Please include the broadcom 5700 drivers in the next version of the live cd. I am forced to use the 1.4 version of the live cd as all of the computers I work with contain the broadcom 5700 adapter. And I am far too lazy to create my own custom live cd. Thanks.
I have a similar adapter on my Mainboard (it's the Gigabit lan, right?) Try to load the tg3 (TIGON3-support in kernel).
The bcm5700 driver was an addon hack, which is less reliable and less tested than the tg3 driver. Please use the tg3 driver, as it is the proper driver for your card. Thanks
