Where to begin...we have a Cisco 1100 Aironet AP running about 25 clients in a auto service center. The clients keep losing signal to the AP, almost like some pulled the power plug on the 1100. The problem seems most persistent when the clients are left idle for minutes, but it also happens mid-process as well. Here are some of the things I've done:
-replaced old 1100 with brand new 1100 and configured from scratch...
-added power injector and plugged into a UPS...
-changed port on switch for AP
-moved clients as close as possible to AP
-deleted profiles on clients and re-created them
-deleted SSID on 1100 and re-created it
-turned off power management features for wi-fi cards on clients
-changed the IP address of the AP twice(in case of possible conflict)
-removed 2nd 1100 AP on different network in the same building
-turned off hibernation, system standby or any power manangement feature in XP
all the clients have random wi-fi cards, ranging from belkin, linksys, intel pro-set, dell 1390. The intels seem to be the worst... when I have windows manage the wireless settings on the intel cards, it seems a little better. they also have random wireless management software on the clients, ranging from XP, dell, intel... The only thing that all clients have in common is XP, but some are home edition and some are Pro.
sometimes all the clients drop at the same time, other times just the intel cards drop at the same time. I have to reboot the AP and the client and then its fine for a few hours.
I am wits end with this issue, I would run CAT5 or 6 but the ceiling is like 30 feet high and the runs would be well over 300 feet...
One of the employees noticed that when a car is put on a lift and raised near him, his wireless signal drops and then comes back...
the association page on the AP looks odd to me, why are there repeaters, 4500-radio's, unknowns, etc... there should only be windows XP clients with hostnames, correct?
