这个问题已经持续了几个月了。经过一次又一次的故障排除失败后，我终于屈服了，并向您寻求帮助。我想先说一句，Ubuntu 现在是我喜欢并经常使用的操作系统。
我搜索了 askubuntu 论坛并尝试了许多提供的解决方案，但没有一个能够解决这些问题。ndiswrapper 也不起作用。
任何关于此问题的帮助都将不胜感激:)
编辑1：更详细地说，我的无线网络只能连接到 1 个路由器（ssid：NETGEAR-2.4G）。我无法连接到我们家里的第二个路由器（ssid：4NXG）。我正在使用无线连接访问这些论坛，但以太网仍然无法工作。如果可能的话，我想解决以太网和无线问题。
编辑2：根据 Elder Geek 的建议，我正在编辑这个问题以仅处理以太网问题。
编辑3：根据要求添加了额外的 lspci 信息。
编辑5：添加了更多信息，太多信息了
当前的问题
- 以太网显示“已连接”，但实际上没有连接。以太网很少会突然开始工作。然后立即再次停止工作。
- 路由器看到我的电脑（通过 192.168.1.1 远程访问时）
- Ping google.com 或任何 ipaddress 都会导致数据包丢失。
- 端口转发不起作用
症状（时间线）
2015 年 1 月 - Linux Mint Rebecca 安装。无线运行良好，以太网运行良好。
2015 年 2 月初-端口转发突然失败。
2015 年 2 月中旬 - 有线连接失败。只有无线可用。
我已安装 Ubuntu 14.04.02（当前操作系统）、Debian 7.8.0 和 Linux Mint Rebecca。所有全新安装均无法实现以太网连接。
连接到以太网后，无线路由器可以看到我的电脑，我的电脑显示“已连接”。但是，所有网页查询都超时。ping google.com 导致 100% 数据包丢失。

下载并安装适用于内核 3.x、2.6.x 和 2.4.x 的 LINUX 驱动程序这里
在桌面上创建一个临时文件夹并将内容提取到其中。您将看到以下内容：
使用以下命令打开终端CtrlAltT
切换到内容的目录。就我而言。
cd ~/Desktop/temp/r8101-1.026.00/
然后发出命令sudo ./autorun.sh这将安装支持您的以太网芯片组的驱动程序。
打开网络连接，选择有线连接，选择
