I am a new user of Amcbook - wonderful experience apart from WiFi. My belkin Wireless router was security set and when my Macbook asks for security key, I correctly insert it but it is rejected saying "password incorrect". The other message I get is time-out occurred. I have disabled security, on Belkin, and Macbook Air connects OK!, clearly not a permanent solution though. I can also connect to other wireless netwroks in my area such as BTFON, again no security though. I have no problems connecting to my university network - just clicked and went OK first time no hitches. Can anyone help please.
