Problema scheda ethernet Broadcom

[The Doctor]

Sul PC dell'ufficio uso Ubuntu 12.04.4 LTS. Con gli ultimi kernel la scheda di rete Broadcom BCM57780 non funziona più correttamente. Per aprire una qualunque pagina internet ci mette un secolo, ma anche se accedo via SSH ai vari file server / mailserver che gestisco.

Sulle informazioni di connessione mi dice driver utilizzato tg3. Probabilmente è quello che rompe le scatole. Ora ho messo una 3COM 10/100 ma vorrei utilizzare la Broadcom che è Gigabit. Che faccio? Non ho voglia di mettermi a compilare un kernel vanilla
