I have a new computer and after being away from the computer for a while (a few hours), the network card lost it's IP address. The computer was not sleeping or hibernated. I restored the connection by opening a command prompt, running ipconfig/release, then ipconfig/renew. Here are some specs:
OS - Windows 7
Motherboard - Gigabyte GA-X99-UD3P with on-board Intel LAN NIC
Driver - Intel Ethernet Connection I218-V (Version 18.104.22.168 dated 11/24/2015)
What I want to know is:
A. Am I using the correct driver?
B. If so, is there any settings I can change to correct this issue?
Thank you for contacting Intel.
