System: Lenovo X240 Thinkpad
OS: Ubuntu 14.04.1 64 bit LTS
Kernel: 3.13.0-37-generic #64-Ubuntu SMP (after update)

When I installed Ubuntu 14.04.1, the network was not configured. So I was left with a system without wifi and ethernet. I downloaded the rtlwifi_new driver from the git repository posted in comment #184. 

This compiles properly without any error.  I install it by running "sudo make install" inside the driver folder. 

$ sudo modprobe rtl8192ee
$ iwconfig
$ lshw -C "Network"

 sudo lshw -C "Network"

My wireless works properly without any problem. However, "ethernet controller" or Network LAN port does not work for me.  Is there any help for this. 

Also note that I did not install Kernel 3.16-rc7 as suggested many others here.  Let me know if there is a way to get the eth0 to work properly.
