Intel ProSet 2200BG problems

Many notebook computers and Tablet PCs are currently shipping with the Intel ProSet wireless chipset that is designed to work closely with the Pentium M and provide good power management features to help conserve battery life for these mobile devices.  The Intel ProSet 2200BG is the chipset that is currently shipping in many such devices and there are many users reporting problems making and maintaining wireless connections with this chipset.  I have used three different devices that contained the 2200BG and I have had a lot of problems maintaining connections to 802.11g networks.  The 2200BG supports both 802.11b & g networks and in my experience the 2200BG works fine with "b" networks but has a lot of problems working with "g" connections.  The problems I have experienced were so pronounced on all three computers that working with the faster "g" networks was impractical, as my device would drop the connection after just a few minutes.

The Intel 2200BG is the chipset in my HP tc1100 Tablet PC and I have experienced nothing but problems with it from day one.  I have two WiFi networks in my house, one a "g" and the other a "b" and I have been unable to use the faster one at all.  When I am running around the city and encounter a "g" network I am in trouble as I cannot work with it reliably.   Rob Bushway reported problems with the 2200BG in his Motion LE1600 and when he installed the latest drivers from Intel and set the Intel power management to maximum performance his problems were greatly curtailed and he is no longer complaining about it.  Unfortunately for me this solution didn’t improve things at all on the tc1100 and I have been stuck until today.  I received a replacment W500 WLAN card from HP this morning that does not contain the Intel chipset and my problems with "g" networks was immediately corrected.  This W500 card supports a/b/g networks but since I only use b & g my only goal was to clear up the problems working with "g" networks.  I have been using it all day with my faster WiFi network and it has performed flawlessly, and the maximum range is greatly increased as well.  I do not know who makes this card for HP but I heartily recommend it to any tc1100 users experiencing WiFi connection difficulties.
