I have problems with wired internet connection.

ifconfig
enp3s0    Link encap:Ethernet  HWaddr 70:4d:7b:31:40:67  
          inet addr:10.129.45.123  Bcast:10.129.63.255  Mask:255.255.224.0
          inet6 addr: fe80::ae56:1e47:3b4f:9147/64 Scope:Link

          collisions:0 txqueuelen:1000 
          RX bytes:6204 (6.2 KB)  TX bytes:6856 (6.8 KB)

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1

          collisions:0 txqueuelen:1 
          RX bytes:48976 (48.9 KB)  TX bytes:48976 (48.9 KB)

And this is what I get with ethtool

ethtool enp3s0
Settings for enp3s0:

                   drv probe ifdown ifup

With sudo, just two lines are changed

Supports Wake-on: pumbg
Wake-on: g

What does this mean?

How to change my wol settings? WOL stops working after booting Ubuntu

Should I change script from the above link?

  • Is it turned on in the BIOS/Network Card itself? – Ziazis May 17 '17 at 09:27
  • @Ziazis I do not know,how to see this? – MikiBelavista May 17 '17 at 09:32
  • During a boot go into the BIOS settings via the shortkey that is provided. The same goes for an external Network card if you have one. There should be an option if available, usually in the category "power" or something like that. Since every BIOS is a little different you have to look through it and see if you can find it. Another option you can just try sudo ethtool enp3s0 so you have permission to see the wol options. – Ziazis May 17 '17 at 09:42
  • @Ziazis I think that I have UEFI on my desktop. – MikiBelavista May 17 '17 at 09:43
  • Wake on: g usually means wakeonlan is enabled. – muru May 17 '17 at 10:08
  • ^what muru said. If you want to turn it off sudo ethtool -s enp3s0 wol d – Ziazis May 17 '17 at 10:15

To use WoL features you first need to make sure that it is enabled in your BIOS/Network Card.

If it is enabled you can use the ethtool to check the current settings of it.

If you are missing ethtool you can install it via sudo apt install ethtool.

Once you have it available you can check your settings via this command:

sudo ethtool [yourInterface] e.g. sudo ethtool enp0s3

Look for the line Wake-on: d

If the value is "d" you can enable it with this command:

sudo ethtool -s [yourInterface] wol g e.g. sudo ethtool -s enp0s3 wol g

If the value is "g" you can disable it via:

sudo ethtool -s [yourInterface] wol d e.g. sudo ethtool -s enp0s3 wol d
