Windows 7 Networking Problems

Note: This article is a work in progress.

Things to Check when you're having problems with networking in Windows 7:

Task Offloading

The next thing to try, if that doesn't fix it, is to disable Task Offloading on your NIC. Go to the Advanced tab of the NIC's properties and disable everything related to "offload". Make a note of what you did and what the default settings were before you start, so that you can revert the changes if they do not help.
