I’m hoping for some advice.

I have three Deco units in a fairly old house with thick walls. I’m on Sky Gigafast FTTP.

My main Deco is connected directly to the Sky Hub 4.2 (Wi-Fi disabled). From there, the other two Decos connect wirelessly — one upstairs and one downstairs in the conservatory. All set to access point 

From the router, I run a network switch that connects:

• Sky Q box
• Xbox
• TV

I also have an Ethernet cable running from the router to the conservatory, where it connects via a switch to:

• Sky Q Mini
• Second Xbox
• TV

At the moment, the Deco in the conservatory has a weak signal, so I’m considering wiring it via Ethernet.

My question is about the best connection order:

• Should it be Router → Switch → Deco, or
• Router → Deco → Switch?

What’s the recommended setup for best performance and stability?
