Is there something I'm missing that is required when connecting to an Openreach modem, does it need more than offering ppoe for example? I only ask because if I filter by fibre routers the cheapest one is around £50, and the TP Link one is a lot cheaper but simply not listed under wireless fibre routers.
No - you are not missing anything.
The routers which work are not dedicated fibre routers which, presumably, is why sellers do not list them as such.
It is a router, not a modem router. As you say - as long as it can connect a PPOE session over an ethernet input connection it will be fine.
