just updated using software manager and my network connection no longer works

view story

http://askubuntu.com – Earlier (last week or so) I installed r8168 drivers for network and they stopped the problem I had with occasional drop of internet. Tonight, I installed latest updates thru update mgr, which I noticed was a kernel update. I believe. Anyway after a restart, I no longer have internet access. I restarted my system and reverted to my previous kernel and internet connection was restored. Since I did a "custom" driver install with those r8168 drivers I am assuming that these things are somehow related. Please tell me how to use the new kernel with the R8168 drivers as they work bet (HowTos)
