Extend Sky Broadband signal to garage. BUT have sonos.

[supermonkeyball]

Hello all. 

So I've moved house into a terraced property. That has a garage that is at the end of the garden where I'm keeping a classic car. I have set up a Ring camera and realised wifi doesn't reach adequately. 

I have one phone socket at the very front of the house, so have sky's black broadband router in there and 2 sky pucks. I also have 4 sonos speakers dotted around the house.

I want to simply extend the WiFi signal to the garage so I can use the ring camera. However I've read so many horror stories about extenders and mesh networks and how they don't agree with sonos speakers etc. 

Can ANYONE recommend the route I should take to simply take the original 2.4ghz wifi signal out to the garage which is only about 12 to 15 metres away from the current router. 

I'm not remotely techy so, I thought maybe subscribing to the sky booster add on would work for me. But maybe a mesh network would be better ?

If there's power in the garage I'd be inclined to try powerline adapters with a WiFi access point bulit in. Powerline works by creating an ethernet connection across your mains wiring & the built in WAP gives you WiFi where you want it. It requires decent mains wiring & they only way to find out how well it will work in any given circumstance is to try it. TP-Link TL-WPA4221 is an example but buy from somewhere with a no quibble returns policy. There's no reason that should impact on the Sonos kit.
