These router phenomena must have troubled you. Take a look and learn more

Does the row of indicator lights on your router often cause you confusion? Why are some always on while others flicker? How does WIFI work? Today I would like to share with you some common knowledge about routers. I believe you must have had questions about these in your life.

The most important thing is the flashing indicator lights on the router. Taking a dual-band wireless router as an example, there are usually 7-9 indicator lights, which are the power indicator light, system indicator light, 2.4GHz wireless network indicator light, 5GHz wireless network indicator light, WAN port indicator light and LAN port indicator light.

After the power is turned on, some of them remain on, while others continue to flash. First, you will see that the first indicator light is marked with the word "PWR", which is the abbreviation of "POWER". It is the power indicator light and will remain on. The next "SYS" stands for "system". When this indicator light is on, it means that the system of the wireless router is running. When there is data transmission, it will flash continuously. The next word "WAN" indicates that this is the network interface of the external network. If this interface does not keep flashing, it means that there is a problem with the user's external network. The following three indicator lights "LAN" are three internal network indicators. When the network cable is connected to the LAN port and the device, the indicator lights will light up. In the stable state, it will remain on. If it keeps flashing, it means that there is a problem with the connection. The last two indicator lights are marked "2.4GHz" and "5GHz". These two are indicators representing wireless signals. When the wireless connection is normal, they will switch between long light and flashing, which means that the wireless router is continuously sending data through the wireless network.

Generally, when you cannot access the Internet by connecting to WiFi, you can check whether the indicator light of the WAN port is normal to troubleshoot the problem. If you cannot search for WiFi, you can observe whether the indicator light of the wireless network is normal. If it is not lit, then there must be something wrong with the router.

Secondly, let's learn about how WIFI works. WiFi sends data to wireless routers via radio waves. The transmitted data will be divided into individual data packets and then integrated together. The packet loss we often hear about is the loss of data during the transmission process, resulting in incomplete information. The same radio waves, why can WiFi watch videos, but mobile phones can only talk to each other? This is caused by the frequency of radio waves. Generally, our WiFi works in the 2.4GHz or 5GHz band, and the working frequency of mobile phones is around 800-1GHz. The higher the frequency band of the radio, the more data it can carry, but it also means that its penetration will become worse. Just like the signal of 5GHz WiFi after passing through the wall will be much worse than that of 2.4GHz.

The third point is why we need to restart the router from time to time. Because the wireless router is like a small computer, it also has a CPU, memory and operating system. After the wireless router is restarted, the original memory will be cleared and the system will restart, which will make us feel faster when using it. ??After the restart, the original network request has been cleared and the router will be revived immediately. If you think it is troublesome to restart the wireless router manually, you can look for the "scheduled restart" function in the router system settings. Choose to restart the router automatically at a fixed time, such as late at night or during the day when you are at work and don't need the Internet at home. Or consider installing a smart socket, plug the power supply of the router into the smart socket, and set the time for the smart socket to automatically power off. This can also achieve the effect of restarting the wireless router.

Hopefully, the above three bits of common sense can solve some of the confusion in your life and help you get a smoother network.
