How to deal with the problem of wireless routing signal instability

We all know that wireless routers can be directly connected to all Ethernet networks, or they can be accessed through LANs such as switches/hubs and broadband routers. However, our users will find that the signal is unstable when using the wireless router. Below, let's take a look at how to analyze the main points to quickly find out why.

First, the key to the problem is the wireless signal conflict, once again to a friend's home and through the Network Stumbler wireless signal scanning tool to scan the surrounding signals, the author found that there are indeed many wireless signals in the vicinity of friends It is estimated that all neighbors use wireless routers to transmit. And some of the default SSID numbers in these signals are TP-LINK, which is judged to be the product of TP-LINK, and the default values ​​are used.

Second, the strength of wireless signals is often not the main role of the transmission power of their own devices, the degree of interference between signals often plays a large role. Therefore, it is the best way to improve the signal strength by reasonably modifying the wireless signal transmission frequency band and avoiding the default frequency band as much as possible.

Third, the setting conflict caused the signal to be abnormally weak. My friend recently set up a wireless network, and the device used is a TP-LINK router. However, the actual network transmission speed is not ideal, and the signal coverage is also Very small, did not reach the ideal transmission distance, the signal strength quickly weakened after isolating a wall or a room.

Fourth, check the notebook to ensure that the wireless network card switch is turned on, but the wireless network card indicator is still not lit. Next, scan the current wireless network with other notebooks to connect smoothly. There is no problem with the hardware of the friend's notebook. The corresponding wireless network card parameters in the BIOS are also enabled. The driver of the wireless network card is repeatedly deleted and reinstalled. The system CD that comes with the system is still unable to solve the problem.

V. After investigation, it is found that even if the signal is not up to the highest level in the wireless router, it can't work in the full signal state. If you enter the wireless router setting interface, you can't find anything wrong. Take the device. I didn't find any problems after returning home. The signal was very strong. Normal wireless communication was also possible after two rooms. It seems that the device itself is not a problem.

Sixth, there is a situation in which the wireless device is equipped with a wireless network card. However, in the course of use, there is a problem that the wireless network in the home cannot be successfully connected. The specific symptom is that there is a wireless network, but Unable to search for wireless network signals, the system displays the error message "Unable to connect".

VII. Check the settings of the wireless network in the wireless router, and find that the wireless signal transmission frequency band is selected as 13 frequency bands, and the Intel wireless network card with the notebook itself has only 11 channels, which causes the Intel wireless network card to be unable to connect. The failure to the wireless router. After the modified transmission band is modified, the problem is solved.

VIII. Since TP-LINK products will transmit wireless signals through frequency band 6 by default, conflicts will occur between multiple TP-LINK products. Different network wireless signals are transmitted using frequency band 6. Mutual interference affects the strength of the wireless signal, causing the fault of the friend's own wireless signal. Finally, the author modified the wireless signal transmitted by the TP-LINK wireless router using the frequency band, and selected a frequency band that is not used by any device in the current network. All the problems were solved and the wireless signal returned to normal.

After the above eight methods to find the cause of signal instability in the wireless router, and then according to the specific situation to solve the problem, I believe that your wireless router signal instability problem will be processed faster, I hope this The tutorial is helpful to you.
