The Distance Dilemma

Your router's location affects signal strength more than any other factor. Every wall between you and your router can reduce signal strength. Moving your router 10 feet closer to where you use devices most can improve your connection speed.
Avoid closets, basements, or corners - your router needs open space to broadcast effectively. Move your router to a central, elevated location at least 5 feet off the ground. Expect speeds to improve within 30 seconds. For multi-story homes, try placing it near the ceiling of the first floor or close to the center of the middle floor for best coverage
