Olá a todos,

Tenho o Windows XP sp3 e instalei em outra partição o Ubuntu 9.04, tenho internet via Rádio o sinal está em 96%, mas no Ubuntu o sinal é muito fraco já instalei o driver (.inf) como ndiswripper, e mesmo assim o sinal ainda é fraco e não navega na net, meu sinal é por DHCP(172.16.254.85) e no Ubuntu tbm pega este endereço, vou postar abaixo:

Nao sei se precisa do driver de windows com ndiswripper.
experimente com o gerenciador de rede wicd, ou com MADwifi.
