FWIW, I to have this issue, I don't want to hijack these thread but I thought it pertinent to outline issues here too. I wanted to search for "Intel(R) Ethernet Connection I219-V" and this was the second on the list
However, my setup is somewhat different:
Laptop - HP EliteBook 1040 G3
BIOS update (01.08) - latest
Windows 10 64 bit, build 14955
Tried Driver version 22.214.171.124 (13/08/2015) and the latest Version 21.1 (September 28, 2016),
With the same issue. When the laptop is completely shutdown power off), then started from cold, the Ethernet NIC will detect a link of 1Gbs immediately and connect with no issue.
As son as the laptop is put to sleep, then woken up, the NIC will only say the link is 10Mbps, but not actually connect properly and pickup and IP address.
I have tried to disconnect the Ethernet cable, disable/re-enable the adaptor, it hasn't resolved the issue. Only a full shut down will cure the problem. .
Any further thoughts beyond what you have said above.
When you say Power Management settings, can you be more specific? Do you mean the Power Management setting of the NIC, or of the PC? In each case there are a number of possible options, which options should be adjusted specifically?
I should also note that after a reboot (with the latest driver) you get the opportunity to run different NIC tests, on the Connection, Cable and Hardware. All of these pass at all levels. After a wake from sleep however, when you run the test, you are informed that the device needs to be restarted, and the test fail. The only way I have found out how to do this is to reboot the machine.
Thank you for the reply. You can try change the power settings for a network adapter by going to the Properties of the network adapter, click the Power Management tab, try to check or un-check the "Allow the computer to turn off this device to save power check box. "
If you are connecting this laptop to a wireless router, another thing you can try is to change the channel of wireless router to non-overlapping channels.
Have you contacted HP* support as well? As there was instance in which HP* provided utility and fixed a disconnection issue, I am not sure if this is applicable in your case but it is recommended to contact the HP* as this is an onboard NIC on their system. http://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000006628.html?wapk...
Hope the above helps.
The drivers that were installed installed (126.96.36.199 - 13/08/2015, or 188.8.131.52 - 04/08/2016; the latter apparently being the version noted as 21.1 from your site : https://downloadcenter.intel.com/download/25016/Intel-Network-Adapter-Driver-for-Windows-10?product=... Download Intel® Network Adapter Driver for Windows® 10 - the 64 bit driver), do not show the normal WIndows Power Managment options. In other words there is NO "Allow the computer to turn off this device to save power check box. "
Instead, we see the following: (two screenshot show all options here):.
As mentioned, this is an Ethernet wired issue, not a Wireless issue, so changing wireless channels is irrelevant.
Contacting Intel in no my list, but sometimes is good to go straight to the source.
Thank you for the reply. Version 21.1 is the PRoset software version, the driver version will still be the one appear in the driver tab of your device manager.
I understand you are using a wired connection, the reason I asked you to change the channel on the wireless router is using non-overlapping channel on the wireless will have less interference on the wired connection.
Thanks. Please accept my confusion over you suggestions regarding wireless interference or wired networks. This is the first time I have really ever come across such a suggestion. I personally think you are reaching and this is not an issue. Be aware that the Ethernet device will work flawlessly from boot, it is only after a sleep is there an issue with diagnostic showing that it needs to be reset.
I also wonder if you could answer the question with regard to Power Management settings given the standard Windows options are replace with Intel customer driver settings?
Did some testing and we did not encountered said issue on our I219-V. Tried using default driver from Microsoft or Intel driver version 184.108.40.206 (From CD_driver 21.1 on our downloadcenter), no issue.
The power Saver option in our Power Management options are all checked excepts:
Reduce link speed during system idle
Wake on Lan options are all checked, except for the Wake on Link Setting
You may give the above options a try, but if this does not work, please contact HP* the notebook vendor for the driver that suits the system.
Sorry for the delay. For me, I made a few changes and this has seemingly fixed the issue. Uninstalling the latest Intel drivers seemed to have helped, although I'm also running fast ring Windows Insider releases, so updating things here might have fixed the issue. FYI, I also remove the standard Intel Wi-Fi driver.
Current Driver versions:
Intel(R) Ethernet Connection I219-V: 220.127.116.11
Intel(R) Dual Band Wireless-AC 8260: 18.104.22.168
