Nighthawk CAX30 will not connect to 945G

[Racquetrick]

I have Nighthawk app on my phone and when the phone is connected to Netgear94-5G the app tells me that I cannot connect to router. When I manually change to Netgear 94_2g my phone communicates with router. Why am I unable to use the faster 5G?

What Firmware version is currently loaded?

Do you have any MAC Address Randomizer features enabled on the mobile device? Be sure to disable this while at home.

Is Smart Connect enabled or disabled on the CAX30? 

Be sure your device supports 5Ghz...
