Lately, I have been having an annoying problem with my Cisco 350 Access Point and PC-Card. Everytime, data is being transferred over the wireless connection, the speed drops down to 2Mbps and recovers to 11Mbps, when the data is no longer being sent.
This happens independently of the relative position of the devices, with the signal strength at 100% and Signal Quality at 75%.
A reinstallation of winXP did not improve the situation, neither did upgrading both devices to the newest firmware, or using Win2000 on a different computer.
I would be grateful for any pointers that would help me solve this problem.
Thanks for helping me. The client reports 21,418 PLCP CRC Errors and 14216 MAC CRC Errors, within 4,5 hours of up time and 17Mb Transmitted.
Does that qualify as "a lot"? The firmware on the AP is 12.03T. I've gone through all the channels, but without much luck. I have the feeling that around channels 6, there the fewest of the above CRC errors per minute.
