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.
