Newbie here. I just got a new GL-X750 (OpenWRT 18.06.1) w/ EC25-AF FA modem. I popped a fresh AT&T Prepaid SIM in, and turned it on.
The main screen on the admin panel shows AT&T w/ 2 bars, but never connects (shows “Abort” button) and the IMEI field is blank.
I need to tell the carrier what my IMEI is so they’ll allow the device to use their network. How can I get it to show? Is there an AT cmd to show it?
I don’t know if I have 2 unrelated problems (can’t connect, and IMEI doesn’t show) or a single problem (can’t connect, and thus the IMEI doesn’t show – though I wouldn’t think that a successful connection would be required to display the IMEI).
Anyone got a hint for me?
