To narrow down "this area" I tried the following:
*) I reconfigured my soekris AP hostapd to use wpa_group_rekey=0
.... and it works like a charm since then
*) I reconfigured the ubiquiti UniFi AP to use wpa_group_rekey=120
... and I'am pretty sure now that it is exactly the second rekeying
that starts messing up the system. Exactly after wpa_supplicant logs
WPA: Group rekeying completed with 06:27:22:xx:xx:xx [GTK=TKIP]
the second time, video streaming with VLC immediatly leeds to all the
mentioned sideeffects.
Maybe it's possible to reproduce it with any hostapd based AP with
active wpa_group_rekey.
Greetings, Wolfgang
