This is a well-known issue with the 2200BG. Intel does some funky power management that causes issues with this card being able to maintain a steady connection to any AP that doesnt impliment some kind of complementary feature that tells the card to keep the transmission power up. Since almost every AP vendor out there except Intel does not apparently impliment this (Ive heard but Ive experienced the problem first hand with 3com, DLink, Linksys, and SMC). So the result is that you get flakey connections at wide open no encryption/authentication settings, and if you are trying to connect to, say, a WPA with TKIP and RADIUS authentication forget it. Compounding the issue is that there are also 3 or 4 different hardware revisions of the 2200BG, and the earliest ones have the worst problems.
You can somewhat ameliorate the issue by going to the advanced tab on the driver properties, scroll down to Power Management, uncheck Default and move the slider all the way over to Highest. Yes your battery life will be shorter but at least you will be able to use your WLAN card. You should also update to the latest driver, 188.8.131.52, but Intel does not have it posted on their site. You have to call or email and complain to get it from them. IBM evidently also has a version of the driver that corrects the issue, but its not as recent as the Intel driver. I have the driver if you want to email me for it. Even after installing this driver, I still had to disable Power Management for the 2200, but its rock solid with my DLink DI-624M and can finally associate with Linksys AP's and the 3com 8750's at my work.
Link to Intel's driver (might expire) - Includes ProSet util, might have to de-kludge the link if its wrapped, very long.https://secure.filesanywhere.com/xEL...C5%7E%9D%9D%A0
If its expired, just email Intel support, tell them you have a 220BG with conenction problems and want the 184.108.40.206 version or later of the driver. A day or two later they will respond with a link similar to the above.
