I have been having a problem since I purchased my iMac about 9 months ago. Sometimes in Finder, other entities (computers, printers, time capsules) show up. I try clicking on them and it usually says "connecting" and then they disappear. At one point it said I had connected to one of them through VCN. They're all sorts of different names (i.e. David Barnett's Powerbook G4 12, kodak printer...., Robert Alvarez's Computer, etc.). We recently moved and some of the same named computers still showed up in finder on occasion. My instincts told me that even though we had a WEP connection with a password, that others had been able to crack it. So I read up and learned that a WPA2 may be more secure. So I set that up. I also set up MAC filtering and put only our computers on it and told the router not to broadcast the SSID. That was yesterday...this morning I found two new entities in Finder. What is going on? What can I do?
