我最近在使用 ubuntu 20.04 LTS。升级到 20.10 试图修复该问题，但问题仍然存在。
我使用 LAN 电缆连接互联网，有时显示为 100mbps 局域网连接，我拔下电缆再插回去。它显示为 1000mbps，我恢复了 LAN 上的 300Mbps 上传/下载速度。这有点不方便，但我可以接受。
今天我不得不丢弃我的 LAN 电缆，我发现 Ubuntu 上的 Wi-Fi 很糟糕。
我在谷歌搜索后找到了一些答案
省电模式从 3 改为 2 - 不起作用
sudo apt purge backport-iwlwifi-dkms
但这个错误已经修复了。即使我尝试该命令，它也会说包不存在，所以无法删除
- sudo nano /etc/modprobe.d/iwlwifi.conf：。
options iwlwifi 11n_disable=1 swcrypto=1这也不起作用所以我撤消了我所做的操作。
从附加驱动程序下更改选定的驱动程序。但我的驱动程序下没有 wifi 驱动程序。我只有 nvidia 显卡。所以我猜它没有使用我的网卡的附加驱动程序。
尝试了可启动 USB 并启动到 manjaro、ubuntu 20.10、elementary 5.1，但都面临同样的问题。wifi 速度太差，而且经常断开连接。
我在 ubuntu 上勉强能达到 30Mbps，但如果启动到 Windows，我就能达到 300Mbps。有时我能达到 80-90Mbps，但从来都不是全速的。启动时没有互联网，我必须等待几分钟才能上网。我在 LAN 上能达到 300Mbps。我连接的所有其他设备也能达到全速。只有当我使用 ubuntu 和 wifi 5ghz 网络时，我的笔记本电脑才会出现问题。
我的笔记本电脑型号 gf63 薄型 9SC 酷睿 i5 第 9 代 nvidia 1650
我今天花了一整天时间解决这个问题。可能不得不切换回仅 LAN。当我在家时这没问题，但当我在旅途中时就不太好。

答案1
这就是我解决问题的方法。我找不到更好的方法来解决这个问题。我希望这不会影响我的工作。
搜索了两天之后，我还是没能找到任何解决方案。因此，我最终决定尝试更改一些设置。我看到状态栏中出现了 nvidia 图标，这是我以前从未见过的。一年多之后，我又回到了 Ubuntu。这个图标对我来说是新的。因此，我点击了它，选择了性能模式，它让我可以选择英特尔省电模式。我选择了它，我的 Wi-Fi 问题就解决了。我尝试从附加驱动程序选项卡更改 Nvidia 驱动程序，但它们都存在同样的问题。最后，我选择了 Nvidia 开源驱动程序，没有专有驱动程序。这也解决了我的问题。但是 Nvidia 图标不再显示在状态栏中。因此，我不确定 Nvidia 卡是否工作正常。 选择了 Nvidia 开源驱动程序
