Three factors lead to frequent disconnection of wireless network connections

Source: CCID

In most cases, frequent wireless connection disconnection is caused by improper use. It is usually manifested in faults such as weak wireless signal, difficult connection, slow communication speed, and disconnection. The reason is generally caused by the following factors.

1. Human Factors

The distance between the wireless router and the network card is too long. In this case, you can only configure an appropriate antenna.

There are obstacles between the wireless router and the network card, and sometimes lead to disconnection failures, such as the impact of complex indoor environments, walls, and furniture. Therefore, try not to use it through walls above three layers. Some users need to go upstairs and downstairs, so it is best to put the wireless router in the window.

Channels used by wireless routers also affect the wireless performance. signals from similar channels may interfere with each other. Generally, a wireless router has a fixed channel when it leaves the factory. If there are two or more wireless routers in your environment and the use effect is poor, we recommend that you change the channel of the wireless router, select the best signal.

Ii. device Factors

1. compatibility problems: this problem mainly occurs when the wireless router is not compatible with the wireless network card of other manufacturers. One scenario is that the chips used by different manufacturers and other hardware are different from the technologies used. There is also the compatibility between early products and new technologies, for example, some products are designed before the emergence of the technology, so they are not designed to take into account the widespread use of the technology, resulting in poor compatibility with the technology. We recommend that you select a strong manufacturer based on acceptable prices.

2. Product software design: if the software system is well optimized, the system will occupy less resources and spend more time processing users' needs. Because the processing speed is fast, the system cache will not overflow, resulting in the wireless router crash and wireless signal interruption.

3. Heat Dissipation problem: the wireless router has been working for a long time and fever is positive. If the heat dissipation is poor, it may easily lead to lower processing speed and unstable signal. I personally think it is better to select an iron shell wireless router.

Iii. Environmental and uncertain factors

Currently, the most popular Wireless LAN (WLAN) operating frequency is 2.4 GHz, which belongs to the category of microwave communication. The transmission feature is linear and visible, that is, visual communication and contact methods. This shows that rain, fog, walls and other obstacles can affect the transmission quality of microwave. Therefore, we should also consider these features when using wireless technology to build a network in an appropriate environment.

The wireless communication distance is related to the radiation power, antenna direction, and antenna gain. The radiation output power of a common wireless device is less than mW, and that of a wireless network adapter is generally only dozens of mW. Currently, wireless devices generally come with an omnidirectional antenna. The Omnidirectional Antenna uses the antenna as the axis and emits outward radiation in a "bagels" shape. The oriented antenna has a strong direction, there is no signal at all outside the radiation range of a small angle. A device with a detachable antenna can use an external gain antenna to increase the communication distance without increasing the radiation power of the antenna.
