September 10th, 2012Top StoryFive Free Ways to Boost Your Wi-Fi SignalBy Andrew Tarantola
Center the SignalWireless routers act as omni-directional transceivers, shuttling data between your devices and the wired modem. As such, routers pump out signal in all directions at once, like a bubble of connectivity. However, the effective range of that bubble is not absolute—walls, floors, furniture, mirrors and metal objects can all cause interference and signal degradation. For example, placing a router near an exterior wall can cut its output in half since 50 percent of the signal is being pushed outside your home. Your neighbors may appreciate it, but your torrents won't. Instead, position the router in the center-most room of your house as high up as you can to maximize its effective radius. Focus, with BeerYou can't increase the power output (and thus the signal strength) on most wireless routers, but you can use what you have more efficiently. Some metals reflect Wi-Fi signals, disrupting the path of a wireless network using an omni-directional antennas. You can harness that same property to focus the signal from an omni-directional antenna to aim it toward your computer or couch. You sacrifice area coverage, but you can boost the relative signal strength. All it takes is an empty beer can—okay, so not totally free, but whatever. Buy yourself a beer.
Change the ChannelAll wireless routers operate within the confines of the 802.11 standard and transmit at the 2.4GHz wavelength (though newer 802.11n models can work on the 5GHz band as well). The problem is so do a lot of other devices—Bluetooth headsets, cordless phones, baby monitors, microwaves, and other Wi-Fi networks all crowd the 2.4 GHz band. With all these devices jockeying for a finite amount of spectrum, the result is often interference and reduced bandwidth. So rather than forcing devices to compete over the full length of the spectrum, the 2.4GHz band is divided into 13 distinct channels just as radio stations are. But, like a half-tuned radio, adjacent channels can "bleed" into neighboring frequencies. To avoid this, you'll want to set your router to channel 1, 6, or 11 (or 1, 5, 9, or 13 if you live outside the US). To help everyone get better coverage, coordinate with your neighbors to make sure their routers are set to another channel. Moving the router away from other 2.4GHz devices should help as well. Repeat, RepeatEven with a High Life high-gain antenna reflector attached, a single router may not be powerful enough to cover your entire house. In that case, you'll need to employ a second router as an access point to extend the network's range. If you have a spare router handy, you're set. Simply plug the secondary router into the main router's LAN port and run its setup utility. Assign the same addressing info—netmask, gateway, and SSID—to the secondary router as the primary and turn off the secondary's DHCP. Then, station the access point as far away from the main router as you can, wherever the Wi-Fi signal is weakest. Update the FirmwarePerhaps the easiest way to improve your router's performance is by ensuring that its firmware and driver are up to date. Check the device manufacturer's website regularly for these updates to keep your router in peak operating condition.
