OSX cannot connect to internet, but Win7 can

[Fritzy]

So I'm at my dad's house for awhile and he doesn't have a wireless network, but has cat5e running in the walls so normally I can get a connection to the web with an Ethernet. I've run into a problem where I cannot connect to the internet with a direct connection while on OSX, but in my network pref it's giving me an ip address, and in a browser I can connect to the router.

When I bootcamp to Win7 I can connect to the internet just fine, and for a the first couple of days I could connect to the internet on OSX.

Since I'm traveling I can't restore a backup, or a clean reinstall.

Check what your DNS server addresses are in your Network Prefs in OS X. Try deleting them and setting it to the IP of the router.
