几天以来，我的笔记本电脑上的连接速度非常慢，但在所有其他设备（手机、平板电脑、公寓中其他人的电脑）上，连接速度非常快，例如在我的手机上，我达到了 62Mbps在 wifi 上进行速度测试，而我的电脑甚至无法开始测试...
我感觉需要时间的是第一次连接：比如我可以流畅地播放一个视频，但视频可能需要40秒才能启动。仅在 Google 上进行简单搜索可能会超时、需要多次刷新或需要 40 秒才能完成。
我感觉其他地方（在我的工作场所）的连接速度也较慢，即使我使用以太网，但也稍微好一些。
即使 ping make 也需要 20 秒到 40 秒才能启动（然后它就能流畅地工作），请参见此 gif，它显示了 ping 的连接：
我认为有时我什至没有连接到 wifi，但连接可能会超时，而 ping 可能工作正常。例如，我尝试手动连接到各种 DNS 服务器，有时连接有效，有时超时，但 ping 可能同时有效：
通常，如果我尝试curl联系网站，第一次尝试超时，然后我设法在 10 到 40 秒内到达该网站，然后接下来的尝试几乎是瞬时的：

我还尝试启动另一个系统（xubuntu 20.04），它同样很慢，所以我想这并不是我自己的配置所特有的东西（我正在运行 NixOs 不稳定）。另一方面，如果我连接到配置为热点的手机，速度很快，所以问题似乎不是我的硬件......此外，我在以太网上遇到了类似的慢速互联网（在我的工作中）。
另请注意，我预计 ping 在速度超慢时会丢失许多数据包，但实际上它不会丢弃任何数据包……每个数据包都相当快地获得（显然是 10 毫秒），但随后它会等待 5 秒才能发送下一个数据包（而不是 1 秒）：
（注意这个例子中第一行是直接出现的（可能是被缓存了），有时也需要几秒钟才出现）
有些人问我关于我的resolve.conf，所以这是我使用以太网时工作中的一个（我8.8.8.8通过网络管理器添加作为 DNS 服务器以尝试提高速度，但似乎并没有更好），我也可以发送今天晚些时候在家：
$ cat /etc/resolv.conf
# Generated by resolvconf
search wlan.MYLAB.nl
nameserver 8.8.8.8
nameserver 192.168.1.1
options edns0

你也许可以从你的 Wifi 卡上获取信息，ethtool -i DEV_NAME对我来说是这样ethtool -i wlan0。您还可以运行man ethtool查看所有其他选项，例如驱动程序、测试等等。它基本上允许您选择/设置下面的所有选项高级无线选项，那么特性如果您使用的是 Windows，则查看您的 wifi 卡。
