I am having a problem using wired connection for Ubuntu 13.10. The problem started suddenly. However I was able to solve it using the answer given in the following post:
Ubuntu 12.04 Dell 6400 no network
It worked perfectly. But now again I am unable to connect to the internet. I tried using the same solution but it was of no use. I have reinstalled the driver for Realtek Ethernet Controller (r8168 ==the latest version) using the answer given in this post:
Wifi and Ethernet connectivity problems after upgrading to 12.04
But these solutions are not solving my problem.
