Turbo'd MX-5 MK4
Moved my Sky Q to a wired solution as apparently the mini box in the room directly above the main box struggles to contact each other, anything Wifi related to these boxes appears to be total shite tbh, not great all, god knows how it would work in a larger house, not at all I would imagine without one of those horrible Wifi Boosters.
Also even though all of my connection issues are now sorted, both of the boxes will still randomly freeze or not come out of standby requiring me to pull the power out of back to get it working again, this happens to either box a few times a month.
Sky Q boxes are a great idea badly executed, think that sums them up quite well.
To be honest, I was in a very similar position, but since having the booster installed and the latest update mine has worked flawlessly (main box + 2 mini boxes spread over a pretty large house)
