Hi Dave,
At work, Fire Station, we do have a heavy duty wifi set up so that explains the problems when I ride the rollers in the bay. The problem is now occurring everywhere. For example one of the rides I mentioned above it read just fine for the first 20 miles or so then turned off out of the blue. I tried to 'learn' while riding, also 'find' and nothing. The computer then went to sleep and when I stopped up the road I turned it back on and tried to pair the HS which it did and the hub worked also. Today after traveling home from Flagstaff To Tucson it isn't working again and will not even pair the HS. My guess is the computer has a short since it will not pair the HS? Looks like I have to ship it in.
