Wireless clients deassociating

Hey,

I am running an ap with s/w 2.9.46 and a xr2 wireless card. i am experencing a problem with 15 clients dropping out and reassociating every 15 minutes. On the log it says–wlan1:disconnected, got disassoc: class 3 frame recieved (7). I get this error on all clients and then a second later they register again. I have changed channels, preformed channel scans and snoops to see if it is interference but i have a noice floor of -105. Any one have any ideas.

Thanks

Start by upgrade to 2.9.51 or V3.

Upgraded the firmware on the AP and still getting the same errors. And still having clients drop off

What are your hardware retries set to?

they are set to 15

Decrease them to 4
