(Editor's Note: Nearly everyone uses wireless (Wi-Fi) networks these days. This article is targeted toward home users, how best to place and use wireless access points and wireless routers, but there's a lot of good information here for small business wireless systems as well.)
If your operating system ever notifies you about a weak Wi-Fi signal, it probably means that your connection isn't as fast or as reliable as it could be. Worse, you might lose your connection entirely in some parts of your home. If you want to boost the signal for your wireless network (WLAN), try some of these tips for extending your wireless range and improving your wireless network speed and performance.
1. Position your wireless router, modem router, or access point in a central location
When possible, place your wireless router, wireless modem router (a DSL or cable modem with a built-in wireless router), or wireless access point (WAP) in a central location in your home. If your wireless router, modem router, or access point is against an outside wall of your home, the signal will be weak on the other side of your home. If your router is on the first floor and your PC or laptop is on the second floor, place the router high on a shelf in the room where it is located. Don't worry if you can't move your wireless router, because there are many other ways to improve your connection.
2. Move the router off the floor and away from walls and metal objects (such as metal file cabinets)
Metal objects, walls, and floors will interfere with your router's wireless signals. The closer your router is to these obstructions, the more severe the interference, and the weaker your connection will be.
