由于网络管理器和英特尔无线 7260ac 卡存在错误，我已切换到 Wicd，但 wicd 仅显示 abgn 速度，我该如何恢复 AC 速度？
https://help.ubuntu.com/community/WICD
我也知道我可以通过输入关闭 wifi 电源管理sudo iwconfig wlp3s0 关闭电源如何在重启后关闭 wifi 电源管理？
我知道如果我使用网络管理器，我可以按照以下步骤将其关闭，但是我正在使用 Wicd，在 Wicd 中关闭 wifi 电源管理的步骤是什么？
Go to directory
/etc/NetworkManager/conf.d/
and open the file
default-wifi-powersave-on.conf
By default it is wifi.powersave = 3 so just change it to wifi.powersave = 2.
我也做了uname -a

我也做了lsb_release -a
