Hi,

I would suggest checking the model of the network card. Once you find out see if you can find it on this site:

There are two ways to install the driver:

Install the driver using the wizard.

Forcely install the driver

Steps:

Right click on the icon that has the yellow mark
Click update driver
Choose install using specific location
Open the driver location
Then proceed to the Installation
Last restart the computer and check if you got still the yellow mark.

Note: Check the operating system and the adapter maybe there is a compatibility issue.

There is a known problem and being out of warranty isn't the end of it. You may be able to get them to fix it or try this yourself.

There are Vista and XP versions of the installers and the drivers and the bios is different depending on whether you have an AMD or an Intel processor, so be careful which items you attempt. Good luck.

On mine, I had to update the bios, uninstal the old hp wireless assistant and uninstall the wireless driver from My Computer (right mouse click) Properties - Device Manager - Network Adapters, then I installed the latest HP wireless assistant from above page and the latest Intel wireless adapter from above. Check the position of your wireless switch on the front lip of the laptop. One way should make the light go blue, for on, the other shows amber for off. If you are in the bad state pre fix, both positions will show amber. HP assistant will show the device is disabled, but you won't be able to do anything for it as there will likely be yellow tags on all the network adapters.
Mine works now, but I'm having other issues with installing SP1 for Vista. Anyway, hope this helps

You can use a wireless network to share Internet access, files, printers, and more. Or you can use it to surf the Web while you're sitting on your couch or in your yard. Plus, it's easier to install than you think.
There are 4 steps to creating a wireless network:
1.
Choose your wireless equipment
2.
Connect your wireless router
3.
Configure your wireless router
4.
Connect your computers
For Windows XP users, Windows XP Service Pack 2 is not required for wireless networking, but it does make things much easier. Service Pack 2 also helps protect you against hackers, worms, and other Internet intruders.

Connect your computers
If your computer does not have wireless network support built in, plug your network adapter into your USB port, and place the antenna on top of your computer (in the case of a desktop computer), or insert the network adapter into an empty PC card slot (in the case of a laptop). Windows XP will automatically detect the new adapter, and may prompt you to insert the CD that came with your adapter. The on-screen instructions will guide you through the configuration process.
Note: The steps below only apply if you're using Windows XP Service Pack 2. If you're running Windows XP and you don't have Service Pack 2 yet, plug your computer into your wireless router and download and install Windows XP Service Pack 2.
Windows XP should show an icon with a notification that says it has found a wireless network.
Follow these steps to connect your computer to your wireless network:
1.
Right-click the wireless network icon in the lower-right corner of your screen, and then click View Available Wireless Networks. If you run into any problems, consult the documentation that came with your network adapter. Don't be afraid to call their tech support.
2.
The Wireless Network Connection window should appear and you should see your wireless network listed with the network name you chose. If you don't see your network, click Refresh network list in the upper-left corner. Click your network, and then click Connect in the lower-right corner.
3.
Windows XP prompts you to enter a key. Type the encryption key that you wrote down earlier in both the Network key and Confirm network key boxes, and then click Connect.
4.
Windows XP will show its progress as it connects to your network. After you're connected, you can now close the Wireless Network Connection window. You're done.
Note: If the Wireless Network Connection window continues to show Acquiring Network Address, you may have mistyped the encryption key.

if you have a windows xp disc when you start to install it it will have to format it first by default unless you ask the cd to repair windows in which case it just over writes the files and registry
