Yes, or just walk far enough away and then reboot. Or stick your RS2 in a metal paint can / filing cabinet or something else that attenuates the Wi-Fi signal enough that RS2 can’t connect, and so it starts a hotspot instead.
The method I prefer is just to plug in the USB cable between Reach and my computer and setup the Ethernet over USB interface with the computer’s side set to IP 192.168.2.1, then I can just open up my web browser and point it to 192.168.2.15 which is Reach’s static IP address for the USB interface.
The end result is that I can work with ReachView though the USB cable and optionally manage any Wi-Fi settings or modes there. No reboots, walking, or faraday cages required
