When you uninstall the drivers, make sure you keep selecting "delete the driver software" checked until you get the unknown device (Network Adapter) shown in the device manager. Then update the drivers again. If this solution doesn't get rid of the "2" in the "WiFi 2," you have to do a registry delete the name "WiFi" and then renaming "WiFi 2" to "WiFi" in the network connections page. I honestly don't know if this method works for Windows 8.1 but this is how I solve the "wireless network connection" duplicates in Windows 7.
As for the "Hyrule 2," in Windows 7, there's the screenshot below where you can delete network locations aside from network profiles. You'll see your duplicates there. All you have to do is merge the duplicate network to the original network and that should fix it.
