WMP54G on vista help

I was wondering if anyone can help me with getting the interned working.
I recently updated from XP to Vista Business (64-bit) and i am having a problem with my Wireless adapter. I have WMP54G v4.1 and i can't get my PC to read my adapter. Please help me.

 

Are the drivers installed for your Wireless adapter. Vista 64 bit has different driver requirements. Do you know how to get into Device Manager?

 

no i don't really know anything about Network. I went to the computer store today and they told me that this Wireless card should work.

 

I doubt the average "computer store" employee understand that a 64-bit operating system requires specific drivers. I don't see any such drivers for this adapter on LInksys's website.

 

I can't find one either. Who recommended that you upgrade that machine to Vista?

What is the make/model of the machine in question??
