Hi @cleanerairPlease, if you are connected to the PurpleAir-\*\*\*\* network but the configuration page does not appear, open a web browser and visit [http://192.168.4.1/config](http://192.168.4.1/config). Ensure that you are connected to the PurpleAir-\*\*\*\* network when doing so. The configuration page should appear and allow you to configure your device to the WiFi.
