Which model TP Link router is it?
That is an ADSL modem/router rather than a VDSL modem/router. You need to look at either the 9970 or VR600
I assume you have Infinity rather than standard broadband.
Oh dear, Maplin don't seem to have much of a clue. You were advised on here to get a VDSL modem/router.
This is what you need TP-LINK Archer VR900 AC1900 Wireless Dual Band Gigabit VDSL2/ADSL2+ Modem Router for Phone Line Connections
Bought Nd set up TP-LINK VDSL TD-W9970 today. Immediate connection to all devices including those that have failed to connect to BT smart hub for 4 weeks. Seems like problem is solved. Poor quality BT kit. Thanks to all contributors here for your help.
But it does not look as nice as the hub 6
Its all about marketing these days, it does not matter if it does not work very well, as long as it looks good.
