Vostro 2521: Wireless drivers installation fails

Hello,

Vostro 2521 (Service Tag:<ADMIN NOTE: Service tag removed per privacy policy>)

For various reasons we needed to reinstall the win7 os from scratch.

We used the following link to download and install the drivers. 

The wireless drivers' installations (there are 2) fail to install.

driver file names:

Network_Driver_9T8XY_WN32_10.0.0.309_A03.exe

Network_Driver_VHG5F_WN32_6.30.223.228_A05.EXE

Help would be much appreciated,

        Rami
