Herelink WiFi detection problems

I’ve had a few issues with wifi slowdown in NZ. I can only assume because of a region issue which I’ve tried to set to the various options. I expect I should be using US or EU?

i asume NZ is similar to AU, just pick US

But I should try to change country in Herelink in Android ?

I re-flashed the firmware on both the AirUnit and RC using the flasher for mac and set it to the US and it appears to be much better although I can’t specifically say why.
