Realtek Network Controller was not found -- Deep Sleep Mode

[aandyaoe]

So I recently built my own computer. Everything was working fine, I was able to make everything work fine. Then yesterday morning I started up my computer and it was not connected to the internet. My ethernet was plugged in and everything was as it should be. I went in to device manager and noticed that my realtek network controller was not in the device list under network adapters. I then tried to reinstall my LAN drivers from ASUS (my motherboard) which is how I got it to work in the first place. However, this time when it "finishes" installing an error pops up and says "The realtek Network Controller was not found. If deep sleep mode is enabled Please plug the cable."

I went on to many forums and here is what I've tried so far...

Unplugged Power supply and flipped the power supply switch to off and let it sit for 10 mins (also I let it sit for a few hours and same result)

Took out the RAM and did the above step again

Went into Bios and made sure that my LAN settings were all enabled (also tried resetting all my settings to the default)

Also flashing the bios (I'm not sure if I did this correctly, let me know what I should do, or how I can tell if I did this correctly)

I'm at a loss..... I have been working on this now for several hours and still have not come up with a solution. If anyone can help me with this, it would be much appreciated.

Thanks.

Hello, i had the same problem but i fix it, it´s very very easy, so... I installed the Realtek Network Driver and it said the same thing, Realtek driver was not found, please plug in the cable, i tried many times and nothing so i start to think and i realize that some computers can´t support some drivers, so i uninstall the realtek driver and i installed the atheros driver, after installed i reboot the laptop and Voilá, good as new, so if you installed realtek driver uninstall it and install atheros if neither of those work send me a message there is another way to fix the problem.
Regards

Oh. My. God. Thank you so much!
I tried everything to get my LAN working and this did it for me!
Thanks a lot!

After trying all the suggestions on multiple sites, without solution. I installed a DLINK Wireless adapter and connected it to wifi. then right-clicked on computer, Manage - Device Manager- Other devices and right clicked, Ethernet Controller and selected Update Driver ( It dowloaded Atheros AR8152/8158 PCI-E Fast Ethernet Controller (NDIS 6.20). and that solved it.

Thanks

I got all working by
1. Set all LAN settings disabled from bios
2. Uninstall network adapter device and drivers from Device manager
3. Reboot and enable all LAN settings and when i logged in, drivers was started install automatically
And that's how i solved it.

So, you turn on your PC and the network controller is not even listed in the device manager? Here’s the solution.

1. Turn off the PC, unplug the power cable!
2. Do a power dance for 10 minutes and finish it with a backflip! (No, I’m just kidding, simply wait for some time)
3. Turn on the PC and you’ll see that the network controller is working again. It’s magic!
4. IMPORTANT: To avoid this problem in the future, make sure to disallow the computer to turn off devices

The reason why this works is that some information are stored in your motherboard battery even after shutting down the computer. Also, to reset the network controller you need to unplug the power or it will remember the “device status”. It gets a lot more technical and there are more reasons why this works, but let’s keep this simple.

thanks it is working....

Thanks dude BEST SOLUTION EVER!!!...
Go to this location and find LAN something... is [disabled] and change obviously for [ENABLED]
then if u need for reinstall the lan driver just do it.

Just boot in safe mode with network with your lan in the pc and it will install the driver after that turn of your pc and turn it on. Done

After trying the dozens of possible approaches offer here and on other sites (pull RAM and dance for a half hour, etc.) with no luck at all, I finally hit on a solution that was OFFS obvious: update the network driver. In my case, it was an Intel I217-V Driver (53 meg) which I did through the Linux Mint side of my dual-boot machine. (On the Linux side, there never was a problem with network access). Installed it, rebooted, fired up my browser, and found myself looking at today's headlines on my home page. Since this is my wife's new computer for her work (a Lenovo Think Server T-140) and everything else about the system worked just fine, I'm delighted that I found an approach that worked!

I had the same problem as the publisher I installed all four Realtek drivers turned off system don the dance turned it back on still nothing until . I went to
Step 1 control panel
2 system and secuirty
3 device manager in system
4 other devices
5 Ethernet lan the first one in the list enter
6 click driver in the top of the box next to general hit the update driver button and ok and walla sorted . Sorry 5 and 6 ain't that accurate with wording since I've done it I can't back pedal good luck it seems that it installs correctly but gets cock blocked until u go through the back door thanks for all the answers they did lead me to this point so friendly happy now

i had the same problem with a Lenovo M72Z, all i did was install older drivers from as far back as 2012 and it fixed the issue, the new driver had an issue for me with deep sleep.

 

[Riju123]

I had the same problem. Just go to the device manager --> network adapter -->ethernet controller or lan driver --> properties --> details --> device description --> hardware id. Identify the hardware id and download the driver from internet. Notice that some PC's have ethernet drivers different from realtek such as broadcom,atheros e.t.c. You can download the driver easily using a hardware id.

This totally worked for me. Thank you!!!

This is how I resolved this problem without having to use a screwdriver or look inside my laptop (HP Envy m6 with Realtek Ethernet LAN Adapter running Windows 7 Ultimate x64).

STEP1: Find and install the original Realtek drivers.

Download the original Realtek drivers here:

http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=4&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#91

Another way to find the drivers:
Go to http://www.realtek.com.tw/downloads/
Download Search RTL8110SC
Click on RTL8110SC(L) (Software)
Select your Operating System (i.e. Windows)
Locate your version under descripton and then click US1 under Site1 to download

Right click the Ethernet Adapter in the Device Manager
Click Update Driver software
Select Browser my computer for driver software
Select the folder where the drivers are extracted and then click Ok
This should install the correct drivers for you


STEP2: Prevent the Ethernet adapter from deep sleep.

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”

I hope this helps.

or buy a lan card

 

[nasshan79]

I reinstalled the driver with my laptop connected to my router. Realtek driver showed up immediately was able to connect to network no problem. I then changed my settings to not allow my computer to turn off my network card. No problems since.

for the constant struggle of finding the answer on the net for about a whole day, this site, the top answer that google had gave me, surely is misleading and a disappointment. More on about the subsequent sites that comes after this. This whole charade is futile.

this will gave you a direct approach of facing your current predicament

If the link above managed to perish, do leave me a message and hopefully I'm able to see it

went to BIOS (F2). go to advanced, system configuration, then enable the Built-in LAN. I tried everything that's in this forum, then I went and checked. It was in disabled. Who knows why. After I enabled it, it worked like a charm.

Thanks a million for this!, solved my problem

 

[NatalieEGH]

I corrected the problem by:

1. booting into BIOS
2. finding where the LAN connection was defined to exist (on my BIOS you lock or unlock in BIOS instead of enable/disable).
3. locking the device in BIOS
4. booting to Windows
5. booting into BIOS
6. unlocking the device
7. booting into Windows.


This is a lot faster than waiting for the CMOS battery to drain and on my system to get to the battery to remove it would be a royal pain. I would have added the other 4GB memory if it was not a ton of work to get to the motherboard. My eyes are not good enough, my fingers small enough, nor hand steady enough to be working with those tiny wires and connections. I suspect many of you are in the same boat if you must disassemble your laptop.
