About Wi-Fi Signal Boosters

By Russell Huebsch

Wi-Fi networks communicate via radio frequencies, so they are prone to interference from walls and other radio signals. A Wi-Fi signal booster increases the power of a network without cables or extra wiring.

Function

Wi-Fi signal boosters are also called repeaters. This product receives the signal from your wireless router, amplifies it and sends it back out, according to High Speed Internet Access Guide.

Benefits

For a regular router, you can just purchase longer wire. Wireless networks are prone to interference from walls and furniture as the Wi-Fi "bubble" expands. A repeater can boost your signal strength up to three times and even pick up signals outside of your wireless network.

Tip

Linksys and D-Link are the major producers of repeaters in the U.S., and you can get one for $50 to $100, according to High Speed Internet Access Guide. Computer expert Bob Rankin suggests an Airport Express for Apple users.
