The issue here is that one of the laptops in my house has a problem connecting to the internet wirelessly. sometimes it works, other times it doesn't even though the other devices continue to work properly. I have a macbook and internet with time warner. I called linksys to see if they could fix the problem but they wanted to charge me $30, which is pretty outrageous! I can't seem to figure out why the internet connection is shady. Please help any way possible and if you can, dumb it down for me. I'm not good at this stuff

Thanks in advance!
