Boosting the Signal
Not all routers are created equally. Some can send a strong and steady signal far and wide. Others have a signal which fades out after 30 feet or so. This becomes an issue when you use your wireless device all over the house.
In positioning your router as in real estate, it's all about location. You'll want to have the router in as open area as possible, away from as many obstructions as possible. Keeping the router in a closet or behind any other closed door will weaken the signal. If you live in a two- or three-story house, put your router somewhere on the second or third floor. If you live in a bungalow, apartment, or condo, try putting the router on top of a bookshelf. I know of at least two people who have actually put their routers in their ceilings. Once you get over seeing a pair of antennae sticking out like fangs, you realize the boost you can get.
Also, keep the router at least two or three yards away from such electronic devices as computer monitors, microwaves, or a cordless phone. These devices pump out radio waves that can interfere with the signal from a wireless router, and the closer the router is to them then the greater the interference.
