Ubuntu 18.04-未找到无线适配器

今天早上我的 wifi 莫名其妙地无法连接。昨晚我让它处于休眠状态,工作正常,今天早上它无法连接到互联网,并出现 No-Wifi-Adapter-Found 错误。
输出:

我有

  • 重启多次
  • 已禁用安全启动
  • 跑了sudo rfkill unblock all
  • 跑了sudo rmmod iwlmvm && sudo modprobe iwlmvm
  • 跑了sudo service network-manager restart
  • 将 iwlwifi 5.2+ 固件解压到 lib/firmware 中
  • 在 /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf 中将 wifi.powersave 更改为 2
  • 跑了modprobe iwlwifi 11n_disable=1 bt_coex_active=0
  • 跑了 sudo apt update sudo apt install git build-essential git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git cd backport-iwlwifi/ make defconfig-iwlwifi-public sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config make -j4 sudo make install sudo modprobe iwlwifi

我已经束手无策了,如果能提供任何修复建议我将不胜感激。非常感谢!!
