The only problem so far is that I can't seem to get into the hub (homehub 4) to check its settings - when I try bthomehub.home, which is supposed to be its URL, I get a not found error. Anyone got any alternatives?
and as if by magic, just tried that again and it's working!
later Thursday morning, and speed is 21.5 download, 7.5 upload, which is pretty good considering I'm not doing many of the things that need that sort of performance. Hopefully it'll stay OK.
