我注意到，当我的电脑插入电源时，无线信号强度会增加。我猜想这与电源管理有关。
有没有办法禁用无线电源管理？
我发现了一些博客文章，其中展示了禁用此功能的技巧，但最佳做法是什么？电源菜单中是否应该有一个选项可以让你切换此功能？

答案1
输入以下内容编辑以下文件：
sudo gedit /etc/rc.local
添加以下几行以禁用 wlan0 无线：sleep 10（这为无线加密狗/卡提供了加载时间，然后再执行下面的命令）“iwconfig wlan0 power off”
重要！确保最后有一行内容：
“退出 0”
这将绕过任何错误并允许系统继续启动。
您也可以在这里添加其他启动命令 - 非常有用。
它应该看起来像这样：
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sleep 10
iwconfig wlan0 power off
exit 0

答案2
几年前我遇到过同样的问题，我认为这仍然有效：http://uselessuseofcat.com/?p=67
答案3
建议的做法是（以 root 身份）block-powermanagement在/etc/pm/config.d/目录中创建一个文件（例如），并添加以下行HOOK_BLACKLIST="$HOOK_BLACKLIST wireless"。
echo HOOK_BLACKLIST=\"\$HOOK_BLACKLIST wireless\" | sudo tee /etc/pm/config.d/block-powermanagement
应该这么做。
