我使用 Fedora 39 KDE spin 作为我的日常驱动程序。自从安装以来一直困扰我的是无线网络的网速很差。 Windows 和我的其他智能手机上接收到的 Wifi 速度还不错。然而，尽管信号很强，但 Fedora 上的速度还是相当慢。
这是命令的输出inxi -Fzxx。

对于可能的解决方案，我尝试了以下两种。
sudo modprobe -r iwlwifi && sleep 5 && sudo modprobe iwlwifi 11n_disable=8
和
echo "options iwlwifi 11n_disable=8"| sudo tee /etc/modprobe.d/iwlopts.conf
应用此方法，我发现速度暂时提高了。然而，今天下午又下跌了。
可以采取什么措施来解决这个问题？
答案1
如果您的 SSID 在 2.4GHz 和 5GHz 范围内广播，当您遇到速度缓慢时，请检查 的输出$ iw dev wlo1 link。检查它是否freq在 5GHz 频谱内，并确保您有一个合适的rx bitrate和tx bitrate.
如果一切正常，请尝试关闭英特尔 WiFi 芯片组上默认启用的省电功能。检查当前状态
$ iw dev wlo1 get power_save
Power save: on
并将其关闭
$ sudo iw dev wlo1 set power_save off
$ iw dev wlo1 get power_save
Power save: off
