I've replaced the router on the CityFibre FTTP connection with a 3rd party router which is connected to the ONT but it can't connect to the internet.
I've setup the 3rd party router using the instructions here: https://community.talktalk.co.uk/t5/Articles/Set-up-a-non-TalkTalk-router/ta-p/2205383 and I've set the VLAN ID as 101.
I believe the issue is that CityFibre FTTP uses a VLAN ID of 0 but I can't set the VLAN ID as 0 on the router I've got.
I am going to plug the new router back in and leave it in the hopes that someone can set the profile and when I wake up tomorrow it will magically work. x
Can a change be made to the FTTP profile so that the 3rd party router will work on the CityFibre FTTP connection?
I've update my community profile to include my name, account number and contact number.

The current support team do not have similar access to Full Fibre systems to help you with this, @ssechaud82.
The previous team were trained up for this but are no longer on the forum.
Your only option is to try to follow up with the contact details you were given above, or try 03451 720074 [they close at 7pm].

I have already contacted Talk Talk support and they have told me that third party are not recommended and that they cannot help. I saw that another customer had the exact same problem last Feb and posted here and had the issue resolved. Here is a link where you can see the exact same issue was resolved in Feb for another customer. LINK: https://community.talktalk.co.uk/t5/Full-Fibre/3rd-party-router/m-p/3098743
I was hoping that I could get the same help as the person in that thread.
