Ethernet Controller not working

Q: Ethernet Controller not working

Clean Install of Win XP Pro sp2 and the ethernet controller is not working. It does not show up in the device manager with the usual yellow question marks, the ethernet controller does not show up at all. The ethernet controller is a Realtek RTL8100C. The computer is a Compaq SR2150NX that shipped originally with Vista (way to slow), I switched it to XP (very fast). Mom Brd is a ECS RC415ST-HM (HP/Compaq Mom Brd name: Alhena5-GL6). I found all of the XP drivers for the Mom Brd (including the ethernet controller) and everything works fine except the ethernet controller. The onboard ethernet is enabled in the BIOS. Could the Realtek chip be bad? How do you force-feed it ethernet drivers when the controller doesn't show up in the device manager? Any advice sure would be appreciated. Thanks...

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Please help me! Today suddenly my internet stopped for no reason! When I open the device manager and click on other devices and click network my Ethernet controller has a little yellow (!)sign next to it and when I click properties it says no driver installed, please tell me what to do!

Thank you

Learn to use Google :-)

google for that code "VEN_1969&DEV_1083&SUBSYS_76801462"

You will find it is an Atheros device. These are supplied by Toshiba.

I'm assuming it's a wireless device due to the results that google supplies.

I'm certain you can find the correct driver in one of the google search results.

Good luck!

Ok as the title says I recently did a fresh reinstall of my copy of Vista Home Premium. Everything seems to be going reasonably well so far except that when I check my list of devices in Device Manager, my ethernet controller has a yellow exclamation mark next to it (actually there is an "unknown device" with the same thing as well but I will worry about that if it becomes a problem).

When I try to update the driver, Vista fails to find anything and informs me that it might not be compatible.....which cant be right as it was running fine before the reinstall.

Anyway after some searching online I discover that I can get the relevant driver from the relevant manufacturer. Who is the manufacturer of the ethernet card I ask myself. Buggered if I know is my reply (my computer was put together by someone else).

So I stumbled across this seemingly nifty piece of software called Sandra by a company called SiSoftware. With its devine help (it does seem pretty nice to use actually considering I know nothing about this stuff) I believe I have discovered that the manufacturer is Asus and the chipset number (is that the right term?) is P5LD2-SE. However Sandra also shows up something called "Coreco RT8129 Fast Ethernet Adapter". Hmmmm.

Would anyone have any divine words of wisdom (and perhaps some links) on how I might go about locating the relevant driver for this ethernet controller? I am fortunate to have access to a usb wireless adapter but its not mine... Read more

I am sort of having the same issue. All of a sudden my Ethernet controller driver stopped working since last week. Error #28 cables are unplugged which they are NOT. I am not able to download from the setup disks (why do they make it so complicated). My linksys 4200 works fine w Internet connection along with Voipo phone service. Both items are new for my Dell dimension 8400 (maybe it's dying). I've had connectivity issues with my printer along iPod and iPad synching / restoring issues which miraculously fixed themselves.

My laptop is from Toshiba, model L650 PSK1JA OK3017. Here's Toshiba's driver page for my device:

Support :: Toshiba :: Computers, Laptops/Notebooks, Tablets, Televisions, DVD and Blu-Ray Players, Camcorders, Storage, Accessories, and more

I recently purchased a blank hard drive along with a copy of Windows 7 Ultimate 64 bit. I've installed all drivers listed on the page for a 64 bit system but when I try to install the "Intel Wireless LAN Driver (For Intel Model Only)" driver or Proset driver, the driver extraction begins, ends, but when the setup is meant to run, nothing happens. I've redownloaded it and attempted to install it twice to no avail.

Basically, I cannot connect to the internet and Windows cannot detect my network adapter.

If anyone can help me figure out what I need to install to get my network adapters to install, that'd be great. I can't call Toshiba support because their operating hours are when I'm at school.

Occasionally, when I try running the driver I mentioned before and the extraction is complete, when I select "No" as to whether I want to run the file, Windows gives me the error: "Archive Extractor -- Error occured in system module [-135]".

I still have my old, working hard drive, which I replaced because it was slow. Is it possible to grab the network drivers from that and transfer it to my new hard drive? I can use this hard drive to help you guys help me.

I have read/searched through most of the posts on this and various other sites and can't seem to find help with my problem. So hopefully someone will be able to help.

This morning when I woke up my computer worked properly. I then went to work, and when I turned it on I got the "blue screen of death." (I apologize for not posting the exact wording, but I did not think I would need it). I restarted the computer per the instructions, and it booted up. The computer, however, failed to connect to the wireless network. I noticed that the network icon was not in the taskbar. I then went to device manager and my integrated wireless adapter (Intel Pro/Wireless 2200BG) had a yellow triangle with an exclamation mark. I clicked on properties and under the 'general' tab the device status read:

This device cannot start (Code 10)
Click Troubleshoot to start the troubleshooter for this device

I then unistalled the controller and attempted to reinstall via the 'add hardware' program. I then received the message:

A problem occurred during hardware installation. Your device may not function properly

I then, believing it was a driver issue, downloaded the latest drivers from the intel website for my device on another computer. I uninstalled the controller again, and tried to install with the new drivers via a thumb drive. I received the same error message and the controller had the yellow triangle. When I clicked on properties this time I received the fol... Read more

A:Integrated Wireless Controller/PC Card Adapter/Ethernet port stopped working

Sounds like your motherboard is rapidly dying.

If the ethernet controller (or adapter) does not show under Network Adapters and is not in Other or Unknown devices with a warning or error message check in the BIOS (Setup) to see if it somehow got disabled. If it is already enabled, or doesn't show there, see my first paragraph.

When the ethernet controller is defective it can prevent other integrated and/or PCMCIA networking cards from working. When this happens sometimes a USB adapter will work.

Hello guys, I've been having a lot of issues with my AMD drivers, specially when it comes to chipset and video drivers. I recently had to downgrade my video drivers to June 2015 release date, that was the only solution found so I could run games properly (with recent drivers, games that should run with 100fps+ were running with 15fps)..

But that is not the point of this thread, instead, I'm here because after a few weeks running this drivers, I noticed my WiFi was not connecting to my router (wich is working, I can get access with other computers/cel phones). In my drivers list, the Ethernet controller and SM Bus controller are flagged as not installed.
I've tried to find these drivers, but AMD seems to only release packages of drivers. I've come to this download page:

where I should be getting the drivers that solve my problem, but the big issue is: apparently, by doing it, i will be reinstalling the latest video drivers (for the APU), and that is ABSOLUTELY NOT what i want.

Does anyone know how to solve this problem? And I mean: where can I get the sm bus and ethernet controller driver w/o having to install a bunch of unnecessary drivers?

My notebook is a MSI 60X 3BE
video card: Radeon HD 8970M
chipset: AMD A10-5750M (with Radeon HD 8650G)
motherboard: MSI MS-16FK

Thanks in advance.

Edit: I've downloaded the drivers in the link, installed and SM Bus is running properly, but Ethernet doesn't. Any further help?

I have a question (obviously), I recently redid my computer and may i say that everything is running wonderfully. There is only ONE problem that I cannot seem to eliminate no matter how much time or effort I put into it.

3 drivers, SM Bus Controller, Ethernet Controller and Coprocessor refuse to work properly. Every time I install the drivers I need for them and restart my computer I get a message from windows saying that it could not start properly, it gives me two options (well technically 5) load last working settings or start windows normally. Start windows normally restarts my computer taking me back to the exact same screen, selecting load last working settings lets windows boot but the 3 drivers appear in new hardware found again. I have tried at least 10 different sets of drivers for both the onboard graphics card (i know i need to order the PCIe card im getting still) as well as just the motherboard itself. I have installed all the drivers from the CD given w/ the motherboard and all work except these three. I tried multiple ones from the internet to no avail.

My specs are:
ASUS M3N72-D motherboard, chipset nVidia 750a SLI
Windows XP Pro, 32-bit
AMD Phenom 9600 Quadcore processor

I think that is all thats important, but if you need more just ask me, ill be checking this thread every few minutes.

A:SM Bus Controller, Ethernet Controller, and Coprocessor Problems

Sorry couldn't figure out how to edit to avoid double posting*

I have solved 2 of the 3 issues after spending about 10 hours of my day on them. I have fixed both the Coprocessor as well as the Ethernet Controller issue. Turns out they were just being rolled back with the load last working settings along with the SM Bus Controller which was the only one really having a problem. Still though, after uninstalling reinstalling disabling and so on and so forth, the SM Bus Controller continues to be a thorn in my side. I have disabled it to get rid of the annoying pop up every time the computer restarts (I figured this is ok b/c according to the device manager the device is inactive anyway so why not?).

Assuming you are using the ethernet port on the motherboard (not a separate card) you need to get the manufacturer and model number from the mb itself and go to their site to get the drivers for that and the SM bus controller. You don't mention the brand/model of the mb in your post - Micro ATX is a size specification, not mfr.

I am at my wits end!

I have an eMachines - E625 series laptop, and it used to have an INTERNAL Atheros wireless adaptor, and my LAN used to show up in my Network and Sharing. I would use this via ethernet to watch HDTV videos through my XBOX 360.

Then one fine day, my wireless stopped working. After multiple reformats, and purchasing an EXTERNAL dlink wireless network adapter, both my Atheros and LAN drivers have just completely dissappeared.

I have tried everything in the book!

I've gone to the eMachines website, and downloaded the drivers. The LAN driver says it installs fine, but WHOOPTY TAH, it's not there. I've checked in my device manager, under network adaptors. The only thing there is my external network adaptor. It's like they just died completely or something. Been whiped out of existence.

I can't connect to my xbox through ethernet (thank goodness I have a wireless adapter on my xbox too), and I would really like to start watching my hdtv videos again.

Before I take this messed up baby of a laptop to a professional, I thought I'd ask here.

If you need any information, just ask me. But please, HELP A GIRL OUT!

A:ethernet controller

With all those devices without the correct drivers it sounds to me that the system has just been reformatted and reloaded.

Since this is a custom system you will have to open the system and get the motherboard ID number which is printed on it somewhere.
We know it is a Biostar but we need to know exactly which motherboard.
Did a motherboard cd come with the system?

I assume that the network card is integrated as well.
If there are any devices that are not integrated into the motherboard please let us know.

What is a pci ethernet controller? Do I need that installed to use a dial-up modem, or is that just if you have a high-speed cable internet provider. If I need it for my dial-up, how do I install it?

A:pci ethernet controller

PCI Ethernet Controller is a network interface card used for cable/dsl modems, lans, etc. You don't need it for a dial up connection.

Alright I had a HP a520n(Listed below)that I used for about a year and today I decided I need to format it was getting really slow. So It all worked OK except this Ethernet Controller. I studyed up on it and found out this. It seems to be a NVIDIA MCP2 - Lan Controller.

Could you guys help me out with this one its the Computer that listed below.

Hp Pavillion a520n
Win XP Media Center Edition
Bios:Asus AMI(02/10/04)
Video Adapter nVidia GeForce MX Integrated GPU
160GB HD 7200RPM Ultra ATA/100
Samsung CD drive 48x
HP dvd writer 400c

A:Ethernet Controller


That link is to the "Complete collection of original network adapter device drivers" for your model from the HP a520n support.

Are you saying that yours is not there, or have you not downloaded all/any of the drivers from there?

Ill get right to it

After a recent format of a HP 525c desktop computer, i cannot access the internet due to missing drivers.
In the device manager i have two missing controllers:
1) ethernet
2) SM bus
which apear with a yellow '!' mark next to them.

I have visited the HP download center, and found nothing that can solve this (or at least it seems that way).

How can this be solved?
Thanks in advance

Hi and welcome. Did that machine come with an ethernet card installed or did you install it after the fact?

The website only mentions a modem driver.

Hello. I am new to this forum.

I just reformatted my computer and installed Windows XP home edition. I actually partitioned my HD in 3, leaving 8 GB for the XP. The XP is updated to service pack 2.
After installation, I did not have Internet connectivity. I updated many drivers using a second computer and a pen drive, but I do not know how to run a xps file.

Some features of my computer are:
Motherboard: Gigabyte GA-945GCM-S2C (with LAN)
Chipset: Intel Lakeport-G i945GC
Realtek RTL8139/810x Fast Ethernet Adapter (in PCI port #2)

In the device manager two items come under other devices (yellow question mark): ethernet controller and PCI Device.

Can somebody help trouble shoot? I tried installing a PCI install from Realtek, but had no luck.

A:ethernet controller

Hi Br, and welcome to BleepingComputer.It looks like you have some problems with your drivers. Do you have the CD that came with your motherboard to install the drivers? If not, you can download them from the Gigabyte web site.

Should be on the the motherboard CD (assuming it's a self built).

Otherwise go to the mfg's website and download the ethernet drivers from them, and carry them over with a usb drive.

My old desktop has been running slow for along time so i thought i would completely wipe it and reinstall windows xp on it. It made the computer alot faster but i can't connect to the internet. Im not very good with computers but when I go to the device manager it says that both the Ethernet Controller and the Multimedia Audio Controller are missing, they have yellow question marks beside them. Does anyone know how I could get my internet working? If it helps I have a 1394 Net Adapter Im not sure if that helps at all.

Whats up,
I recently was reinstalling windows xp pro on a friends computer. after the fresh install i tried to connect to the internet..nothing happened. went to the device manager and apparently the the PC wasn't reading the ethernet controller. so i went home to the dell support to download the necessary drivers needed. i even called dell to make sure i was doing the right thing. needless to say it still does not work... i opened up the CPU to try and find the actual name of the ethernet card and could not. there was a small metal box where you put the ethernet cable into. i did not see a card, yet i know there is one. sorry if I'm confusing. its a dell 8300 with no service code or service tag on it. i check inside and out. if you can give me some ideas that would be great. thanks

A neighbor gave me his old Dell OptiPlex 740 with Windows XP installed. I cannot get it to connect to the internet. In Device Manager, I see the yellow splat by the Ethernet controller. Is this something that has gone bad on the motherboard? I can't complain as it was free.

Hello,,,,,THANKS for your time, help, and advise!!!!

Just rebuilt an old IBM Acer/Aspire computer. Rebuilt with the following steps:

o format of C:
o ConvertFat16 to FAt 32, and
o a delivery of Windows 98SE.

And, it runs better than expected.

None of the stuff that was on the machine was required to be saved and no backup was accomplished.

There is a Network Interface Card (NIC) intstalled on this machine and apparently was installed after delivery (not listed in the specifications). The driver diskettes/CD cannot be found. This NIC was working before the rebuild. An attempt to use the computers delivery diskettes and CD could not find a driver for this NIC.

The START/SETTINGS/CONTROL PANEL/SYSTEM/ Device Manager reports the NIC in:

- ?Other Devices
!PCI Ethernet Controller (no driver installed---
also, no conflicts)

"Winipcfg" does not report the NIC so the MAC address to find the manufacturer is not available.

Opening the chassis might reval the manufacturer if it is printed on the NIC circuit board.

If there is a method or a standard driver that can be used to get the NIC to work or some method to show the MAC address then the manufacturer can be contacted to get the driver.

Thanks for your time, help, and advise!!!!
