I am looking for advice on setting up a mesh network, I have been advised to use TP Deco in Access Point Mode, I have Sky Q which I understand makes it more complicated to set up mesh networks.

My main issue is that my PS Portal is unusable, I need a better connection in my conservatory and the connection to my ring doorbell is poor.

I have full fibre 150 (always been naff) and a Sky Hub 4.2.

Sky Hub is in my office on the 2^nd story, I have an ethernet cable that rubs from my Sky Hub through to the outside wall, it then goes down my driveway and into my living room on the 1^st floor.

This ethernet cable then connects to another ethernet cable (in place before the Sky Hub was installed on the 2^nd story, my old router was in the living room) that runs back down the driveway, into my garage (detached) and connects to an outdoor access point which provides a WiFi network for my garden and ring cameras.

My Sky Q box is in the living room on the 1^st story connected to the satellite dish and WiFi, I have one mini box on the 2^nd story in a bedroom.

I can run ethernet to the Sky Q box, I would just need to put an ethernet splitter/switch at the point where the ethernet cable that runs from the hub enters the living room.

I am terrible with network and WiFi, any help would be massively appreciated
