@AJQ320 every home is different but if you have an older home with solid walls you will have issues modern homes with 3 floors also can be a pain. There are things you can do to help first is make sure your hubs and any boosters are out in the open ideally relatively high so they sre above things like radiators and furniture never hide them away in cupboards or behind the TV etc. Second is move any kit using wireless away from near the hub. As I posted earlier boosters should be placed half way between where you need the signal and the hub as they need a decent signal to boost.
Personally like quite a few others on the forum dont use the Sky hub's wifi but have bought third party gear to get a decent wifi signal through out our houses. If your issue is one room say used as a home office powerline is a decent solution.
