Tarjeta Ethernet integrada VIA no se conecta a la red

Hola  nuevamente.

Quiero revivir in pc antiguo y se me ocurrió instalarle Mandriva One 2010.2, así que junté unas piezas y lo eché  a andar.

Todo se instaló correctamente, pero la tarjeta de red no se conecta por dhcp ni a un modem Arris que tengo y tampoco a un router Fujitel que también tengo. Si lo hago manual se conecta, pero no puedo acceder a nada, ni Internet y ni al dispositivo.

Me metí al buscador, y en unos hilos no solucionan el problema.

Los datos de la tarjeta son

Lo que me parece extraño es que se ha creado una tarjeta virtual eth0:9, pero no se si eso afecte el funcionamiento de la tarjeta.

Muchas gracias por la ayuda
