We are having problems with our RF scanners that use 340 DOS drivers. They get disconnected from the HOST 3 or 4 times a day. We have 350 AP's for our wirless backbone. We also have laptops (running win2k)using 340 and 350 client cards and we never see any problems with those. We also notice large ping times to the clients that use the 340 dos drivers (400ms). Has anyone seen this problem? Or have any idea how to fix it? We have run sniffers and noticed a reset flag being sent prior to the disconnects. But we can't explain why this happens. Any thoughts or ideas would be appreciated.
