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...
