I HAVE A BUILT-IN NETWORK ADAPTER IN MY COMPUTER FUJITSU, M0DEL FMV 6000CX2 HOW CAN I INSTALL IT AND MAKE IT WORK.


Normally it is automatic enable.
U can see a local network connection (LAN) icon appear under network connection. The icon will show u unplugged if u did not connect to any network or devices.

If u did not see the LAN icon, then u need to check under device manager whether there is any missing driver.

Wireless connection: computer says device unplugged, but it's not. All the settings are correct, but still cannot connect to home network. Used to work before computer software (Win XP Media Edition) was...


Hello Michael,

Windows XP Media Center Edition (MCE) does not normally say cable unplugged. I think you are looking at your Local Area Network (LAN) connection. Make sure your wireless card drivers are installed, and the device is enabled.

1. Click Start
2. Right Click My Computer
3. Click Manage
4. Select Device Manager in Left Column of Newly Opened Window.

Make sure your wireless card does not have a yellow caution sign on it, and make sure your wireless card also does not have a red X. (If you when you select device manager, no devices show that right away, then it should be ok)

If there is a yellow caution sign, you may need to install drivers or your device is having some sort of issue.

If there is a red 'X' on the device, right click the device, and select enable. Again verify there is no caution sign.

Make sure your wireless radio is also turned on.

Let me know if you need further assistance.

As a reminder, if this post helps, please rate it. Thankyou.

Computer doesn't detect printer on installation


is it a usb printer? if so follow this:
Device Manager displays only non-Plug and Play devices, drivers, and printers when you click Show hidden devices on the View menu. Devices that you install that are not connected to the computer (such as a Universal Serial Bus [USB] device or "ghosted" devices) are not displayed in Device Manager, even when you click Show hidden devices.

  1. Click Start, point to All Programs, point to Accessories, and then click Command Prompt.
  2. At a command prompt, type the following command , and then press ENTER: set devmgr_show_nonpresent_devices=1
  3. Type the following command a command prompt, and then press ENTER: start devmgmt.msc
  4. Troubleshoot the devices and drivers in Device Manager.

    NOTE: Click Show hidden devices on the View menu in Device Managers before you can see devices that are not connected to the computer.
  5. When you finish troubleshooting, close Device Manager.
  6. Type exit at the command prompt.

    Note that when you close the command prompt window, Window clears the devmgr_show_nonpresent_devices=1 variable that you set in step 2 and prevents ghosted devices from being displayed when you click Show hidden devices.
If you are a developer or power user and you want to be able to view devices that are not connected to your computer, set this environment variable globally:
  1. Right-click My Computer.
  2. Click Properties.
  3. Click the Advanced tab.
  4. Click the Environment Variables tab.
  5. Set the variables in the System Variables box.

If you right-click the "unknown" device and select Update Driver, you can force windows to search for the correct driver, and then put in the CD or floppy that came with the network adapter, and tell Windows to look on that CD or floppy. If the installation process didn't work, this might.

Network adapter not showing up in device manager


The tech was incorrect - your network adapter is just not recognized by the system. If you install the correct drivers for your particular network adapter it should be recognized, which should then solve your problem. Search the Gateway website for network drivers for your particular desktop, and if the network adapter was added (not built into the computer) then determine the manufacturer and model of your network adapter, then search the manufacturer's website for the correct drivers.

Even easier, if you still have the original disks that came with your computer and/or network adapter, they should include the correct drivers.

Hope this helps!
