If Prism’s Wi-Fi is no longer visible, turn Prism off and on again via the upstream switch that powers Prism.
If the problem persists, the only way forward is to perform the reset procedure:
- Make sure there are no vehicles in charge
- Turn off Prism from the circuit breaker upstream of the power line and wait at least 10 seconds
- Turn Prism back on and wait 1 minute
- Press and hold the Prism touch button until all LEDs turn purple (use the left button for the Duo version)
- Release the touch button
- Settings are restored
- Once the device is reset, Prism’s WiFi will reappear within a couple of minutes and you can perform the configuration wizard.
