Hope you get your internet issues sorted, Dave. In the meantime, a phone hotspot could be a temporary option.
I've run one off my mobile hotspot before and it worked fine. It can be a bit fiddly if you're doing the setup from the same phone that's providing the hotspot. I think I turned the hotspot on first, then did the setup.
Actually, this would be a good chance to test

EDIT: Added BNB, DASH and about 120+ extra coins from binance you should be able to select them on your devices.
