HP Pavilion dv9720us running XP can not find the wireless network card. Not an option in the BIOS setup. Downloaded HP wireless assistant 3. Machine recognizes the enable switch. I'm asked to enable the device in the Widows Device Manager but I can't seem to find it!

In the BIOS setup, disable the network as a boot device.

Hello...

I got your issue as the network card is not working in the laptop:

Its is advisable to check with a professional but before this try with the following steps

Step 1: Go to Start

Step 2:Click All Programs and choose Accessories

Step 3:Right click on Command Prompt

Step 4: Click run as administrator

Step 5:Type ipconfig/release and when that finishes type ipconfig/renew

If the HP Pavilion ZD8000, ZD7000, ZD9000 wireless card still can’t work, you better check the BIOS setting.

Commonly after install the new operating system the wireless card setting was turned off in the BIOS automatically.

Hope this would help you

With regards

Uninstall and reinstall wireless driver.
Update BIOS and then check for the issue.
Download and HP Wireless assistant.
Incase, if the notebook still does not connect to wireless networks then remove reseat the wireless card and check for the issue.

make sure you have a good driver and that it is the correct one for your computer then uninstall reboot then reinstall.
hope this helps.

Try following this, XP, Vista, and Windows 7 seem to run into this problem.
It will remove the high and low filters, forceing the machine to regenrate and it somehow finds the drive again.

link to drivers for wireless for xp : ftp://ftp.hp.com/pub/softpaq/sp36501-37000/sp36770.exe

I was unable to locate appropriate drivers for either of the sound systems on that model from the HP website, but you should be able to get them through the Windows Update site. Just make sure you choose the Custom button (Express only looks for critical updates) and check the drivers section to see what is available for you. I know for sure the RealTek drivers are there and I would assume that the Conexant drivers are as well, so you should be covered no matter which specific hardware configuration you have.

in the BIOS you should change the following option

sata native mode should be disable.

Your wireless zero configuration being manipulated by the add-on service of manufacturer software. first you can manually turn in the Wireless Zero Configuration by typing services.msc on run menu. After you run the services you will see Wireless Zero configuration please enable and start it with the given option.

Next you can open the Wireless Network Connection option, uncheck the add on protocols, such as AEGIS and WLAN protocol. after restart computer should work with wireless without problem.

Please post if you need further assistance.

Good Luck
