It’s the same thing with my trb 500. I got 900mbs with the iPhone in the exact same position as the router (the trb is connected with the newest poynting 5G antenna 4x4 MIMO)
But with the Teltonika I can reach at least 230mbs …
This is a known issue with the TRB500 gateway. That’s why I switched to the Amit IDG450 gateway, which has a similar design and is also based on a Quectel modem, but a newer one, the RM520N.
It doesn’t matter whether it’s in NAT or bridge mode, the speeds are the same, in my case 800-900 Mbps. With the TRB500, I never exceeded 200 Mbps in bridge mode.
I’ll also add that, just like with the TRB500, the Amit gateway doesn’t use an external processor but rather the one in the modem. Therefore, I believe the issue with the TRB500 is related to the software, not the hardware itself.
Yes, this has been brought up on the forum several times, and Teltonika sort of promised that they would look into it (but could not guarantee that something would be done about it).
There apparently is an issue with “acceleration” software that is supplied by the modem manufacturer.
