I am doing my best to improve the performance of my LTE internet and landline phone. I think I work with a Verizon tower that's packed with tourists on the weekends. I have a good signal, but the signal-to-noise ratio keeps getting worse because it's crowded. This device actually degraded the SNR without increasing the signal strength. And I had to experiment because the instructions don't say which cable connects to which port on the back of my device.
