| Wake my PC Remotely works but only within 1 minute
Dear DSLReports and all who may help,
I found this service, "Wake my PC Remotely" at (www.dslreports.com/wakeup) very effective for waking my desktop PC (WinXPSP2-Home, Award Modular BIOS v.6.00PG) from my laptop via the Internet (using my desktop PC's IP, MAC and UDP port 9 on my Linksys WRT54GL router).
After waking, I use a software to remotely control my PC from the other parts of the world.
The (BIG!) problem is that the PC will wake only immediately or ~ 1 minute after I shut the system down.
Have you any idea why is it so? What changes in my PC during this short time after the system is closed?
Please provide any information.
Thank you. |

| On the WRT54GL, you must forward the incoming packet to the broadcast address (usually 192.168.x.255) and not the specific IP of your computer, which I'm going to guess is how you have it set up.
Once your computer is off, the network switch inside the router (or anywhere else) quickly forgets that that IP is tied to the MAC address of your network card. |

| Thank you for this advice but sorry, I'll risk stretching your patience.
It sounded promissing and so I changed 192.168.1.3 to 192.168.1.255 (in NAT/QoS > PortForwarding tab in DD-WRT v.24 Std.) and the effect was as before: my PC wakes if I send the waking signal (MagicPacket?) to my router's static IP address and my PC's MAC address in 10 - 50 seconds but it keeps sleeping if the time is longer then ~ 2 minutes.
So, what more should I change in my router's settings? or BIOS (PME is enabled...)? or ...?
I assume there's something to be set in DD-WRT but there are so many variables there that I have just a dim idea of.
It looks like the only option for me is to rely on someone giving me a complete set of settings (ideally the router's config. *.bin file) that I could just follow like a parrot or monkey 
Thanks. |

I haven't had any issues with WOL from either DSLR or by browsing to the Remote admin pages for the DDWRT and issuing the WOL from there.
DDWRT will run on the GL. In DDWRT you can set a STATIC DHCP for a computer. Once done, you can preset the WOL for that PC.
Try that and see if you have the same issue. If so It's the PC. if not, it's the Forwarding.
Your PC may not be maintaining a sufficient power level for the Ethernet port to stay operational. the "minute" that you do get could be powered from capacitors. |

| said by RevMortis  :If so It's the PC. if not, it's the Forwarding. That is a good idea. You can also try waking your PC with your laptop when it is on the LAN to eliminate the router as the issue. You'll have to use a locally installed WOL program on your laptop for this test. |

Hi, RevMortis, thanks but your explanations contain terms & ideas I am not familiar with.
I'm just a simple electronics eng. and so I understand your mention on caps on my motherboard but not much of the rest.
I am able to do and have done things such as: flash the router with DD-WRT v.24 Std., set Repeater Bridge on my second router.
Let me ask details alongside your text, in CAPITALS:
Your PC may not be maintaining a sufficient power level for the Ethernet port to stay operational. the "minute" that you do get could be powered from capacitors.
DO I HAVE ANY CONTROL ON GIVING MORE POWER TO MY ON-BOARD ETHERNET "CARD" - IF THAT'S WHAT YOU MEAN?
*************
I haven't had any issues with WOL from either DSLR or by browsing to the Remote admin pages for the DDWRT and issuing the WOL from there.
WHAT'S "Remote admin pages"?
I HAVE NOT SEEN SUCH ON DD-WRT.
*************
DDWRT will run on the GL.
I KNOW, I FLASHED MY 2 GL's WITH THE FINAL VERSION 24, "Mini", AND THEN "Standard" - WITHOUT ANY PROBLEMS.
*************
In DDWRT you can set a STATIC DHCP for a computer.
PLEASE TELL ME WHERE DO I SET "STATIC DHCP", IN "Network Address Server Settings (DHCP)" SECTION? THERE IS ONLY ONE PLACE THERE TO ENTER A 4-PART DATA, LOOKS LIKE IP-ADDRESS IN "WINS" ???
*************
Once done, you can preset the WOL for that PC.
WHAT DO YOU MEAN "preset the WOL for that PC"? IN "ADMINISTRATION" > "WOL" TAB IN DD-WRT?
AND IS THIS "WOL" TAB NECESSARY TO SET ANYTHING IN AT ALL?
I THOUGHT I SHOULD ONLY FORWARD, SAY, PORT 9 UDP TO MY PC's ADDRESS, SAY 192.168.1.3 OR, AS PetePuma SUGGESTS, TO 192.168.1.225 - BUT IT ALSO DOES NOT WORK LONGER THEN THE 60 SEC. OR SO, THAT, AS YOU SAY, CAPACITORS ARE STILL KEEPING ETHERNET CIRCUIT(S) ALIVE...
AND I HAVE JUST ELIMINATED MY PC AS CULPRIT: I SHUT IT DOWN AND SUCCESSFULLY WAKE BUT NOT BY "MAGIC PACKET" BUT USING "POWER-UP" FUNCTION OF THE APPLICATION I MENTION BELOW - BUT FROM MY LAPTOP WIRELESSLY CONNECTED TO MY HOME NETWORK AND NOT TO A NEARBY HOT-SPOT AS I AM TRYING TO DO TO BE ABLE TO WAKE THE PC IN FUTURE FROM ANOTHER CONTINENT.
SO, IT'S NOT THE PC's NIC BEING UNPOWERED. AS I SEE IT, IT IS POWERED ALWAYS, FROM THE ROUTER, VIA ETHERNET CABLE.
*************
Try that and see if you have the same issue. If so It's the PC. if not, it's the Forwarding.
FORWARDING IS OK, I USE AN APPLICATION (AnyplaceControl)TO FULLY CONTROL MY DESKTOP FROM LAPTOP OVER THE INTERNET
AND IT WORKS VERY WELL BUT THE ONLY PROBLEM IS WAKING THE DESKTOP FROM OUTSIDE MY HOME NETWORK.
*************************************************
Well, sorry but there has to be a simple solution that can be applied by just following clear step-by-step instruction, just as I did to set, unbrick, flash, etc. my routers.
Thanks and please help if you can. |

| Well, dear all, I'm dissappointed, you clearly ignore what I wrote, what I can do and cannot and are giving me advices to do the most obvious things I tried already on my own, such as "http://www.dd-wrt.com/wiki/index.php/WOL" - absolutely useless in my situation.
A step-by-step instruction would be "in DD-WRT v.24Std. open Setup>Basic setup...' etc.
OK, I'll try elsewhere. |

| Looks to me like you had two knowledgeable people making a sincere effort to help you, including asking some troubleshooting questions and offering links to the proverbial step-by-step.
It's your choice if you want to throw up your hands and walk away in frustration. If you demand immediate results, you may want to hire someone to configure it for you.

I have tried to do the same thing with my PC however sometimes the magic packet sent would lockup my comp upon the startup sequence. I did set my router to broadcast udp port to my specific comps static ip address but again it was hanging it. So I figured the fans might be running the hard disks wind down after 20 min would be bearable power savings that I decided just to leave my comp on all the time. I even set in the BIOS for a restart when a power failure occurs. I don't mean to sound like a smart ass but could you just leave the comp on all the time and just set up some power saving features? Or is security an issue for you? If its security and you think that powering down your comp is some safety feature well I would have to say if someone really wanted anything on your comp they would know to broadcast the magic packet over a lot of routers just to turn on sleeping computers and then go about their business, highly unlikely because there are lot of computers out there. Sorry I'm ranting. Good luck and cheers! |

Alright Let's back up a bit. if the problem is Waking from outside the home network after an elapsed amount of time then there can be 3 causes: 1 - the Forwarding instruction may be expired (so the Magic Packet may be dropped), 2 - The DHCP assignment can be expired so that the Packet doesn't reach the right IP/computer, 3 - The Computer may not be listening.
To see if it's problem #1 (Lost forwarding instruction), then we need to see if we can wake the machine from another source that is internal to your LAN. Either we need to get A) WOL software that can broadcast magic packets on some other computer on the LAN, or B)have your Router create the packets.
1A - Google "WOL software" - download and install it on a computer connected to the network other than the machine you want to Wake remotely. Verify that it works in the "one minute" interval. Repeat after the long interval and report back.
1B - Use DDWRT's WOL page to send the Magic Packet.
Checking Problem #2 (Lost DHCP) - Again Multiple options:
2A - Change your forwarding to forward to the Broadcast address IE: 192.168.XXX.255 -- where XXX is your LAN Segment.
2B Setup Static DHCP for that Mac address. (I don't remember the exact steps off the top of my head, I'll get back to you if you want to try this.)
Checking #3 (Computer is the Issue)
On my computer there are several different settings in the BIOS that needed to be set for WOL to work properly (AMIBIOS). I know you have it working in some situations, but WOL can be tricky. The WAKING device must be in a powered receptive state to generate WAKE request to the system. When your Computer is OFF (s5 state), do you still see the link activity lights on the LAN card/port/etc on the computer? If not, We need to get it that way.
Digression Power states - There are 6 different Power states* for a computer ranging from S0 (All on) to S5 (all off). Progressively each state uses less power than the ones before. In a generic nutshell:
S0 - All on
S1/S2 - Screensaver/Suspend - some peripherals are off (monitor, HDD, etc) but the computer is still running full steam.
S3 - Sleep - The current state of the Computer is written to Memory, all the Peripherals are turned off (Monitor, Display, HDD, USB devices etc AND the CPU is turned off.
S4 - Hibernate - The current state of the Computer is written to Disk and the computer effectively is turned off.
S5 - Off - The computer is will reboot when turned on.
* = Some devices may remain powered beyond when they would usually be turned off per the nutshell if specified in the BIOS that they need to remain on to generate a Power On event.
Settings in my computer for WOL to work in Standby or more):
Power Management/Wake Events/Wake From PME=Enabled
Power Management/Standby State=S1 (or if set to S3 also set Wake USB=Enabled and Wake VGA=Enabled)
Integrated Peripherals/Onboard LAN = Enabled
Integrated Peripherals/Onboard LAN/Onboard LAN PME=Enabled
I'll assume you're also using onboard LAN since you used quotes. If not, let me know. The Power state you wake from may be turning off the LAN "card".
A few more answers:
----------------------------------
WHAT'S "Remote admin pages"?
I HAVE NOT SEEN SUCH ON DD-WRT.
IIRC, on the administration tab there is a checkbox to "enable remote management" If enabled, you can set the port for you to connect to.
*************
DDWRT will run on the GL.
I KNOW, I FLASHED MY 2 GL's WITH THE FINAL VERSION 24, "Mini", AND THEN "Standard" - WITHOUT ANY PROBLEMS.
Wonderful! 
*************
In DDWRT you can set a STATIC DHCP for a computer.
PLEASE TELL ME WHERE DO I SET "STATIC DHCP", IN "Network Address Server Settings (DHCP)" SECTION? THERE IS ONLY ONE PLACE THERE TO ENTER A 4-PART DATA, LOOKS LIKE IP-ADDRESS IN "WINS" ???
I don't remember off the top of my head which page it was, and I don't have access to it at the moment. I'll have to get back later.
*************
Once done, you can preset the WOL for that PC.
WHAT DO YOU MEAN "preset the WOL for that PC"? IN "ADMINISTRATION" > "WOL" TAB IN DD-WRT?
AND IS THIS "WOL" TAB NECESSARY TO SET...
Actually this is a bit of a divergence. It's not necessary if you can test with regular WOL software from another computer INSIDE your LAN. The goal was to provide an alternate "Magic packet" source that could be used.
*************
Try that and see if you have the same issue. If so It's the PC. if not, it's the Forwarding.
FORWARDING IS OK, I USE AN APPLICATION (AnyplaceControl)TO FULLY CONTROL MY DESKTOP FROM LAPTOP OVER THE INTERNET
AND IT WORKS VERY WELL BUT THE ONLY PROBLEM IS WAKING THE DESKTOP FROM OUTSIDE MY HOME NETWORK.
I'm still not convinced, the computer will automatically re-acquire the same DHCP lease on expiration the first time there is network traffic. The fact that your computer is turned on may be clouding that issue.

Hope this helps! |
