我最近在台式机上安装了 Intel AX200 无线 PCIe 卡。我无法让该卡工作。我读过很多其他有类似问题的问题，但无法修复它。
以下是一些信息：

错误代码 -110 似乎是问题所在，但我不知道它是什么意思，也不知道该如何修复。此卡还具有蓝牙功能，可以正常工作。
编辑：我已经升级到 5.10 内核，没有任何变化。
uname -r

答案1
对 AX200 的支持有时确实时好时坏。尽管如此，许多运行 5.10 内核的人报告说他们的英特尔无线网卡运行正常，并且数据传输率可观。
如果您想尝试将内核升级到 5.10，请继续阅读...
将内核升级到 5.10
笔记：以下所有命令均从终端运行。
首先，让我们确保您的系统是最新的：
sudo apt update
sudo apt dist-upgrade
清理已安装的软件包并稍微 apt 一下：
sudo apt autoremove
sudo apt clean
现在让我们获取 5.10 内核。我们将把源文件放入其中，/tmp因为安装后没有必要保留它们。因此：
cd /tmp
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.17/amd64/linux-headers-5.10.17-051017_5.10.17-051017.202102170631_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.17/amd64/linux-headers-5.10.17-051017-generic_5.10.17-051017.202102170631_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.17/amd64/linux-image-unsigned-5.10.17-051017-generic_5.10.17-051017.202102170631_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.17/amd64/linux-modules-5.10.17-051017-generic_5.10.17-051017.202102170631_amd64.deb
接下来我们进行安装：
sudo dpkg -i *.deb
最后，重启系统：
sudo shutdown -r now
系统重新启动后，使用 在终端中检查内核版本uname -r。
如果你读到这里，我希望这能给你一个可用的网络设备
