ATT Cell Booster causes ATT Cordless phones to not work
First the ATT Cell Booster works GREAT and provides EXCELLENT coverage and performance. Exactly as advertised and very easy to set-up. BUT, when I first installed it, it was about a foot away from my AT&T cordless phone for my landline (I know...a what). This cell booster interfered with the Cordless phone. Unplug it, the cordless phone worked great. Plug it back in and none of the Cordless handsets would connect and they all had an error message (which is weird as they use different frequencies for sure). I moved the Cellular Booster to another room (not ideal but the only other place where I had a router connection) and now all is good. If you have a Cordless phone (at least an ATT cordless phone), do not install this too close to the base station.
