LB2120 Modem not connecting

My power light is blinking green. This all of the sudden started happening. Now I cannot connect to internet. We use an ATT sims card in the modem. What does blinking light mean?

Hi Marquegib

 

Welcome to NETGEAR Community!

 

If power LED is blinking green bar. The modem uses mobile data because the wireline connection is down and the modem failed over to the backup Internet connection over the mobile broadband network.

 

Here's a reference for LED descriptions:

Please describe your network setup. How did you setup the LB2120? 

 

Regards,

    It was working for a month and a half then all of the sudden stopped. I replaced sims card today and restarted my modem. It’s still not working. It’s doing the same thing that it was.

      Please describe the Signal strength bar LED. 

      Have you tried factory resetting? 

      How did you setup LB2120?
