As with real estate, the three most important tenets of wireless network deployment are location, location, location. I’m talking about the location of your wireless access point (AP), of course.
In most cases, your wireless AP and your router are one in the same piece of equipment. To get the best results, set up your wireless AP in a location that’s as close to the center of your home as it can be. Placing the wireless AP on an unenclosed shelf instead of putting it on the floor will also extend its range. This is especially important if you live in a multi-floor dwelling.
The fewer walls, floors, and other obstacles between it and your client devices the better, so try to avoid putting your wireless AP in the basement. Obstructions such as masonry walls, large appliances (your refrigerator), and metal file cabinets will all impinge on your wireless AP’s range.
