[OT] Wake on LAN
 

Anyone kicked a windows box into consistently waking up when sent a
Wake on LAN "Magic Packet"?

Windows Vista Home Premium, will wake up some times when the packet
is sent and the NAS always wakes up when sent it's packet from the
same program so confidence is high that the correct packet is being
sent and that the BIOS settings are right.

In typical WIndows fashion there are half a dozen or more settings
scattered across about three dialogues, all in different bits of the
UI. Some settings appear to interact.

Been fiddling and now the machine doesn't wake at all. It would wake
from "sleep" if you put it to "sleep" waited for a few seconds after
the power down the sent the Magic Packet. But if you left it "asleep"
for a period of time (FSVO: "period") it doesn't wake up.

Has anyone got a consistently working set of WOL settings for 'doze?

I have a vague memory that some routers can strangle the packets - WOL
has always been iffy over the internet.

This isn't across the internet it is within the same LAN subnet. The
only device between the Magic Packet sender and the target machine is
a non-managed gigabit ethernet switch.

I thought Wake On Lan was a feature of the hardware bios rather than the

The lan port on my desktop machine stays powered all the time (even in
S5), it will reliably WoL if it's in hibernate (S4), trouble is other
things seem to wake it up as well...

"Sleep" on the other hand seems somewhat problematic on this particular
motherboard (lots of forum posts), so I have that disabled :)

than

IMHO that's how it should be, send the packet, hardware recognises it
and instructs the PSU to power up, ie the same as pressing the power
switch to turn the PC on. What happens after that isn't relvant the
PC is on and should boot, wake up, come out of hibernation or WHY.

Windows has other ideas and must some how get between the LAN
hardware and the PSU hardware.

The lan port on my desktop machine stays powered all the time (even in
S5), it will reliably WoL if it's in hibernate (S4), ...

In theory, seen in many places on t'net, Windows won't come out of
hibernation (be that real hibernation or hybrid hibernation) only
sleep.

... trouble is other things seem to wake it up as well...

The LAN hardware can probably be configured to respond not only to
the really rather carefully constructed Magic Packet and/or some
other packets that are musch more likely to occur in normal traffic.
The LAN port on my target machine is configured for Magic Packet
only. Or was I wouldn't be surpised if windows has tweaked it to some
other setting.

Yes, The actual waking up is done by the ethernet hardware (when
configured in the BIOS), but the O/S or an app generally has to "prime"
the WoL ready to be woken as it shuts down, I've not really fiddled with
waking windows PCs, more Linux PCs ...

Just looked on this Win10 netbook,

under Device Manager, Network Adapters

the properties of both the WiFi and Giagabit NICs have on the Power
Management tab a setting for "Only allow a magic packet to wake ...",
that is a sub-setting which can be enabled if "Allow this device to
wake..." and "Allow the computer to turn off this device..." are both
ticked.

Yes it's nice hibernation works as intended on this board, shame sleep
dosen't work as well as it should... though hibernation is pretty quick
with an SSD anyway so it's not really an issue.

One thing that was annoyingly (and clearly by design) waking it, was a
DLNA app on my iPad, which just seems to try to power on anything it
sees (or has seen previously)...

Tisn't a "green" switch is it? Some combinations seem to do weird (but
probably intended) things - my desktop PC is now plugged into the
router, but when it was plugged into the switch* the link used to drop
to 10mbps if the PC was in "hibernate" and it sometimes took a second
(or more) tries to "wake up".
The NAS is still plugged into the switch, but that wakes up
instantly...probably becuase it dosen't have a "green" lan :)


*8 port gigabit "green" thing, don't remember the previous "non green"
one doing it.

in biological terms, hibernation is a deep sleep which last a long time.

OK, ta.

On our Macs here, there's essentially no difference between power-off
and hibernation, but functionally it's the same as what Win provides.

I don't usually bother shutting down my laptop (just checks settings.. )
have it set to sleep when the lid closes. The wife's macbook which also runs
Win7 in Parallels is used in the same way - no idea what the settings are
there.

Hibernation writes the ram to the drive and reloads it
back into ram when it comes out of hibernation.

On win 7+ there is also hybrid sleep..

it makes a hibernation file but just sleeps to allow a fast restart but
doesn't lose anything if the power goes.

I thought Wake On Lan was a feature of the hardware bios rather than the
OS.

The OS has to leave the NIC in a state where WoL can work, and an
OS (or rather a driver) which doesn't know about WoL may well leave
the card in a state where WoL won't work.

If you multi-boot different OS's, this can be a particular problem.

Also, some cards will run their own ARP when the system is powered
down so the WoL packet can be routed to an IP address (usually over
UDP) rather than using the raw ethernet address (which is not routable
across networks). This adds another whole layer to go wrong,
particularly in DHCP environments.

Not so much strangle, but lose....

For reliable WoL you might need to add an static entry (mapping MAC to
IP address) in the routers ARP table. Getting to that depends on how
locked down these settings are, or hidden in CLI.

e.g.
Wake on LAN From Internet Using a Thomson Router
http://npr.me.uk/wol.html

What otherwise happens is the computer powers off, the dynamic ARP entry
normally created on a lease is lost and then nothing wakes.

I used to use WOL via LogMeIn - the free version. Various changes to
LogMeIn stopped the free version and, I think, removed the WOL facility.
At the time, it was extremely useful but haven't needed it sufficiently
to seek out alternatives.
