Nighthawk M2 (MR2100) still show Mobile Broadband Disconnected.

[Thanathat]

 I use Netgear Nighthawk M2 (MR2100) but the cellular is still disconnected. I got into the web UI interface to check cellular status, but it is still searching. I have already done a factory reset and many things for example setting APN, changing SIMCard, and cellular network but it is still the same. I'm not sure if it already happened after I updated the firmware or not because It worked before. I attached a model.json file and some screenshot to analyze this issue.

Based on the logo printing, this is a MR2100-1TLAUS (Telstra) version, not a global generic one one from what I understand.

Well possible, the "global" 3G WCDMA support does more and more disappear on the different mobile provider networks, in favor of 4G and 5G, these channels are migrated to different services as RF bandwidth is not an endless ressource.
