答案1

18.04 版更新答案

此处接受的解决方案对于 Ubuntu 18.04 来说已经过时了 -rtl8822be应该是开箱即用的。

  • 在安装过程中，Ubuntu 应该会检测你拥有的 Wifi 卡并为其安装正确的驱动程序，但要在 Ubuntu 18.04 上搜索任何其他可用的驱动程序，请转到软件与更新程序并点击附加驱动程序标签。

（点击“活动' 在桌面左上角。输入's' 在搜索框中输入应该足以显示可用的相关程序）

  • 另一个偶尔发生的“怪癖”是安全启动驱动程序签名存在问题并阻止其加载。

您可以通过检查机器的BIOS设置（通常通过按制造商选择的特定键来访问，例如f2或esc当您打开计算机时，但Grub 菜单还允许您选择“系统设置' 来查看您的选项）。

  • 在某些情况下，软件或硬件阻止可能会阻止 Wifi 连接。您可以通过rfkill list在终端中输入来检查这一点。

如果您仍然遇到问题，这里有一个很好的故障排除指南：https://help.ubuntu.com/stable/ubuntu-help/net-wireless-troubleshooting.html.en

答案2

我刚刚开始工作，一切都相当容易（经过谷歌搜索等）

  1. 安装最新的 4.14 内核和驱动程序代码（来自说明这里）

    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-headers-4.14.0-041400_4.14.0-041400.201711122031_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-headers-4.14.0-041400-generic_4.14.0-041400.201711122031_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-image-4.14.0-041400-generic_4.14.0-041400.201711122031_amd64.deb

sudo dpkg -i linux*.deb

  2. rtl8822befw.bin从以下位置下载固件文件这里。

  3. 将其保存在 中/lib/firmware/rtlwifi。请注意，较新的发行版可能已经有此文件。

  4. 重启。

享受

请注意，此驱动程序目前仍处于测试阶段，因此使用时请自行承担风险！

答案3

我可以确认@user776895 的答案修复了我的机器上的问题。非常感谢！！

不过，手动升级内核是否会导致 Ubuntu 启动菜单中出现新条目？根据这一页

wget linux-headers.deb ....
wget linxu-image.deb。

然后，可以通过在终端中执行以下操作来同时安装所有软件包：

sudo dpkg -i *.deb

此过程完成后，您的启动菜单上应该会出现一个代表上游内核的新条目（如果启动菜单未显示，请在启动时按 Shift）。这将显示为如下条目：

Ubuntu Trusty，内核 xxx.xxxx-generic

我使用过ukuu 并确认我的 grub2 菜单没有问题（没有看到新条目）

还值得一提的是，它
linux-firmware 1.161 不包含所需的固件，所以不要费心尝试

答案4

Chili555 的解决方案来自主题无线网络没有显示？对我来说很好用。运行以下命令：

sudo apt-get update
sudo apt-get install b43-fwcutter

然后重新启动笔记本电脑，wifi 网络就会显示出来。
