Hi, Steve:
Please go to the device manager and click on the Network Controller device you see listed there and post the hardware ID for it.
Use this guide for how to find the hardware ID for a device.

Then I will post the link to the W7 64 bit driver you need.
If you are missing any other drivers you can post the hardware IDs for those too and I will post the links to the drivers you need.
