(use your cell phone to find the best 3G coverage). make sure that the vents on the unit are not blocked. move the unit to a cooler area. The system will start working normally when it cools down. The signal from the wireless network is too strong to use a booster. Issue The Window and Coverage Units are too close together (low coverage number displayed), or the Window Unit displayed signal level could be higher. Try This move Coverage Unit further away from Window Unit to achieve a coverage unit number of 8 or 9 (even placing the Coverage Unit at the opposite end of the house). a higher number means better coverage. You can also improve performance by moving the Window Unit to a location with higher signal. The more bars the better!
