r8168 Realtek works on 14.04 -- then when run updates - I loose networking

[xigen]

I have been having issues with 14.04 64 bit ubuntu and r8169.

I replaced realtek r8169 with r8168
http://ubuntuforums.org/showthread.php?t=2240533&page=3&p=13106182#post13106182

Networking worked. All was good.

Then I installed updates - and my network did not connect

Then I tried to do exactly what I did on a fresh install of ubuntu 14.04

I went to Downloads - unpacked the file - and as instructed: sudo ./autorun.sh

unfortunately - my networking did not work.

How do I see what is going wrong and fix it?
