Over time, my EA6300 router accumulates increasing numbers of "Network Device" nodes. I have no idea which device this is because none of these have any IP information when you click the "i" icon. Does anyone know how to keep this from happening? It's a huge pain to have to scroll through all this just to find the device that's actually live and connected. I don't care about devices that are disconnected. Especially non-descript ones like these.
