Redmi AX6000 won't connect to internet

[#1]

Hello, I've a Redmi AX6000 router and trying to get online is proving difficult.
I've read as many articles I can find to no avail.
It was working fine with fftc but not with fftp.
Problem may be the change of leads. Now connected to socket 1 (WAN) and not to socket 3 (LAN). Only socket 1 gives all LED's lit like it was before. Leaving in socket 3 the LED's for internet remain unlit. The display for WAN interface say unable to connect.
Has anyone got a Redmi AX6000 working on PlusNet, if so a few pointers may be helpful.
At a complete loss

@Skuzzer Never heard of that router, but what are the VLAN settings? The WAN port is the correct one, BTW.

Just noted

1 Working fine on Plusnet router not working on Xiaomi Redmi AX6000 running OpenWrt. 

VLAN could be the problem as I can't find where to enter it. Only place I found was in Bridge VLAN filtering. If I enter anything in there it just crashes.

[#4]

VLAN for FTTP is controlled by the ONT - it should be set to '0', blank or off on the router.

If there is anything else in there, it won't work.

I'm not a networking expert, and as I said, know nothing about that router, so if that doesn’t work, maybe one of the more experienced contributors may have an idea.

[#5]

I think it is turned off. It says "Enable VLAN filtering" box is un checked & "This section contains no value yet"

[#6]

I  am not convinced you are looking in the correct place. For that router to have worked on FTTC, somewhere there should be a value of 101 - it is that which needs changing/amending.

[#7]

Couldn't find the value of 101, I tried adding it to Network options but it came up as a greyed out option with the terminal showing as a broken line. Maybe tomorrow I'll take another look at it....

[#8]

@Skuzzer   it sounds like you were using it in DHCP mode when on FTTC - ie it did not need any config, it should work the same way when you plug your PN router into the ONT.

However if you want to use it directly with the ONT, then you need to set the WAN port to PPOE and enter your PN username and password and that is about it.

[#9]

There's some confusion here.
Is this a router only device? Which modem did you use with FTTC, make and model?
If you were using a Openreach modem or a Hub Two in bridge mode that would have provided the VLAN being mentioned.

[#10]

That's what I thought but it still doesn't work

[#11]

This is exactly the same router that was plugged into FFTC now plugged into FFTP. Only difference is the cable now plugged into WAN not LAN.

[#12]

@Skuzzer    why have you changed whrer you plug it into? If it worked on FTTC, it should work in the same place with the PN router now on FTTP.

[#13]

Yes it was using an Openreach modem

[#14]

There seems to be OpenWRT firmware as well as (I guess) "stock".

How was it used with FTTC?

For FTTP it needs to be set to use PPPoE and don't set any WAN VLANS (the Openreach modem covers that requirement).

[#15]

Yes that's what I did similar to:-

config interface 'wan'
    option ifname 'dsl0'
    # option ifname 'nas0' # for LEDE 17.01
    option proto 'pppoe'
    option username 'your username'
    option password 'your password'
    # option username 'bthomehub@btinternet.com' # BT ADSL
    # option password ' ' # Apparently requires any non-empty password such as a space character or 'BT'
