INTERNET stopped working

Hi, I've tried all the fixes I can find for this and nothing has worked. Safari, Firefox and Software Update have all stopped functioning, anything involving the internet won't load up. But when I check the network connection it says it's working properly. This started overnight, and wasn't after downloading an update or installing any new software. I've used the 'terminal' app to ping websites and I get a response in about .38 of a second. It is a wired Ethernet connection, with roughly 35mbs download and 15mgps upload speeds. Any ideas? Thanks.
