    You  might have to explain this in a bit more detail.

     

    What does "Cannot connect" mean? What tells you that?

     

    Manuals are always a good place to start.

    Visit the support pages:

    Support | NETGEAR

    Feed in your model number and check the documentation for your hardware.

    Check the section in the manual on troubleshooting.

    You may have done that already. I can't tell from your message.

    I mention it because Netgear gave up on supplying paper manuals and CD versions some years ago and people sometimes miss the downloads.

    I also have the same condition.  The LM1200 worked fine for 18 months, then suddenly stopped sending & receiving data at 2AM on 7/29/22 according to AT&T's Data Usage Log.  Tried 1) resetting the LM1200, 2) reset to factory defaults, 3) new SIM from AT&T, 4) connected wireline WAN port to my local ISP and verified latest firmware (version: EC25AFFDR07A09M4G).  The LM1200 shows connected to a tower, aquired an IPv4 address from AT&T, and I can do an NSLOOKUP on a few sites, but absolutly no data transfer.
