Missing Ethernet Controller and SM Bus Controller

Q: Missing Ethernet Controller and SM Bus Controller

Hi guys,

I have a slight problem with one of the PC's..

I reinstalled Windows and everything seems okay except for Two problems..

There is a yellow question mark next to my Ethernet Controller and SM Bus Controller in Device Manager.

I'm not exactly sure how I find out what Ethernet Controller or SM Bus Controller I use to go and download the drivers.

Here are my computer specs:

Intel® Core™ 2 Duo E6750 Dual Core Processor(2.66GHz,4MB Cache,1333MHz)

PCI-Express Mainboard - Pentium® D/Core™ 2 Duo - Micro ATX
2GB DDR2 667MHz Memory - (2x 1GB)

Sapphire HD 2900 Pro

Xp Pro

Preferred Solution: Missing Ethernet Controller and SM Bus Controller

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.)

A: Missing Ethernet Controller and SM Bus Controller

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.

Hi there, this is my first post on the forum as I found this site while browsing on my iPod. Now why would I have to use my iPod when I have a beautiful new computer sitting in front of me? Well as the title says. I have no controllers, ergo, no Internet.

I bought it second hand, absolutely nothing wrong with it, I think he just might of went too far when he wiped it before giving it to me.

So, I came here hoping you guys could rescue me... I'm looking for the driver(s) I need, and I'm also wondering how I can manage to download them to my com if it's not online. I have;

System Manufacturer: Gigabyte Technology Co., Ltd
System Model: H55M-S2
OS: Windows 7 Home Premium 64bit (6.1 build 7600)
Processor: Intel Core i3 CPU 540 @ 3.07ghz (4 CPUs)
BIOS: Award Modular BIOS v6.00PG

I'm hoping that's all good, I read it all of my DxDiag. Thanks In advance for the help!

Welcome to Windows Seven Forums!

I found all the drivers at the Gigabyte website for Windows 7 64 bit including the ethernet controller. If you have access to another machine you could copy any drivers you need onto a USB flash drive then copy them to your machine.

I have a Dell XPS M1210 and when I start my computer, it prompts me to install the software for the Ethernet Controller. I don't have the CD that came with the laptop anymore. I was wondering if anyone could help me find a driver or find the software I need online so that I can install the ethernet controller? Thank you!!

Go to Start/Run and type devmgmt.msc and press enter. In the Device Manager any device with a yellow mark needs a driver installed. On an internet computer download the Broadcom Ethernet Controller and any other drivers you need from the Dell site, Save it to a USB flash drive and transfer it over to the non internet computer.

Hello guys, I have recently reinstalled my OS and my ethernet controller driver is not installed. I can not connect to the internet to find an update to the install it, and likewise, I do not know what driver it is I need to install. The computer itself is an ancient artifact of dell manufacturing... it is a dell optiplex gx520

A:Ethernet Controller missing

The GX520, which I am running right now with Windows 7 and all its eye-candy, is, to me anyway, an amazing piece of machinery.

So, I probably have the driver that you need. What does Device Manager show for problem devices?

I have an Acer 603G "upgraded" to Win 7 Pro thanks to this forum.
My current issue involves my ethernet controller. It is missing, when I go to Device Manager (DM) the statement where the ethernet controller once existed now reads "Unknown Device". This started when I unsubscribed from software I discontinued. At first the ethernet controller was disabled, I was able to re-enable it from DM. More recently it disappeared from DM and I was able to re load the BIOS and it would work as of two days ago that doesn't help. The BIOS is P11._B2_A. I have downloaded new BIOS onto a pen drive and this still does not correct bring it back.

Hello Experts,

My computer (Dell Dimension 8300 running Windows XP Home Edition) is missing these things in the device manager.

Ethernet Controller

Multimedia Audio Controller

SM Bus Controller

Video Controller

Video Controller (VGA Compatible)

All of these come up with yellow question marks next to them.

I have a dell resource cd which came with my computer. The cd is labeled drivers, yet I can not seem to find what I'm looking for on this cd.

What I REALLY want. Is to install this ethernet controller, so that my computer can recognize my modem( hooked up to my computer via ethernet cable), so I can get online and just update all of my drivers and take care of this mess.

I can't find anywhere on the cd that has anything to do with ethernet controllers though.

There is one thing called a Broadcom Driver on dells website, which has to do with NETXTREME GIGABIT ETHERNET. I've also found this on the driver cd, and installed it, but the ethernet controller still has the question mark after restarting the computer. Its the only thing on the cd that has the word ethernet in it.

Could someone help me find an ethernet controller online that I can download to my laptop, copy to an external hard drive, and install on my desktop computer so I can reinstall my yahoo sbc dsl modem and get online.

Could you also tell me how to install it if I have to do it manually without a wizard to guide me.

Thank you very much for your time. I'm in a real bind ... Read more

If you're DSL you should have a USB connection port. Unplug the Ethernet cable and try getting online with USB. You should be able to download the drivers you need.

A:Ethernet Controller Missing

I'd suggest downloading/installing the drivers for the Intel NIC (from the HP drivers site).

You don't tell us what is installed on this system...so I don't think you have a gigabit NIC. From what I see, that would be a PCI-e connection for that, while I suspect that you just have the normal onboard ethernet connection.

Unless you know for sure that you have a gigabit ethernet connection, you should not assume it where options are available.

Someone reinstalled Windows XP on my son's computer, and now it is not working properly, so I am trying to help get it fixed. I have limited experience with this sort of thing. The specs on the computer are as follows:
Acer Aspire 5050-3371
AMD Turion 64 Mobile Technology MK-36 (2.0 Ghz 512 KB L2 cache)

It will not connect to the internet, and when you check the Device Manager, it gives a yellow question mark under "Other devices". The other devices that have question marks are:
Ethernet Controller
PCI Device
PCI Flash Memory (3 times)
Universal Serial Bus (USB) Controller
If you look under properties for the Ethernet Controller, there is no information. It says Manufacture Unknown, OCI Bus2, device 0, function 0.

Under the Local Area Connection Status it says limited or no connectivity. However, in Properties it says that it is a "Realtek RTL8139 Family PCI Fast Ethernet NIC. It says the device is working properly.

Can you tell me what I need to do to get this computer fixed? It has many problems, but getting it to work on the internet would be the first problem to solve.

I've tried shutting it down and rebooting, and that doesn't help. I've tried to renew/repair the internet connection, and that hasn't worked either. I think the ethernet is the key, but I'm in the dark here.

Thanks for your assistance.

I recently reinstalled windows on my computer due to a series of crashed and the win32 virus, i used my factiry CD.
I use the Windows XP Media Center Edition, my machine is an eMachines W3507
At the begginning, i had the all famous NTLDR is compressed message, so i could't go anywhere from there, so i switched my hard drive from class selective to slave, and only then was i able to reinstall windows.
It was all going well until i tried to go on the internet, i said that my ethernet controller drivers were missing, and so were the drivers for my pci modem, so after 2 weeks of downloading and installing the incorrect drivers for my ethernet controller, i gave up and now i find myself typing this message.
I have lost all hope on the fools at eMachines customer service, because they just tell me to call some guy in India, and he tells me to give him my credit card number, because i never put my coomputer on a waranty.

Does anybody know a website where i can download these drivers, or someone who can help me?
Any help would be gratefully received
thanks in advance

Hi There

I am having an issue with my computer. I went on vacation about a week ago, shut down my computer, came back, my computer was running(I can only assume family had been using it) and it could not access internet.

I was using a DSL modem with a USB connection.

I moved, am trying to set up at new house with a cable modem.

The problem appears to be missing drivers for ethernet controller and "USB Cable Modem",

I am running Windows XP Pro on a custom built machine

Mother Board is


I have downloaded/installed chpset drivers from mfg website and they do not fix the problem.

I have tried to install USB Drivers for Cable Modem and it requests that I install USB Drivers first

I am using Other USB Devices so I assume that my USB drivers are intact, and this is simply a networking driver issue.

I have tried uninstalling the hardware from the system and attempting to let windows reinstall it without success

Any suggestions? Could this be virus related?

A:Ethernet Controller Missing Please Help - Compaq


After delving into several areas of the HP website (plus some other very reliable sources like computersurgeons.com,) I basically concluded that your controller is NOT Win7-compatible.

Basically, when a driver (ethernet for example) is in the form of a text document (.inf, .sys, etc.,) typically you can count 10 lines down from the top (after opening it) and changing the coding. (example: realtek = value of 8187 is now 8197 for vista compatibility. However, the specific driver you need only comes in a Windows Installer-based module. It's considered firmware; bottom-line, it's impossibe from a consumer standpoint to force "forwards-compatibility" before they're ready to provide it.

In one specific area of HP.com, they actually (laughably) said to use Windows/MicrosoftUpdate.

It's definately recommended that, since you went through the trouble to reformat, that you get a second opinion, but I will definitely put my money on the fact that this specific controller is designed for an XP platfom. (Also, FYI, Vista compatibility just became available recently...)

Your last option could be to contact tech support directly or find a way to get ahold of them withOUT paying their outrageous service fees. Here's one place to start: HP Support & Drivers

Also, a secondary option would be to download HP's proprietary diagnostics utility for your hardware. Google (with quotes) "HP Hardware Diagnostic Tool"; It should, at worst, run as an Active... Read more

I'm not exactly sure how I find out what Ethernet Controller I use to go and download the drivers, so I looked under 'Network Adapters' also in Device Manager and it listed is as 'RealTek RTL8139 Family PCI Fast Ethernet NIC'.

I downloaded these drivers from RealTek and installed them on the troubled computer but to no avail..

I just got high speed internet at work and when i tried to hook up to the main computer I can't get it to work. i know the DSL is working as I got the wireless to work and hardwired to a laptop and it works.

The ethernet controller is missing. i don't know why. it might be i reformatted the computer a while ago and as i was on dial up I did not miss it. but i don't recall reformatting.

i went to the Gateway site and see no drivers available there for the computer. as the ethernet is built into the motherboard i guess i have to go to Intel to get that. but i have no clue exactly what i am looking for there and don't want to download the wrong thing. i looked but there was nothing obvious.

it is the 915 series

This system was a contract model until recently. I put the established image onto the system but it was missing the Ethernet Controller driver. As the system was newer then the image I decided to image it from scratch with the latest drivers. Still the Ethernet Controller is missing. The system is running WXP Prof SP2.
The LAN card is working fine. I've mapped drives and run Windows Update. I installed the Modem driver from HP but the modem is not appearing in the Device Manager. I presume the missing driver refers to the modem.
I have uninstalled the device, but the driver was not picked up on reboot. I have pointed it at the inf files but it doesn't liked them. I have installed older drivers but it makes no difference. I reinstalled the chipset but it didn't change a thing.
I am at my wits end. I have had trouble with every single model of HP we have ever had and I hate having anything to do with them. But I have to fix it. Any advise would be very much appreciated.

For some reason the Ethernet controller drivers decided to complain earlier today, for the first time with an irritating yellow exclamation mark sign, I was wondering if the nice people at TechSupport could direct me to the drivers I need, I went into System Information and on to the adapter, it says "WAN Miniport (SSTP)". I've been trying a plethora of things, like installing new chipsets, but instead I was landed with Easytune, which isn't all bad. I guess.

Hello, I am trying to help my parents to fix their computer. Their internet connection stopped working. They have Windows XP Professional. I tried several things to fix the problem to no avail. Finally I checked the device manager and found that the Broadcom NetXtreme Gigabit Ethernet controller was missing a driver. I have downloaded several drivers and tried to install them, but the process never works. I think in the process the controller was deleted, but after running a plug and play search, the controller was found, but now it says there is no software available. On a related note, in the same area it says there is a serial bus controller missing. I know this is an usb, but not sure if it is important or even related. They are also having some issues it seems with the modem. The send light doesn't come on and internet access is sporadic. It has been a very frustrating factor in trying to find a solution to this problem. Any help you can provide would be much appreciated. Thank you.

After computer crashed, I ran WinXP reinstall CD. Of course, I lost everything that was previously loaded. I'm going again but have no sound. In Device Manager under Other Devices, Ethernet Controller & Multimedia Audio Controller are yellow question marks. I have tried the Resource CD, Dell Support/Downloads, everything I can think of and nothing is working. I am connected to the internet through the USB because the tech says I need a new ethernet card and have to connect right now through the USB. I'm lost at this point. Any assistance is greatly appreciated.

What is the make and model of the PC?
It sounds to me you just need the drivers for the sound and network.
Have you done a full MS Update?

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.

Please keep in mind that EVERYTHING works fine except that I get the three notifications from new hardware found windows utility. If anyone can he... Read more

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?).

Thanks again for any help.

I got a HP Compaq dc7700 Desktop that I can't find the right drivers for my internet connection. I've installed Windows XP Pro SP3 on this machine. It did not come with it and I did not get any original disk when I bought the machine from Comp USA. This machine was a refurb with XP Pro on it. I have been to HP's site and entered the product number and download the network drivers they have listed for it. So far none have allow me to connect. I get the diagnostics tool that says it can't find the hardware. I have installed a 500G sata HD and still have the 160G that came in it on drive "E". What options do I have? Can I somehow copy and paste the original driver from the old drive to the new and if so where do I find them on the old drive and where would I put them on the new drive? Thanks for any help in advance.

I cannot connect to the internet via an ethernet cord. I suspect it is because my HP Pavilion dv9260nr Notebook PC (Windows Vista 64-bit) is missing its Ethernet Controller Driver, or so says the Device Manager. I have tried different ethernet cords and different ethernet wall jacks. When I plug an ethernet cord into the slot on my laptop, it lights up, but no wired internet connection shows up in the Network and Sharing Center. My computer can connect to the internet wirelessly, as it is doing now at Starbucks. These are the Ethernet Controller Driver's hardware ID's, according to the Device Manager:


I have been to HP's website and found the page specific to my model:


However, under the drivers section, I couldn't find anything that looked like an ethernet controller driver. I have tried having the Device Manager search automatically for the driver, no dice. I don't have my original system install disk, I left it back in America (big mistake). The device manager says that it's provider and manufacturer are "unknown." I don't want to keep coming back to Starbucks, the coffee in Chinese Starbucks is more expensive for some reason.

I have no idea what to do at thi... Read more
