Butterfly, I would go speak to your IT department. If IM is blocked when you are physically connected to your network at work, then more than likely, even if they have wireless in your office, you will be blocked on that route as well.
Another reason for checking with your IT department first is the fact that most network admins do not appreciate an individual placing a personally owned laptop on their network. If your notebook is infected w/ adware/spyware/virus, it can cause havoc and possibly get you repremanded (although, if it did cause damage, one could make the argument that they should only be blaming themselves for not locking things down).
