MBP 使用 WIFI 的情况下 Ping 不稳定

[MinonHeart]

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？

[iamadiggo]

你的是有 touchbar 么 我记得之前看过一个文章说 touchbar 的 mbp 跟 airplay 加一起 影响 ping 之类的。。

[MinonHeart]

@iamadiggo 有的。蓝牙、airdrop 关了也是这个样子，没什么改善
