When WeChat connected to wifi, someone sent me a message without prompting me to open my mobile network.

The weak wifi signal caused the network delay, so I couldn't receive the prompt at that time.

Weak wifi signal will affect our internet access speed and delay our sending and receiving messages. The other party sends us a message, and we may receive it in a few minutes, and the message prompt will be delayed.

Wifi is a kind of wireless network, and the signal of wireless network is weak, so the obstacles in transmission lines should be reduced as much as possible. Because wireless signals travel in a straight line, the signal strength of wireless communication will be weakened if obstacles are encountered in the transmission process. Especially after passing through metal obstacles, the attenuation amplitude of wireless signals is very large.
