Working from "Home"

So that R could come home for Christmas and carry on working while we have no broadband,  we bought a mini Wi-Fi hotspot from EE . EE said we could connect up to 20 devices.  Fantastic, we bought 100GB, that'll get R through Christmas and we might be able to watch some catch up TV too. 
But the 4G signal here is rural South Lakes is not consistent and it drops off. Sometimes you can only get H not 4G and that's no good to anyone. So R here has decamped to the café.
