I have the RT-AC68U and when i first set it up I was able to use my android phone with the aicloud app and download mp3 files on a shared folder on my windows 10 pc outside my home network. Then one day I was no longer able to download the files outside my home network. When I would click on file download in the aicloud app it would say file transfer failed. Now if I am home connected to my network it will download. Can someone please help me with this. I called Asus support but they just blamed it on windows.
