Hi,
I have a B150M-DH3 F6 gigabyte board with a intel i219-v onboard NIC. Using windows 7 x64 pro. Clean install on 01/01/2017.
Symptom :
When computer resumes from sleep mode, link speed changes to 10mbs and I lose my network connection.
I tried :
- newest intel drivers
- rolling back drivers
- turning off all power saving options in NIC preferences
- forcing 1gbs speed in NIC preferences
- forcing 100mbs speed in NIC preferences
- fiddling with BIOS settings (no power saving settings in BIOS for onboard NIC)
All to no avail.
I usually need one (sometimes two) reboots to fix the problem.
Please help!

Found a workaround :
if I wake up from sleep by using keyboard or mouse, link changes to 10mbs, stays stuck there and no internet connection until reboot
if I wake up from sleep using case power button, everything works fine
Any explanations as to why this might be?

Hi Nerfolt,
Thank you for the post. I would suggest you to un-install Intel driver then try check with Gigabyte for their latest customize driver. Have you tried upgrading the board BIOS?

Hello,
I tried both the driver on the bundled cd-rom and the driver on the gigabyte website, to no avail. Both are intel drivers as far as I can tell by the way.
The latest revision of the motherboard bios only adds support for newer CPUs so I doubt it'll change anything with the network controller.
Regards,
N
