To enable Wake-On-Lan (WOL) on your HDA

1. Enable WOL in the BIOS

2. Boot Fedora. Open a terminal and execute su to get root access

3. Assuming your LAN interface is on eth0, run ethtool eth0

The output will look similar to this:

bash code
[root@localhost ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes ​


4. Look for a line similar to this:

       Wake-on: g

This means that WOL by magic packets is enabled on that interface.

If the line is

        Wake-on: d

then WOL is disabled. Activate it by running ethtool -s eth0 wol g

If you don't find any line containing Wake-on at all, then your interface card doesn't support WOL, or the OS cannot detect it , or it's not enabled in the BIOS.

Check the ethtool man pages for a full explanation of the Wake-on options

  • Note: Some legacy drivers forget the setting during boot. Run ethtool eth0 again if you suspect this is the case
