I'm at the University of Texas, where we have a WPA/WPA2 enterprise wifi network. Much of the time it works great. Other times, it's tricky to connect and stay connected.

I can actually force it to connect long enough to load a webpage or two if I go into System Preferences > Network > Wi-Fi. In the bottom half of the window it's got 802.1X: Wi-Fi (restricted.utexas.edu) next to a Connect button.

If I push connect, it says:

Authenticated via TTLS
Connect Time: 00:00:00 

and then starts counting up. When it hits about 5 seconds, I find that I can load webpages. The Wi-Fi indicator, however, seems to think it's not connected (won't show the solid connection indicator, just the trying-to-connect animation), and after about 52 seconds, it seems to give up and decide it's time to try again -- which actually disconnects me.

Even after about two years of this I haven't found a consistent way of handling the problem other than rebooting the Macbook altogether. I find it'll connect eventually even if I don't. Turning Wi-Fi off and on may or may not help, but that may be my imagination.

I'd love to find a solution to this problem that doesn't involve rebooting, for obvious reasons. It's just not sustainable, because sometimes the computer will idle-to-suspend and then lose the connection again, which requires another reboot.

I'm using OS X version 10.8.4.

What OS X version are you running? –  Dave Sep 10 '13 at 15:26
    
Oops, thanks. It's 10.8.4. I added it to the question. –  mohawkjohn Sep 10 '13 at 15:47
    
Why would you loose the connection? is it a week signal ? or is there a limit imposed how long you can use it? –  Buscar웃 Sep 10 '13 at 17:24
    
I have no idea why suspending would cause me to lose the connection. Doesn't the OS reinitialize network interfaces when it wakes up? I'd assume so. There's no time limit imposed. –  mohawkjohn Sep 10 '13 at 17:45
    
Actually, in my experience, suspending my device requires me to re-establish my connection quite often. I don't think that's out of the ordinary, but I could be wrong. –  Dave Sep 11 '13 at 14:11
