I just got a C-8 Pro with 2.3.9.201 and in the process of setting it up I've noticed that if I switch to Wi-Fi by disabling Ethernet (not just unplugging the cable!) it works... until I need to reboot the C-8 Pro.
After a reboot, I am able to find the device using findmyhub (it shows the device at the wireless IP) but am not able to connect to it. I have to connect the ethernet cable back in and then I am able to access the device at both the wired and wireless IPs.
Am I doing something wrong? or is this a bug?
