![AX211 wifi 在 ubuntu 20.04 上运行没有希望吗?](https://linux22.com/image/1207653/AX211%20wifi%20%E5%9C%A8%20ubuntu%2020.04%20%E4%B8%8A%E8%BF%90%E8%A1%8C%E6%B2%A1%E6%9C%89%E5%B8%8C%E6%9C%9B%E5%90%97%EF%BC%9F.png)
我在笔记本电脑上全新安装了 ubuntu 20.04,然后 apt 更新并升级到最新版本。
$ uname -r
5.13.0-39-generic
到目前为止,BT 运行良好,但现在只有 wifi 无法使用。
我检查了以下内容
$ lspci -nnk | grep 0280 -A3

根据这个答案ubuntu 20.04 LTS 驱动程序英特尔 WI-FI 6E AX211 160MHZ
AX211 在内核 5.14 中受支持,因此遗憾的是,即使是 20.04 LTS 的 HWE 内核也不支持
那么 ubuntu 20.04 运行 AX211 wifi 模块就没希望了?还是只能等待更新?
答案1
我通过安装从以下位置下载的最新 dkms backport-iwlwifi-dkms_9858-0ubuntu2_all.deb 解决了此问题https://launchpad.net/ubuntu/+source/backport-iwlwifi-dkms
简单地
$ sudo dpkg -i backport-iwlwifi-dkms_9858-0ubuntu2_all.deb
然后重启。现在 wifi 运行正常!
