I am getting the same problem, any help isappreciated. Running an EVGA 680i Mobo, Windows 7 build 7600.

Edit:Never mind, I believe I just fixed it.Ganjamanyeah, try going to Control Panel -> Hardware and Sound -> Device Manager -> Click on Network Adapters dropdown -> Right-Click on the device(s), go to driver, and click 'Update Driver.' This worked for me, maybe it will for you too.

Yes, you need to update the network card driver for Windows 7 64-bit first. If Windows Update cannot find the driver update for your network card, you need to update the driver from the manufacturers website manually. In addition, you may also reset the router and update the firmware for your router to check the issue. Good luck!Arthur Li - MSFT
