Shelly Dimmer 2 loses connection to network within 1 minute

My Dimmer 2 loses connection within 1 minute of connecting to my home network. Wired with no neutral, and a switch. Once it loses connection, the red light on the Dimmer 2 body turns off and I'm then unable to control the Dimmer 2. I need to flip my breaker 5 times to reset it and go through the whole process again. Tried this 4/5 times and the shelly always drops connection. This device is closer to the wireless access point than other shelly devices in my home.

Other interesting things - the standard rocker switch I have wired does not toggle the lights.

Any assistance would be appreciated! Thanks!
