Strangest Wireless Problem I've Ever Seen

I dug up my old Thinkpad R40 with Intel pro wireless 2100 mini network
adapter and updated it to XP SP3 from XP SP1.

I use a Linksys N router with my 2 other notebook PCs (WAP2 encryption) and
have no problem whatsoever.

I updated the Intel 2100 driver because the old driver didn't have the WAP2
feature. I successfully connected the Thinkpad to the router.

Now, here's the strangest part. The wireless connection stays well-connected
if I simply browse the Internet. However, the Thinkpad loses connection in
20-30 seconds after I start downloading a relatively big file. Then, the
Thinkpad re-establishes wireless connection.

I've tried everything I can think of: disabling AVG, windows firewall,
spy-bot. The Thinkpad had no trouble with wireless connection when I used
WEP in the past. What do you think is happening?

WPA2, not WAP2, if you don't mind.

The 2100 is quite outdated, and perhaps simply does not work well with WPA2
(though the new driver supports it)

Ummm... I have to disagree with you. WinXP SP3 does include WPA2.
Don't believe me? Read SP3 whitepaper yourself.

I doubt Intel PRO Wireless 2100 supports WPA2. If you insist on using 2100
adapter, lower your security to WPA and use a long alphanumeric password (40
characters or longer) that isn't found in any dictionary. WPA security with
a long password is just as hard to break.
