I cant use the internet with any other user?

I am using a hp laptop, and when i log into this first user i can log on the internet and do everything. But when i log onto my own user (which is password protected btw) it says i am connected to the internet(using a linksys), i can sign on to AIM and YIM but when i try to go on a webpage it says "this page cannot be displayed" or whatever,i try some of the stuff that it says but it wont work, i put the internet sharing but still no pages appear i really need help cuz i dont like being on the other person's user when i can be on mine, so i know that on,lets say user A i can do everything and am connected to the internet, but on user B, i am connected to the internet and can sign on to AIM and YIM but no webpages come up. Can anyone help? i tried to give as much info as possible, but feel free to ask more questions to help me out. Thx :]
