Wake on LAN not working on Optiplex 9020

Stephen,

Are the LEDs on the network adapter lit when you try WOL?

Have you followed the step-by-step on my blog?

Btw, it works from the Sleep mode. But not from complete shutdown.

My Wake-on-LAN doesn't work either. I recently bought the new Optiplex 9020 (NOT small form). I downgraded the BIOS to A02 and I am running Windows 7 Enterprise SP1. My older PC (when WoL was working smoothly) was plugged into the same port, so it is not a network issue. The network adapter is indeed I217-LM. Any tips?

1. BIOS: wake on lan(enabled) , deep sleep control(disabled)1. BIOS: wake on lan(enabled) , deep sleep control(disabled)

2. Windows 7: update the network driver(I217-LM) to the latest (e.g. 19.0)https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18713&lang=eng&OSVersion=Windows%207%20*&DownloadType=Drivers)

That seems to have done the trick! It works now. Thanks a lot!!

Don't like to repeat, but have you followed my guide?

UPDATE:  We just received an order of Optiplex 9020s (mini tower form factor) that were pre-loaded with BIOS A07.  Threw a basic Windows 7 image on one, updated BIOS settings as indicated in my earlier post, sent a WOL request to the machine, and........SUCCESS!  Looks like A07 has resolved the issue.

Hello,

Just to complete: as of today july 1st 2014, my 9020 was received with Bios A07 already installed and setting the BIOS parameters "Wake on lan" to LAN Only and "Deep Sleep..." to Disabled made the wake on lan working fine.

With "Deep Sleep..." set to factory default (Sx and Sy), the WOL was not working.

Best regards

Yes, maybe Dell needs to comply with some power saving requirements and therefore enables Deep Sleep in favor of Wake-On-LAN? Whatever the reason is, it is extremely annoying that this is not clearly documented.

Also, you are probably using Windows 7 if this works for you with BIOS settings only, in Windows 8.x you additionally need to go to Windows power management and manually DISABLE "fast startup" as I described here:

I have to admit this is really frustrating. I have a lab that uses about 40 of these and I still can't get WOL working.

We image our machines using the latest CABs from Dell using SCCM 2012.

We're using 32bit Win7 and I've followed all the BIOS recommendations here including: Disable Deep Sleep, disable S3 sleep. Disable power management in the O/S on the NIC driver.

I've even tried WOL, Lan only, with PXE, etc, etc. Even tried UEFI on and off...

Here's the weird thing. If I adjust any 'power management' type setting I will get 1 WOL boot off of the PC. I've verified this on 3 different 9020's. It will only work once, then it's back to not working, and the time it works, it tries booting off the network! Even if I change the boot order, or remove devices from the boot order. (By this time WOL completely breaks anyway so it's a broken experiment.)

Even disabling  power management in the NIC driver on the OS let's me get one (network only) WOL boot. Very frustrating...

Thank you for your response. I figured out what was wrong in a round about way....

First off, the BIOS version was A07 (as shipped), mini towers.

After taking your advice and resetting the BIOS and then going into Win 7 and re-enabling the changes I had made to the NIC power management, the WOL worked!

So I made the same changes to a few more PC's, cycled the BIOS' and they did not work! It was at this point I realized I have to not only cycle the BIOS but let the OS load. If I don't let Windows 7 load, the machines don't WOL.

I confirmed this on several PC's even with different BIOS changes, and they all worked IF I let the OS load. This finally sheds light on why I was chasing so many red herrings so to speak. I'd think some goofy change made it work, when in reality it was the OS load that would give me a 'false' positive.

Thankfully the whole lab is now responding, but I feel a bit of a fool for chasing ghosts for 2 days in that lab!

Thanks again for the suggestion.

It looks like it is important that the OS shuts down the PC and leaves the network card enabled. This is similar to Windows 8 where you need to turn off fast startup to make WOL work. Things get so complex with these new OS and energy saving stuff - it is a nightmare!
