为什么我的 MacBook Pro 通过 Wi-Fi ping 时间很长？

Question

我在连接 Wi-Fi 时遇到问题。奇怪的是，对路由器（<30 英尺远）的 ping 时间似乎激增，通常会超过 10 秒，然后才慢慢回落。你可以看到下面的趋势。我在 MacBook Pro 上完成了正常的工作（重置 PRAM 和SMC、更改无线频道等）。它发生在不同的路由器上，所以我认为它一定是我的笔记本电脑，但我不知道它可能是什么。

该RSSI围绕-57值悬停，但我看到0，48和54所述的信号强度为〜60％9％噪声之间的传输速率翻转。目前，范围内还有 17 个其他无线网络，但在同一频道中只有一个。

1 - 我怎样才能弄清楚发生了什么？
2 - 我该如何纠正这种情况？

Answer 1

在早期的 Mac 笔记本电脑中，很容易获得 wifi 卡（就在易于打开的键盘下方），我不知道这是否仍然如此。

如果是，我建议拔下并重新插入该卡的连接器。在过去的几年里，其他人也遇到过类似的问题，但通过重新安装该连接器可以解决。
