Hoje
Eu instalei o 12.04 & amp; meu wifi parou de funcionar. Sem fio é detectado como RT2790 & amp; mostre a rede disponível mas não conecte a nenhuma rede sem fio (tentado fixado & inseguro) para alguma razão estranha.
aqui estão meus registros de depuração:

Agora, eu também estou executando o Ubuntu 10.10 nesta mesma máquina, pois meu wireless é detectado como o chipset RaLink RT2860 & amp; funciona perfeitamente). Eu posso me conectar à internet. aqui está a saída do lspci do Ubuntu 10.10

Interessante notar aqui é:
a mesma placa é detectada como dois chipsets diferentes ( RT2790 vs RT2860 )
a placa sem fio em questão aqui é:
Adaptador PCI Express sem fio PCE-N10 da Asus . E eu acho chipset neste cartão é RT2860 (não RT2790), me corrija se eu estiver errado. Eu ainda suspeito que esta detecção errada no Ubuntu 12.04 é a razão pela qual ele não conecta / trabalha.
Então,
Por favor, deixe-me saber se a minha suspeita está correta? Se sim, então o que eu preciso fazer para corrigir essa bagunça & amp; obter o meu cartão wireless trabalhando no Ubuntu 12.04?
