Hi @ll,
I've been struggling with a problem for a long time. I'm testing WiFi-Calling and have found out that the call switch to the cell network after around 2 - 5 minutes. I started a debug client on our WLC 2504 (8.3.102.0) and found this:
*apfMsConnTask_5: Jul 03 10:56:19.031: bc:e1:43:xx:xx:xx apfMsExpireMobileStation (apf_ms.c:7521) Changing state for mobile bc:e1:43:xx:xx:xx on AP 00:f8:2c:xx:xx:xx from Associated to Disassociated

But this happens only, if the phone is in an acitve WiFi-Call. If I only use the phone for surfing (even if I do nothing at all on the phone) the WiFi connection remains stable.
Any idea how to found out, why the disassociation happens?
