Try some of these tips for extending your wireless range and improving your wireless network performance.
1. Position your wireless router (or wireless access point) in a central location
When possible, place your wireless router in a central location in your home. If your router is against an outside wall of your home, the signal will be weak on the other side of your home. Don’t worry if you can’t move your 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 file cabinets)
Metal, 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.
