Hi wb_Intel,
I have tried the version 20 release and the problem is still there. This is not surprising, as the i218-LM driver has not changed - within DeviceManager it is still shown as v12.12.80.19 dated 29th Sept 2014. In fact the release notes for version 20 only state a change in the 'teaming name', which is clearly nothing to do with the problem I am experiencing!
My question still remains - "what has changed between v12.6.47.1 and v12.9.16.0" ???
Regards,
