5 easy hacks for your PC and Wi-Fi network

Speed up your CPU and graphics card, add advanced features to your wireless router, boost your network's range, and tweak your PC's power consumption for extra efficiency.

Hacking isn't just for geeks anymore. In this era of ubiquitous gadgetry and free information, anyone with a screwdriver can do a little unauthorized tinkering. Sure, the word hacking has negative connotations. But hacking is really about being a do-it-yourselfer. That means opening a Web browser rather than your wallet to get more functionality from the products you own.

Without spending a dime, you can boost your processor's speed, give your graphics card a performance boost, increase your Wi-Fi range, or add sophisticated features to your old router. You can even beat the rising cost of energy by underclocking your CPU to a more modest, power-saving level.
