I have a AC68R and a MyBook external Hard Drive. I have several PCs, one is wired to the router, the others wireless. The wired one is running Windows 7 Ultimate, the wireless are either 7 or 8. I want to be able to see the my book from any of the pcs and assign it a drive letter. Right now the only way I have been able to get all of the pcs to see it is to assign it as ftp. I was under the impression this was how NAS worked, but I cant get this thing working the way I want.
