Too much power. I noticed that whenever I sat within 5-8 feet of my WIFI router, my SP would show 5 bars but refuse to connect or provide only a limited connection. As a test I moved my router to the next room over and bingo, instant connects and fast web page loads. Then as a further test, I bumped the transmission power of my router up to 256 from its default of 71. Again, even though my router was in the next room, I could no longer connect reliably. Back to 71 and perfect connection. So it would seem our Marvell WIFI receiver in our SP's suffers from too much of a good thing. Too much power or too close to the router and it freaks out. My PC loves the extra power, my SP not so much. So, if you are having wifi problems at home with your SP, try moving your router OUT of the room in which you usually use your SP. In addition, if your router's firmware allows you to pump up the transmission power, put it back to 71 (default) and you will probably have a better experience.
