Public bug reported:
I'm dual-booting Ubuntu 18.04 and Windows 10. If I turn off my computer
with Windows, I can turn it back on using wol. However, if I turn it off
using Ubuntu the computer won't turn back on if I use wol.
These are my network cards:

This is what ethtool tells me about my ethernet card:
```
ignacio@ignacio-XPS-8930:~$ sudo ethtool enp4s0
Settings for enp4s0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supported pause frame use: Symmetric Receive-only
Supports auto-negotiation: Yes
Supported FEC modes: Not reported
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: Yes
Advertised FEC modes: Not reported
Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
MDI-X: Unknown
Current message level: 0x000060e4 (24804)
link ifup rx_err tx_err hw wol
Link detected: yes
```
And this is what happens when I try to activate wake on lan:
```
ignacio@ignacio-XPS-8930:~$ sudo ethtool -s enp4s0 wol g
Cannot get current wake-on-lan settings: Operation not supported
not setting wol
```
Finally, this is the infor about my distro:
```
ignacio@ignacio-XPS-8930:~$ lsb_release -rd
Description: Ubuntu 18.04 LTS
Release: 18.04
```
Thanks for the help!
