When using a MacBook to ping a packet, it often takes around 3 to 4 packets per 10 or so, and the delay time is about 1000 milliseconds.
The use of other people's computer ping package is not a problem, the computer restarts have had a period of time.

Networkinterfaces.plist, Com.apple.wifi.message-tracer.plist, and com.apple.airport.preferences.plist are removed or removed.
