IPTV/VOIP locks up
Since my new AX20 was installed, my IPTV service occasionally freezes. Sometimes it unjams within seconds but most often, i need to change channels and come back.
I have QoS turned on and the issue happens whether by LAN (via tp-link powerline adapters) or by wifi. I marked my IPTV box as high priority. There does not seem to be any freezing when streaming to my Roku stick.
This also affects my VOIP phone where my device ceases to be registered and I need to unplug/replug from the router to reconnect it.
This did not happen using my original linksys router.
