wireless and eth1 for ethernet)

AFAIK, this is really a kernel issue. The kernel assigns network device names in the order it encounters the devices, and from time to time (usually after an upgrade), it encounters them in a different order than usual.

The workaround I use is to configure /etc/modprobe.conf to make sure
that when one driver gets loaded (the one I want to be eth1), it first
loads the other driver (the one I want to be eth0):

alias eth1 orinoco_cs
alias eth0 e100
# Force eth0 to get loaded before orinoco_cs, to make sure
# the network devices get the right names
install orinoco_cs /sbin/modprobe -q eth0; /sbin/modprobe --ignore-install orinoco_cs

Hope this helps.

That's an interesting idea. I was going to suggest just deleting all network interfaces and devices in system-config-network and recreating them, letting the configurator detect and assign the devices by type.

If you've really screwed up the configuration, you may want to do the redetection anyway whether you force the load order or not.
