Network Adapter Problems Again?

Hello so the title sums it up that i'm having network adapter problems. I'm gonna break it down
Motherboard: Gigabyte 970A-D3
Network Card/Adapter (According to disc) Rtl8111
OS: Windows 7 64
How this happened: I restarted my computer a few days back and I turned it back on with no internet and I troubleshooted the problem and windows said no network adapter detected.
Additional Details: Sometimes the problem will be fixed by restarting the computer a couple times etc. Going to Bios and disabling and enabling Lan Card stuff. But now doing so did not fix it.(This has been going on several days.) I checked the back of my computer an no green light was on my network adapter but on my netgear router/modem the green light that detects internet or shows internet connectivity from my router/modem to my pc is still on. I have no internet (doing this on an iphone/Laptop) and no network adapter is on my device manager and it will only show if i go to device manager show hidden devices and boom network adapter shows but no realtek one i see Microsoft ISATAP Adapter, RAS Async Adapter, the norm would be realtek Pci Adapter something like that.
I really don't know what's going on with the thing. Any ideas?
P.S if you put buy a new one can you please leave a good suggestion of one price is fine don't really care
Again if you do my Motherboard is: Gigabyte 970A-D3

You say restarted your Computer I assume you ran the recovery software to re-install your operating system.
This if you Network card was part of your build should have installed the drivers.
So perhaps your P. C was a built one and not a manufactured one from one of the comp companies.

So basing on the latter have you run the disc you are talking about to install the drivers?
The latest drivers can be found at

If yes to all above and nothing has been changed then you could have a hardware problem
