I have a ibook G4 with os x 10.3.3 That I just installed a new airport card in. I was so happy when the computer found the WiFi networks! But when I typed the password in for my WiFi The computer said that my password was not right. So I typed it in several more times but my computer still said that my password was not right. so after changing the password on my router and typing it in on my iPhone I than tried it on my ibook once more but I had the same problem. Some one plz help bring some life into my old ibook.
