    Frequent Disconnect problem of Intel I219-LM NIC


      I'm using Intel NUC6i7KYK NUC, which has Intel I219-LM gigabit network card. I have the latest driver from Intel:

      Now the problem is the NIC frequently disconnects then reconnects. I have checked with 3 different routers and even used a CISCO  switch to see if the problem stops. But there is no luck. I have removed Intel's driver and used the one comes with Windows. The problem with Windows' driver is it cannot get me gigabit speed, only limited to 10MbPS. I even tried a very old-school trick (used that to keep Bluetooth connection on all the time) and set this up:

      But do not see any improvement. Fortunately when I use 3rd party NIC using USB3 port, works fine. So please suggest how to fix this.
