Is there an unknown device on the device manager? This might be the wireless card. You might check the windows 7 drivers for your computer on this site: http://h20000.www2.hp.com/bizsupport/TechSupport/D
Hope this helps.

I am having problems with my 6715b too. I can't get the wireless to come on. I tried to look up my wireless on device manager and it doesn't even show the wireless card. My wireless used to work. I was able to download the driver for it. sp45524.exe from the website. I am using windows 7 32 bit. Any help would be appreciated. I'm all tapped out on ideas.

It's a well known chipset defect.
Nvidia chipsets uses to get damaged. A design defect in the cooling system make all this notebook generations to die. The chipsets gets overheated and starts to fail loosing "the wifi" in first instance,, and ends with a general failure due to the damage generated, in the chipset, by the overheat.
Thanks HP, you find a way to make your products life shorter than usual, I still using HP, i like them, but this failure is really annoying.

There's not a problem with hardware here. Again it's microsoft's fault
I had the same problem with my hp 6715b and after reinstalling the windows 7, everything worked fine for a while. Then I installed windows updates and the wireles wouldn't turn on again and it wasn't shown in the device manager even if I tried to reinstall the driver.
An interesting fact was that although I couldn't acces the internet and the wireles and cable LAN adapter couldn't be installed, I could still choose an update from windows update center and windows downloaded it and installed it. Go figure..
Then I reinstalled the windows and installed only the drivers and Slovenian language pack. I also turned off windows update and wireless adapter works like a charm..
