[ubuntu] 12.04 network net doesn't work

view story

http://ubuntuforums.org – I've been trying to figure this out for a few days now. I've been running my machine no problems, right out of the box for years now. Then, one day, no internet. There's been a lot of posts all over that have been very helpful, but I've hit a wall. Below are some interesting reports from my machine: It appears that it's recognizing the hardware, but for some reason not loading the driver, or.. something else. Any help on this would be greatly appreciated. Code: $ lspci -nn | grep -e 0200 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express G (Hardware)
