I'm using XP SP2 (an "upgrade" from my former SP1.
A few month ago, I got a wireless G+ MIMO card by Trendware. After
installing it, ipconfig/all refused to show it as a connection. It
showed my LAN connections just fine, just no wireless. I checked the
hardware device manager and, much to my surprise, the card showed it
was working properly and correctly installed. Similarly, it showed up
just fine in the network connections. However, since there was no
ipconfig profile, there was also no IP address.

I chalked all this up to a fualty card and kicked myself for not going
with a more 'reputable' brand.

Fast forward to now. I borrowed my friend's perfectly good Belken
Wireless G card (7000 v5xxx)that works terrifically in his XP SP2 box.
Much to my surprise, I got the same results as I did with my trendware
card . . . no IP address, and no data from ipconfig. No amounts of
refresh and renew would change the status.

Has anybody encountered this problem before? Any ideas on what could
be wrong?
