I have a Cisco 4400 series controller with 15 LWAPs configured.
I've noticed that some Windows CE wireless clients (proprietary hand helds) generate around 1200-1500
Data Retries per 500-900k bytes sent.
Doesn't happen to all of them, but it seems to be specific to 2-3 APs.
What could cause the Data Retries?
Interference seems to be pretty low in the area, and I haven't gotten any alarms on the controller, but I have users complaining to "waiting for data" when using the handhelds.
