Is this confirmed that there is an issue? I have been having problems as well. Only showing 2-3 bars most of the time, before I upgraded to iPhone 7 it showed straight 5 bars.
That is a good question and I would be more than happy to help. It is important to us that your network extender work properly with your smart phone.
We do not have a reported known issue in regards to the 3G network extender. Just for clarification, have you added any new apps or software updates since purchasing the phone? Have you reset the extender as of yet Connect and Power On - Verizon Wireless Network Extender - 1X/EvDO/Business | Verizon Wireless ?
I don't think it is possible to reset the network extender? I know for sure I can't use wifi calling otherwise it won't connect to extender.
If you have internet, using a wifi router, you don't need the extender. Use wifi calling. That is basically what the extender does...connects you to the internet to send/receive Verizon calls/texts.
