The UserManual.pdf of 2.1.4 states: Windows Vista no longer ships a driver for the AMD PCnet Ethernet card that provides to the guest by default [.]. As a convenience, ships with a 32-bit driver for the AMD PCnet card, which comes with the Windows Guest Additions. [.] Then, start the Windows Hardware Wizard and direct it to the Guest Additions CD where a driver for the PCnet card can be found in the directory 32bit Windows 3rdParty AMD_PCnet. But the directory 32bit Windows 3rdParty AMD_PCnet doesn't exist anymore in the iso image of the guest additions. I have quoted the relevant part of the UserManual.pdf in the ticket above. Which part of the manual did you mean?

Oct 15, 2001 - ODI 32-BIT LAN DRIVER. The AMD PCnet(TM)-PCI II Ethernet Adapter (AM79C970A) supports 10Base-T, 10Bese2, 10Base5, and 10Base-F.

If you follow these instructions, then you will not find the ethernet driver at the described location. I also showed that the driver is part of the 2.1.0 package but is missed in 2.1.2 and 2.1.4.
