我想成为一名前端网页开发人员，有人建议我安装 ubuntu。我之前尝试过一些 ubuntu 版本（只尝试过 live cd），但我从来都不喜欢它。经过漫长的一天安装 ubuntu 后，我终于完成了。但我立即注意到没有互联网 --> 电缆被拔掉了。所以我回到 Windows 并尝试在线寻找解决方案。我设法安装了主板 utp 端口 RealTek PCIe GBE 系列控制器的最新驱动程序。当然，安装它们后我仍然无法上网。
我对 grub2 也非常恼火，我真的想删除 ubuntu 和 grub2。为此，我不得不再次启动 ubuntu（根据互联网）。但现在，奇迹般地，互联网正常工作了（我太高兴了）。我捣鼓了一下，安装了 sublime text、localhost、github 等。然后我启动回 Windows 玩游戏，之后当我返回完成我的 ubuntu 设置时，互联网再次失败。
我怎样才能解决这个问题？

编辑：尝试了很多解决方案，但都不起作用。Ubuntu 甚至无法执行“sudo ./autorun.sh”，它说没有这样的命令。当我在互联网上寻找解决方案时，我发现很多人都遇到了这个以太网芯片组 r8168 的问题。但还没有发布任何可行的解决方案。有人可以在 skype 上加我并帮助我吗？或者最好买一个 100% 有效的 pci 卡（当然不是 realtek 芯片组），有没有关于开箱即用的优质廉价卡的想法？它只工作了一次（我什么也没做）真是太奇怪了
