Ubuntu 20.04-未找到 WiFi 适配器

Ubuntu 20.04-未找到 WiFi 适配器

今天我组装了第一台电脑,并在上面安装了 Ubuntu 20.04.03 LTS。Ubuntu 是这台机器上唯一的操作系统。构建如下

MSI Z590 Pro Wifi Motherboard
Intel i7-11700K CPU
G.SKILL Ripjaws V Series 32GB (2x16GB) DDR4 3200 RAM
Corsair CX-F CX550F 550W PSU
Samsung 970 EVO PLUS M.2 2280 1TB PCIE 3.0 x4 NVMe SSD
be Quiet dark rock slim CPU Cooler

主板内置有 wifi 和蓝牙。(WiFi 卡是 Intel AX210 160MHz)蓝牙工作正常,但 WiFi 不工作:我收到错误“未找到 WiFi 适配器”。

内核版本是: 5.11.0-37-generic

输出来自lspci -knn | grep Net -A3; rfkill list

弹出了错误Failed to run INIT ucode: -110,但是当我查看该错误时,所有修复方法都不起作用。我目前通过 USB Tether 连接到我的 iPhone,并尝试运行它,sudo apt-get update && sudo apt-get upgrade但它没有修复它。我也尝试重新安装 Ubuntu,但无济于事。

我不知道还能尝试什么。有什么想法吗?

看起来解决方案是删除/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm文件。

来源https://bugzilla.kernel.org/show_bug.cgi?id=212371

请注意,如果linux-firmware软件包更新,则该文件会出现。如果问题无法及时解决,Wi-Fi 将再次停止工作。
