I'm having trouble setting up a new router

I have my RJ11? cable from the OpenReach modem to the new router. The wifi of the new router works but I have no internet (or WAN) connection.

I've used the details given here to try to set up PPPoE (though that page says PPPoA), using my Plusnet username@plusdsl.net and password (which let me in to the member's area).

If I remove the cable and plug it into my old (i.e. Plusnet's) router I can connect to the internet through that. There's an option to provide the MAC address, but I've seen advice that I don't need it - and how do I find it anyway?

I can't think of anything else to try. Does anyone have any ideas? Thanks!

I found the MAC address of the Plusnet router on the bottom and copied it into the settings, in case the router was whitelisted but it didn't work

The MAC address is not needed, but you will need to set up a VLAN 101 I think, I am sure there are some setting on other threads. I am assuming as you mention an Openreach mode you are on Fibre?

That page says this for "Using a router with an Openreach modem"

If your fibre router is connected to a BT Openreach modem, here are the settings you’ll need. Some of these terms can vary from router to router, but these are the most commonly used.

It asks for:	Use:
Broadband username or login name	yourusername@plusdsl.net
Connection type or encapsulation	PPPoE Always On

Might be best to factory reset the new router.

Have you made sure the router firmware is upto date?

Have a look at this setup, its not the same router, but does sho the relevant settings.

I'm sorry, I have an ADSL modem plugged into the Openreach wall socket. I don't have Fibre, just ADSL

[#7]

The WAN light on my router is not lit. Perhaps I have faulty hardware?

[#8]

Is the ADSL modem sending the login details to Plusnet? If so, then the router wont need to do that.

Ah then you should be using PPoA.
