Lm1200 green light but no internet
Need help. Cannot connect to the internet but when I log in on the Lm1200 it shows I am connected. Received a new Sim card for att and it worked for an hr than no connection.
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.
