disable the radios in my XB7

I have put my XB7 in bridge mode to get rid of the wireless broadcasts and I have disabled the radios in regular mode. Despite this, the XB7 still broadcasts the Xfinity hotspot and it is a strong signal indeed. I don't want any wireless at all in my house. I have more wireless now than I ever have despite everything in my network being hardwired. I am not sure Xfinity is honest about this fact. Any suggestions?
