Can't access files on USB storage from Windows 10
New Archer VR2800 Router is set up and working correctly for internet, wifi access etc.
I've attached a USB drive to one of the slots, and want to use it to transfer files between a Mac and a Win10 PC on my network. At first it didn't appear to either computer, but after a reboot it's now accessible to the Mac - I can see folders, create and read/write them.
On Windows10 however, the router is only appearing as a Media Server, not as a fileserver, so I can't map it as a Network Drive. I've tried with the usual Network Neighbourhood (the router doesn't show up as a device under "Network" in Windows File Explorer). I've tried mapping to \\192.168.1.1 and also htpp://192.168.1.1:8082 but Windows isn't seeing either of those as valid.
Can anyone help please? I just need to map/access folders on the USB (it's NTFS format) from both Mac and PC....
