Ok, I've tried to follow every example I could find but nothing is working. I need your help. One day an update came along and I lost my ethernet. A failed version upgrade eventually resulted in a reinstall of 15.04, then I upgraded to 15.10. In each version I have tried to download the current Realtek RTL8101E driver (I've also tried r8169 from the realtek site). I can get the r8101 module loaded but I can't even ping my router with the wired connection. Wireless IS running on the ath9k driver. Here is some detailed info:
