Sin acceso a internet desde linux por modem

Sab Abr 5 10:06:07 CLT 2008

Holas.

Desde que me cambie de residencia, me he quedado sin acceso a internet
desde mi portatil, pues todavia no me han instalado el dsl en casa,
asi que me toca acceder por conmutada, pero desde win, porque ubuntu
no me conecta. No entiendo que puede estar sucediendo, pues
aparentemente fue detectado sin problemas el modem:

esta es la info que lspci reporta de mi maquina, donde aparece el
modem detectado aparentemente sin problemas:

Sinceramente no se que buscar. Segun lo que logro entender de los
logs, el problema no es el modem, sino la calidad de la linea
telefonica o problemas con el ISP. Pero si me conecto desde win,
trabaja sin problemas.

Que me recomiendan para resolver esto?

gracias por su ayuda
