I've put the usb drive to the Aimesh Node router but now I cannot access it. I can see it from my network but when I try to open one of the shared folder, it prompts for username & password, I've tried using the one from my main router or even the default password but nothing works so far, anyone have any suggestions? I could put this on my main but it is sitting up the attic so I prefer to have the drive within range. TIA.
