Hello,
I am currently trying to set up wake on wireless lan on my new g751jy on Windows 8.1 .
On the Intel DuaI Band Wireless-ACC 7260 Properties, I checked
- "Allow the computer to turn off this device to save power"
- "Allow this device to wake the computer"
- "Only allow a magic packet to wake the computer"
Also in advanced :
- "GTK rekeying for WoWLAN" -> enabled
- "NS offload for WoWLAN" -> enabled
- "Sleep on WoWLAN Disconnect" -> disabled
- "Wake on Magic Packet" -> enabled

It almost works (I can wake it with a magic packet) except that it also has some insomnia at very precise timing :
It wakes up every 10 minutes (precisely at :02 :12 :22 :32 :42 :52) and then go again to sleep 3 minutes later (:05 :15 :25 :35 :45 :55 )
I am sure these wakeups are triggered by Wifi as they only occurs when Wifi is connected while going to sleep.

I am connected through WPA2 CCMP on an openWRT router.

Do anyone has an idea of what could triggered these wakeups?

Maybe the router pinging the computer to see if it is still on the network?

Thank you XOIIO,

I performed a tcpdump on my OpenWRT router and here is what I got when my laptop wakes up:

The tcpdump correspond with the router logs :

The last ping was almost 1 minute before, so probably not related to the wakeup

I also opened a thread on the OpenWRT forum as it is also related to my OpenWRT router :

ReDFoX2200 · ‎03-31-2015

are u waking it up from sleep mode or a shutdown?

XOIIO · ‎03-31-2015

It must be in sleep mode since it's using wlan

krys · ‎03-31-2015

I do it from sleep mode.
I tried from hibernate and shutdown but it's not working.

XOIIO · ‎03-31-2015

Yeah that's the problem with wake on wireless lan, the card doesn't have any power and the OS isn't running so it can't wake the computer.

I have tried WOL on the Ethernet card and it only works on sleep mode.

krys · ‎04-02-2015

Beeing only able to do WOL on sleep mode is not a problem for me as I never shutdown/hibernate my laptop.

But I still don't understand why it wakes up every 10 minutes when connected to my Wifi with WOL enabled.

G751JY wake on WLAN insomnia - wakes up every 10 minutes
