Hi, GDowns1969 - The xFi Devices screen shows what devices are connected to your gateway, not PC. It has the name of manufacturer and the last 4 of the MAC address. For example, if you have an iPhone - it's going to say Apple-1234, if it's an HP laptop HewlettP-1234 and etc. You can rename the devices and assign them to different profiles you may have. If you need help with figuring out what are those devices - please send me a screenshot of what you see and I will do my best to help.
