Wi-fi 4G router (Cefnsuran Farm LD7)
This served us well for several years, but we now have something even more marvellous mounted on the roof. If you are in an area with ropey broadband, but can get a mobile signal this works well as an alternative. It needs to have a data-only SIM fitted, then you're good to go. Can also have ethernet cables attached if possible - depends on where the router is sited in relation to your computer.
