    Dear Mr. Keepwaling,
    Thank you for this solution. I followed your instructions, but got confused when you spoke of extracting to the LAN folder. I did an explorer search and could not file any folder by that name. I did save it to my flash drive and then ran the exe file. So far,no change in my ethernet question mark ! icon.

    Is there any way to check on the ethernet connection'sfunctionality before I head out to get a PCI network card?

    Thanks, The solution was very well thought oout and articulated. It did pertain to my Gigabyte motherboard and the model I had, so it isn't that I took your solution and was trying to solve another motherboard's problem. Thanks for your expertise.

Hi keepwalking,
There are three revisions for this board. Please click on this link for the correct version number.

Create a folder on you're desktop & name it Chipset. Listed on the right side of the above page is Drivers. Click on the word Drivers. Next, under Chipset click "Download from". Pick a site to download from & save the download file into the folder you created on you're desktop. The file is compressed. Open the chipset folder & double left click the .exe file. Extract to within the LAN folder. Once finished. Open device manager. Find the yellow ! point for you're LAN controller/driver. Right click on the yellow ! point once & left click update driver. Windows hardware wizard will open. Click No, not at this time. Than click the next button. Another window will open. Left click once in the circle next to, Install from a list or specific location (Advanced). Than click the next button. Again, another window will open. We want to remove the green check mark next to, Search removable media (floppy, CD-ROM...). Click the green check mark once & it will go away. Click the Browse button. . Another window will open. (Browse For Folder). Click the + sign next to My Computer. Find the folder chipset on you're desktop. Open it.
Open the folder, INFUpdate & run the .exe file.
This will re-install the updated chipset drivers for you're Gigabyte board. Make sure you restart before testing you're internet connection. If the update fails to remove the yellow ! point in device manager you're onboard LAN controller may be defective.
It is suggested you call Gigabyte if you're board is still warranted. If it is not warranted buy & add a PCI network card.

Good Luck!
If I can help you further, feel free to post.
Suggestions & comments welcomed.

Dell dimension 1100 DE051 Internet drivers are installed All connected successfully Internet will not work Please help

Check that all drivers are installed and working in device manager as when I reinstalled Windows not all of the drivers installed and I had to do it manually. These drivers were the ones that give you access to the internet. These were network adapters and IDE ATA /ATAPI controllers.

Hope this helps.

If your device manager indicates a good network adapter, wireless and/or Ethernet, go to the Dell website, select support, drivers and download, and enter your service tag number. It will direct you to all the drivers you need to get you computer operational again. If the device manager indicates missing network adapter drivers, you will need a flash drive, a computer that can connect to the Internet, and transfer the network adapter driver to this computer.

Try going into the control panel and then into the device manager. Find the ethernet device and remove it. Then re-boot the computer and the OS should re-detect the card and re-install the drivers. Hopefully this will get the card working again. Let me know if this helps.

Network Adapter/Ethernet Controller

Nothing wrong with having two network adapters installed on your computer. If you have this DWA-552 wireless adapter installed as well as an onboard NIC, the correct thing to do is have both drivers installed so you see them both in your Control Panel->Network Connections window.

If you really want the onboard nic to go away, go into device manager and disable it - not uninstall it.

Compaq presario broadcom adapter not showing


I will assume that your broadcom adapter is not showing up under Device Manager > Network Adapters. It will happen if the driver is not properly installed.

Look for "Other Devices" under Device Manager. Usually, it will show as Network Controller or Ethernet Controller. Right click that and select update driver. Make sure that you have the driver or file for that adapter. Once the driver is properly installed, it will be under Network Adapter with the correct name.

I hope that helps.

Good luck and have a nice day!
