ASUS ZenWiFi AX (XT8) not compatible with fibre?

We recently moved from copper to full fibre.

We have a mesh network with two ASUS ZenWiFi AX (XT8) and an ASUS RT-AC5300. One of the ZenWiFi AX (XT8) is connected to the modem.

Our new modem is an Adtran SD611 (GPON ONT).

When we moved to BeFibre we were told that our current router would be compatible (they did not ask for any details on the router), however, the red light is showing on the router and when we got back to BeFibre they replied that "In order to use 3rd party router the settings need to be VLAN tagged 10 and DHCP connection"

I now understand that the ASUS router is not compatible (which is why we get a red light) strangely however I still get an internet connection (all devices connecting with expected (fast) data transfers rates). The only issue is that when I connect to the router it does no think it is online and when you e.g. try an update the firmware it says that it has no internet connection.

I guess I can carry on with the current setup as everything is working, but not ideal as I will not be able to update the router firmware.

Any advice on how to get the router back to a white light? One solution is to get a compatible ASUS router and use my existing routers as part of a mesh, however, is there another solution?

Just to complicate matters, for the first couple of days after connecting the ASUS router to the new modem, the white light was showing, not sure what triggered the move to a red light.

which version of the xt8 do you have?

also try this first

ok. try the link above if that doesn't work - yelp.

Thanks. Is the yelp bad news?

Is it not odd that the router (wifi access working) but red light is on?

Is this a general issue with fibre (requiring a router with VLAN tagging)? Can I as BeFibre to change any settings at their end?

VLAN appears to be required for your connection. It certainly is for my CityFibre FTTP via Zen. Have you actually managed to set it on your router?

In reply to a post by ajd1:

You need to set the VLAN on your router. Log into the router and navigate to WAN/Internet Connection/802.1Q.
Enable the VLAN, enter the VLAN ID and save. When the router comes back up the red light will be gone.
(I'm using the fetails from my Asus router but they shouldn't be any different on yours.

I am away until Sunday so will setup VLAN then. Strange that I am getting a connection but at least (hopefully) I am half way there...

Have a read through this thread:

I think that BeFibre may have actually dropped the VLAN requirement on their connection from the ONT. There was however a requirement for MAC spoofing if you happened to be swapping out their supplied router with your own.

This may explain why you were able to get connectivity, albeit intermittently. You may just need them to clear / confirm the MAC address of your router on their end to get things working.
