my desktop in school is connected to the room's wireless with no problem at all. When i tried to connect to another wireless (the school's main wireless network, i got the login) , it connected and signal is strong.

Howver i just can't seem to surf any website at all.

When i tried to go: Google

It'll load for a while, the the status bar turn the web address i typed to: www.www.google.com.com and still no result showed up.

Any ideas what happen? This wireless however works on my own personal laptop. Just having problem with this desktop.

This is the result of my ipconfig/all:
