I have two NAS Drives and 1 USB drive attached to my router. there are also memory slots in HP officejet printer. And I have one MAC attached to network full time and one portable MAC attached to network most of the time.
I have 1 windows 10, 2 windows 7, 1 windows 8.1, 1 Mac OSX 10.10, 1 MAC 1 MAC OSX 10.6
The Macs see all the network computer and attached NAS drives and drive attached to router, the PCs and the Macs
All of the PCs only see other windows computer.
