我将 OpenWRT 安装到 TP-Link WR841ND 中。一切都按预期工作，但我无法让 wifi 开关工作。我按照上面描述的指南进行操作该路由器的 OpenWRT 页面。当我打开或关闭开关时，脚本/etc/hotplug.d/button/根本不会被执行。
可能是什么原因？是否缺少某些软件包或内核模块？

答案1
我升级到 OpenWRT 15.05.1，经过一番摆弄后，这似乎有效：我创建了一个脚本，其中/etc/hotplug.d/button/50-wifiswitch包含
#/bin/sh
if [ "$BUTTON" = "rfkill" ] ; then
if [ "$ACTION" = "released" ] ; then
logger "Disabling wifi"
uci set 'wireless.@wifi-device[0].disabled=1'
elif [ "$ACTION" = "pressed" ] ; then
logger "Enabling wifi"
uci set 'wireless.@wifi-device[0].disabled=0'
else
logger "Unknown action: $ACTION"
exit 1
fi
wifi
fi
注意事项：
- 按钮名称为
rfkill。 - 它实际上是一个开关，而不是切换按钮，因此 wifi 状态是由“按下”/“释放”决定的，而不是切换的。

您可能会遇到这个问题，因为 hotplug 正在被 procd 包取代，更多信息以及如何让按钮工作在这里： http://wiki.openwrt.org/doc/howto/hardware.button
当您的按钮正常工作时，请更新 wiki。
