AX211 wifi 在 ubuntu 20.04 上运行没有希望吗？

2024-6-11 • tag-icon

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

根据这里的答案使用 iwlwifi 卡时无线网络不显示

我从以下网址下载了 backport-iwlwifi-dkms_9340-0ubuntu4_all.debhttps://packages.ubuntu.com/impish/backport-iwlwifi-dkms

并从以下位置下载 linux-firmware-20220310.tar.gz https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

dkms_9340 安装

安装 dkms_9340 如下

$ sudo dpkg -i backport-iwlwifi-dkms_9340-0ubuntu4_all.deb

复制 iwlwifi-so 文件

并从 linux-firmware-20220310 复制所有 iwlwifi-so-a0-* 文件

$ sudo cp iwlwifi-so-a0-* /lib/firmware

重启后

重启后，wifi 模块似乎已接通但无法正常工作

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！

dkms_9340 安装

复制 iwlwifi-so 文件

重启后
