恢复后 Wifi 无法使用

我遇到了一个问题，我的 wifi 恢复后无法工作。

我已经在谷歌上尝试了很多解决方案。

我目前拥有的：

猫/etc/pm/sleep.d/wakenet.sh

#!/bin/bash
case "$1" in
thaw|resume)
nmcli nm sleep false
pkill -f wpa_supplicant
;;
*)
;;
esac
exit $?

猫/etc/pm/config.d/config

SUSPEND_MODULES="ath10k_pci"

恢复后的错误日志：

我现在真的需要帮助。谢谢！

我用了奥维斯·隆的回答类似问题启用我的笔记本电脑（Dell Precision）16.04 LTS 版本挂起后自动恢复 wifi 的功能。

像 Owais 一样，我创建了 /etc/pm/sleep.d/10_resume_wifi：

#!/bin/sh

case "${1}" in
    resume|thaw)
      nmcli radio wifi off && nmcli radio wifi on;;
esac

后面跟着一个sudo chmod +x /etc/pm/sleep.d/10_resume_wifi。

如果你像我一样对双分号或单括号感到疑惑，请参阅http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_03.html—— 这就是 case 语法的工作方式。

我终于找到了解决方案！只需编写此脚本即可在挂起之前删除模块，然后重新加载。
