I forgot to mention: Windows 7 64bit SP1 Home Premium.... Intel DX58SO
Problem solved. Use the update from "Ethernet Components" which is ' Network Adapter Driver for Windows 7 ' @29.2mb instead of the drivers recommended from "Desktop Boards" which is "LAN: Intel Pro Network Connections LAN Driver" @28.8mb. Both have the same version number (16.4) and
file version 22.214.171.1244. The difference is...one works and the other doesn't. So looking for updates by desktop boards is giving the wrong info.
