I'm new to this so bare with me. I have a dual 2.5 g5 at home that I installed an airport extreme card into yesterday. I installed the airport software just fine. Installed the card with no problems at all, connected the antennae. Machine came up just fine, I was able to see the card in system profile. I can't for the life of me connect to a wireless network. I can't even find a wireless network. Nothing shows up. I'm completely lost. Can anyone spare a moment to help me out? Thanks in advance.
