Topic: connecting to wifi network that requires username and password

I would like to use my chumby 8 where I work.
The wifi network there requires a username and password (which I know).
I have seen some hacks that imply that a Chumby can be made to connect to such a network.
The explaination of the hacks is way beyond my understanding.
Can anyone provide instructions for a novice with basic computer knowledge and many years of computer use?
I won't necessarily understand everything, but I can follow simplified instructions very well.
Thanks.
