How to hardwire mini boxes and boosters

[Ems176]

We have an annex and we cannot get a stable sky connection to their mini box which causes all the mini boxes to drop off the main box. We want to hard wire the mini box and booster in the annex and possibly all the mini boxes in the house. What's the best way to do this? Connect all the mini boxes to the main box or all the mini boxes and booster to the router? 
thank you

@Ems176 Are you talking about Sky Q, and mini boxes? The number of boxes, the number off boosters, you have NOT supplied any workable information to even start assisting with your question!

Sorry 

q box with 3 mini boxes 

1 router and 1 booster but think we will need another. 
the sky engineer mentioned 2 ways of doing this. Main issue is signal and connection of wifi and mini box in annex.

@Ems176 Not a sky Q person anymore dumped it years ago, but have a look at the link below for powerline and ethernet connecting ALL the devices, you would need 2 off as you have 4 devices in total. It may help and get you Ethernet connected, not sure if you can then use the mini's as hotspots.

@Ems176 Going to be doing a Sky Q main box for the neigbour shortly, due to waiting on the FF install and the Hub is now going to be front room as OR have decided, Q is in the back room, and wireless wi-fi is just not going to cut it for sure, no timescale for completion as this has been ongoing since Nov2024, any that tp-link is going to be the first option to try, already got the wi-fi version installed last week and that has sorted out the kitchen area for her, checked last week and NO issues with it currently, adding in the wired will not be an issue but due to the time and waiting cannot say yah/nah, hope that it works out, if you get from Amazon or a place you can return if not successful.
