I just got back from a road trip to Dayton, Ohio and I kept losing 4G connection on my iPad. The weird part it only happened while in Ohio! I was the passenger and played with it a lot. I would turn off Cellular Data then turn it back on and surf for a while until I lost the connection and I would repeat the process. Once we crossed the Ohio river at Cincinnati I had a solid connection most of the way down to Atlanta. Anyone ever experience something like this?
