Problemas na placa de rede wifi

[math10]

Olá pessoal, estou com um problema de conexão wifi.

Conecto com o roteador e depois de um tempo a internet cai, no windows não acontecia isso por isso acho que seja problema de driver.
Já pesquisei em vários tópicos, entre eles:

http://ubuntuforum-br.org/index.php/topic,107957.0.html
http://askubuntu.com/questions/139632/wireless-card-realtek-rtl8723ae-bt-is-not-recognized
http://ubuntuforum-br.org/index.php/topic,107947.0.html

Já tentei instalar até outras versões do kernel, mas não consegui, o sistema nem inicia e tenho que voltar versão que instalei o sistema 3.8.0-32-generic

Utilizo o Ubuntu 12.04 e já tentei instalar o 13.04 e ocorreu o mesmo problema. (64 bits)

Nenhum dos drivers que consegui na internet para essa placa wifi não compilaram.
Erro ao complicar drivers baixados na internet:

A conexão a cabo funciona perfeitamente e quando eu conecto o cabo direto no notebook sem o roteador também funciona normal.
Quando eu conecto a wifi desse roteador com o celular também funciona normal e sempre utilizei esse roteador normalmente.
