Thank you very much for your post
I understand that you have some questions in regards to the Silent installation of wireless drivers and PROSet version 13.x.
Please note that a silent install provides a method of installing system drivers and software for all currently supported Intel® Wireless Adapters without user intervention.
Also note that the information you can find on the following Intel article is intended for IT administrators, resellers, and integrators, and an advanced level of knowledge in information technology is assumed. This information is not intended for use by the individual end user.
You can find the instructions for performing the complete process from the following link:
Intel® Centrino® Wi-Fi Products: Silent installation of wireless drivers and PROSet version 13.x
I hope this helps
