Changed my router to an Asus DSL AC68U and have not been able to get any BT channels since, are there setting I need to enable in the router to get back the channels ?
Indeed there are.
In the LAN section , go to IPTV.
Choose IPTV STB Port - none Remove VLAN TAG from DSL WAN - blank
Use DHCP routes - Microsoft
Enable multicast routing (IGMP Proxy) - enabled
Enable efficient multicast forwarding (IGMP Snooping) - enabled
UDP Proxy - set to 0
Think that's it.
With the Asus IPTV will work over wifi (unlike the HomeHubs) providing the wifi client can handled IGMP Snooping.
