Netgear Nighthawk 5G first impressions

Hi Steve,
I came across your review whilst researching my own Netgear Nighthawk setup, which is… shall we say, still in development! As I’m pulling my hair out (what’s left of it) I wonder if you could offer me some tips on completing the setup of my boat home network. I currently have a Nighthawk M1 4G router which has been working as a LAN wifi hotspot for our devices on board. I recently purchased a Ubiquity Bullet M2HP Wifi booster, which runs on POE. My hope was to plug in the Ethernet end of the Bullet into the Nighthawk and use the Data Offloading function to limit our 4G data usage when there are public wifi networks available. However, the two devices do not seem to agree who is boss, and both want to act as routers. I’ve tried a number of different solutions, but none seem to work smoothly. Do you have any experience with these products and do you have any general thoughts about how to approach this? Would it be preferable to use a separate dedicated router as the hub for my LAN and plug the Nighthawk and Bullet into this router instead? It’s all very confusing I’m afraid.
