TP-Link TD-W8970 with Fibre

[#1]

Hi,
I just bought the TP-Link TD-W8970 modem router and I want to know if I can use it to replace both the BT Openreach modern and the router I received from plusnet(technicolor something) instead of only using it as a router. I tried to search but nothing clear came up so I hope you can help me.

Thanks

edit: When I plug the ADSL cable into the modem the ADSL light keeps flashing and then it stops

welcome to the forum
nope you can't, it's an ADSL modem not a VDSL modem which is required for fibre.
this would be what you needed if you wanted a tp-link one http://uk.tp-link.com/products/details/?categoryid=3788&model=TD-W9980

It's a ADSL modem router, so sorry you'll still need to use the BT modem with this router.

To replace the BT modem you need a VDSL2 modem router.
You can however use it to replace the Plusnet TG582n router. Connect the BT modem to the routers Ewan port and configure the router to connect using PPPoE. You'll also need to enter your Plusnet user-name and password in the new router.

Interestingly the hardware of the TD-W8970 may be VDSL2 capable, but the stock firmware only supports ADSL, and there's no easy way to install openwrt or any other custom firmware. So it can't be used as a VDSL2 modem.
It's only advertised as 300Mbps wireless, but it evidently has 3 antenna, and it certainly indicates it can receive MCS 0-23, so it seems to actually have 450Mbps wireless.
