STEER CLEAR of the ASUS (DSL-AC88U) VDSL/G-FAST wireless router, it's a nightmare, full of bugs which they are taking AGES to fix.
I have one which I tried to use on BT Infinity 2, but it's currently back in it's box as it won't work properly with the BT-TV IPTV channels.
The streaming SD channels are ok, but HD is iffy & UHD doesn't work at all, with my TP-LINK router however all channels work perfectly.
It's been nearly a year now since this bug was acknowledged by ASUS but they just keep saying it WILL be fixed in a future firmware update.
Also lots of DHCP issues which are ongoing, many people are complaining that their Amazon wireless devices don't like it either, frequent drop-outs.
