How to improve your Wi-Fi

Many Wi-fi connection issues can be solved by putting your router in a better location. Ideally it should be in the middle of your home. Make sure it's not hidden in a cabinet or blocked by furniture, and place it- Put a few feet off the ground. If your router has external antennas use them. One should point vertically and the other horizontally. This well help vary the direction of the signals so they reach your devices no matter how they are set up. If you tried all these things and your Wi-Fi is still lagging, you might consider upgrading your router or you might to install powerline adapters. They extend your router signal without running wires around the house. Kits include two adapters, one that plugs into your router and another that can be set up anywhere else in the house to widen your network. For more setup tips, visit howto.cnet.com.
