Radio Interface Reset and Shutdown Frequently

As recently new office from end-Sept, we have found that the radio interface reset very frequently which has been  happening about over 15 times within 8 weeks for one AP on average. Some of  those (3 AP so far) got the radio interface down eventually and we need to  reload the AP to make it up again.


the AP model is AIR-LAP1142N-N-K9 and the IOS version is c1140-k9w7-mx.124-21a.JA1. Power supply is made from the PoE switch c2960s. Is there any issue related to IOS? or some other factors may cause the issue happen? Any debug command can show the status of AP? Please advice.

Hi Surendra,

Other than IOS, will this radio interface reset and shutdown issue affect by the nearby AP which is not belongs to the same office.

Scenario:

The new office gets 2 floors. One is 5/F which has installed 9 APs with different channels and another one is 6/F which has installed 6 APs with different channels as well. We found that there are many events “%DOT11-4-MAXRETRIES: Packet to client reached max retries, removing the client” logged on 5/F and 6/F AP.

We also found that the radio interface reset very frequently which has been happening about over 15 times within 8 weeks for one AP on average. Some of those (3 AP so far) got the radio interface down eventually and we need to reload the AP to make it up again.

Is/ are there any possibility caused by otherenvironmental factors? Please advise.

Best regards,

Bell

NO!! coz of interference the radios will never go to RESET DOWN status unless we are using ROOT - NON ROOT bridge more..

Not yet. We are just scheduling the maintenance windows as there are 15 APs totally.

I will update you here when the update is done.

Hi Surenda,

We have just upgraded the latest IOS for the AP. In this moment, the status seems fine without any interface shutdown in sudden.

We will keep this into monitoring status.

Thanks for your info and Happy New Year!!!

I agree with Surendra.  Radio interference cannot and will not reset a radio interface.
