Connected to internet but cant browse

Seeing what you guys tried all so far, my money would be on the router blocking access for some reason. From your ipconfig snip I see the router connects you and gives you an ip as well as a DNS address. That means, locally the connection works. But somehow it seems that the router blocks you from connecting to the outside world.
Check the settings (especially if the amount of supported computers is set too low or if the router firewall has any limitation rules that concern/include your computer)

Try Punksters suggestion first and see if that solves it.
To check "inside" the router you need to connect to the router control panel by typing

http://192.168.1.1

in the browser URL.
But if you have to ask, you haven't been in there to change anything. Is there anybody else who might have set up the router and probably mis-configured it in the process?

well you should ideally do that from one of the working computers

Somebody must have set up all those computers in the router. That person must have also set up security
(hopefully).
Obviously it wasn't you so I don't suggest you go ahead and click around there in the settings or chances are none of your computers connect to the internet after that What make and model is your router?

waeough said:

haha. good point..

it asked for a password and such. and i dont have the user name

default router username is just left blank
default router password is usually admin

try that and see if it works

if not then contact whoever set it up for you
