RSSRealtek’s network controller deep sleep mode issue
Oct 29
As I’ve noticed a fair bit of visitors interested in my post of Windows 7 and Network Controller Deep Sleep Mode problem, I thought I should write a “clean” version of the post (basically the fix for the problem minus my ramblings 
)
The problem starts when the computer goes into sleep/standby mode, a few components of the PC including the network controller (or adapter) are turned off. The issue occurs when the PC wakes up and power to everything is restored. The network controller doesn’t come on and as per Realtek installation message:
The RealTek Network Adapter/Controller was not found.
If Deep Sleep Mode enabled Please Plug the Cable
The best fix is to reset the motherboard and the best way to reset your motherboard is to remove your RAM chips. Leave them out for some time (in my case 30 seconds) and put them back in. And that is all! The motherboard will be reset and the network controller will come out of deep sleep mode!
Note: If this doesn’t work, leave the RAM out for good 10 minutes. Leaving the RAM out longer has worked for some people (see comments below).
Note 2: For laptops, removing the battery for 5-10 minutes has worked for a few.
Note 3: If nothing works, turn off the system and plug in a external hard drive (or a USB thumb drive) and then turn the computer on. Once on the desktop, Windows will try to install the external hardware. This, in some cases, has worked and wakes up the network controller.
Once you have it working, to make sure the network controller doesn’t go into sleep mode again, try this:
- Open Device Manager by:
- Go to Start
- Click Control Panel
- Choose System and Security
- Click Device Manager (under System)
- Open Network Controller properties by:
- Double-click Network adapters to expand it
- Double-click the Realtek Network Controller
- Turn off Deep Sleep mode by:
- Choose the Power Management tab
- Untick “Allow the computer to turn off this device to save power”
Doing this will make sure the network controller is not put in to sleep mode till someone fixes the issue!
Finally, if something does work you please post the Motherboard/Laptop model and the method that worked to help others!

Thanks man! I’ve been struggling with this for a while and didn’t know what the issue was. I’ve just disabled deep sleep and we’ll see if it fixes things.

Thanks for the tutorial, but I was unable to enable my Realtek ethernet controller. I removed RAM and cmos battery with no success. The motherboard did reset but LAN controller didn’t work. Then I thought, maby it’s because I had deep sleep turned on in BIOS while installing win XP, so I reinstall WinXP, now with deep sleep disabled. The result was the same. Two days of trying made me a bit mad, and I began to think that the ethernet controler is broken or something…. But then I inserted the live Ubuntu disc in the CD-ROM and the ethernet controler magicaly started to work :S
I’m very confused, please help if somebody know what’s wrong…
I have: Foxconn barebone nt435.

1. Disable the Windows Sleep mode then shut down the PC
2. Unplug the power and remove any RAM (including Graphics Card).
3. Remove the Motherboard battery and Unplug the Ethernet Cable.
4. With everything still unplugged, press the power button to fully drain the PSU.
5. Wait a while. (I actually fell asleep and continued the following day)
6. Plug in and turn on the PC without RAM or Graphics or Ethernet cable then turn it OFF.
7. Unplug power and replace the RAM (Graphics too) and the Motherboard battery
8. Plug in the power (not the Ethernet cable) and turn it on and boot windows.
9. Shut down the PC, then turn the PC on again and Plug in the Ethernet cable.
10. Allow windows to boot.
11. You should have connection.

@Seth… I tried step by step and still not have network

Just got my Toshiba M900 from repair, re-installed Win7 64 to start fresh and now I’m getting the same errors above.
Can’t remove RAM chips and CMOS since they’re not accessible without dismantling tha laptop. I’ve plugged a cable and the green light stays on.

I started having this issue last Sunday. I ordered a PCI ethernet card, and today the card arrived. I unplugged power to the system, plugged in the PCI card, plugged the power cord back in, and restarted the system. Windows 7 then re-installed the drivers for the Realtek on-board ethernet controller. I have an Asus M4A89GTD Pro USB3 motherboard.
Mar 30, 2012 @ 18:36:20
Your’e the man! It worked. Same by me. The same Motherboard! Just started 2 go crazy! Thanks man! Blessings!
Dec 04, 2011 @ 19:36:54
love you!!!!!!!!
I thought my Ethernet adapter is short circuited, cause i was not able to see it anywhere linux, windows but this post saved me….
you not just saved my huge time which i would have lost by giving it to service center , but also saved me from embarrassment when i would have gone to service center by taking my motherboard alone , and it would have worked just fine ….
thank you very much!!!!!
Dec 07, 2011 @ 09:20:24
where do i disable the sleep mode on my mecer desktop
Dec 08, 2011 @ 19:20:22

Dec 09, 2011 @ 19:11:12
I’m having the same problem and have tried everything above with no results. Running an asus m5a7bl-usb3
Dec 10, 2011 @ 05:43:23
unplugging the power cord then pushing the start button a few times to drain any capicitors then putting my dongle in a usb jack the computer has not seen it in then starting the computer took it out of deep sleep amd the computer reinstalled the dongle and the ethernet controller then I reinstalled the realtek drivers after getting them off the web on a working computer but them on a portable drive and installed them then let the troubleshooter finish the job and all is working now
Dec 26, 2011 @ 14:20:41
I tried everything but nothing worked
Dec 26, 2011 @ 16:20:30
I tried everything on this page. But nothing worked. So i looked to my motherboard checked everything and downloader correct drivers. Just choose correct drivers, correct REV, correct windows and bit’s and everything will be OK!
Jan 13, 2012 @ 18:31:07
Thanks for the post. I’ll see if it works.
Jan 19, 2012 @ 10:42:05
thank you very much – this solved it right away.
The network interface of my ASUS mobo suddenly disappeared after I enabled the hybrid standby in the energy options of win7 …

Hi, was there had done all of that above – without putting apart computer – in my point of view it`s kind of silly- U can reboot your card from system and it is clearing card`s ram- that is enaf , the solution for that issue should be diffrent. Some driver update or from realtek or microsoft – i do belive that drivers are “bitting” eachother – so that is causing problems.
I`d forget to mention that I made much more of that what I found in internet – with same result.
Most important thing is that I`m able to establish internet connection from cmd mode, but win7 is showing in that some time no internet connection buhahaha.
Rltk 8169D/8111D win 64-bit win7uck gigabyte P7-H55 M – SI – it is obvious that I used information from DOS box to set it on “hard” ( like IP adresess ) in windows / so I was trying to get online help from another comp. from microsoft – they don`t help guys from my region – buhahaha I got stuck with it . So If someone got real solution please – GIVE IT TO ME
Feb 03, 2012 @ 14:01:07
As “silly” as it may sound, this has worked for me and a lot more people quite a few times. For some people, even leaving the power unplugged for a few hours have worked.
Jan 29, 2012 @ 02:21:43
Thank you…..only just enabled the settings but logically this should work.
Feb 07, 2012 @ 08:16:49
Same issue for toshiba satellite c660-1ch, controler was not found in windows 7 or linux because was put to sleep, even changed bios ver. and no succes but..
Solved by removing battery for 15 minutes, and meanwhile i pressed a few times power button to remove any lose currents.
Feb 22, 2012 @ 04:34:58
I went to ADD NEW DEVICE wizard and tried detecting the adapter, it worked for me after restarting the computer once.
Feb 24, 2012 @ 19:25:47
just check the very very right driver version for you current O.S that’s worked for me ,
Feb 25, 2012 @ 09:15:08
HP Pavilion dv7 notebook:
Enter Bios and DISENABLE lan sleep mode. Works instantly.
Mar 24, 2012 @ 08:32:05
I cannot find it in BIOS
((. I checked but there is no option at all with LAN in my BIOS. It’s only with Card Reader / 1394 controller. But not with LAN ! I have a pavilion dv7 and I get crazy with this issue. When I set up the computer to hibernate, if I close the lid, than everything is ok => when I lift the lid I get internet. When I set up the computer to sleep when closing the lid than …I don’t get internet. I have to restart my laptop….
On both cases I disabled the “Allow the computer to turn off this device to save power” ‘tick
Plz, plz come with real solutions…
realtek pcie gbe family controller driver; win7 – 64bits
Mar 24, 2012 @ 20:34:17
You will need to go to the website of HP and update your Realtek Ethernet driver. If that doesn’t work, you will need to go Realtek’s website and try their driver.
Feb 28, 2012 @ 03:01:51
Thanks a lot Adeelejaz. It works for me thanks again.
Feb 29, 2012 @ 19:05:26

Mar 06, 2012 @ 16:59:36
Thanks…i was going crazywhith this…fwindows wouldnt reconize ethernet controller…

Many thanks
Mar 06, 2012 @ 17:03:38
I did this on my shuttle sh55je and works nice
Mar 11, 2012 @ 22:47:51
I have the Realtek 8111E onboard controller on my MB (Asus M5A97). I just rebuilt my machine with W7 64 bit. I believe I am suffering from this same problem, however I have never gotten the LAN card to connect to the internet. I have tried everything. Sometimes it shows up, sometimes it doesn’t.
What is really strange is that I have a PCI wireless card connected as well, it takes a while – but WILL connect to the internet. I have a 12mb DSL ISP. All other computers/devices in my house get about 10mb/sec connection, my wireless card only gets about 0.5-1 mb/sec. Do you guys think this is a related issue? I don’t even know where to start.
Appreciate the info.
Mar 12, 2012 @ 12:03:54
I don’t think so its the same issue you are having. We couldn’t see the network controller in Device Manager at all. It was as if network controller didn’t exist.
Mar 14, 2012 @ 02:39:39
I have the same problem, i can not even find the driver. Have you found a solution?
Mar 14, 2012 @ 10:31:34
Have you actually bothered to read the post? It has more THREE solutions! The comments are littered with people telling how they fixed it!
Mar 14, 2012 @ 08:01:57
thanks a lot! removing and placing the battery fixed it!
gracias!
=)
Mar 14, 2012 @ 12:50:26
i tried everything but nothing worked except one thing…i installed the driver manually and used the driver from the OS(win7)…5days without ethernet so i was so happy when it worked
the way i did it is this:
1.downloaded driver from MB manufacturer
2.Read a readme file on how to install manually and read what correct driver to install
3.tried to find the driver from the files i DL from the manuf.but didn’t fint it.
4.looked at the default drivers windows has(manufacturer realtek)(win7 has also realtek semicondctur listed but mine was only realtek)
5.get a warning that i shouldn’t install because it may not work etc etc.but i install anyway and the driver installs and suddenly my ethernet works again
this was done after a fresh install of win7 and mb drivers and vga drivers installed

Hi, Adeel Ejaz i have a Gigabyte Z68X-UD3H-B3 i remove the ram remove my gpu remove the board battery i follow al the steps but i don have any networks adapters, can you help me?
Mar 28, 2012 @ 03:39:55
if i Format my hard drive can fix this?
Mar 30, 2012 @ 22:15:39
It looks like your problem is something else. I don’t think formatting will fix it. Have you tried leaving your computer unplugged for a few hours?
Apr 01, 2012 @ 07:45:56
I can confirm that this works!! I spent hours wondering why my network controller just “disappeared” from device manager until I stumbled a cross this post. I had actually just updated my realtec LAN driver to a beta version from my mobo’s website (Asrock faitality z68 professional gen3 mobo) and thought that was the problem but after downgrading the driver still no dice. After several hours of searching, like I said I stumble a cross this post and it was my exact problem (was even getting deep sleep error when the driver installation tried to detect the controller) I did have to leave my ram out for a bit longer (about 10 min) and I also took out the motherboard battery and unplugged the PC and pressed the power button a few times to discharge any extra current. I new my mobo reset because during post I had to reset system time and date but as soon as I logged into windows I had my connection back!! I immediately set the controller to not be shut off so hopefully it won’t happen again. Thanks for the extremely helpful post and also the helpful comments!!
Apr 09, 2012 @ 15:06:53
Taking out the RAM and worked perfectly!
Apr 12, 2012 @ 04:14:31
Hey so I did all your tips. It was great. The issue is I only get a temporary solution. So sometimes when I put my computer to sleep or shut it down and turn it back on this deep sleep issue tends to still be there. I did uncheck the allow the computer to turn off the device in device manager. I hope somebody can help. I always have to turn off the computer. Take out my laptop battery and then let it sit for 10-15 minutes and then put the battery back in and start the computer up again to have the driver appear again. I hope somebody can help me =]

Taking out the battery solved the problem on Gigabyte M1405
Thanks to all %%-
Apr 13, 2012 @ 11:27:46
I removed my ram chips and leave them out for about 10 minutes and then put them back in and when i tried to start the computer, The computer wont boot , no beeps its just black screen. The ram chips are placed properly, I tried removing it and then putting it back in but nothing happens. I dont know what is the problem. Please Help!!.
Apr 13, 2012 @ 20:56:14
What I did was similar to those above since I have a laptop and messing with RAM and my mobo wasn’t really ideal.
1 – Install the driver
2 – Shutdown my computer
3 – Take out the battery for ~20 minutes
4 – Press the power button a few times
5 – Put the battery back in along with the ethernet cable
6 – Boot up
Apr 14, 2012 @ 01:22:00
WOW! Thanks! For once something actually works! My LAN card wasn’t working so I reformatted my entire computer and it still wasn’t working. So then I read this website and I just turned the power off and booted up without the RAM, pressed the power button a few times as it wasn’t able to boot up without any RAM. Than I just flipped the switch back to off because it kept trying to reboot, Put the RAM back in and it found the LAN connection! Oh well I always have that extra LAN card for back up but I also turned off the sleep mode so maybe this won’t happen again.
Apr 16, 2012 @ 16:19:55
Hi Adeel Ejaz
I did what you had written , i tried all possible methods, unplugged all cables from mother(M4A89TD PRO USB3) and kept that way for 24 hours , but the result was same , Windows(7) could not find the Network Adapter…I got frustrated and got a new Ethernet card(Dlink 520TX) and worked like a charm…I guess u were extremely lucky to get back your adapter ..
Anyways thanks …..
Apr 16, 2012 @ 16:44:01
I’ve had a quite a few people post that they got it fixed by removing RAM for a few minutes. But again, each problem, although has the same error message, has it’s own reason. I’m pretty sure its a faulty driver issue that has been fixed with new versions, well in my case at least
Apr 18, 2012 @ 13:44:50
So are sure its not a hardware issue,I think my onboard network adapter got cooked..and Can it be fixed by an updated driver from realtek…If so i will surely give a try once again to wakeup my onboard adapter.
Thanks for reply.
Apr 19, 2012 @ 18:34:18
I do everything,take out,ram,graphic card.MB battery,reinstall windows,update BIOS,reset MB by reset button,clear CMOS and it still not working. I try to instal OSx on PC and when I launch Windows my network card disappear. My MB is AsRock PRO3 P67 with Realtek 8111E. please help D:
Apr 21, 2012 @ 03:19:03
The best possible way is to get a new PCI Ethernet card(dlink) and get your network adapter back. I guess Realtek won’t get up from deep sleep,
Apr 21, 2012 @ 21:12:55
now i have connect by wifi edimax ED16160,i leave computer without ram(RAM and Graphic Card) for 30h,and nothing happend. I’ve got current warranty for MB. Is any way to wake my realtek?
Apr 23, 2012 @ 12:44:10
If you have warranty on your MB you can go to there service center and get it repaired. It wont wakeup .. either u buy a new ethernet card or get it repaired.
May 08, 2012 @ 08:43:17
thanks Mr.adeelejaz i used external hard disk at start-up and the network care got activated..it was not working
May 09, 2012 @ 13:52:21
Man, you just have saved me! Removing RAM and Battery really worked and I hardly can believe it. Well done!
Many THANKS!
Tom

Additional Comment: After fixing the problem, I was wondering why all Security Certificates in the Browser have been outdated. No wonder, when System Time is resetted to 1.1.2007 after Battery removal…
;O)

Hello there, You have done a great job. I will certainly digg it and for my part recommend to my friends. I am sure they’ll be benefited from this website.
