Wireless Device security Settings detailed

Wireless router, AP and wireless network card are the representative of wireless products, has gradually broken the home and SME market hub and ordinary routers "eminence" situation, become the first choice for the construction of Soho and small and medium-sized network. The market demand is huge, the price is sensitive, the competition of the similar product is intense, all requests the wireless product manufacturer must try all means to depress the cost, and some small and medium-sized enterprises are "beggars" in order to reduce the cost. Some fake and shoddy products of the emergence of the consumer caused by the trouble and problems are as follows:

Crash

I am afraid that the most powerful problem for consumers of wireless products is that wireless products suddenly stop working and crash. Especially when the novice first use the wireless router, this problem is more common, the general reason is that configuration problems, in the repeated selection of appropriate options can generally be resolved. But some users reflect, wireless products are always gesanchaiwu, and wireless products after-sales service personnel also have no good way to solve, but is repeatedly told the user to upgrade the software version to the latest, or simply said that the hardware design problems.

Short effective distance

The problem has become so common that the actual effective distance of a wireless product can reach its claimed maximum distance of 1/3~1/2 even if it's not bad. The emergence of this problem has many factors, such as the effectiveness of wireless antenna, wireless product location, wireless products between the obstacles, wireless products, such as the cooling effect, these will become wireless products manufacturers to shirk its product quality excuses. In this case, to achieve the goal of increasing the transmission distance, we can take a reasonable position to choose the location of the wireless antenna, wireless products to increase the gain antenna and so on. If you are interested, you can also do a simple gain antenna, perhaps the gain effect can make you very satisfied.

Frequent disconnection

Many friends in the use of wireless products, often found that wireless signal suddenly strong and weak, suddenly broken, in addition to environmental impact and electromagnetic interference factors, mainly by the wireless product itself, the stability and quality of the cause. For example, when using a wireless router, although the network connection is still "alive", but has been unable to access the Internet, and restart the router, you can return to normal, this situation is a typical wireless product instability caused.

Call the manufacturer's after-sales service phone to inquire, it is possible to get two answers, one is to say with the wireless network card compatibility problem, one is said to upgrade the software version, it is not clear, said this is a special case, in short to admit that their products have problems of almost no manufacturers.

The choice of wireless products also hope that you pay more attention in the purchase, do not map a small amount of interest to bring their own greater trouble.

The problems with wireless devices are as follows:

Compatibility difference

We often encounter such a situation, the wireless product instructions clearly tell consumers that their products compatible with certain technology products, but in the actual use is not the case. Wireless security compatibility difference is mainly manifested in a manufacturer's wireless router or wireless AP and another manufacturer of wireless network card connection work is not compatible.

The reason for incompatibility is that different manufacturers use chips and other hardware and the use of technology is different, or the early product and the new application of new products compatibility between the bad, for example, some wireless products are in the Centrino technology before the advent of the design, in the design is not considered the Centrino will be so common use, This can lead to poor compatibility with Centrino. Compatibility issues can lead directly to the inability of the wireless product to connect, or to a poor connection speed.

Poor interference resistance

With the daily use of the gradual increase in electronic products, and wireless products using the same frequency band of products are more and more, which greatly affected the wireless router and wireless network card transfer between the speed of transmission, which on the wireless product anti-jamming has put forward higher requirements.

Interference mainly from two aspects, first of all from the vicinity of the same band of wireless equipment interference, with the wireless market development and wireless products use density is increasing, the problem in companies, office buildings, commercial areas, residential area are very easy to happen.

In addition, other sources of interference will also have a greater impact on the wireless router antenna transceiver effect, such as cordless phone (2.4 or 5.xGHz), Bluetooth equipment (2.4GHz), pulse radar (5.4GHZ), microwave ovens (in the 2.4GHz bandwidth of 50% of the busy will produce pulse interference), Low-energy RF light source (2.4GHz) and so on. Some wireless products in order to reduce manufacturing costs, anti-interference design and shielding metal materials are relatively poor, resulting in the wireless product anti-jamming is poor or there is no anti-interference.

Poor heat dissipation

Whether the wireless router or wireless network card, its chips and a variety of devices are working in a certain working environment, such as temperature has a certain range, if the temperature is too high will directly lead to the loss of work efficiency, and even lead to the damage of wireless products. Wireless products are bound to produce a certain amount of heat, so whether the timely cooling is a wireless product quality inspection of the important indicators, which with wireless product design structure, working power, cooling characteristics, heat dissipation materials are closely related.

Some wireless products because of the one-sided pursuit of beauty and low-cost, and a large number of poor heat dissipation materials and structures, which will lead to long-term work of wireless products overheating, thus affecting the connection speed, and even damage the hardware.

Wireless network card work is not as long as the normal installation on the PC can be, to fully consider with the wireless router or AP compatibility and coordination, otherwise it will affect the wireless transmission distance and efficiency, so do not just test in the notebook computer can be normal installation and use, and the key to see whether the wireless equipment with good.

About the selection of wireless devices, the above related content has to wireless security should master three of the best skills introduced, hope you can have some harvest.
