DOT11RADIO0 Interface Flapping - Cisco 1142 Aironet

Posted on 2011-10-14

I have a strange issue with a Cisco 1142 Aironet that I would really appreciate some help with.

Config has remained mostly un-touched and working since day 1 - the only changes having been the addition of MAC addresses to access-list 700.

Over the last day I have notice the SSID disappears, and all wireless clients are dropped.  If I wait 5 minutes, or re-boot the AP - the SSID is again broadcast and new wireless clients are accepted.

Could anyone offer any suggestions to help troubleshoot this issue ?

Thanks in advance.

    I would say this is an interference issue usually.

    Can you post the Config for the AP and run a tool such as InSSIDer to see what other frequencies are in use?

    Issue was interference as suggested by craigbeck.  Changed to fixed channel rather than 'least congested' and problem went away.  Thanks craigbeck.
