Windows 10: Ethernet adapter Alternative Configuration TCP/IP v4 ignored

IP configuration not valid - interference from ethernet adapter?

I tried both of these solutions (have same problem, but to expand, my wireless doesn't connect to the internet either), and neither worked. Have intel AC 7260 wireless, and Atheros AR81g1 Ethernet (NDIS 6.30). Hope someone comes up with a solution soon. Windows 10 has been working....well, OK, for about a year on my personal laptop. My system bricked when I installed the Windows 10 Anniversary edition. Had backup on 2TB external drive. I installed clean windows 10, and all worked fine, including internet access on both wireless and ethernet, but needed to reinstall from my backup because of a lot of programs, and data there. Backup was about a month old (yeah, I know, backup more frequently). After a successful backup, I again attempted to install anniversary update. This time it installed successfully, and all appeared good until I tried to access the internet. Now my case is per above. Can't access from either Ethernet or wireless. It connects fine to my router (which I'm connected to on my company laptop right now), but it will NOT connect to the internet. HELP!!
