如我所说这里我的无线连接无法正常工作。根据一些社区成员的支持对固件进行了一些更改后,我得到了以下输出:

sudo dmesg | grep iwlwifi输出:

[    3.373741] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)
[    3.381121] iwlwifi: No config found for PCI dev 02f0/0000, rev=0x354, rfid=0x0
[    3.381223] iwlwifi: probe of 0000:00:14.3 failed with error -22

我注意到子系统根据我上次运行的时间更改了条目 lspci -kvnn | sed -n '/Network/,/^$/ p'。它现在返回

00:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9462 [8086:02f0]
    DeviceName: Onboard - Ethernet
    Subsystem: Intel Corporation Wireless-AC 9462 [8086:0000]
    Flags: bus master, fast devsel, latency 0, IRQ 16
    Memory at c431c000 (64-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel modules: iwlwifi

有人知道我该如何继续重新获得无线连接吗?如果有必要,我也愿意格式化我的整个系统。然而,当我尝试在 20.04 版本旁边安装 18.04 Ubuntu 版本时,没有任何改进,我不确定这是否有帮助...

这是不是双启动。仅安装 Ubuntu 系统。

您正确假设了内核版本。 uname -r输出5.14.14-051414-generic

dmesg | grep iwl输出:

[    2.794034] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)
[    2.797944] iwlwifi: No config found for PCI dev 02f0/0000, rev=0x354, rfid=0x0
[    2.798042] iwlwifi: probe of 0000:00:14.3 failed with error -22

我使用以下方法从 dkms 树中删除了反向移植 sudo dkms remove backport-iwlwifi/8324 --all

dkms status现在返回

使用内核版本进行测试5.4.0-89-generic

dmesg | grep iwl没有返回任何东西...

dkms status返回
