我有一台新翻新的 HP 笔记本电脑:
HP HP ZBook 14u G5 英特尔® 酷睿™ i7-8650U CPU @ 1.90GHz × 8 AMD® Radeon pro wx 3100 / Mesa 英特尔® UHD 显卡 620 (KBL GT2)
我全新安装了 Ubuntu 22.04.2 LTS,内核版本为:5.19.0-42-generic
我发现计算机没有看到 wifi 适配器。以下是执行此操作的结果lshw – C network

我更新并升级了 Ubuntu,然后按照此页面上的说明安装英特尔驱动程序(iwlwifi-8265-22.ucode):
https://www.linuxfordevices.com/tutorials/ubuntu/no-wi-fi-adapter-found-error
仍然不起作用。
(对我的问题进行了新的编辑)。我在 Ask Ubuntu 上发现了一个与我的问题类似的问题,涉及相同的英特尔 wifi 固件:
对于此人而言,清除反向端口解决了问题。而对于我而言,反向端口不在计算机上:
sudo apt purge backport-iwlwifi-dkms
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package 'backport-iwlwifi-dkms' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded
这可能是问题所在吗?此外,反向移植又是什么?
当我做sudo dmesg | grep iwl
我收到以下消息:
[ 3.033851] iwlwifi 0000:02:00.0: enabling device (0000 -> 0002)
[ 3.754261] iwlwifi: probe of 0000:02:00.0 failed with error -110
最后,根据下面的评论,以下是rfkill list all

Hard blocked: no
输出lspci -vvnn | grep -A 9 Network

我现在已经浏览了多个不同的网站,发现 Ubuntu 22 显然存在很多网络连接问题。我不会把自己描述成超级用户,但我已经使用早期版本的 Ubuntu 多年了,从未遇到过这样的问题。另外,我知道 wifi 适配器可以正常工作,因为计算机最初配备的是 Windows 10,并且 wifi 工作正常(这就是我下载 Ubuntu ISO 的方式)。另外,从评论中的讨论中确认,飞行模式已关闭。
有人能提供一些帮助吗?
答案1
作为@Kuns 在最后一条评论中说道,在 BIOS 中关闭和打开 Wi-Fi 也对我的 DELL Latitude 5490 产生了效果 - 一台完全不同的设备。我认为这有点荒谬,但见鬼,我又有什么可失去的呢。
我先关闭了所有与 Wi-Fi 相关的设置,然后保存了设置。然后我重新打开了所有与 Wi-Fi 相关的设置,再次保存了设置,重启后,我的 Wi-Fi 也正常工作了。这真的有用,真是太让人困惑了,非常感谢!
