connecting to internet via ethernet problem

Okay, so I'm currently using a HP pavilion dv6915nr notebook PC that's running on windows vista. recently my area in southwestern ohio had a few day power outage, and obviously the internet also went out. I'm a student at a local university and I can connect to all the systems on my network through the ethernet cable, but Im only able to get local access, such as iTunes music sharing, etc. I know for a fact that the internet is back up here because my roomate is using it and so are a few other buddies of mine. My question is, did I accidently change a setting or what that would do this? I've spent a good 5 hours total googling and testing many different solutions without any luck. any help is appreciated!

Did you try these steps among the troubleshooting ?

if yes, does the network show as "public" or "private" ?

Yes, and right now i have it as public, but it doesnt work as private either, i've set it as both.

Disconnect any ethernet cable, and deactivate the wireless card. click -start—-all programs—-accessories—-right-click command prompt, then choose "Run as Administrator" when the window opens, maximize it, then type ROUTE PRINT >c:\RouteTable.txt (then press [enter] ) you can open notepad and goto the root directory of C: and find and open RouteTable.txt and then copy into your reply. there is probably an extra 0.0.0.0 route that needs to be deleted. you can reactivate the card.
