I've read through several troubleshooting posts. I've reset and tried everything. I have 4 bars, and one device showing on the extender. I try to call #48, and when the call connects I drop to 2 bars and I get a notice that I'm not connected. My calls have been dropping all day. I've had the network extender just about 18 months. This is the first issue I have had with the connection. I've done this: Turn off Advanced Calling. Change network mode to LTE/CDMA. Get close to network extender and call #48. You should get "You are under network extender coverage". Bars are now at 4.
