I have two portable computers that normally connect to my local network wirelessly, but can be connected via ethernet, and two desktops that connect only via ethernet. When connected wirelessly, the portables can see the desktop computers, and the desktops can see the portables, but the portables can't see each other. Everybody can see everybody else when all are connected via ethernet. Any ideas as to what the problem could be that prevents the portables from seeing each other when they are connected wirelessly?
