Guys, I need help. At work our Internet is blocked. Now, today I decided to bring my usb wifi adapter. I found a wifi network which allows me to browse the web - at least I got to google (haven't checked much further).

Now, with this connected I can't access the address where I need to do work on, and
nd my email doesn't connect etc. Obviously the wifi connection is making the pc not access the network connection or something. Anyway I can get this wireless connection working where it doesn't interfere with the work's connections? Please help!
