"Have you tried turning it off and on again?"
This common turn of phrase for troubleshooting electronics may sound cliché, but there is a reason it is so popular. Occasionally when switching devices over to a new network, a full reboot or 'power cycle' is required in order for your device to fully accept the new SSID/network. This is especially common in devices that remain constantly connected like wireless thermostats, doorbells, etc.
- Try turning your device off for about 10-15 seconds and turn it back on.
- Reconnect your device to your Plume network
If this did not work, try forgetting the network in your device's Wi-Fi settings and then reconnecting it.
