Asus RT-AX86U Pro not providing internet

[AquilaJT]

Hi there, so we have had major connection issues since changing to sky and decided to try a 3rd party router as most of the issues were wireless connectivity.

We have since got the AC86U Pro

All setup was easy, we followed other forum posts here and setup the DHCP client ID etc but it still provides no connection and with no real explanation as to why.

Does anyone have any idea, has the client ID changed recently or?

Which variety of broadband technology (ADSL, FTTC, G.fast or FTTP) is this?
