I've noticed that when I sit near my AT&T Uverse router, my 4G service either switches to 3G or 1X, stalls, or data does NOT function altogether. This happens 75% of the time. This NEVER happened with my OG Droid. I know it's 3G, but there must be a correlation b/t the router's signal and the LTE radio. Anybody have this issue? Is somehow the 700mhz LTE signal conflict with the WIFI signal?
