我最近从 11.10 升级到了 ubuntu 12.04，从那时起我就无法连接到互联网，无论是使用 wifi 还是使用以太网。我读了很多帖子，但没有找到任何解决方案。我的笔记本电脑是 64 位 HP-G61，我的 wifi 卡是 Atheros AR9285，我的以太网卡是 Realtek RTL 8101E/RTL8102E。升级之前，一切都运行正常。我尝试使用终端执行手动网络配置，但没有成功。有人知道我该如何解决这个问题吗？是否可以切换回旧的 11.10？提前非常感谢，我附上了一些命令的输出

以下是相关主题及其解决方案Ubuntu 论坛。
简而言之：通过编辑将不兼容的模块列入黑名单
/etc/modprobe.d/blacklist-network
并添加以下行：
r8169.ko
然后r8101从 Realtek 网站或从这里
将新模块复制并安装至：
/lib/modules/3.2.0-23-generic-pae/kernel/drivers/net/ethernet/realtek/
然后输入：
sudo depmod -a
sudo modprobe r8101
您可能需要修复缺失的 MAC 地址并重新启动网络管理器。请使用唯一的（最好是原始的）MAC 地址，而不是< MYMAC >下面的地址。
sudo service network-manager stop
sudo ifconfig eth0 down
sudo ifconfig eth0 hw ether < MYMAC >
sudo ifconfig eth0 up
sudo service network-manager start
