我正在运行我的无线网络每隔几分钟就会断开连接，我不知道为什么。我找到了答案另一篇帖子隐藏在评论中：
来自@Pilot6
sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi disable_11n=1"
现在我的问题似乎有所好转，因为我的 wifi 不会每 5 分钟掉线一次；但是，它仍然会掉线（我必须通过单击右上角的 wifi 图标来重置连接）。所以我想知道更多关于我可以做些什么来解决我的 wifi 问题的信息，但我也想知道解决我的 wifi 问题的过程，特别是上面显示的@Pilot6 的命令。
我<<<理解"options iwlwifi disable_11n=1"作为输入传递到命令的其余部分，在这种情况下，tee我非常确定（就像管道的三通一样）将输出管道传输到文本文件/etc/modprobe.d/iwlwifi-opt.conf和stdout（因此我在屏幕上看到它）。我可以确认：
server@thinkpad:~/Desktop$ cat /etc/modprobe.d/iwlwifi-opt.conf
options iwlwifi 11n_disable=1
因此，按照真正的 *nix 方式，将一行文本放在正确的配置文件中解决了我所有的问题 ;)，但我想知道的是为什么？@Pilot6 到底是怎么知道把它放在那里的？
我知道这/etc/modeprobe.d是modprobe 的配置目录，并man modprobe告诉我们：
modprobe——在 Linux 内核中添加和删除模块
这更能解释为什么该目录中有这么多文本文件，如下所示blacklist*.conf
所以再看一下iwlwifi-opt.conf
options iwlwifi 11n_disable=1
Pilot6 似乎想说这样的话：“Linux 内核中有一个当前启用的模块正在导致问题，所以让我们禁用它”
从高层次上看这基本上正确吗？
然后，为什么这对我有用（至少在某种程度上）？ Pilot6 怎么知道要尝试这个？
