We had weak wireless signal (VZ) at our location on the lake so I had, several years ago, added a cell repeater with an antenna on the roof. It worked OK. We also had Fairpoint DSL internet with a 3 Mbps download speed that was good enough to to stream Netflix.
Two things have changed. The iPhone (and maybe others) has a WiFi Calling feature that routes calls through WiFi if the phone signal is weak. I turned off the cell repeater and find the calls are pretty flawless now with the WiFi Calling (even better if I make iPhone-iPhone calls using FaceTime Audio), even in my steel-roof house in a weak cell zone.
The second thing that has improved is Fairpoint is now pairing copper phone lines to boost (double) DSL speeds. So, I now have a much better DSL model/WiFi router that downloads at 7 Mbps that I can even connect to from my neighbors house over 200' away. So now I can stream video and not have to tell everyone else to stay off the internet to avoid buffering. Very happy.
