kernel 2.6.18~2.6.38 and Kernel 3.0.8? Der er en tar, gz fil hvordan installeres den?

[Rinus]

Nu tror jeg det virker, men ved ikke helt hvorfor
