Internet a Rádio com Placa PCI

[defabio]

Boa Noite.

Por favor me ajudem, ainda não consegui acessar o ubuntu 9.04 com minha internet a Rádio, o gerenciador de rede consegue enxergar a rede, grava o IP(DHCP), grava o dns mas o sinal é muito fraco fica oscilando com 1% até 10 % e não consegui navagar ainda, abaixo estão os procedimentos q fiz até agora:
