Reconnecting my old wired network to new Sky Hub

[S_Alexander]

I have just switched to Sky from another supplier, where I previously had a wired network connected to the hub under the stairs.
With my new install yesterday, it was not possible to get the Sky Hub in the same location, so, I've lost all my wired connections.
I've been looking at my options, and if I've read up correctly, I believe I can add another wireless router - perhaps an ASUS RT-AX57 (AX1800), and set it up as a client that sits under the stairs, and then connect my wired network to that. My question really is, would this work or have I read too much intoo this. Secondly, how easy is it to do? It looks like there's quite a bit of tinkering with the ip addresses and channel settings. 
Many thanks for any tips or advice.

You definitely don't want a second router.

What exactly do you have under the stairs, a network switch, a patch panel, something else?

What Sky service do you have, FTTP or FTTC?

[S_Alexander]

Hi thanks for the reply. Sorry, I'm unaware of what FTTP and FTTC are. My hub is a Sky Max Hub. 

Beneath the stairs I have a network switch with numerous ethernet cables running into it from around the house. Previously this was connected via ethernet cable to my hub. This is now no longer possible, so I was hoping to set a new router up as an Access Point with a seperate SSID, potentially the same SSID if that works, but I read that could cause issues when devices jump from one to another. 
Many thanks

Does you router plug into a telephone socket or a square box with LEDs on it?

@S_Alexander the simplest thing to do is to buy an Ethernet cable of the correct length and run that from the Sky hub to your switch. This will be far the best solution

While you can possibly use WiFi you do not need a router as such and given the location of the switch in a cupboard it is unlikely to work very well. Assuming there is a power outlet in the cupboard a better solution is to use powerline networking that sends data overvthe mains wiring. You need a kit of two adapters one plugs into a wall socket near the hub and is connected using one of the  leads in the kit. The other adapter  plugs into the socket near the switch and is similarly linked to it. The adapters can come with a pass through mains connection so you dont lose use of the power socket. Assume you will get around 20 to 30% of the rated speed when choising the kit.

If you do want to use wifi then you need a simple wifi extender with an ethernet port.

Its a square box with lights on.

@S_Alexander you have full fibre but thst doesn't change the ways to connect your ethernet switch.

Amazing @Chrisee thanks. I was hoping to be able to use some copper lines that were there from the Virgin setup but thats not possible. The mains adapter looks like a good solution. Thanks both for your help

The reason I asked because I too was going to suggest powerline adapters. But with the FTTP that you have, there's also the possibility to use them to replace the connection to the ONT (square box). So if you'd prefer the router back where it was, you could try a powerline connection between the ONT & the router. But this is unlikely to be satisfactory for a connection above 300Mb.
