[MacBook Pro] MBP 使用 WIFI 的情况下 Ping 不稳定


周围环境

  • MBP 距离 AP 有 6m 左右的样子,中间有一堵墙
  • 周围约有 20 多个 WIFI

MBP Ping

MBP 连接电源+USB-C 连接一台显示器。

很不稳定,Surge 偶尔会提示网络已恢复。访问网站,有时候感觉比较慢。

PC Ping

有台 PC ,也是连接相同的 WIFI ,环境相同,就是距离稍微远一点点。100 次 Ping 的结果大部分 1 ~ 2ms ,最大不超过 5ms 。

疑问

  1. 大家的 MBP+WIFI ,Ping 值大概是多少?
  2. MBP 的 WIFI 是不是没救了?
