I use an ibm thinkpad with a cisco wireless card and frequently issue "apm
-s" to put the machine to sleep. The weird thing is that sometimes when I
wake it up, the wireless card switches from its normal eth1 to eth0. eth0
is the onboard ethernet interface and has a static IP address assigned to
it.
When exhibiting this odd behaviour after waking the laptop up, an "ifup
eth1" does nothing. However, "ifup eth0" works fine. Sometimes I can even
put it back to sleep, and when I wake it up, the interfaces will be
switched again. Hah!
