Hi, My installation date was in 24-03-2020, I installed the modem on that day according to video and step-by-step introduction T-mobile provided. But I still don't have an internet connection. The globe light is off and power, 2,4 and 5ghz lights are working. I've tried resetting the modem and restarting it but it's still the same. I have added photos regarding my installation.

You seem to be connected properly, have you also tried the other (blue) connection? It’s usually one or the other that has a signal. If both don’t work then let me know, in that case I will send out an order for a mechanic to assist with the installation!
