The smart network software was pre installed on my Windows 7 PC. It continued to work with Windows 10. I can't find any version number for it.
There is a download page http://esupport.sony.com/US/perl/swu...1&os_group_id= on the Sony site that may help.
Sorry I can't be more help.
I have a Vaio VPCSE2 and the issue I had was that the login screen did not give me any fields to enter my credentials and log in. The computer is pretty useless if you can't log into it. Only thing I could really do is access some small icons in the lower right for wireless connection or accessibility options.
After much testing I found if booting it with the wireless switch off, I would have a login screen. I could log in using cached domain credentials but the login scripts would not run because once I logged in and flipped the switch, it was too late. Because it seemed this was linked to the wireless switch, I updated to the latest Intel wifi drivers for the 6325 advanced-n card in the laptop. It still did not correct the problem. I use the built in restore tool to go back to my currently working Windows 8.1 install (which was a clean install at the time - laptop originally shipped with 7 Pro on it).
