For some reason every time i use the command airodump-ng mon0 it only shows my own network. All the videos I have seen, the command shows multiple other nearby networks. How come I am having this issue?

I was going to take a screen shot and post it, but for some reason I am getting an error message? (Could also use help on this lol) So here is all I am seeing.

Also can anyone explain the difference between top half and bottom half, or better yet point me towards a guide/tutorial if any that explains all the data displayed. I am not a leech or anything, I am actually really interested in learning how to use this distro entirely but its these little bumps in the road that discourage people from continuing.
