Wi-Fi wireless transmission speed depends on placement

Many people are concerned about Wi-Fi wireless transmission speed, in addition to the hardware itself adjustment, placement is also a very important factor. With some very basic techniques (how to place routers and how to configure them) and some of the more sophisticated techniques (with dedicated equipment, etc.), you can carve out a new world for your wireless router. After spending several hours optimizing a home network, the effect is obvious, indoor wireless transmission distance increased by more than 1 time times-from 30 meters up to 60 meters (in the backyard and increased by more than 40 meters), while the performance increased by 15 times times. And it all happened on a two-year old 802.11g wireless router.

Place, to see the position

First, the location and placement of routers is the most basic (and most overlooked) two ways to build efficient wireless networks. Most people put routers in the first place they think, which is a big mistake.

You can imagine the wireless router as the center of the sphere, and the network connection extends from its antenna to all directions. My advice is to place the router as close to the physical center of the home or office that must be covered. Start with a building plan or sketch and draw a diagonal line from every corner to determine the center position.

Of course, some people cannot adopt this proposal. Perhaps the center of the building is a wall of stone or a brick chimney, or a network cable can be introduced into a building from the worst possible location. If for some reason, you can't put the antenna in the ideal central position, please do not be disappointed, we will also introduce other solutions.

Now, please look around and find a good home for the router. Avoiding the corners (especially in the old house) is the first step, because the corners will weaken the signal as the signal passes through. In addition, do not put the router in the closet, bookcases or entertainment center is a good place to place the router inconspicuous.

Of course, the wireless router requires an AC outlet and a connection to your cable or DSL data source. If the building's DSL or cable modem lines are in an inconvenient position, please don't panic, you can use directional antennas (we'll mention the next serial article), or extend your DSL and cable lines.

If you choose the latter, you will find that the wall-broken wiring is a laborious and costly project to keep your router in the right place and can cause damage. As an alternative, consider using a thin coaxial cable or an ethernet cable, which can easily be inserted into a wall by a cable wrapped in tape. After you lead the cable to the desired position, apply a thin layer of adhesive or plaster, then paint, and it will be your little secret. The length of this cable is 3~5 meters, the cost of the entire project should be between 80 to 120 dollars.

Configuration, heavy in detail

Wi-Fi wireless transmission, when everything is placed in place, connect the router power supply, enter your security settings. The next thing to do, is to adjust the router to the maximum rate of operation. Many routers are set to run at a 75% rate or are automatically adjusted, and I find it best to adjust the signal rate to as large as possible.

The router is then set to use only one 802.11 protocol, because mixing mode (most Wi-Fi devices are available for 802.11a/b/g, or even 802.11n clients) lowers the data rate. By using only 802.11g clients, you can increase the performance of the router nearly one times, up from 1Mbps to 2Mbps at a distance of 20 meters. Of course, you must make sure that all connected devices are set to use the protocol you have chosen. If they don't all support the agreement you choose, you either have to give up the proposal or pay to buy new equipment.
