升级到12.04后出现Wifi和以太网连接问题

我最近从11.10升级到ubuntu 12.04,从那以后我无法连接到互联网,也没有使用wifi,也没有使用以太网。 我一直在阅读很多post,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。 在我升级之前一切正常。 我试图使用终端执行手动网络配置,但它不起作用。 有谁知道我该如何解决这个问题? 是否可以切换回旧的11.10工作? 非常感谢你提前,我附上了一些命令的输出

这是Ubuntu论坛上解决方案的相关主题。

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 

然后从Realtek网站或此处查找或构建有效的r8101驱动程序/模块

将新模块复制并安装到:

 /lib/modules/3.2.0-23-generic-pae/kernel/drivers/net/ethernet/realtek/ 

然后输入:

 sudo depmod -a sudo modprobe r8101 

您可能需要修复丢失的MAC地址并重新启动网络管理器。 使用唯一的(最好是原始的)MAC地址而不是下面的< MYMAC >

 sudo service network-manager stop sudo ifconfig eth0 down sudo ifconfig eth0 hw ether < MYMAC > sudo ifconfig eth0 up sudo service network-manager start
