I have a Alarm Panel 2 board and a Alarm Panel 2 add-on board. The Add-On board has dropped the Wifi connection, and will not reboot when I press the onboard reboot button. Indications: the blue connection LED comes on for about a tenth of a second just as I press the reboot button. The unit is not apparently trying to connect with wifi. I don't know what caused the unit to drop the Wifi in the first place, so that is certainly a concern.
Any suggestions on how to force a reboot (other than cycling power, which I will do as a last resort)?
