Caro Tanderblue, reanimando este tópico, consultei alguns foruns no oráculo e consegui achar alguma coisa.
o site da Ralink já disponibilizou um driver atualizado. Agora eu to numa VM, mas momentos atras eu consegui conectar meu Kubuntu à internet por alguns instantes. eu upei o mudulo rt2800usb e desconectei da VM. ai quando eu fui no knetworkmanager percebi que o sinal do ponto de acesso que eu uso estava com o sinal mais alto. configurei a conexão e ela foi autenticada. só teve um problema, usando o comando ping ele dava 100% de recebimento, mas o firefox não retratava isso, no maximo consegui abrir a pagina inicial do google. quando eu reiniciei o computador não consegui conectar mais.
abaixo os resultados dos comandos que eu usei qndo estava funcionando (pingava mas so entrava na pagina inicial do google):
