If you just moved and didn't change your settings on your router, you could have interference with another wireless network. First, I would change what channel your router is on, (there should be 11) and see which one you get the best performance on. You could go to www.speedtest.net to see how your connection is. Moreover, a hacker group has been attacking Sony and I've been having connection issues all weekend. Finally, if you are getting a 95% signal you could of bought a crappy dsl connection.
