NIC Drivers / Obtaining them from Microsoft Update w/o having a nw

I have three NICs and, unfortunately, all three are non-functional with Vista
B2. The update advisor suggests that my USR 802.11g turbo PCI adapter has a
driver - available through Microsoft Update. Convenient, if it weren't the
-network- card that needs the driver. =) There is no support from the vendor
for any of my cards, so is there any way to d/l this driver from MU on a
separate computer? They used to have a section for IT admins to d/l
individual packages/updates, but I don't see anything like this that contains
3rd party drivers...

My other main NIC is a Netgear WG121.

Thanks!
