[ubuntu-it] Dopo aggiornamento non va più wifi

[pacmo a tiscalinet.it]

3crusb10075 è il dispositvo wifi usb che usavo sotto edge.
Ho aggiornato ad edgy e subito mi ha dato 200 righe di questo errore :
firmware_helper ..... main error loading
'/lib/firmware/bcm43xx_microcodes.fw for device ....with driver 'bcm43xx'
Ho copiato i driver bcm43xx da 2.6.15 a 2.6.17 e l'errore non è più
comparso ... in compenso.

Le spie dell'aggeggio sono spente. A volte trova la rete per un attimo
