Androids - SGIII | iPhones | Ipads = Smart devices -keep disconnecting even when not moving at all.

Hi

 

, I have a deployment at client site – the client keeps complain about disconnecting and connecting every few sec (even when not moving) while using Androids/ipads/iphones. I checked the issue with the client itself. And it's keep happening – no matter what I'm doing. Keep getting this Death …. stm Deauth from sta: b0:65:bd:39:e8:e0: AP 1.0.2.193-24:de:c6:c0:d9:f1-TAMA_SYSTEM_0d:9f Reason STA has left and is deauthenticated

 

 

 

Controller:3400

AP units: AP-105

AOS tested: 6.1.3.6 + 6.2.1.2

DEVICES: iPHONE5|iPAD3|SamsungGalaxySIII + other android devices.

PC & LAPTOPS seems to keep connectivity without any issue. 

SECUTIRY: WPA-2-PERSONAL-AES

Radio: 802.11N 2.4Ghz only.

Re: Androids - SGIII | iPhones | Ipads = Smart devices -keep disconnecting even when not moving at

A deauth from a station is typical when they roam to another access point.  What is your coverage in that area?

Re: Androids - SGIII | iPhones | Ipads = Smart devices -keep disconnecting even when not moving at

  • I know&aware to that.
  • But there is a good coverage there between good=-59 to worst=-65 -67 , and this client isnt moving at all.
  • The iPAD is on table in a room nearby the ap unit itself.
  • You can see this client connecting and after a few sec disconnecting and so on....forever....and he isnt moving at all.

How many access points can you see in that area that are stronger than -67?  There might be too much coverage.

Can you run the show  ap association client-mac <client mac> a couple of times to see if the device keeps hoping to different APs over and over .

 

And also do a show  ap  remote debug mgmt-frames ap-name <ap name>

 

This usually is only needed for Apple devices but have you considered enabling to validate PMKID under the 802.1x profile or disabling OKC?

Thank you

* i checked it via device trail... (GUI) and no ..it's staying and trying to connect to the same ap unit over and over.... agian the client isnt moving at all (u can also notice it in the logs i posted)

*i tried with vaildate PMKID and without validte PMKID - same issue.

*OKC? please explain - how does this effect ?

Actually OKC it won't apply in this scenario since its only used at the initial communication attempt the device makes to the AP and your devices are already connected the issue occurs after the device is associated.

 

What type of authentication are you using ?

Thank you

kdisc98,

 

Do you have anything like 802.11k, local-probe-response-threshold, or handoff assist enabled?
