Hey! Cool that you're using my site to get help.
Anyone that doesn't know already, Christian is my Son. He lives with his Mother in Texas and floats between there and Phoenix.
I wish you just lived down the street and I could just come over and help.

--- what kind of signal strength does your air card show?

(you obviously already know where this is but other people reading this in the future may not)If it's really weak then you might benefit from an external wireless adapter that has a better antenna. The best thing to do in my opinion would be to move the router and modem in your room (if possible) and hook up via ethernet straight to the router. You could still go wifi and being closer will help but if your computer is stationary anyways and the router is close enough you might as well get the better connection through ethernet.
Do you know what speed your supposed to get on your connection? When you get a chance take some tests from your Mom's computer or move the macbook closer to the modem/router and see what you get.
To keep track of which tests are which I recommend using identifiers, this is exactly the situation that feature was originally designed for.
... we'll get you fixed up
