So, I just connected to N71 + N41 SA today. In my basement, no less. Speeds weren't too impressive, at 76/11. But it's a start. I don't think I've connected to B41 or N41 in my basement before. Not even when I was with Sprint and they had a B41 site less than a 10th of a mile from me.
In the Parma, OH area.
