Using a Deco Mesh as the router instead of Sky Router :: Sky Broadband

Hi,

I have Sky Full Fibre 500 and a Sky Max Hub.

I also have a Deco mesh PX50 network which is connected to the Sky Hub - and working in Access Point mode.

I want to switch to using the Deco PX50 as the router and not use the Sky Hub at all - to avoid two different Wifi networks.

I know I could potentially still continue to use the Sky Hub as the router and disable its Wifi - but that is then just using am extra power socket, ethernet cable etc unnecessarily.

According to the TP-link Deco FAQ it should be possible to use the Deco as the Router - but the instructions are confusing.

I did do something similar for my Community Fibre router - i.e use the Deco as the router and put the CF one away - that was pretty easy and straightforward.

Can someone please advise the detailed settings I would need to set/copy across from the Sky Hub to the Deco when I switch it to Router mode so that it can connect to Sky without the Sky Router?
Thanks!
