Frequent wireless client disconnection

[Angus Bishop]

HI ,

I am using WLC 4402  with the code version 6.0.199.4 . I am using the WPA2 authentiction with TKIP encryption .

My clients are getting disconnected frequently ( 5 - 10 minutes ) . Clients disconnects and connects back automatically .

I have captured debug client and attaching the same .

Please find the attached show logging and debug client output attached .

Thanks in Advance !!!

Regards

Hi Angus,

It looks like this wlan may have a restrcitive session timer or aaa override and the radius server is timing out/deauthing the client.

Note the time difference in these particular debug outputs:

*Jul 22 15:51:41.062: 1C:65:9D:E6:A4:4E DHCP successfully bridged packet to STA

~about 5 minutes~

(Cisco Controller) >*Jul 22 15:53:58.210: Ignoring 802.11 assoc request from mobileradio is NOT enabled

*Jul 22 15:56:29.558: 1C:65:9D:E6:A4:4E Cleaning up state for STA 1C:65:9D:E6:A4:4E due to event for AP 00:3a:99:a9:e9:d1(0)

*Jul 22 15:56:29.559: 1C:65:9D:E6:A4:4E apfSendDisAssocMsgDebug (apf_80211.c:1683) Changing state for mobile 1C:65:9D:E6:A4:4E on AP

let's take a look at the output of show wlan x (x - whatever wlan this client is associating to)

Hi Jeffrey

I have tried increasing the  timed out value for the radius server and found the issue got resolved .
