WAP321 - high ping response times

[mukka]

Hi all,

We are facing a issue with the WAP321.

Our wireless clients are facing communication issues  We can see a high response times during the ping tests.

LAN clients are working fine. 

the Signal level is excellent -30 dBM
the Noise level has a variation between -84dBm and -89dBm, but the SNR is good.

We have four WAP31 with the same behavior.

We have about 20 users per ap 
We tryed let a client per ap, but we faced the same behavior

What  could cause this behavior ?

We have the same issue with a WAP551 and a WAP561. Response time is incredibly slow, with n average response time of 400ms (between 100ms and 1200ms!!)

They are up to date with the last 1.1.0.4 firmware.

We have tried :

- Disable Bonjour
- Set a static channel per radio
- Use WPA2 purely
- Disable Bandwidth utilization, disable green power ethernet
- Disable frameburst support
- Enable broadcast/multicast rate limit
- Manually set channel to 6 and 11

We also have many disconnections :
