@RuralBoy to operate properly you need the booster matched to the hub. If you have a black Sky Broadband hub you need a SE210 boister - looks like a white version of the hub - legally none can be resold as Sky have only ever supplied these on loan but they can be picked up on auction sites but are poor value imho. The newer white Sky Max hubs can only work with the pods Sky lend as part of the WiFi Max package buying one of these pods doesnt appear to work as Sky have to add it it to your account.
There is a sokution which is to disable the WiFi on the hub and use a third party system like my own TP-Link Deco system where one unit is connected to the hub by Ethernet. This is set-up to operate in Access Point mode and links to 2 other units on different levels. Cost me under £100 so works out cheaper than paying Sky and will work just as well with any ISP I switch to. Losds of choice in systems that can do that assuming you keep the Sky hub as the router. Connecting directly to the line is slightly more complex.
