Difference between versions of spitz x750

The speeds I’m getting from my first gen Spitz are disappointing. I’m on T-Mobile 4g with towers very close and only see barely over 20mbps regularly. I’m wondering if v2 of the same device will give me any better performance and what the main differences between the devices are.

V2 optimized the antenna so hopefully it can achieve better speed.

Can you point me to a thread that best describes how to implement ncm protocol?

Sorry, I mean qcm, not ncm.
