I am having the same issues with my Latitude 800. I have the identical wireless card "Intel PRO/Wireless 2200 (B/G) with the latest chipset, bios, and network card drivers downloaded and installed, and am dropping off the network periodically without warning. I'm calling support to see if they can resolve this issue.
An Update: well after failing to get any network drivers I had previously installed to be used without dropping a signal, i turned to hp supplied drivers and they seem to work.
Thats the specific url for the drivers, I tried the lastest released version on their site as well and I still had the drop problems, but the specific drivers that this link goes to should work... It doesn't install the prowireless client software, just the drivers, so it uses windows to maintain the connection, but it seems to work. If you find out anything else let me know.
Most frequent cause of dropped connection with a "good" signal is you're getting radio interference. Look for other other wireless access points conflicting, and also remember you can get disruption from all kinds of 2.4GHz equipment cordless phones, microwaves (ovens, and real microwave comms gear), bluetooth...
Try a few different channels on the wireless access point, this finally got my bad CRC packets down from >25% to <1% but its trial and error.
I had already eliminated the wireless interface problem because A: if i drop down to B on this card it works wonderfully, and B: I had been previously using a linksys pcmcia card with absolutely no problems, the problems started accuring when I started using this specific card, but like I said using the HP drivers seems to have fixed the problem... On another note, my brother has a phone that is 2.4ghz and it randomly picks a channel for each call, pretty obvious what is happenig when he answers the phone and my wireless completely drops out, only relief from that is there is a "chan" button on the phone which will manually change the channel, just can't fix the channel with the phone, but thats only a small issue.
I'm having the same problem with my c400 and I know it's the Intel card as I just recently purchased my 2 c400's and put the Intel 2200 cards in them and I was very happy to find your post seeing that you are having the same problem. I know that it is the Intel card that is causing the problem, because I can put my D-Link DWL-g630 in the pcmcia slot and it works flawlessly. I wish I could get the link that you posted from HP to work, but so far no luck.. I'll keep trying..
OK I got the HP site to come up and I downloaded the drivers, but how in the heck did you install them? I uninstalled the Intel provided drivers and then tried to install the ones from HP and can't get them to install.
To install the HP distributed drivers, download them from the link above, run the executable, it will extract the drivers to : C:\SWSetup\WLanDrvInstallIntel\Intel-2200-2915 in the device manager, right click on the network card and click upgrade, and select that locatin for the drivers, it will show both the 2200 and the 2915 in the driver list when installing, make sure you install the proper driver. It will also say that "microsoft does not believe this is the proper driver for this device blah blah blah..." just click on the option that says you don't care.

Measuring bad CRC packets... I'm using an el-cheapo pcmcia wireless card - Edimax 7108 cardbus, cost me about £15 here in UK (about $25 if you think in Federal Beer Vouchers). It uses the Ralink RT2500 chipset and comes with a simple utility including the connection stats and proper signal strength in numeric dBm instead of low/med/high idiot lights.
It's not a well known name, it doesn't make my coffee, but it seems to be reliable, connects to every access point I've tried it against, and at this price... if I break it or lose it, it's a consumable.

dbuk,
What did you use to measure your bad CRC packets?
