Using Asus RT-AC86U 2018 with old bt open reach modem works fine with IPTV BT Sport channels with Plusnet....
was using before Asus DSL AC88U (modem router combined) for over 12 months with constant wifi drops and scrambled
IPTV channels pixellated and distorted sound... when viewing the channels... when not viewing the channels and having left the Plusnet youview channel on 101 BBC 1 HD all is fine, but leave it on a IPTV channel and all hell breaks loose with no wifi
takes some time to find out what has happened... until you turn back on the tv and change the channel... so beaware of this
if this is a model you are interested in, the above router only Asus RT-AC86U is a different machine night and day using all the above.... if you only need a good router without IPTV both are fine.
