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.

  2. Hmm, I’ve been using the 2200BG in my laptop for more than a year now and I haven’t experienced the problem you’re describing.

    I did have some issues with it when using the PRO/Set software that Intel provides to manage wireless networks. I then uninstalled it and downloaded the standalone drivers from IBM’s site and I just use XP’s wireless configuration options now. Works flawlessly. Just thought I’d let you know. Did you try it without Intel’s software?

  3. I have experienced the same problems on three different computers, including the HP Tablet I’m using now. When I started researching this I found several forums where a number of users are complaining about the exact same problems. Getting rid of the ProSet s/w doesn’t make any difference to me. The difference is definitely the new h/w.

  4. Even if you don’t have issues with your WiFi with this chipset, it might be worth a look to upgrade your drivers & software. My Toshiba M205 Tablet (purchased on 12/31/04) had drivers for the chipset dated 1/4/2004. The drivers were a full major and a few minor versions behind. I don’t have a “g” network yet, but I decided to upgrade the drivers. The new software includes functionality I didn’t have before, most notably: support for LEAP encryption, which is used extensively on Cisco-powered WiFi networks. I don’t see any difference just yet in terms of performance, but at least I have new functionality.
    BTW: Barb’s new HP DV4170 has the same chipset, however it has fairly recent drivers and software. We’ll see what happens when we get our “g” router in the near future.

  5. From the last post you made about this, I was able to get a good driver. It seems like there are many different hardware versions of Intels wireless board, and everytime they make a new rev of software, a previous hardware version fails.

    In your last post, after following that link, and another link, to the actual form, a user posted a beta version from Intel which was not available on Intel’s website yet. That version has worked great for me. It is about how it should work, enough so, that I will not upgrade to any later version. My problem is, the card is integrated inside the computer, and there is no other option to expand it (no PCMCIA slots.)

    I found the best way to test this card is to transfer a large file (>100 MB) to another computer on the network. If the card is not working, the transmition speed will crawl.

  6. I have a M205 just like Kevin Tofel and was getting really poor reception (when I could get any at all) from my G network (my neighbors B came in fine though). I don’t know why I never thought of upgrading my driver before, but after doing so today, my G reception has been fabulous! Thanks guys.

  7. Great post JK…did you see any info in your research on the Thinkpad a/b/g cardbus option for the x41 tablet pc, vs. the standard intel 2200bg that it otherwise comes with?

    thanks.

  8. I have an LE1600 and I have the self-same problems with 802.11/g.

    I have updated the drivers, installed the Intel software, uninstalled it etc etc. I have also tried switching the ‘polling’ off (most routers don’t support it) so the card is always running at full power. None of this works properly.

    This looks like one of those odd problems that will suddenly ‘go away’ when Intel finally discovers what is wrong…..

  9. I’ve replaced the mini-pci wi-fi card in other notebooks in the past. What is a good replacement for the 2200BG? And does Intel OEM for other manufacturers cards?

  10. I had same problems. PSP (power save polling) was the problem.
