Internet

Why don't I always have wireless internet? That is a question I would like an answer to. We have a wireless router hooked up in the computer room and I usually have a pretty good signal out in the family room. For some reason I get disconnected once in awhile. It then tries to connect to my neighbors internet. I am not sure why it acts up. It is frustrating, especially when I am trying to blog or check my mail. I generally clears itself up but it is still annoying.
