I believe I am having the same problems. I updated, left everything running for over a week, no issues. Rebooted and the networking hasn't worked since. I tried several fixes mentioned, turning off and on bridging, bonding, cpu virtualization in the bios, different cables, its plugged directly into the modem and back into the router, got nada. I only have the onboard networking, it's a Realtek brand, I don't have a network card to test with, but I did boot windows and tried it, the ethernet is working just fine. Unfortunately I deleted my backup of the previous version, after running this one for a few days, so I cannot revert either. Any ideas?
