我的系统已与 Windows 实现双启动。但只有在 Ubuntu 上，我才遇到 Wifi 不断断开的问题。我没有网线，所以我需要一个没有网线的解决方案。
我启动了 Ubuntu，一切正常，但当我开始启动应用程序等时，我总是断开连接。我不知道是不是我的某个程序干扰了我的 wifi。
我尝试了不同的方法来解决这个问题。这是我运行一段代码时得到的日志：

您的问题报告中的关键细节可能是您的网络设备是 RTL8111/8168/8411。
17.04 中似乎存在问题，因为发行版中没有包含正确的模块。
要检查您是否受到影响，请执行以下操作：
lshw -class network | grep RTL8111/8168/8411
product: RTL8111/8168/8411 (...) # (1)
lsmod |grep r8169
r8169 81920 0 # (2)
（1）表示你的硬件是RTL8168
（2）表示你的驱动程序是r8169
这不是一个兼容的组合，因为 8169 驱动程序无法与 8168 硬件正常工作
要解决此问题，您需要安装 dkms 和 r8168-dkms。
如果您很幸运并且可以暂时访问互联网，那么请执行以下操作：
sudo apt install r8168-dkms
否则，您必须检查 dkms 是否已安装 (3)，然后安装驱动程序 (4)，方法是将其安装到您的系统上并直接使用“dpkg -i”。如果 dkms 未安装，则可能需要安装一些东西。
dpkg -l | grep dkms # (3)
ii dkms 2.3-3ubuntu1 (...)
dpkg -i r8168-dkms_8.043.02-1_all.deb # (4)
我希望这能解决你的问题。
