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. 18.104.22.168.40 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 better than the old ones. (Must add, according to directions I followed while installing r8168, I had to 'blacklist' the old drivers) Of course, I can't remember those procedures, being somewhat of a noobie.
