Hi Backflip and welcome to the forum!
Checked out your Wireless card and it seems that Linksys didn't release a vista driver
for your specific version.
There are several posted solution and download location for alternative drivers
that would work with your card but could not post the links here as I could not verify their effectiveness or reliability.
If you'd want to pursue that way, please read the posting from TechNet, here.
If all else fail, you could try the Windows 7 Driver solution, here.
