I had wireless difficulties at college and a woman at the IT department used the terminal and must have changed some network settings on my computer. Although I can connect to the web through an ethernet connection, my wireless no longer works and I can no longer see the icon in the upper right corner of the screen.

Is there any way to convert my network settings back to the default settings?

Your wireless device appears to be configured properly. What happens if you run
iwlist scanning

As an aside, it is helpful,for the sake of readability to wrap shell commands, outputs or code in code tags (hash/pound/# button).
