Accessing wireless from my Macbook?
This should work, but, as this is working with tech, you never know:


Open System Preferences.
Select Network.
Select "Wi-Fi" on the sidebar (AirPort if you're running SL or earlier).
Click "Advanced..." in the lower right.
On the Wi-Fi tab, click the plus sign beneath "Preferred Networks".
Enter the name of the network that you want to connect to.
In the security drop-down, select "Any (Enterprise)".
Log in with your username and password.
Press OK.
