Ubuntu 21.10上没有检测到Wi模块

Question

我的Ubuntu21.10的新安装在ASUS ROG STRIX X570-E游戏WIFI II似乎没有检测到wifi模块。蓝牙工作很好，我也禁用了快速启动。我认为这可能是一个内核问题，因为在旧版本中不支持WiFi 6E，但是在我的机器上它是5.15。

$ cat /proc/version
Linux version 5.15.0-051500rc6-generic (kernel@sita) (gcc (Ubuntu 11.2.0-7ubuntu2) 11.2.0, GNU ld (GNU Binutils for Ubuntu) 2.37) #202110180730 SMP Mon Oct 18 07:33:22 UTC 2021

任何帮助都是非常感谢的。

以下是基本设备清单的输出：

也是

sudo dmesg | grep iwl

什么都不回。

Answer 1

据我所见，它不在当前内核中。驱动程序可能能够操作芯片组，但是驱动程序中还没有硬件in。您将需要此修补程序：

https://patchwork.kernel.org/project/linux-wireless/patch/84ab45bf42f57fd0301c156ffc11d0fe330ff1f8.1636857817.git.deren.wu@mediatek.com/

不幸的是，这并不能直接应用于当前的原始代码。

   static const struct pci_device_id mt7921_pci_device_table[] = {
       { PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x7961) },
       { },
   };

(比照：https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/net/wireless/mediatek/mt76/mt7921/pci.c?h=v5.15.19 )

因此，您必须手动添加it并编译它。
