High wireless values on RF Counters in Cisco PI

[smashytech]

Hi,

Im troubleshooting a messy wifi enviroment. We're using 3602I all the way, on version 7.6x

Users are experiencing that the wifi is dropping, however the client numbers on the AP remains steady, however i've come by this statistics below:

I've asked local support to try and ping their default gateway when this happens, but i've yet to hear from him.

RF Counters

Tx Fragment Count 212784754 Multicast Tx Frame Count 8093620 Tx Failed Count 3149560 Retry Count 9521658 Multiple Retry Count 1787587 Frame Duplicate Count 0 RTS Success Count 22884959 RTS Failure Count 34587092 ACK Failure Count 4268994575 Rx Fragment Count 0 Multicast Rx Frame Count 0 FCS Error Count 23435678 Tx Frame Count 213284161 WEP Undecryptable Count 15738

We're using flex connect APs and the CAPWAPtunnel has been up as long as the AP have been up. However i feel that this statistics seems quite high? Correct me if I'm wrong.

Any ideas on what may cause this?
