Hi I narrowed it down to 2 Drivers. An Intel wireless and a Broadcom Wireless. Here is a link:

Download the intel mobile chipset driver first.
These Drivers are for XP. I am unsure what OS you are using. If you have a different OS please post. I would try the Broadcom driver first. If it does not work then uninstall it and use the Intel Driver. Also Post what other drivers you may be missing. They would be in the Device Manager highlited with a yellow or red exclamation point.
Thanks,
Bill
