The Huddly Network Adapter has a LED light that indicates its status. Here is the explanations of the different statuses:

• Black LED/off: Indicates that the Network Adapter is not connected. Check to make sure the power cable is connected.
• Red LED: Indicates that the Network Adapter is on, but that the USB port it is connected to is not providing enough power. Try connecting to a different USB port, or using an external power adapter to provide enough power.
• White LED: Indicates that the Network Adapter is properly connected and is working as expected.
