It is quite annoying in Linux that the name of a network interface is unpredictable. I added wireless support on my laptop. The wired interface changed from eth0to eth1and caused all sorts of problem.
The package ifrenamesolves the problem nicely.
apt-get install ifrename
Next add the the mac address of each network card in /etc/iftab:
wire mac 00:40:45:24:A0:DC wifi mac 00:0C:F1:09:2B:27
You'll need to reference you card as wire and wifi in
/etc/network/interfaces. Things will break when you change network
card, but that's a small price to pay for some sanity in network
interface names.
