Realtek Ethernet Controller Driver Deep Sleep Mode

(5) Was updating the RelTek driver and got the message: Realtek Network Controller Not found. If deep sleep mode please plug the cable. Feb 12, 2013 - When I try to re-install the driver this is the error I get: 'The Realtek Network Controller was not found. If deep sleep mode is enabled please. However, there’s nothing to worry about because this is only a sign that you Realtek's network controller deep sleep mode issue. This Realtek Ethernet Controller Driver Lenovo often takes place if there is lack of a needed file when you run a certain program in your personal computer. Unless it is not a system file, acquiring another copy. 2)Turned laptop back on after reassembly.STILL can not detect an ethernet controller. Getting same message 'The RealTek Network Adapter/Controller was not found. If Deep Sleep Mode enabled Please Plug the Cable' Iwent pretty far with this it seems. I dont think anyone else has reportedly gone any further.

The realtek Network Controller was not found. If deep sleep mode is enabled Please plug the cable.

Last night we had a huge unexpected thunderstom, and the power went off for a few seconds at one point. My computer must have gotten messed up during this because in the morning my wired ethernet connection was no longer working.

I tried to reinstall the drivers but I keep getting the following error message, 'The realtek Network Controller was not found. If deep sleep mode is enabled Please plug the cable.'.

Many people online give instructions on how to disable the deep sleep mode by going into the Device Manager, but Ethernet is no longer listed anywhere in device manager. I did try resetting the CMOS battery, and I did try going into the BIOS and making sure that LAN was enabled.

I realize that I may just have to replace the network adapter but I want to explore all other options before it comes to that, so any and all help in this situation would be much appreciated.

THere is no netwok adapter for LAN in DEvice Manager, only a Ralink RT3290 802,11bgn wi-fi adapter, which works OK.

And so I cannot use a LAN connection, I can use wi-fi though. I've tried another LAN cable although I since found there is no LAN driver anyway.
Windows 10 Anniversary Build, latest (I think).
I tried installing the Lan drivers from the HP site but each time I got a message 'Realtek Network Controller was not found. If deep sleep mode is enabled please plug the cable'.
I can get LAN connection working OK on another laptop from the same router. I don't know what the driver is even so I'm not sure how I can download it but how do I get the Controller recognised again?
I don't know what that means but how do I get this sorted please?

Hi:

The only suggestion I can offer would be to try this...

1. Install the AMD Chipset drivers from the link below, and restart the PC.

You want the 1st file listed on the webpage.

2. Then install the latest Realtek ethernet driver from the link below and restart the PC.

Download, unzip and run the setup application for the operating system your notebook is running.

If that doesn't work, you can pretty much bet that the ethernet chip on the motherboard has failed.

Hi, I will try that shortly but I'm puzzled by the references to RAID in the text, I don't use it nor do I want it. Can I be sure that is the correct driver set please?

Thank you.

Your notebook's drive controller is not set to RAID.

The chipset driver will only install the drivers applicable to the motherboard your PC has.

Well, I downloaded the Amd chipset driver from the first link but it failed to install due to this error :

Error 174 – AMD Installer Cannot Continue Due to an Unsupported AMD Graphics Hardware Configuration. OK, got past that but when I tried ti install the last item on your list I got the same result as when I started. I mean that I had already tried toi i nstal the LAN driver and got the message about 'Realtek Network Controller could not be found. If deep sleep mode is enabled please plug the cable'.

So from what you say the controller has failed, but what does that mean now, is it a repairable item or does it mean a new laptop? This one is only just over 2 years old.

I have seen some reference to this message : http://www.tomshardware.co.uk/answers/id-2602481/realtek-network-controller-found-deep-sleep-mode.ht...

Realtek Ethernet Controller Drivers Windows 7

So I looked in BIOS and saw a '!'next to Network adadpter which doesn't look good. And there is stuff about power supllies too. Have you come across this at all?

Thank you for your help!

You're very welcome.

That is probably a bad sign if you see a ! mark in the BIOS next to the ethernet adapter.

You would have to replace the entire motherboard to fix the problem, so the easiest thing to do IMO, is to purchase an external USB to RJ-45 10/100/1000 gigabit ethernet adapter if you don't want to buy a new notebook.

Shouldn't cost more than $20-$25.

Realtek Ethernet Controller Driver Deep Sleep Mode

OK Paul, panic over!

This business about the controller not being found, I discovered this:

The controller goes into sleep mode and the way to wake it up is to remove the laptop battery for about 10 minutes. I did this and I now have my LAN back again! Which is a Realtek PCIe GBE Family Controller.

So I'm a happy bunny again and I've learned something else.

My thanks for your assistance.
