Still having trouble?

Sometimes the quickest way to solve a problem is disconnecting and reconnecting. Just click the wi-fi menu and Turn Wi-Fi Off. Then click it again and Turn Wi-Fi On. You might get a better signal. If you find you need to do this frequently, you might need to move closer to the router.
