Not to be mean: Please do not post unless contributing to the exact issue, thank you. It confuses the conversation.
The discussion is Windows 7 64 bit (Utlimate).
This is a real issue that can't be addressed via a basic troubleshooting script. It's not an driver issue unless MS updated them incorrectly. This worked for over a month flawlessly.
I am a senior software developer that also installs/works with Windows 2003/2008, etc (and contributed to Windows XP windows welcome coding).
After searching and find MANY users with the same experience I believe this issue needs attention by Microsoft.

6. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
7. In the Value data box, type 1, and then click OK.
8. Close Registry Editor.
