I've also had chronic disconnection issues. The software disconnects and is unable to locate the Helix, even if I close and reopen the software. My initial problems were with a new Windows 11 PC on a wired connection and the Helix on WiFi. But I've noticed the PC also disconnects when connected to WiFi and not hardwired. Rebooting either the Helix or the PC seems to temporarily resolve the issue.
I also have a Macbook that's a few years old, which only disconnects when the laptop is left unattended and goes into power saving mode. I am able to easily reconnect manually after the computer wakes. I've wired most of my house with ethernet cable and I also have a dual band router with 2.4 GHz and 5 GHz bands. The Mac's connection to the Helix is solid when on either WiFi frequency or even with WiFi turned off and connected to my network via cable. The connection is stable regardless of which of the two WiFi channels the Helix is connected to.
My plan for the week is to test every combination of computer, computer LAN connection method, and Helix WiFi channel for an hour or two each to see which variables affect disconnection the most. The machines, Helix and WiFi router are all in the same room, so signal strength is almost certainly not an issue.
