Hi, my computer has been messed up for a while now. It connects to the internet, but when I try to get on things like Safari and other stuff that uses Internet/wifi, it doesn't let me on, and gives me the good ol' "Safari can't open the page" message. I've tried network diagnostics, and it said I was connected to the Internet, but then my hopes were crushed when it didn't let me on the internet. I've tried Airport Utility, and it had a green "connected" dot, but my hopes were shattered again. I tried Disk utility, did all the proper procedures, but that failed me also.
RECAP: My MacBook Pro says it's connected to the Internet AND WiFi, but it doesn't let me use Safari/any other things that use Internet/wifi. Any help would be great. Thank you!

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
If using Wifi/Airport...
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
(There may be better or faster DNS numbers in your area, but these should be a good test).
