Fast science and technology news on December 4, today China Telecom official WeChat Science Popularization said:Slow speed, weak signal, Wi-Fi always disconnected? It may be the router & ldquo;Wi-Fi dual-band in one & rdquo; is not turned off, and everyone is advised to turn it off.
Slow speed, weak signal, Wi-Fi always disconnected? It may be the router & ldquo;Wi-Fi dual-band in one & rdquo; is not turned off, and everyone is advised to turn it off.
& ldquo; double in one & rdquo; is to merge the Wi-Fi signals of 2.4GHz and 5GHz into a single network name (SSID), and the router will automatically connect to the frequency band with the best signal according to the algorithm.
In theory, this function combines the advantages of two frequency bands, not only the network speed is fast and stable, but also avoids the trouble of manually switching networks.
In fact, this function is not intelligent, and its judgment is very simple.When the 5GHz and 2.4GHz signals are full, when the 5GHz signal is not full, the 2.4GHz is preferred.
It may appear in reality.Frequent switching results in unstable signal, incompatible devices, and 2.4GHz does not automatically switch 5GHz.Wait for the situation.
China Telecom reminded: everyone should consider whether to turn off this function according to the state of their network.
