I have struggled a bit trying to understand while my Ubuntu 16.04 wasn’t waking up with the common etherwake commad.
I found the solution on this link:
you should disable Default option in Network-Manager GUI and enable only the Magic option. If you try this, then you should check if everything is ok opening the shell and issuing this command:Shell
12 sudo ethtool *<your_eth_device_here>*
You should see the line:Shell
12 Wake-on: g
If it’s not g but d or something else, something could be wrong.
Once done that, and verified with the command ethtool <myNetinterface> | grep "Wake-on:" , all started to work again 🙂
