I've got a Revo RL70 (Machine1) and a Dell laptop (Machine2) both running Ubuntu 12.04 on the same network.
I've set up some folders on Machine1 to be shareable. Sometimes, when I open the File Manager on Machine2, click on Browse Network and choose 'Machine1' from the list I can see the shared folders, other times they don't appear at all.
All that hapopens is that the 'egg-timer' thingy turns for a while, the title bar in File Manager says 'Windows shares on Machine1' and nothing is listed in the window.
I'm quite new to Ubuntu and have no networking experience so I don't know where to start with this problem. Why aren't the shared folders showing all the time?
