笔记本电脑无法初始化 iwlwifi

Ubuntu 18.04 无法检测到我的笔记本电脑的 Wifi 适配器 Intel AC 9560。这似乎是在我笔记本电脑上安装 Ubuntu 的同一天随机发生的。这似乎是由于 iwlwifi 未正确初始化造成的。正如这里的其他一些帖子所建议的那样，我安装了反向移植的 iwlwifi 以将固件从版本 43 升级到 46。升级后，Iwlwifi 仍然无法初始化。我还能尝试什么？

请查看此错误报告：https://bugs.launchpad.net/ubuntu/+source/linux-oem-osp1/+bug/1835879这表明您的设备不受支持，但在软件包 linux-oem-osp1 中受支持。

您的设备还需要 18.04 版 linux-firmware 软件包中没有的固件。让我们来修复这两个问题。通过以太网、网络共享或任何可能的方式建立临时互联网连接，打开终端并执行以下操作：

wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.183.2_all.deb
sudo dpkg -i linux*.deb

接下来：

sudo apt update
sudo apt install linux-oem-osp1

还将安装几个依赖项。

重新启动并向我们显示新的：

dmesg | grep iwl

答案2

新固件导致我的音频输出出现错误

并且 iwlwifi 问题在几次启动和重启后再次出现

您可以再检查一下吗？

答案3

看来这招管用了！谢谢你的帮助。

正如该评论所述，https://askubuntu.com/a/1203223/1032323，使用此处描述的解决方案后音频仍失败，https://askubuntu.com/a/1201620/1032323。根据我的经验，我的笔记本电脑也无法关机或重启，而且会挂起。因此，我启动了原始内核并按照此处的说明进行操作装有 Ubuntu 18.04.3 LTS 的 Dell Vostro 15 5590 无线/音频无法正常工作。此解决方案解决了音频和关机问题，但iwlwifi驱动程序在挂起笔记本电脑后可能会失败。我可以重新加载驱动程序来解决这个问题，但我正在寻找更持久的解决方案。
