It was probably after pushing a couple of gigs over it (didn't feel like 
freeing up a port in the upstairs wired hub) overnight. Not how I normally 
use these cards.

Is the AP not on the same subnet? If it is, I would recommend bringing down 
eth0 (ifdown eth0) while testing wlan0. I'm assuming that eth0 is also 
currently your default route.

My understanding is that it's more like a bridge. It tries to make wireless 
nodes appear as if they are on the local subnet that the AP is physically 
attached to.

If you don't see lbl's (little blinky lights), you might do an 
/etc/init.d/pcmcia restart. Sometimes I've had to do that, even with the card 
in during bootup. But, that was also with a previous Linksys and old-ish 
pcmcia drivers.

Also make sure that there are no wireless drivers enabled in the kernel.

Hope you get it working.
