Netgear routers include a feature which attempts to determine the manufacturer of network adapters by their Organizational Unique Identifier (OUI) code.

When WiFi devices randomly change their MAC address rather than using the actual hardware MAC address, this feature may wrongly identify a device.
One way to see if this is happening is to go through the list of Attached Devices and see if there are any mobile devices (phones, tablets, laptops) which are connected to the network but do not appear on the list of Attached Devices.
