Thanks. I was able to use the AT!DAOFFLINE command, however the AT!DAONLINE command just outputs "error". For the DM commands, what is the command syntax and do I just send them over the telnet 5510 console?

As the title says, is it possible to reboot the M1 modem without rebooting the whole device? Or some AT command to trigger the cellular signal to reconnect (sort of like an airplane mode toggle on android?)

No, I don't think so, sierra devices are difficult to work with, much more so than others, so I think maybe people don't work on them much. I personally do it by patching the kernel so it is permanent, I am sure there are other ways to get it done as well. Ah, that's too bad... It seems setting TTL ...

Late update, I had thrown the M1 into a drawer for while after trying to figure out how to fix this problem.. finally fixed it today :D The issue apparently was IMEI related. Did a "IMEI repair" and now it works again. I guess somehow the IMEI was erased when I was flashing different firmware ...

I've tried the fast.mobile.com and other apns listed in the post and rebooted after setting each, no luck

I have the unbranded M1, guessing this thing is blocked from TMO... Or I perhaps need request a static IP for this sim like the person did in that post.

Hi, I recently bought a used Netgear Nighthawk M1, put in my T-mobile sim from my phone to test connectivity and it worked fine in the Nighthawk. Tried again a few days later and now it displays the message "Mobile Broadband Disconnected". I've tried firmware restores, downgrades, factory resets ...
