I have had an Android TV device, Nvidia Shield Pro, as part of my network, with a wi-fi connection, for years. It showed up as part of my network in File Explorer and was accessible from my PC and the PC was accessible to the Shield. Recently, that all came to an end and the Shield is no longer shown in File Explorer. This is quite troublesome as my media files are all on a USB drive connected to the PC and are no longer available to the Shield. I can get to the Shield from any other device on my network and the Shield gets out to the Internet via my router. Does anyone know how I can get the Shield back into the network?
