WiFi is required to download IR codes to a Puck. Gateway Pucks maintain a continuous connection to WiFi, but Sensor Pucks do not. Sensor Pucks will briefly connect to WiFi during the IR download, and will need to be in good range of WiFi for the duration of the download.
A Sensor Puck will have gotten WiFi credentials from a Gateway Puck, but sometimes the credentials become corrupt - or the Gateway Puck is connected to a network that is out of range of the Sensor Puck.
- Check that the Puck is in WiFi range
- Try power cycling the Puck to reset it's WiFi connection
- Try power cycling the Gateway to reestablish the WiFi credentials across the Sensor Pucks in case a Sensor Puck has incorrect credentials
Note: Using repeaters? Repeaters connect to a wireless network and rebroadcast it into a larger area of connectivity, creating a new network with possibly a different SSID. If a Gateway Puck is connected to the network broadcasted by one device, a Sensor Puck may be trying to connect to a network broadcasted by a different device with the credentials for the first network. Ensure the Sensor Puck is in range of the network the Gateway Puck is connected to.
