Speed issue with LTE modem MC7304 on APU3

[pwe76]

Hello everyone,

I have an LTE Sierra MC7403 modem installed on an APU3,
everything works perfectly except the speed which systematically returns to 5Mbps/5Mbps....

the only solution to arrive at a transfer rate of 45Mbps/40Mbps and to reset the modem with the command AT!RESET...

How is it that when starting the APU the modem never works at the right speed??

Thank you in advance for your ideas,
I have just spent several hours in order to find a solution to this problem.

Is this a new Modem or used?
For used ones there may be old config on the device, you can try AT!GRESET to set to default.
