Subject: [WIRELESS-LAN] Android 10 Weirdness - Cisco

Hi Gang,

I'm not sure how much of a problem this is on our network, and I haven't spoken 
with Cisco TAC yet. But I wanted to share what I have seen from a client, in 
case anyone else has seen the same issue.

We are running 8.8.125.0 on a HA pair of 5520s

We have an Android cell phone, running Android 10, that is reported to be 
disconnecting from the network. When I run a debug I see the following 
behaviour:


  *   Client associates to an 1815w in Student Residence
  *   Client performs an intra-roam on the AP from 2.4Ghz to 5GHz, or vice versa
  *   WLC sends an EAP-Identity-Request
  *   Client doesn't respond
  *   Client session is timed out and client is de-authed

This dance seems to repeat whenever an intra roam occurs and has only been 
noticed/reported when they are associated to an 1815w
New associations are fine.

Has anyone seen this before?
Could it be related to this being a sleepy client? Client goes to sleep, but 
the WLC fails to correctly define it and responds as if the client is just 
being unresponsive?
Could it be another AireOS bug?
Is this just a client side bug?

Thanks

Sean
