Witric Power - Witricity Explained

When I leave my computer on for a bit, and aren't using the internet. Or am generally not on the computer at all, my internet will disconnect. The only way I have found to get it back is to restart it. Also my computer wont find any other internet sources. I will go and search for something for it to connect to, but it comes up with nothing even though we do have a wireless device. I have a laptop also and that works fine. It is just this computer for some reason. Things I have tried are - Unplug and replug 10 secs later. No result. Restart, result but as I put above, the problem comes back.
