How to Boost a Wireless Signal
The strength of wireless signals vary from time to time. Weak signal strengths decrease the quality of your wireless Internet connection. Fix this problem by boosting the signal strength of the wireless device. The access point is what sends out the Wi-Fi signals to your wireless device. Wireless modems and routers are commonly used as access points.
Relocate the wireless device closer to the access point. As you get closer to the router, the signal strength improves. You can also move the router closer to wireless device to improve the signal strength.
Move the wireless device to an area that has little to no interference. Interference is caused by the refraction and reflection of radio frequency waves of buildings, trees, and other obstructions. Open and spacious fields are areas of relatively low interference.
Use a Wi-Fi antenna. Directional and omni-directional antennas are widely used to improve Wi-Fi connections. Omni-directional antennas receive equal range and gain from all directions. Directional antennas focus the gain and range from a specific direction. Directional antennas provide better range and gain at specific direction than omni-directional antennas. Use a directional antenna if you are connecting to one access point, and an omni-directional antenna if you are connecting to multiple access points.
Use a Wi-Fi signal amplifier. Signal amplifiers are used to increase the output power of wireless devices. This will improve your range and gain.
Use a wireless USB adapter. Wireless USB adapters have more output power than standards Wi-Fi cards, and they give you more range and gain.
