Wake on pattern match? How do I do it? Pros and cons?

[leito360]

Hi!

I mounted a netbook as VPN, and I can totally control it using TeamViewer, even turn it off.
The big issue comes when I have to turn it on, since it seems the BIOS is so basic it doesn't support WOL.

Reading through the internet and looking through the options of its LAN adapter I found it also supports Wake on Pattern Match.

So this means that I can wake up the netbook from a suspended state remotely?

How do I do that?

What issues could I expect?

P.S.: The netbook is a variant of Nobi 10.2 Clamshell called Exomate "Exo X352", it uses Phoenix's BIOS
MPPNV10A.86A.001F.2010.0308.1453

Thanks

The link is good and explains it well. Pattern match can work, but pretty much any ARP/NetBIOS will wake it. That means, most likely, its going to be waking fairly often just from routine traffic on your LAN.

Wait, your device supports WoL via pattern match but not magic packet?

And azazel1024 is right: pattern match is very, very susceptible to unwanted wakeups. I did a test of wake-on-pattern-match once on my home network, and and I think the longest the system was able to stay asleep was something like 3 minutes, before it woke up again, and it often woke up just seconds after going to sleep.

In my experience with a couple of different manufacturer NICs I've seen anything from about 15s to about 10 minutes between wakes with pattern match. I've never been able to get longer than 10 minutes between and it is the single biggest reason for anomalous wake from sleep I've seen in systems where all of the various "wake on lan" boxes are ticked by default on a system.

My BIGGEST annoyance (only because I forget, and it makes no sense) is why in Windows 8 and 8.1, you MUST disable hiberation and the hybrid start to allow WOL from S5? It just makes no kinds of sense to me. I think almost everytime I've reloaded my desktop I had forgotten that little gem and spent a couple of hours diagnosing why I couldn't get my server to turn on my desktop to back it up nightly.

Oh right, because Windows.
