Here are some additional possible explanations:
- You may have entered an incorrect password or the password is too long (a maximum of 63 characters is allowed).
- Your phone or tablet is not connected to the internet or is too far away from Joule.
- Joule may be too far away from your WiFi router / access point.
- You are not the WiFi owner of Joule. Please see: What does it mean to be Joule’s owner?
- You may be trying to connect to a 5 GHz WiFi network. Joule only supports 2.4 GHz WiFi networks.
- You may be attempting to connect to a network with an unsupported security protocol (e.g. WPS, WEP). Joule only supports WPA, WPA2, and open security protocols.
- You may be trying to connect to an open (unsecured) network with a captive portal (a web page you must pass through to access the network). Joule does not support captive portals.
- You may be connecting to a router with MAC address whitelisting enabled. With Joule plugged in and connected, you can find its MAC address in the Joule app on Settings > My Joules > [Joule’s name] > About Device.
- Fully restart your phone / tablet, WiFi router / access point, and internet modem.
- Please unplug Joule, close the app, plug Joule back in, open the app back up, and try again.
- To ensure that Joule’s WiFi is working, try connecting to an open (unsecured) network, mobile hotspot, or an alternate access point. If the connection is successful, please check the settings on your router again.
- Finally, please refer to your router / access point manual or contact your internet service provider to see how to check these settings on your individual equipment.
