No, the Network report does not identify specific devices. It just reports poor signal on a device and advice to move the device next to the router (kind of defeats the object of Wi-Fi connectivity).
I have nearly a dozen wi-fi devices around the house covering iPads, iPhones, Printers, laptops, TIVO boxes etc. What use is the VM router if the answer is to use someone else's bit of kit! Surely Virgin media should be able to provide me with appropriate service throughout my standard 3-bedroom house without having to go out and buy a separate and expensive Wi-Fi Hub - I already use 2x WiFi extenders to get a signal from my Router in my study (upstairs) to my TV device in my lounge (downstairs). Just another example of a poor provision of service and support by Virgin Media.
