Re: Problem Apple device on wlan

the above log message is a coverage hole alarm..

I dont feel that would be a cause of the disconnect..

I suspect that the idle timeout value on the controller maybe at play here..

Client debugs would be the ideal way to identify the issue but u can simply try and increase the user idle timeout on Controller > General page..

U can use the client debug command --

debug client

To piggy back on Viten.

Apple devices are very clean, meaning they dont transmit a lot on wifi. In most cases, they only transmit when you the user use something on the device. The user idle timeout will age clients out at 5 minutes (300 seconds) if it doesnt see any traffic from that device. This could be what you are seeing.
