Looks like the speed issue has been fixed across the area as we are now all relatively stable.
However, I have a homehub and a single disc. the home hub woks great in the room its in, and slightly beyond. But i have an office set up in a room, at the other end of the house. as the crow flies probably 40 feet. Aware there are walls etc in the way.
So i set up the disc one room away (25 feet) and it picks up the signal from the hub just fine. But doesnt seem to do anything to connectivity in the den, (2 pcs and android gettign much slower speeds). M
