I'm having trouble maintaining a connection to our campus's network (Clemson University) on my early 2008 Macbook Pro We are using WPA2 Enterprise security and when I first reboot my computer it authenticates just fine and the routers assign my computer an ip. But after a short amount of time (10-30 min) my laptop drops connection and when trying to reconnect I get a self assigned ip. If I reboot, it will connect just fine, but once it has dropped connection it will not reconnect until I reboot again. I have taken it to our computer repair department and they have no solution except that it might be an error with my Airport card. They said that there are different version of Airport cards and that it might be my specific card that does not like their routers. Is this true? Also, my laptop connects and maintains connection in Windows perfectly. Is there any steps that I can take to make it reconnect in OS X without rebooting? I would hate to have to use Windows everyvtime I'm on campus. Thanks in advance.
