Olá!
Instalei Ubuntu neste computador mas estou com um sério problema. Minha placa de rede sem fio, uma RTL8187SE, da Realtek, é reconhecida, mas o sinal das redes é extremamente instável, a conexão é péssima -- quando não cai. Já tentei instalar o driver do Windows pelo ndiswrapper, mas sem sucesso.
No Uíndous a conexão é perfeita, usando os últimos drivers, que são os mesmos que tentei usar pelo ndiswrapper.
Abaixo algumas saídas:

Se forem pedir por mais algum comando, tentem especificar bem o que procuram saber, já que estou sem internet no Linux... E ficar trafegando entre Uíndous-Linux é fogo.
Agradeço!
