Internet via radio conexão USB

[Andruntu]

Gente tenho internet via radio mas nao consigo configurá-la no UBUNTU. Vi vários posts aqui mas nenhum me ajudou.
Utilizei o comando pppoeconf mas nao deu certo.
Acho que a diferença dos usuários dos outros posts é que minha conexão da internet é via USB, não sei se já viram isso mas é assim que funciona. E tipo um pen-drive conectado ao cabo da antena.
No Windows tem um programa instalado que reconhece as redes chamado ZDWlan. No Ubuntu as redes já aparecem, mas preciso autenticar a conexão com usuário e senha. Como faço isso no UBUNTU......Abaixo meus comandos lspci e ifconfig
