LM1200 drops but T-Mobile SIM is online
LM1200-100NAS Updated firmware upon initial boot up on 11/21/21 T-Mobile 4G LTE SIM with 50GB plan My new LM1200 has a T-Mobile 4G LTE SIM on a 50GB plan. It connects to a Nighthawk AC1750 rout...
John, thanks for your support!
Regarding KeepAlive, is this setting only available when in Router mode? Within Bridge mode, is there such a thing as KeepAlive within the LM1200? Or do we need to figure out something within the LAN Router to send a KeepAlive ping every so often?
Yes. It is available in both Bridge and Router mode. You can find it under Failover tab.
Please make sure you upgrade your device to the latest release.
Thanks
John
I will try this next time I am at the boat slip. On New Year's Eve I added an automatic on/off power adapter and set it to turn off every day at Noon and turn back on at 12:05 PM. It essentially power cycles the unit (auto-reboot of sorts). That forces the unit to establish a new connection to the tower. So far, that has prevented the unit from going offline. I will try the keep-alive feature next time I am up there and report on how that works. BTW, your model listing does not have the LM1200 listed. I chose LB1120 since that was the closest thing.
Did this stay alive setting work for you?
So I assume the LM1200 IMEI was accepted by T-Mobile and that part of the process worked ok? No one at T-Mobile can tell me other than with an IMEI whether this modem will work on their network, so I would have to buy it blindly and hope :-(
LM1200 is certified with T-Mobile. If you get the T-Mobile SIM from their BYOD mobile hotspot plan, the device will work for sure.
The Keepalive setting is just a workaround to prevent the network to disconnect the data link after certain period of time of activities.
Thanks
