I have just bought a dlink wna-2330 card pcmcia laptop wifi 
adapter. I was able to connect it to one linksys  (WRT54G) 
router with WAP2. However I am having very little luck with 
connecting it to another linksys router (WRT54GL) even without 
any encryption.

I am able to connect to the second router WRT54GL with a 
different card (I don't prefere this card because it only 
supports WEP) so, I believe the problem lies more in the d-link adapter rather
than the router itself

The router is newly bought from a respectable store so it 
shouldn't have any defects
from what I could gather it looks like that the dlink card 
associates with the AP and very soon de-associates. Sometimes it 
stays connected long enough to get a DHCP IP and send out some 
pings, but sometimes it doesn't even get a chance to receive a 
DHCP IP.

I'd like to figure out what's causing this problem and possibly fix it.

I've been watching the info from i{w,f}config and dmesg
I'm wondering if there is any other place I can look at to figure out what's going wrong
