Preferred Solution: Solved: missing ethernet controller network controller PCI Modem

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

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!

A:Missing Ethernet controller and PCI simple communications controller

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.

Hope this helps.

Hi again

I replaced the HDD on my NB510-109 and installed W7 prof 32 bit. Unfortunately Windows has no Driver for my Ethernet and Network Controller. The Ethernet vendor is 1969 (Atheros) but the Driver I've found doesn't work.

The Network Controller vendor is 10EC (Realtek or Acer) but I can't find a Driver.

Is there a link where I can load the original Driver CD/DVD?

PS: I couldn't save the original data from my old HDD because the HDD failed complete.

A:NB510-109 - Missing driver for Ethernet and Network Controller

Are you searching for LAN driver or WLan driver?
I?m asking because the Network controller could mean WLan or LAn card.

However, the notebook supports the Atheros LAN card and you should install the Atheros LAN driver.
The WLan card is made but Realtek. Its RTL8188CE 802.11bgn Wlan card.

On the Toshiba EU driver page you can find two Atheros LAN drivers for Win 7 32bit:

I recommend you to check both.

The Realtek WLan driver could be downloaded from Toshiba WLan portal:

I did a windows 7 clean install on my HP Mini 210 4051 nr as part of creating a dual boot with Ubuntu. In Linux the internet works fine, but in Windows 7 it does not. In the device manager I see yellow flags over the ethernet and network controllers. Code 28 (My model does have an ethernet port).

Because the machine cannot connect, I downloaded all the related drivers (everything from the network tab) from the HP website for my model with another computer and then put them all in a folder on the Mini's desktop via USB. When I try to install the drivers through the device manager, and direct it to that folder, it says it finds nothing usable.

Here are the IDs

Ethernet Controller

Network Controller

Any suggestions will be appreciated!

Instead of pointing device manager to those files, have you tried just running the .exe files you downloaded?

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)

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.

just upgraded my Dell Inspiron 9300 laptop from windows xp to windows 7 Home Premium. The multimedia Audio Controller and Network Controller are missing and I can't connect to the internet. How can I download these drivers to a flash drive and then install on my laptop

A:missing multimedia audio controller and network controller

Have done some looking around. From what I have found in many forums is that Vista drivers should work with Windows 7.

Post at Dell forums says the Sigma Tel Stac 975X AC97 audio driver listed for the Insperion 9300 at Dell Support will work for Vista and Windows 7. The file is a zip, so downloasd and save the file to the flashdrive. Then load it on your laptop, unzip and run it.


None of the Netwrok dirvers at Dell Support are for Vista.

For the network controller I would suggest going to the Dell Support and find out what the original configeration was for your system. Go to this page, select Original Configeration tab and enter the Service Number for your computer. It will e on a tag on the bottom.


Once you get your network divices names, go to the device manufacturer's site and check for Vista/Window 7 drivers.

Hi guys,

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

I reinstalled Windows and everything seems okay except for one problem..

It won't connect to my router through Ethernet because, apprently I haven't installed my Ehternet Controller drivers.

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

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..

Still can't access the Web and the Ehternet Controller aspect in the Device Manager still has the yellow question mark next to it.

Can anyone help shed any light?


PS. This is a custom computer I bought some time ago.

The ethernet controller on my PC (a HP) was accidentally uninstalled and now I can't access the internet on my PC... From memory I think the controller was called a "Realtek Ethernet Controller".

I have tried downloading a realtek driver listed as a h1r106ww on my laptop and transferred it to the PC via a flash drive to try and fix this, but when I click to install it, it tries and of course fails, to access the internet to do the install.

Help, how can I install an ethernet controller on my PC when the PC doesn't have access the internet?

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

any thoughts would be appreciated.

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.

Hi everyone, found this site by searching for an answer to my question which has had me stumped for a week now. Basically, I got the blue screen o' death and had to wipe the partition and re-install XP SP2 from my Recovery Disk provided by ibuypower.com with my HEL-80 laptop.

I installed every driver from my supplied CD in order as I'd lost my backups in a recent move. Everything works fine, except: Wireless Internet and Ethernet Controller (Question Mark, driver cannot be found any way I've tried) and my Intel 82801G (ICH7 Family) USB Universal Host Controllers: 27CA, 27C9 and 27C8 as well.

The USB issue isn't my priority, but the wireless internet is. I even re-installed XP SP2 a second time, re-installing all drivers to see if I missed something. The card listed on my CD is a Intel Golan 3945ABG, I've downloaded the drivers and it still doesn't appear under my 1394 Net Adapter nor my PCI-E Nic Card either.

I've already contacted the company I purchased the company from and am trying to get in contact with Intel to resolve this issue. I copied the Belarc System Advisor sheet to notepad, and will attach it to this post for a full measure of everything I have. Hope you guys can help, this has stumped quite a few people I know that are fairly good with computers!

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.

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

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 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

A:Missing Ethernet Controller

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.

Sorry for posting in two forums - thought after writing that this was a better place.

We can not get on line with our home computer (dial-up). The computer dials out, the modem at our ISP picks up and then hangs up - Error 720.

Looking at Device Manager -
The modem shows as working
Network Adapters shows -
Uli PCI Fast Ethernet Controller - under Properties is shown as working properly
Uli PCI Fast Ethernet Controller - Av FW Packet Filter Miniport - shown as not working
WAN Miniport IP - AVFW Packet Filter Miniport - shown as not working

The last two were installed by Avira Antivirus, a program which we have uninstalled.

Can I download support files for a network adapter?
Windows XP SP3

A:Solved: Missing/Broken Network Controller Adapter

Try ...

TCP/IP stack repair options for use with Windows XP with SP2 or SP3.

Start, Run, CMD, OK to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Hey, I'm quite a beginner when it comes to computers, but I do know these things:

Under <Device Manager> the Network Controller has a yellow triangle icon with an exclamation mark, and as for the network adapters, I only have two bluetooth, and one Marvell Yukon Ethernet.

Now, I just got a new hard drive, and I completely reinstalled a clean Windows 7 Home Premium. Therefore, I'm rather sure that my drivers are missing.

My laptop is a Samsung NP-R780-JT01US
I have downloaded (Edit: AND installed) all the drivers, yet the network controller still does not work, and I still don't have any wireless Network Adapters.

I would like to know if this means that my NIC is broken, or if I simply need the right driver. I have tried to update the drivers, but finding them online seems to be impossible and I have no CDs or backups.

What are my options?

Thanks, CubinJ.

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.
