I'm proud to say I was successful after weeks of troubleshooting.
Here is one solution that worked for me, and the files as promised if anyone else has the same issue.
Instructions are as follows:
Download
- Rollback the drivers on the Network Adapter in device manager
- Manually install the two .inf files after unzipping from the thumb drive.
- Then put in sleep, hibernate, restart, or reboot.
I also used
https://www.revouninstaller.com which is a totally free and awesome app to rid of bloat apps easily and all their nasty registry leftovers that slow your system down. (Not a sponsor)
This PC stick is snappy and happy to carry right along with most of the hardest of task outside of video editing, and obvious others.
If any one wants an unbloaded .iso or image just let me know.
I'll help where I can. Thanks for everyone's input and insight.
Here is handy info if any one so desires to dig deeper.
