I found a newer wifi driver that works with the Broadcom BCM4330 in the W510.
The driver is for a Lenovo, but installs fine on the W510.
I found the driver here, but it is probably available directly from Lenovo
http://www.notebook-driver.com/detail/thinkpad-driver-id-11129/
The driver that was on my W510 before this update was .68
Afterwards, it is .83
