Garden room Ethernet cable connection?

[Bigtree]

Hi all, I am wanting to lay an Ethernet cable down to my garden to get wifi in my garden office and I’m not sure what category I should post it in?

I currently have virgin media broadband and their router in my living room. Off this I have 3 x BT Whole Home discs around my house which work really well.

If I lay an Ethernet cable to my garden office…can I……..

Plug the ‘house’ end of the garden cable into the back of one of my BT discs or does it need to come direct from the virgin router?

What do I connect to the garden office end to get wifi access?

Many thanks in advance for any help/advice

I'd always connect to the Router and not rely on the Mesh network for the most reliable service.
