Frankly speaking, the average latency of a WiFi network is far more than the wired network. Generally, wired network is less than 1 ms, while WiFi network is 1–3ms, which is 10–100 times of the former;

Why? Because the WiFi network need go through the operation of encryption and decryption which takes a lot of time. In contrast, wired network only need hardware operation and transmission so that its latency is quite small;

Last but not least, for WiFi network, the keypoint is NETWORK SIGNAL. The higher the network signal, the lower the ping is. That’s to say, the network speed is mainly depends on its signal quality.
