Por que meu adaptador de rede sem fio USB é desconectado a cada poucos segundos?

Eu não tenho experiência com drivers e outras coisas. Depois de instalar o Linux Mint 11 na minha máquina (fiz um dist-upgrade), tudo parecia ser ótimo - eu não precisava instalar nenhum driver. Depois de um tempo, percebi que minha conexão pararia depois de alguns minutos (isso mostra que estou conectado, mas não estou), então preciso me reconectar. Após alguns minutos, desconecta-se novamente.

Estou usando um adaptador sem fio USB da Alfa AWS036H. Eu acho que o driver que estou usando é o Realtek

Estes são alguns resultados de algumas coisas que as pessoas geralmente pedem. Nota: NÃO estou usando um laptop.

Eu resolvi esse problema instalando o driver RTL8187L e o carregando.

Eu usei este tutorial (é para RTL8187 e R8187): aqui
Esse tutorial é perfeito, mas ainda tenho problemas com o novo driver.

Eu tinha este um semelhante coisa acontecer ao meu Linksys wusb100v2 (driver rt2870sta de Ralink). Inicialmente, ele descartava os pacotes aleatoriamente e, mais tarde, começava a expirar enquanto aguardava uma concessão de DHCP; depois, ficava lá enquanto a porta USB registrava o registro do dispositivo alguns segundos depois ad infinitum.

Eu finalmente fiquei curioso e abri o estojo para descobrir que um dos diodos no PCB havia se fundido em um pequeno pedaço de solda. Eu tive que comprar um novo.

A garantia já estava expirada na minha, então eu não tive nenhum escrúpulo em abri-la, mas se a sua ainda for boa, eu aproveitaria e a substituiria.
