I could not watch IPTV (Vodafone Spain) with XR500 and XR700, all attempts for iptv and ip voice with the valid configuration were a failure. The only thing that works by setting the operator's VLAN / Bridge was the internet connection.
I think it's a firmware problem, the configuration for operators IPTV in manual mode is basic.
I have an Asus RT-AX88U configured and working IPTV, internet data and IP voice for vodafone TV Spain and in less than 10 minutes everything was working perfectly ....... with XR500 and XR700 I was losing more than 10 hours and only I run data from the internet in the ports and in the deco but nothing from IPTV channels and IP voice.
I would like to put the Netgear as the main one but I can't do without TV and phone calls ... for the moment my main router is Asus.
