Just got my Signal Booster yesterday, and the booster by the window has full bars flashing and LTE light on. The other similar Box that came with it, that goes in middle of household flashes error code "E7". Not sure whats going on. Turned off and on, moved around and still having same problem. Called tech support and looks like they are sending me a new booster. From the looks of it, a bunch of people are having the same probleme with error code E7. Hopefully the new one will work, but I dont know if it will.
