@SpeersP wifi signals lose power every time tgey pass through a so,id object like a wall and are blocked bybany metal in the path. Like most routers Sky hubs have aerials arranged to maximise signals horizontally. Apart from ensuring the hub is in the best possible position which is as centrally as possible out in the open on a surface so it is above obstructions like radiators there is not much more you can do without spending some money. If your property has solid internal walls you can hit issues in quite small homes bunglalows included.
Sky will sell you an add-on like their WiFi Max package which can give you up to 3 extender units if required to 10Mb/s in every room rising to 25Mb/s if you buy an Ultrafast full fibre service. You can also buy your own whole home wifi system which can work out cheaper in the long run.
