我刚刚在 UX31A Notebook Asus 笔记本电脑上安装了 Ubuntu 20.04。
Wi-fi 前 2 分钟可以正常工作，然后就关闭了。我无法重新启动它并收到错误消息：“未找到 Wi-Fi 适配器”
我试过：
- 通过 ubuntu iso 重新安装 Wi-Fi 驱动程序。但没有其他驱动程序需要安装
- 禁用安全启动模式
- 在各种帖子中发现了很多随机的东西
- fn+F2 仅启用/禁用飞行模式，对 Wi-Fi 没有影响
- 检查BIOS中的参数，Wi-Fi未被阻止
这是一些诊断命令的输出

有人知道如何启用网络吗？
感谢您的帮助 ！

诊断
请发布输出
$ lspci -nnk | grep -i -A2 net
$ ip a
$ sudo ip link set wlp2s0 up
$ ethtool -i wlp2s0
$ service network-manager status
$ uname -a
$ ls -al /etc/modprobe.d
$ cat /etc/modprobe.d/modprobe.conf
$ cat /etc/modprobe.d/iwlwifi.conf
$ cat /proc/cmdline
$ modinfo iwlwifi
$ ls -al $(locate rfkill | grep service)
编辑
$ dmesg | grep phy0
另外，您可以安装hardinfo和检查电脑->内核模块，设备->PCI 设备，网络->接口->wlp2s0。
我认为这与内核版本无关，正如一些人在旧帖子中所报告的那样。
可能的解决方案
尝试：
编辑
这和这显示选项可能被放置在合适的
/etc/modprobe.d/文件中rfkill.conf。我不确定哪些适用于iwlwifi。我会尝试添加options rfkill master_switch_mode=1 options rfkill default_state=0归档
/etc/modprobe.d/rfkill.conf并重新启动。这个帖子在 slackware 的一个旧线程中，显示了一个类似问题的解决方案。您可以尝试检查整个线程并找到与您当前的 Ubuntu 可能的相似之处。发布任何部分结论也会有所帮助。
这个帖子和这在 archlinux 的旧线程中展示了另一个类似问题的解决方案，将某些驱动程序列入黑名单。显示了 archlinux 的类似解决方案这里进行软阻塞。因此您可以尝试
echo "blacklist asus_wmi" | sudo tee /etc/modprobe.d/asus_wmi.conf（例如使用这里（其中的一个帖子 chilli555 参与）并进一步喜欢这里完全列入黑名单依赖项。我不确定
asus_wmi要列入黑名单的模块是否正确。重新启动并运行sudo rfkill unblock all
我想您可能会尝试找到正确的配置文件，在其中删除驱动程序、解除阻止，然后重新加载驱动程序。 这似乎可以做到这一点，但是在命令行和软阻止方面，与您的情况不同。
我将等到您发表反馈。
