If the system is not setup in the BIOS to "wake from LAN" from "sleep state" our first recommendation will be manually downloading and installing the latest LAN driver from our website:
If it is, please provide a more detailed description of the problem to better understand the issue you are having.
Thanks for the suggestion.
The BIOS LAN power setting selected is [stay off].
The OS is Win7 x64.
As I indicated in the original post the LAN disconnect occurs with the latest Driver Package.
However, the actual 82579V network adapter Driver Version 126.96.36.199 is the same for both ProWin7_64_17 and ProWin7_64_18 [PRO Network Connection for Windows 7] driver upgrades.
Respectfully, given the exactness requirements of computer system configuration and troubleshooting terms such as "latest" without the details of the specific driver numbers or driver package will be confusing or will become confusing as soon as a new driver release is available and the latest becomes the previous.
When I started this post the latest and now the previous driver was from the ProWin7_64_18 LAN driver set and the driver for the 82579V network adapter was [188.8.131.52]. This LAN driver package has recently been updated to ProWin7_64_18.1 while the release date remains unchanged from ProWin7_64_18 LAN package.
I just installed the newest ProWin7_64_18.1 LAN driver set and the driver for the 82579V network adapter [184.108.40.206] has been update from the driver in package 18. However in reviewing the Release Notes there is no reference to the specifics for the 82579V [220.127.116.11] driver changes.
I will report back as soon as I can determine any system performance changes.
