Ubuntu 22.04 上的 Wifi 速度明显比 Windows 上慢

我的 Ubuntu 22.04 上的 Wifi 速度明显低于 Windows 上的。我尝试了以下所有以前的解决方案：Ubuntu 20.04 双启动 (DELL XPS-L502X) 上的 Wifi 速度很慢且不稳定
在我的笔记本电脑上，ubuntu 上的 wifi 比 windows 上的 wifi 慢

将 改为wifi.powersave2 也无济于事。 也没有用rfkill unblock all。

有人可以帮忙调试并修复该问题吗？

答案1

找到11n_disable=1设置的位置并将其更改为11n_disable=8。就我而言，我这样做了：
sudo nano /etc/modprobe.d/iwlwifi.conf并进行了编辑。
