Onboard LAN

The notebook comes equiped with a Broadcom Corporation BCM4401-B0 100Base-TX card which is fully supported by the OpenSource "b44" driver.

In order to smoothly switch between WLAN and LAN in the same network, we apply a little trick. Normally the LAN card would get a different IP assigned (via DHCP) then the WLAN card due to different MACs. The DHCP server actually thinks it is talking to two different PCs.

This can cause all kind of breakage from halted ftp / www / BT transfers, to frozen NFS shares.

The following code configures my LAN card to use the same MAC address as my WLAN card:

iface eth0 inet dhcp
	pre-up ifconfig eth0 hw ether FF:EE:DD:CC:BB:AA
