我已经安装了 ubuntu 20.04LTS。我的笔记本电脑是 HP probook 645 g4,amd ryzen7。这台笔记本电脑使用英特尔无线 ac3168NGW 来使用 wifi。安装 Ubuntu 后,软件和更新中的“附加驱动程序”显示英特尔公司:双频无线-AC3168NGW [stone peak]-此设备不工作。并给我一个继续使用手动安装的驱动程序的选项。我尝试了 2 种常见的解决方案。wifi 连接后突然断开连接。断开连接后,在系统设置的 wifi 部分,显示未找到 wifi 适配器。并且 wifi 开关按钮消失了。这真的很痛苦。我给出了以下 2 个解决方案。这些都不能完美地工作。如果有人给我一个完美的解决方案,
我的尝试-1:
wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-3168-ucode-22.361476.0.tgz
tar xvf iwlwifi-3168-ucode-22.361476.0.tgz
cd iwlwifi-3168-ucode-22.361476.0
sudo cp iwlwifi* /lib/firmware
sudo modprobe -v iwlwifi
我的尝试-2:
sudo apt update
sudo apt install linux-generic-hwe-20.04
并且..我没有使用任何双启动。我已经在整个硬盘上安装了 ubuntu。“dmesg | grep iwl”结果如下。

在您的编辑中,我们看到许多重复的内容:
iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x2000000.
iwlwifi 0000:02:00.0: Start IWL Error Log Dump:
这里有一个关于固件崩溃和英特尔 3168 的很长的错误报告:https://bugzilla.kernel.org/show_bug.cgi?id=204151这表明该问题已在内核版本 5.5 及更高版本中得到修复。我相信 Ubuntu 20.04 LTS 使用的是内核版本 5.4。
我建议您下载 Ubuntu 20.10 的 iso,它目前使用内核版本 5.8。接下来,尝试实时会话,也称为“尝试 Ubuntu”。
你的无线网络工作正常吗?消息日志中有什么线索吗?
dmesg | grep iwl
所有其他功能(例如电子邮件、网页浏览器等)是否按预期工作?如果是,我建议您安装它。
编辑:请检查固件文件的完整性:
md5sum /usr/lib/firmware/iwlwifi-3168-29.ucode
我们希望你看到:35ba5d5a8bdd6ff453106d268eda957e
如果没有,请执行以下操作:
sudo apt install –reinstall linux-firmware
重启并检查:
dmesg | grep iwl
有改善吗?
如果不是,请重命名 -29 版本,以便系统加载 -27:
cd /usr/lib/firmware/
sudo mv iwlwifi-3168-29.ucode iwlwifi-3168-29.bak
重启。有什么改善吗?如果没有,请恢复更改并重启:
cd /usr/lib/firmware/
sudo mv iwlwifi-3168-29.bak iwlwifi-3168-29.ucode
