Has anyone had any problems with this integrated NIC? I have it on my Gigabyte EP45-DS3L. The Stock Drivers on the Gigabyte CD work great for XP and Vista, and what came in on my Win 7 RTM work great. But if I update the drivers, either by using Windows Update in any of the OS's, or even going to RealTek's website, it effectively breaks the NIC. What happens is after the update, everything fine, but then it starts acting like a wireless card with iffy 3rd party software. I lose connection, regain it, lose it again, etc. Rebooting the computer, and the router don't fix this for very long. And its also WIRED. And I know the wires good, made it, and tested it before using it, I even retested it again when the updates broke the card. Now this does happen in all three OS's. Windows XP, Windows Vista, and with Windows 7. Rolling back always fixed the issue. Anyone had this issue? Any ideas of why this happens?
