1.sudo service network-manager stop;
2.sudo service network-manager start;

sudo systemctl restart NetworkManager

目前使用开源驱动 brcm80211。可尝试执行以下指令

代码： 全选

sudo apt install pm-utils
echo SUSPEND_MODULES="$SUSPEND_MODULES brcmfmac" | sudo tee -a /etc/pm/config.d/unload_modules

然后执行 sudo pm-suspend 待机。观察唤醒后能否使用无线网。
若无效，再尝试通过“附加驱动”安装无线网卡的私有驱动。
