Welcome to the Community!
There have been a few posts about problems, and some solution as well.
It would be helpful if we knew part of Sky Q is not working for you (Mini Boxes, etc) and how everything is connected.
In any case, please disable Smart Setup: https://www.bt.com/help/broadband/what-is-smart-setup-on-the-bt-hub--how-can-i-turn-it-on-and-off-
@Mega1 Can you describe the problem you’re having?
I have Sky Q + 1 Sky Q Mini working perfectly well with a SmartHub 2 and Complete WiFi and also know two or three other people with the same/similar setup who also have reliable systems. If you could elaborate on the problems you’re having we may be able to help resolve them.
I have Sky Q + 2 mini box’s were all connected through Wi-fi. How ever the BT smart hub 2 keeps dropping speeds thats super fast. Sky Q on all box’s do not connect up as 5ghz does not run with the 2.4ghz band separation is not there on smart hub2. Do you know how to.
