With the factory antenna, I got a borderline wifi connection (power panel outside / router inside). The first replacement antenna I tried failed miserably.
I did find a TP Link directional antenna that let me aim it towards my router. My router showed a much improved connection, so I’m hoping this keeps my Sense from dropping offline: http://amzn.to/2EwSV7a My Netgear router shows the wifi device connection quality and it went from 1 bar to 2 bars (out of 3). I’ll take what I can get.
