我重启了我的 PC，一台装有 Ubuntu 18.04 的 ASUS X555L。没有出现 wifi 网络，并且激活了飞行模式。
结果：
iwconfig
enp5s0 no wireless extensions.
lo no wireless extensions.
wlp4s0f0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=off
Retry short long limit:2 RTS thr:off Fragment thr:off
Power Management:off
然后尝试
ifconfig

您尝试的第一个命令是sudo ifconfig wlp4s0f0 up
因此
sudo ifconfig wlp4s0f0 up
SIOCSIFFLAGS: Operation impossible because radio frequency is off
我发现无线电频率存在问题，并进行了测试rfkill
rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
我可以解锁射频，但它不工作sudo rfkill unblock all，它仍然出现Hard blocked: yes
我想看看我的网卡是什么，所以运行

我不知道如何操作 Wi-Fi 以及如何禁用飞行模式。
我已经使用 Ubuntu 很长时间了，从来没有遇到过这样的问题。我搜索了很多论坛，但还是找不到解决方案。我试过了所有方法。
答案1
尝试按Fn+F2关闭飞行模式。
如果没有帮助，请在终端中运行：
sudo modprobe -r asus_wireless
