Why won't my Network Extender connect to a Galaxy S7 Edge?

[wrestlingrebel]

I have a Network Extender (SCS-2U01) and can't connect to it with my Galaxy S7 Edge. I had a Samsung Convoy and never had a dropped call. I have pressed #48 and the S7 is looking for a 4G signal. Any suggestions ?

I have been using my phone line for business and I am almost ready to return the Galaxy and go back to the Convoy.

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.
