We recently bought the network extender and after a frustrating couple of hours stuck on step 8a we got it connected. I went from 1 to 2 bars to full 5 bars! I was so happy! For about a day. Now I have 5 bars and I have the little house symbol at the top of my phone that shows I'm connected, but as soon as I make a call that symbol disappears and I go from 5 bars 4G down to one bar and 1x service and usually drop the call. I've tried with Wi-Fi calling on and off. Also when I go into my phone settings and search for a network extender I get an error, and when I dial #48 it says not connected... why? Please help!
