Ok so since I bought I laptop I moved my iMac 5,1 into my kids room. I had leopard on it but it always had buggy issues so I went back to running tiger. Literally hours before when it had leopard everything worked fine. (On the internet). Since I reverted back, the mac will not connect over WIFI. I am absolutely sure I typed in the correct password but it will keep saying password not correct for airport. Or simply it would not connect. The password issue is weird though since I actually changed it, reconnected my laptop and iPhone with the new password and I get online. Any suggestions?
