Reasons for frequent disconnection of wireless networks

one, human factors

The distance between the wireless router and the network card is too long, in this case can only be solved by a different configuration of the appropriate antenna.

The wireless router and the network card have the obstacle influence, sometimes also can cause the disconnection breakdown, for instance the indoor complex environment, the wall, the furniture influence. So try not to go through walls over three floors as much as possible. Some users need to use upstairs downstairs, preferably the wireless router in the window.

The wireless router uses the channel, also affects the wireless effect one reason, the similar channel signal can interfere with each other. The general wireless router factory has a fixed channel, if you use the environment with two or more than two wireless routers, and the use of bad, recommended to change the wireless router channel, choose a signal the best.

Second, equipment factors

1, the compatibility of the problem: the main focus on the wireless router and other manufacturers of the wireless card is not compatible when connected. One situation is that different manufacturers use a number of chips and other hardware and the use of technology are different; there is also the compatibility of early products with new technologies, such as the design of some products before the advent of Centrino technology, which is not considered to be so common in the design, resulting in a poor compatibility with Centrino. It is recommended to choose the strong manufacturer's products on the basis of acceptable price.

2, product software design: Software system optimization is better, the system will occupy less resources, more time is used to deal with the needs of users. Because the processing speed is fast, therefore does not cause the system cache overflow, causes the wireless router to panic, the wireless signal interrupts.

3, the thermal problem: wireless router for a long time to work, fever is certain, if the heat dissipation is bad, easy to reduce the processing speed, resulting in signal instability. I think the wireless router that chooses the iron shell has better effect.

Iii. Environmental factors and uncertainties

At present, the popular wireless local area network (WLAN) operating frequency is generally 2.4GHz, is a microwave communication category. The transmission characteristic is the linear type, the visible type, namely the visual range communication contact way. This shows that rain, fog, wall and other obstacles can affect the transmission quality of the microwave. So we should take these characteristics into account when we use wireless technology, and build the network in the right environment.

The distance of the

Wireless communication is related to the radiated power, the direction of the antenna, and the antenna gain. The common wireless equipment radiation output power below 200mW, the wireless card power generally only dozens of MW. At present, the wireless devices are generally equipped with omni-direction antennas, the omni-directional antenna Radio wave takes the antenna as the axis, appears "The Bread circle" the outward radiation, the directional antenna has the extremely strong directional direction, is completely without the signal outside the small angle radiation range; The device using the removable antenna can add an external gain antenna, The communication distance can be increased without increasing the radiated power of the antenna.
