Can't get network to connect after reinstall (Missing protocols)
I've been having some weird issues with my computer lately, so this weekend I decided to just do a full wipe and clean reinstall. So I got a fresh Win10 image from Microsoft, and installed that. However, after I was done I couldn't connect to the internet, and the diagnostics app said that one or more network protocols were missing. So I googled that error and started trying solutions I found, however none of them worked for me.
In the end I decided that since this seems to be a common issue for Windows 10, even though it worked perfectly fine before, I'll just try downgrading to Windows 8.1. So I did that, however it still doesn't work. Now it's telling me that my Ethernet adapter doesn't have a valid IP configuration. Once again, I googled for at least an hour and tried several solutions, none of which fixed it.
I was about to downgrade once more to Win7, but before that I decided to boot a Linux Live CD I had lying around, and I don't have any connectivity with that either, yet I know this CD worked perfectly fine before.
So now it kinda looks like my ethernet controller just decided to kill itself in the time I first reinstalled Windows 10. Which seems like a really weird coincidence, but I guess stranger things have happened. So today I went out and bought a PCI Ethernet card (edimax EN-9235TX-32), plugged it into my box, and it's showing me the same exact problem I also tried manually installing drivers from the CD, although it says on their website that Windows 10 already ships with the correct drivers included, so as you might guess that didn't help either.
I'm starting to get really frustrated by this, especially since I feel like I've probably tried every fix for this problem that's out there and nothing has helped me. Please if you have any ideas what might help, throw them at me, I don't mind retrying things I already did either. Feel free to include steps to check whether there might be a hardware problem, although I hope there isn't as I can't afford rebuilding the core system right now.
