There is no signal, the network does not cover here, often heard wireless network users complained that the wireless connection signal is too weak, sometimes even affect the normal network connection. So what do we do when the wireless network signal is too weak? Here's how to teach you four strokes to solve the problem of wireless network signal too weak.
First trick: Clean up roadblocks
to minimize obstructions in transmission lines. Since wireless signals are transmitted in a straight line, the signal strength of wireless communication will be weakened if obstacles are encountered during transmission. In particular, the attenuation of the wireless signal is very large after passing through the metal barrier.
Experiments have shown that, within a distance of 10 meters, the wireless signal through the two block brick wall, can still achieve the nominal maximum transmission rate, but after a layer of floor slab, transmission rate will be only half the nominal rate. This shows that the reinforced concrete wall experience greatly weaken the wireless signal, the rational placement of wireless routers (or wireless AP) has become an important factor affecting the strength of the wireless signal.
When setting up a wireless network, it is ideal to place a wireless router at the intersection of several rooms. Little fat puts the wireless router at the intersection of several offices, although the maximum wireless signal strength in the office is only about 70%, but this does not affect the normal network connection.
Hint: The wireless signal strength, can use the network Stumbler and so on software to carry on the view, does not make the detailed introduction in this.
Second trick: refuse to "harass"
to pay attention to reducing interference. Like all wireless communications, wireless networks are also subject to interference from other electromagnetic waves. Because the IEEE 802.11b/g standard working frequency band is 2.4GHz, and many industrial equipment also works in this frequency band, so the wireless network is "harassed" the "opportunity" many.
If there is a strong magnetic field nearby, the wireless network will certainly be affected. For example, some users put a wireless router near the microwave, and found that when the microwave oven work, the wireless network will appear inexplicable network failure, and the microwave after the network back to normal.
Small fat found a lot of colleagues in the use of walkie-talkie, and in the intercom "harassment", the wireless network will naturally be affected. Therefore, it is also necessary to keep the "purity" of the wireless network environment as much as possible. Xiao Fat reminds everyone to try not to use the walkie-talkie in the wireless network.
The third trick is to change the "road" to go
to try to change the channel of the wireless access point. If tested, the signal is weak, but the wireless access point has not been moved or changed recently, you can try to change the wireless access point channel to see whether the signal can be enhanced. Channel changes can be made in the Settings window of the wireless access point (wireless router).
Fourth recruit: Request support
If the wireless router (or wireless AP) you purchased uses a removable antenna, in case of weak signal, consider removing the original antenna of the device and assembling a wireless gain antenna (Figure 2) to enhance the signal, which is cheaper.
in general, when long-distance data transmission is required to ensure the strength of the signal, an antenna with a large gain value should be selected, and for a wireless network with a shorter transmission distance, the antenna with a small gain value can be selected.
A few of these solutions for small fat use only need to adjust the device location, pay attention to the network environment, set the network parameters, buy the antenna can be implemented smoothly, is very suitable for some unwilling to large-scale upgrade wireless network equipment units. For some of the higher network requirements of enterprises, the best way is to buy powerful, wireless network signal coverage of a wide range of wireless devices to build a wireless network.
