Hey! I have had a wireless router workin on my macbook perfectly for ages now, and I have recently put a WPA password on it, (don't know why I didn't do it when I first had the router). I can connect to the router fine with the WPA password on my mac G5, but I cannot connect to it on the macbook. When I run network diagnostics on it, I see no option in the drop down list of wireless securities for WPA. What shall I do?
