First of all.. I tried the search feature but I could not find any answers to my problems. I have 4 computers, 2 PC desktops and 2 mac laptops (MB and MBP). I also have a playstation 3... all of which I want connected to the internet. My router is a linksys wrt54gs. The two PCs are connected through a eternet line, the PS3 is connected wireless. The problem I have is that my MB or my MBP (both running latest version of leopard) cannot connect to my router if I have it protected. WEP or WPA does not matter. I enter the correct passwords, and I keep getting connection timed out, but if I keep retrying I might get in once or twice. If I take off the protection on my router, the MB and the MBP connect just fine and never lose connection, but for obvious reasons I do not want to have an unprotected network. I've tried so many different things, but I am just stuck now. Any feedback would be much appreciated. EDIT: I should also mention that when friends come over w/ their laptops they have no issues connecting to my wireless network while its protected. HP and Dell models.
