I have a Motorola RFS4000 controller.  I have wifi client randomly dropping off the WLAN and then automatically reconnecting.  I've enabled a syslog server and got the error when the WiFi client drops.

Is your WLAN using WPA2?  If so the client doesn't like using WPA2 with TKIP.

WPA2 was designed to use AES.  Some clients want to use TKIP only with WPA1.

I think my controller is set for TKIP or AES.  I guess it does via auto mode.  I'll see about statically assigning AES and will update this ticket.

I only see WPA-WPA2/TKIP.  This is no AES option.

AES must be available as you have the ability to use 802.11n.  AES is a requirement when 802.11n is used, unless you use no authentication.

The spec sheet suggests that the following modes are available:

WEP 40/128 (RC4), KeyGuard, WPA—TKIP, WPA2-CCMP (AES), WPA2-TKIP

Can you post a screenshot of the page where you see the TKIP options please?

okay.  When users leave for the day I'll change it to that encryption.  I'll update the ticket late afternoon.

Thanks.
