Wilson,

Vi no seu log a saida de erro na Senha, e uma dizendo que você usa WPA-PSK.

Já tive problemas semelhantes ao seu, de conectar e desconectar quando eu
usava o Ubuntu 10.04, e no caso eu solucionei (na epóca) alterando a senha
da Rede a segurança para WEP (é mais vuneravel, mas Resolveu).

Já peguei casos de senha Wireless como essa: Tr4ce#!R0ut3*+ (Sim, Um
palavrão) e aconteceia que os caracteres "coringas" faziam dar pau nos
scripts de autenticação. A solução? Fiz um teste mudando a senha para
"VoceSabe" e ficou 3 Meses sem cair a rede, até que sugeri não usar mais
caracteres loucos. rsrsrs

Eu não consegui achar outro erro no teu log, fora esses que citei. Se o
pessoal da Lista achar outros é bem vindo. Mas fica minha dica em trocar a
senha da rede como testes.

Abs
