Same problem here.
One tagged VLAN (6) and untagged VLAN. After every reboot the untagged VLAN doesn't work until I disable and re-enable the Untagged VLAN virtual adapter. The VLAN6 doesn't present this problem and can ping other hosts in the same VLAN.
NIC is connected to a Cisco switch with the following config:
nwcore2# sh run | s 2/0/39
description AURELIO (0B39D)
switchport trunk allowed vlan 1,6
switchport mode trunk
spanning-tree portfast trunk
spanning-tree bpduguard enable
Let me know if you need any information to try to detect the issue. As ziesemer I have no dump as the system doesn't crash.
The adapter is I217-LM.
I am using Windows 10 Anniversary Update and all available patches installed.
The problem only appears when computer starts or reboots. I had "Fastboot" enabled and powering on the computer from hybernation didn't reproduce the issue.
Can you share the SSU log? You may download the tool at https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility
Please, find the SSU logs attached.
I've collected two sets, one of them just after reboot with network connection broken and the second one after disabling-enabling the NIC and network connection working again.
Please check the "events" tab for the untagged vlan in the property of the network adapter for possible errors and share to us. Can you try check with system manufacturer for similar case and workaround?
