Hi
I am receiving many complains about Teams and Skype being bad under video meetings, that the picture and voice freezes many times. When i check the logs of the AP that the client was connected to i see so many logs as:
#Dropping the auth req recvd in disabled BSSID.... with many MAC addresses which belong to different clients
Another log that comes often is:
%WIDS-6-SIG_ALARM_OFF: Attack is cleared on Sig:Standard Id:9 Channel:52
this logs comes with different channels and syslog numbers.
My envorniment is consist of many 2702 and 2802 AP which are at the same area. I dont know if this is the problem. But it is only some of my 2702 APs that have these logs not the 2802s!
My workround was to reboot the APs, some of them came back with the same logs after being rebooted and some not, still talking about 2702 APs.
Any thoughts about this?!

Hi
It seems to me that you may have some neighbor with wIPS enabled. I had this problem more then once. Usually people who buy Meraki and dont know how to use it, let wIPS enable and they start to drop everything around.
I had to help somenone configure their Meraki once so that I could have my network stable again.

It is only my network that runs the building and no other network are available!!

Hello,
I wonder if these log messages are related to your problem at all. The WIDS messages could just be related to APs being discovered.
Do you have QoS enabled on the AP 2702 (which automatically enables WMM (Wi-Fi Multimedia) ?

QoS is not enabled.
What about the first log: Dropping the auth req recvd in disabled BSSID ?
I have checked CSCve54287 which says that a reboot will fix the problem. Some APs seem to be OK after the reboot but other not!

What, EXACTLY, is the problem?
Clients are complaining that camera under Teams and Skype video meetings freeze
is this happening to one person('s device) or a lot of users?
Happens to many users with Windows PC and Ipad
What firmware is the controller running on?
8.3.133, complains are comming only from one building not all my clients
Have you VERIFIED and replicated the issue?
try to understand what logs mean, will change the AP to different model and check if it will come with same logs
What radio are the issue(s) more prominent?
both 2,4 and 5
isolate and identify what wireless clients are affected (based on OS or SSID or location).
Windows 10 machines and Ipads. Windows and Ipad are connecting to two different SSIDs
What, EXACTLY, is the error message being displayed?
logs from the AP:

Workround according to the webpage is to reboot the AP, which is not giving the desired result. I still getting Dropping logs!!

- Then you need to engage with Cisco TAC (mention the bug report too)

Right that is your first problem - you're running on obsolete code. No point contacting TAC they'll just tell you to upgrade to supported code so that should be your starting point. You don't mention what model of WLC you're using so that affects what version of code you can upgrade to but you should probably be running 8.10.162.0 or 8.5.182.0/8.5.171.0
Then if you still see the same problems then run client debugs on one of the clients experiencing problems and feed that into https://cway.cisco.com/wireless-debug-analyzer/
02-19-2022 06:45 AM
we are using 5520 WLC
Have many 2600 AP model so we cant move to 8.10.162.0 just yet but we are planing to move to 8.5.182.0 soon.
Why is this happening only to 2700 model?
will run the analyzer and get back with result

Are they using MS Teams version 1.5.00.2164?
02-20-2022 12:39 PM
It is version 1.4.00.35564

Sometimes a bug can affect a specific model or models of AP.
2600 is 11n, 2700 is 11ac wave 1, so you'd expect them to be running different code (although they are both running Cisco IOS). 2802 is 11ac wave 2 running AP-COS so another completely different set of code.
