Ola, pessoal

gostaria da ajuda de voces num probleminha que esta dando dores de cabeça

minha net é de 1mega, quando conecto a rede ele navega a uns cento e poucos kbps (o normal)
apos algum tempo cai pra menos da metade, as paginas demoram muito a abrir...
tambem acontece problema de cair a conexao caso algo se posicione entre o netbook e o router

meu netbook eh um positivo mobo black 3060
uso xubuntu 10.4
ja usei o ubuntu netbook mas nao me adaptei e tambem tinha esse mesmo problema
outros computadores da rede nao tem o mesmo problema

ja tentei instalar outro driver seguindo a explicacao dos seguintes sites:
