Without knowing more about your setup and theirs it is impossible to say. Best course of action would be to contact the people that gave you the user name and password and ask them. They could be doing MAC authentication as part of their login system, or maybe your username and password is only valid on the part of the network your computer is attached to, or any number of other possibilities.

indeed a logic answer
thanks very much
