hi guys, everytime i try to use airport, it connects to the network, and when i click on the icon it has a check next to the network. but the airport bars keep going up and down like its scanning something, and when i try to get on the internet, it says im not connected, on leopard it never had this problem. after like 5 minutes it connects and then i have internet, but its really annoying. has anyone else had this problem? and if so do u know how to fix it? thanks in advance!
