Problem Description
When the AC pings the terminal, the delay is large.
When the terminal pings the AC, the delay is small.
Process Analysis
This is a normal phenomenon, which is mainly related to the sleep mechanism of the terminal network card.
For the ping message sent by the terminal actively, the terminal can ensure that it is not in the sleep state of the network card, so the response and processing of the ping message are relatively timely.
However, when pinging the terminal from the AC, it cannot be ensured that the terminal is not in sleep mode all the time, so there are occasionally 100ms delayed packets.
Solution
1. ping -m 10 xxxx[client ip address]
2.[ap-view]option keep-active enable
3.The final delay depends on how long the terminal sleeps.
