I received a 4g lte signal booster recently and after getting both units set up the window unit power button keeps flashing green and the coverage unit had the seven segment cycle going on. According to the start Guide this means they are connecting. So I waited. For around 5 hours. There were no errors they just kept trying to connect. I thought they might be defective but when I moved the coverage unit closer to the window unit I got the zero telling me it was too close to the window unit so I'm not sure if that's the case. What should I do?
