Enabling WOL

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

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 eth1 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.

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
