![笔记本电脑无法初始化 iwlwifi](https://linux22.com/image/1067625/%E7%AC%94%E8%AE%B0%E6%9C%AC%E7%94%B5%E8%84%91%E6%97%A0%E6%B3%95%E5%88%9D%E5%A7%8B%E5%8C%96%20iwlwifi.png)
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。
