Hello, I have Ubuntu 11.04 and Windows 7 Professional dual-booted on my system (I'm currently posting from Windows). The problem I am having is that neither of my LAN/Ethernet ports are communicating while in Ubuntu, however the connections manager recognizes eth0 and/or eth1 as viable connections options (though it claims an Ethernet cable is not connected...) I assumed the issues were related to a lack of drivers/modules to make the ports work as intended, but after installing the modules in Realtek's repository the ports still do not communicate.

I have dabbled with the terminal, and I understand basic commands and how to execute them.

My system has a Gigabyte Technologies motherboard, model number EP45T-UD3R revision 1.0. The LAN/Ethernet ports are listed in Windows Device Manager as "Realtek RTL8168C(P)/8111C(P) PCI-E Gigabit Ethernet NIC" and this board has two (identical) LAN ports. I'm not sure if you need any more technical information about my hardware, but if you do I have all of the components in my system on Overclock.net here (the hardware list is near the bottom of the page).

I HAVE tried NDISwrapper, I extracted the proper INF and SYS files from the sfxexe that Gigabyte provided, installed NDISwrapper using Terminal from the Ubuntu install USB stick I made, and told NDISwrapper to install and load the INF, but that didn't seem to make a difference to the connection manager (maybe I'm missing something?) but the wrapper did not spit out any errors. However, I have a sinking feeling NDISwrapper might only look for wlan, which won't do me a damn bit of good since they're ethernet ports (correct me if I'm wrong).

If anyone can assist me in this endeavor I would greatly appreciate it. If we can't figure out how to get Ubuntu to use my Realtek Ethernet ports, I wouldn't mind someone suggesting a cheap PCI LAN/Ethernet card to stuff in my system (I would prefer PCI over PCI-e, but either way) that has FULL compatibility with both Windows and Ubuntu.
