LAN Port stopped working suddenly

[Chicken Patty]

Hello everyone,

I came home yesterday to find that my PC in my specs had no Internet connection. I narrowed it down to be the PC itself and not any cables/modem/router etc. Now I went ahead and tried uninstalling and installing the LAN drivers again but it doesn't detect a LAN port.

At this point it gives me an error message and states that the Realtek Ethernet Controller could be in "Deep Sleep Mode". To connect the cable to get it going. However cable is connected and verified to work.

I've googled intensively and have tried many suggestions such as certain command prompts, registry edits, special permissions, and different methods of installing the drivers.

Is my LAN Port dead, or something else might be the issue? Please note we did have a power outage yesterday as my other PC had also restarted like the one with the problem did. The second PC is perfectly fine though. Any other suggestions and/or advice? Thanks in advance.

I had the same problem with an Asus lga775 board, I ended up installing a PCI nic. Sorry, not much help.

 

[DRDNA]

Did you try a restore point just for kicks?

 

[Jstn7477]

Had the same thing happen to the crappy Realtek 10/100 NIC on a $40 Biostar board after a power outage a few months back. Couldn't get it working so I disabled it and threw in an old PCI one and no problems since. My other computers on the same circuit were unaffected.

 

[Chicken Patty]

I haven't tried a restore point yet, but I definitely could. If not looks like a PCI NIC is my best bet.

id recommend disabling auto power up after power is cut option in bios.

 

[Chicken Patty]

I did that to not lose crunching time. What would be the advantage of doing so?

its caused issues with hw before for me

 

[CounterZeus]

it's a long shot, but maybe too high cpu overclock?

Shitty deal David. The pci-e option is cheap and more then likley fix the problem.

When it goes it just goes. If you never changed any setting then I think you know the answer.

Was just curious, thanks for sharing.

CPU was running at default clocks.

Yeah think I'm going to go grab a PCI NIC card after work today and call it a day. Oh well.

Doesn't seem likely that this will help you at all, but I had an old board that did that. I disabled the NIC in the device manager and then reenabled it. Whatever happened with that it fixed it.

 

[Chicken Patty]

Tried that, still nothing.

There are a few things that might work, if, the port did not die.

However, try turning off the power, un-plugging the PSU from the wall, remove the CMOS battery, and press the start switch (hold for 10+ seconds).
Get your favorite beverage and imbibe.
After, you have done this, re-install CMOS battery, plug in PSU, and turn on.
Boot up.

This is to drain the system, not necessarily to reset the bios; but, to drain any available power going to the embedded memory on the RTL8111E.
And, for this to be done... all power to that chip needs to be drained... including any auxiliary power (battery backup, standby from PSU, even the caps.).
Hopefully, it is corrupt or frozen register bits on the eeprom and they will clear or fall back to default.

EDIT: And, what color are the LAN lights on the port showing?

 

[Chicken Patty]

No lights. I just bought a PCI NIC and I get the same error while installing its drivers than the onboard. I made sure the onboard was disabled as well. Now what?

 

[95Viper]

1. You might wanna be sure your Firewall is not blocking the access to the lan(nics).

2. Try, if you have not yet, unplug the cable to the Nic or nics.
Go into windows, open control panel, find the nic and un-install the nic (check the box to un-install any driver/software, too). You may have to click the option to show hidden hardware in the menu.
Then, goto programs and features in the control panel and un-install any realtek and/or other software for your lan cards.

Restart the computer after you have completed this.
Hopefully this will force windows to try and load it's drivers.

Edit: Personally, I am not fond of System restore, but did you ever try that option?

power the system down remote all power from the system (psu,cmos battery ect ect)make sure you hold the power button down for 15 seconds to discharge the caps)
then take a small flat head and stick it in the Ethernet port
short pins 5 and 6 for 15 seconds
that should do it
I need todo this on my machine at least once a year

Had to be an Intel board? lol

I have issues when my modem goes ofline cuz of the ISP doing upgrads and such or after a black out... I must remove the lan driver or I cant get online for about 5min hahahah

What did this fix? How?

 

[OneMoar]

not sure what it does but it works I discovered it by accident

 

[Radical_Edward]

Are you sure it's not Modem/cable/ or router?

We have seen plenty of people loose equipment like that during power outages. (I work for a ISP.)

 

[Chicken Patty]

Well guys, I went ahead and just installed W8, it's good now, using the NIC card though, didn't even try using the onboard.

Anyhow, now my issue is sound. I've installed the drivers off the ASUS website, and it installed correctly, asked me to reboot which I did. However, Windows still says audio device is disabled. Any ideas?

...and yes, it's enabled in the BIOS and drivers are the Windows 8 64 bit drivers as well.

I'm guessing it is sorta what my post 14 had to do with.

Quote Realtek RTL8111E web page:

To support WOL from a deep power down state (e.g., D3cold, i.e., main power is off and only auxiliary exists), the auxiliary power source must be able to provide the needed power for the RTL8111E.

At OP:
Straw grasping time...
Do you have the "Accusys Inc – Storage- ACS-6xxxx” driver for your storage controller in your device manager or added by a windows update?
If so, remove it totally.

Here is how and this instrutions from an ASRock site, however I have found post about it happening to ASUS, ASUStek, and Gigabyte p67, p68 and even x58 boards for some odd reasons -->http://www.asrock.com/support/faq.asp?id=277

Like I said, a shot in the dark here.

Edit: Darn you. You posted will I was still typing... I type slow.

No I don't.

Meant on old install, oh well... old news now.

What speaker setup?
Is the realtek speakers set as default and enabled in your WINDOWS playback devices?


Why is the front (orange) and green (rear) jacks both highlighted in the pic you posted of the Realtek control panel? At least it looks that way.
