The computers wired to the router can't see the computers connected via WiFi and vice-versa. It is possible to mount a shared folder as a drive in either direction, but the shares don't show up in Windows Explorer. I think this is because the router separates the wifi and wired connections somehow. Anyone figure out how to get around this?
This has happened to me before. I created a folder on the desktop or each computer and labled it Desktop. I then right clicked on the folder and enabled file sharing on the folder. After doing so it allowed me to see the shared folder.
I was already able to see shared folders by mounting them as drives. I wasn't able to see shared folders in Windows Explorer. But I have figured out how, finally. I found I had to log in from the wi-fi connected machines to the ethernet-connected machine. So it doesn't seem that the problem was some kind of separation of the two kinds of connections by the router.
