This is kind of off topic, but I have to give my two cents worth:
RT2500 = garbage;

Two Averatec laptops, equipped with built in RT2500 chipsets, were 
purchased at the same time by me and a friend.

I immediately wiped the disk and installed FreeBSD, my buddy isn't 
very technical and stuck with Windows XP.

The RT2500 aggravated the heck out of me.  The only way I could get a 
decent signal was to put the laptop two feet away from the wireless 
router.  This isn't a FreeBSD issue.  My buddy experienced the same 
weak and dropped signals running Windows XP. We both have WRT54G's as 

I wound up buying a Netgear pccard with the Atheros chipset, and it 
just works flawlessly.  I made my buddy do the same. Kind of pissed I 
had to shell out $50.00, but I'm not aggravated any more.
