Hello,
I have a Intel 7260 wifi card in my arch system and I'm trying to get Wowlan working as it does in my Windows system from sleep (s3).
Running "ip addr" command, show my device name to be "wlp2s0". So initially I attempted: sudo ethtool -s wlp2s0 wol g
Resulted in:
Cannot get current wake-on-lan settings: Operation not supported. not setting wol
Uh oh, so I check "sudo ethtool wlp2s0" and all it shows is:
Settings for wlp2s0:
Link detected: yes
Running "lspci -tv" shows (only pasting relevent bit):
+-1c.2-[02]----00.0 Intel Corporation Wireless 7260
So I checked "cat /proc/acpi/wakeup" and it shows (pasting relevant part):
Device S-state Status Sysfs node
RP03 S4 *disabled pci:0000:00:1c.2
So I tried, "sudo echo RP03 > /proc/acpi/wakeup" from root. Even after enabling it, ethtool still only shows link detected and no packets will bring arch out of s3.
I'm not sure if this is a kernal, driver or what. I've reached end of my troubleshooting abilities, any advice on getting wowlan working?
Thanks guys

Ok, so I 've made some progress with the "iw" tool.
Issuing command "iw list", shows my phyname and that the device supports wowlan:
Wiphy phy0
WoWLAN support:
* wake up on disconnect
* wake up on magic packet
* wake up on pattern match, up to 20 patterns of 16-128 bytes,
maximum packet offset 0 bytes
* can do GTK rekeying
* wake up on GTK rekey failure
* wake up on EAP identity request
* wake up on 4-way handshake
* wake up on rfkill release
* wake up on network detection, up to 11 match sets
* wake up on TCP connection
So I try: sudo iw phy0 wowlan enable magic-packet
And looking at "sudo iw dev wlp2s0 wowlan show", tells me that:
WoWLAN is enabled:
* wake up on magic packet
Great! But now when I try to suspend (sleep) the system using "systemctl suspend", nothing happens. What a cruel twist of events, enable wowlan but can't go to sleep.
Any ideas?
Thanks

Whelp, anyone?

Can you see if something is inhibiting sleep, with
systemd-inhibit
I also know that if your wireless card is not PCI/PCI-E (it's USB, e.g.) wowlan may not be possible.

Did you ever find a solution for that?
