And be sure to note exact versions of your OS and machine.
At work, they have wireless network connection setup on one of the computers. When I brought my Windows laptop and tried to connect to the work's wireless network, all I needed was to punch in the password. But when I brought my Mac, I thought it would be just as easy. When I clicked the Airport icon and chose the work network, it asked for a password just like when I was using my Windows. But it won't accept the password. Please help me!
