My internet has slowed down somehow. It used to top out at 60-70 KB's/Sec. Now it tops out at 30 KB's/Sec. Could this be a virus? I am on airport but when I got on direct connect it did the same thing. Any ideas?
Perhaps you are further from the airport base station. If you are at the outer limits of connectivity, you might receive at lower rates. Try moving closer to the station and see if speed correlates to your location.
