Not really. Sometimes eth0 and wlan0, or just eth0...

module load confusion maybe

Okay, I maybe able to help here. I use two different modules for my wireless card. Kinda the
same scenario as yours, not exactly, but close enough I think. Here's my gig, let's say I want to use
/etc/pcmcia/hostap_cs.conf (hostap modules) instead of /etc/pcmcia/wlan-ng.conf (wlanng module).

state is up and running with wlanng module.

ifconfig wlan0 down
rmmod prism2_cs p80211
cardmgr eject (this is important here, maybe not there)
then I physically remove the card
mv /etc/pcmcia/wlan-ng.conf /etc/pcmcia/wlan-ng.conf.save (keeps pcmcia_cs from loading it out of confusion)
mv /etc/pcmcia/hostap_cs.conf.save /etc/pcmcia/hostap_cs.conf (I previously added the save to use the wlanng module)
service pcmcia restart (important!)
insert card
presto, hostap module is used with no conflicts what so ever.

My ip,netmask,gw,and ... is stored in /etc/pcmcia/network.opts, this never changes here though. It sounds like module/pcmcia_cs
confusion. I'm not sure if wireless uses the same /etc/pcmcia/network.opts as the wired card does, but I reckon so. If you desire
separate configs for /etc/pcmcia/network.opts, then use the .save method from above. And of course, when the method is solid,
just script it or add it as a function to .bashrc.

Hope it helps,
eddie
