Realtek’s network controller deep sleep mode issue

flattr this!

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.

Note 4: Some people have reported that “Loading Default Settings” in the BIOS solves the issue as well. You will need to go into the BIOS at start up by pressing the Delete key (can be F2 or some other, please check the message at the start of the screen). Once in BIOS, you can press F10 to “Load Default Settings” (If you don’t see that, look for a button saying that. It is usually around the “Save & Exit” Button). Once loaded, hit “Save & Exit”. This will restart your computer and some people have reported this fixes the issue.

Once you have it working, to make sure the network controller doesn’t go into sleep mode again, try this:

  1. Open Device Manager by:
    1. Go to Start
    2. Click Control Panel
    3. Choose System and Security
    4. Click Device Manager (under System)
  2. Open Network Controller properties by:
    1. Double-click Network adapters to expand it
    2. Double-click the Realtek Network Controller
  3. Turn off Deep Sleep mode by:
    1. Choose the Power Management tab
    2. 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!

  • David….

    This same thing is happen to me right now….. lol….. Tryed all the above…It did came on for a few minutes and then cut back off, when i restart my PC……. Pleaseee helppppp :)

  • Emil

    Worked for me! Thanks for the fix!

  • ts

    None of your instructions have helped

  • Manu

    I have a HP DV-6 series laptop. Same issue of “deep sleep” from Realtek NIC card. Issue resolved from BIOS settings.

    Power saving mode disabled.

  • James

    Wow, glad I found this! Suddenly, for seemingly no reason, my network adapter completely disappeared after a routine wake from sleep. I tried uninstalling updates, reinstalling drivers, restoring to previous backup points, shutting down and restarting, even unplugging the power cord and reattaching – nothing worked.

    What DID work was disconnecting the power cord and **hitting the boot button multiple times** (desktop), then plugging the power and network back in, and booting.

    This is what worked for me to wake it up. Thanks all who contributed!

  • steffan

    I had the same problem.
    Before trying with the memory I tried other solution that it worked: I have a switcher on/off at the power supply and after I had shut down the PC I turned off the power supply; I waited about 2 minutes then I turned on again the power supply and when I booted the PC the problem was solved!
    I suppose it would worked with the memory anyway.

  • Soumya

  • Carlos

    I have Win7 64Bit PC.
    The following: GIGABYTE GA-A75M-S2V

    I cannot connect to the internet.
    1. I installed the Atheros driver that is on the motherboard installation cd – no success
    Message: Installer can’t find Atheros AR81 family ethernet controller on your system.

    2. Searched for driver on unofficial Atheros web site: installled it and now the green light is on but message is: The Realtek Network Controller was not found. If in Deep Sleep mode Please plug in the cable.

    3. I tool the ram out for 10 minutes or so and then set them back in to no avail.
    4. Network adapter is not even listed under Device Manager
    5. Now the green light is not on again.

    Any ideas ?

  • Carlos

    In reference to my previous comment: the way the LAN is enabled on the BIOS.

  • Mr Koolaid

    I too have the same issue as Carlos and Somouya. I have an ASUS P7H55-M Pro motherboard. Ive downloaded the chipset and LAN drivers and I still cant get my PC to recognize the ethernet connection or connect to the internet. Can someone help?

  • kumar

    sir, even i am having the same problem with network adapter
    my mother board was replaced once, will that cause any problem to network adapters
    i tried every thing you mentioned above but still the problem persists
    i dont even see reltek network driver listed in device manager

    please help me out as i cannot format the system for this issue

    • http://adeelejaz.com/ Adeel Ejaz

      The network controller is on the motherboard, so yea, replacing that can affect. Please read all the comments as different suggestions have been made to solve this. If nothing works, you will need to change your motherboard.

  • Kiwi T

    Hey
    I have a Toshiba L500 Laptop which I reinstalled windows 7 on using its own cds. After the reinstall I found that I had wireless working fine however no wired connection :(
    I checked that I had a live connection (cable working fine) and that the lights on the ethernet port were working. However in the device manager there was no realtek lan controller. I downloaded the correct drivers from toshiba and realtek for 64 bit and installed yet at the end I got the dreaded message “The RealTek Network Adapter/Controller was not found. If Deep Sleep Mode enabled Please Plug the Cable”
    Gave the take out battery suggestion a go but no luck. Decided to try and go into bios menu by pushing F2 on boot, went to system configuration and disabled the lan card. I saved changes and rebooted pushed F2 straight away and enabled lan. logged into windows and the wired connection was working. I went in and turned off the sleep setting however this did not work as the next time I shut down I was back to no lan card installed message. So I disabled and enabled again to get it to show up in device manager again and this time played with the updates and downgrades which seemed to change all the settings in the network adapter menu! Fingers crossed it stays working :/

  • rannigan

    I have a question, does your computer have to be on or off when you remove your RAM? ( probably a stupid question, but I have my doubts so I’m asking it anyway )

    • http://adeelejaz.com/ Adeel Ejaz

      Computer should be off and the power cord taken out out of the socket. You should also touch some metal part of your case before touching any component to remove static charge off your hands.

    • http://www.facebook.com/sanjoyp7er Sanjoy Podder

      no need to do all the fucking thing. just boot ur pc or laptop from lan. all will be done. enjoy.

      • http://www.facebook.com/jcrivello Jonathan Crivello

        or reset & load defaults on exit from BIOS

      • http://pulse.yahoo.com/_YZA4XFLJRC36EMBX5Q34762Y74 Alex

        First of all, there’s no need to swear. Second, people with one computer will have a somewhat difficult time booting from LAN. Thank you for your contribution.

  • Wtffff

    i did all the above, and nothing works, i guess its time to buy a new pci. mine its onboard, i got a p8p67.m pro… expensive and a shame to see this hapenning to it…

  • Soumya

    Ok i have the same problem too mine is also Realtek

    i have a solution but seems to me the LAN cards are damaged somehow ..

    1. Shut Down PC
    2. Remove power Plugs and Lan Cable
    3. Try rubbing the Lan Port with your finger for 30 seconds [ Put ur fingers inside and rub hard ]
    4. Plug and start PC
    5. I am doing this almost every-time I shut my Computer for long hours [ 6hrs ]
    6. To avoid this issue you can keep your PC on generally I shut down my PC for 5-10 minutes a day and keep it on rest of the time to avoid the issue

  • Double_A

    I solved this problem like this:
    – Disable Intel SpeedStep (if any) in BIOS

    After I did that Windows just installed the driver when I booted the next time.

  • Rajasri

    I recently formatted my pc. win vista home basic 32 bit. I installed network adapter softwares that came with my motherboard cd. The problem is that ” some driver or hardware issues in the Realtek so n so.. ” I tried reinstalling the drivers again..but it dint work.got this deep sleep mode error. When i tried ur procedure ,i couldn’t see the power options tab when i double click the realtek controller under network adapter. What can i do now ?

  • petru dolca

    driver its not good download other driver http://www.realteck.com

    I just want to post that Note 2 worked on the Toshiba NB305-N600 netbook. I removed the RAM and waited 10 minutes, reinstalled the RAM, and reinstalled the driver from the Toshiba support website.

  • ArunKNambiar

    I had the same problem, Its solved,. I just removed the power cable and then battery. Then pressed the power botton to release all static power in laptop. Then again i put the battery alone not power. then switched on. It worked   fine.
    dont forget to do this also

    FOR THE MANY HAVING THIS ISSUE: *******************************************Update NOV 2012- KNOWN FIX FOR ISSUE

    I just had this issue with a DELL INSP n4110- Win 7 home 64 bit- Asus MB, 6gb RAM, 650 GB  hd. Phoenix-tianos build BIOS.SPENT 3 DAYS KNOWING THIS WAS NOT A HARDWARE FAILURE…DO NOT BUY A NEW MB OR NIC CARD UNTIL YOU HAVE TRIED ALL THE STEPS MENTIONED ABOVE OR HAVE A PROFESSIONAL DO IT FOR YOU..DONT GET STIFFED EITHER..IT MOST LIKELY IS (in some cases) JUST A BIOS ISSUE…

    Ok so if you have
    * taken out the battery (cmos too if you have one.)
    *you have taken out the RAM for an hour (or more) *.
    *have reformatted your system
    *tried “flashing ” the BIOS
    *unistalling/reinstalling adptrs
    *diagnosed ram
    *check power state settings
    *updated drivers thru dev mgr
    and you still are unable to get the system to detect a network adptr AND you recieve a message “if your pc is in deep sleep, please plug the cable in”…..

     I did notice how my computer got into deep sleep mode. I made a BIOS  settings change by disabling an HD Password that was set by my newphew. Upon exit…i must have hit “load set up defaults” thats when i discovered the loss of my nic components and was unable to find a netwrok adptr. i also got the
    “your computer is in deep sleep mode..please plug in the cable ….”   I KNEW THIS WAS  NOT A HARDWARE ISSUE…I TOOK THIS COMPUTER APART SEVERAL TIMES.  i ran MEM-TEST to check for RAM errors, I ran HD Tune-pro to see if i had issues with the HD. i  clean installed windows multiple times and also flashed my BIOS. I knew all the more AFTER I DID BUY A NEW NIC CARD ..it still wasnt found ….
     TRY THIS*****

    Go into your BIOS   (to those that dont know turn on pc/or restart and immendiatley key “f2″ go to adavnced/. ( every build is diff…try to use similar paths)
    go to each tab and hit “load defualts”
    then when you go to exit the bios…MAKE SURE YOU HIT “Load set up defualts” (if it says that or whatever” regardless of its settings” go back into windows (let pc restart)……see if a baloon at bottom right hand portion of your screen says “loading/installing/found new hardware” if you see this…we solved your issue.
     
    now if that did nt do it….ONCE MORE…go back into the BIOS…find where the settings for either “intergrated nic” or “on-board LAN” ENSURE THEY ARE “ENABLED”. That should do it …EXIT AND SAVE CHANGES…LET pc reboot…it should have worked. that is all the info i can offer. hope it helps.

    I built this computer almost 5 years ago and have never had a problem with the network adapter running under Vista or Ubuntu. Only since I installed Windows 7 have I had a problem. 

    Fortunately, I’m always able to bring the network adapter back by shutting down and unplugging the power cord for a couple of minutes; no RAM or battery removal required. Unfortunately, changing the power management setting does not resolve the issue, and the network adapter disappears every single time I shut down the computer. 

    Here’s what I have to do:

    1. Start the computer — see that network adapter is missing from Device Manager.

    2. Shut down the computer, disconnect the power cable for a couple of minutes.

    3. Boot. Network adapter is back in Device Manager. It say’s it’s operating normally, but it isn’t. When I try to enable it, it then says it can’t be started (Code 10).

    4. Uninstall network adapter.

    5. Shut down. Unplug power cord for a couple of minutes.

    6. Restart. System reinstalls network adapter. 

    Most of the time this gets me back on the network. Sometimes I have to boot once more.This happens every single time I power down the computer.

    I’ve installed the latest driver from Biostar. I’ve fussed with the driver settings. I’ve checked the BIOS settings. I have not flashed my BIOS. The fact that it’s fine in everything but Win 7 makes me feel like it’s not a BIOS issue.

  • Lou Butler

    I downloaded and installed a legitimate Win 7 .iso from Digital River that must have been corrupted because it didn’t install the Realtek Ethernet driver and I ended up with this “Deep Sleep” message when I tried to manually install the driver.

    I googled to this site and then tried all the hardware tricks listed here and nothing worked.

    After that, I bought the Win 8 upgrade and installed it and all the drivers were there and everything worked fine.

    After that, I reinstalled the Win 7 .iso on a separate partition, and again, there was no Realtek driver installed in Win 7.

    So, in my case, I’m now sure that my missing Realtek Ethernet driver was a software problem and not a hardware problem.

    I had this issue then removed ram and pc worked for awhile, now it’s back sometimes when pc goes into stand by/ sleep when i start up again network doesn’t ork i have to remove network cable restart and run network trubbleshooter and then plug cable back in again..

    I have bough a new motherboard since i thought this was my MB making the problem.. feel kinda silly now and maybe i send it back instead..

  • dottronik

    Hey guys, I have a Dell Studio XPS 435 machine. A lightning and thunderstorm in my residential area had knocked the power out. I am very careful about leaving my machine on during the rain or thunderstorms. I received this message when I followed the step by step instruction wizard to install network/ethernet driver. This popped up:

    The RealTek Network Adapter/Controller was not found. If Deep Sleep Mode enabled Please Plug the Cable

    I followed these steps:
    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!

    Awesome, up and running, everything is good to go. Online just fine.

    Next Open Device Manager by:

    Go to StartClick Control PanelChoose System and SecurityClick Device Manager (under System)

    Open Network Controller properties by:
    Double-click Network adapters to expand itDouble-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!

    Thank you, saved me some dollars as my next option was to replace a network adapter card.

  • sumanth

    Here I have solved it guys..

    I have A Realtek adapter and run Win 8.1 on my Dell desktop. My WOL worked about once and then stopped. What seemed to happen is that the network card would stay powered on in sleep mode but would lose its connection to the router upon sleep. After doing all of the above (BIOS settings and power mgmt settings) I found that THIS WORKED:
    1) Go to settings for realtek network adapter in Device Manager 2) Go to Advanced Tab 3) Go to “WOL & Shutdown Link Speed” and set to “Not Speed Down”. This seems to prevent the network card from losing the lease with my router when computer enters sleep. (You can check this by looking at the cards yellow LED blinker or my checking your router for connected devices).
