Improving Your WiFi Antenna Performance
Cutting The InterferenceSometimes your WiFi antenna is working just find, but the airwaves are crowded with other wireless signals, whether itís from your phones or from neighbors using their own wireless connections. If youíre having trouble, try reconfiguring your WiFi antenna to receive information on a different channel than the one youíre using. Changing to one of the other of the eleven channels you have available is a simple way to try to improve the performance of your WiFi without making further changes.
Getting A Stronger AntennaAnother solution, if simply changing channels doesnít work, is to use an external WiFi antenna, that is, one not encased in your computer housing, to transmit data. External antennas are usually capable of putting out greater power when transmitting, and since wireless performance is linked to the strength of the signal, changing to a stronger, external WiFi antenna can be a big help. There are solutions that exist, from ready-made to projects that you do yourself.
Directional AntennasOne problem with an external WiFi antenna is that you can actually make your network less secure, by making it easier for people outside your home to access your network due to the stronger signal. This is mostly a problem if you purchase what is known as an omnidirectional WiFi antenna, which radiates its signal equally in a sort of donut, with the center of that donut located where the antenna is. But there are solutions to this, requiring a different sort of antenna.
In contract to omnidirectional antennas, directional WiFi antennas focus the signal and point it in a particular direction, meaning that you need to aim the antenna at the part of your home where youíre trying to get a signal. While this might seem like an inconvenience, because the signal is strongest only in one direction, people not along that line, people outside your home, for example, wonít receive a strong signal, which makes this a more secure solution. But however you choose to approach the solution, you should be able to find a way to ease your WiFi antenna woes.
