As an Orange business customer, I've been given a free EE Signal Box after EE decommissioned transmitters in my area. I understand there might be more than one model of the Signal Box, and mine is a Nokia Siemens FAPr-hsp 5000.
I've had problems several times per week, each time with one of two different symptoms:
Constant red light - "product failure" according to the enclosed Quick Start Guide.
Fast flashing green light - "initialisation or temporarily out of service" according to the enclosed Quick Start Guide.
In both cases, I can restore operation by unplugging the power for at least ten seconds and reconnecting it, but it takes a long time to get a constant green light again, sometimes over an hour. Until I notice the problem each time, I miss incoming calls because my iPhone shows "No Service".
I've received a replacement Signal Box (which arrived much faster than the first one) but it encounters similar problems. I've tried connecting them both at the same time which gives excellent coverage, but each experiences the same symptoms intermittently at different times from the other one. Nobody at Orange seems to have a solution. What can I do? Is this an inherent problem with the Signal Box?
