I see mixed posts already for similar issues over a broad range of Teltonika devices.. we purchased two TRB140's to use for basic LTE failover at customer sites. Advertised as LTE Cat 4 (which has theoretical throughput up to 150/50Mbps) they seemed like a reasonable solution.
I have so far been able to achieve a max of between 3-8Mbps across both devices, both devices are on different provider networks with different sim's in different locations. I have tried disabling almost everything in the TRB140 and configured as a bridge with no change.
I can install the SIM's in other devices and get 30-100Mbps+++.
Comparing to mobile phones is unreasonable (cat15 devices for example) but I would like some transparency about these devices and for Teltonika to be honest about real world, theoretical max throughput for the TRB14x series devices based on the hardware used.
