I have the same problem on new N5010.

The problem started probably  after bios update to version 12.

I can 't go back to a previous version of bios.  The bios update software refuses it.  Wich BIOS version do you have/use?

I tried new drivers, searching for hours for different solutions. Nothing works, even a complete new install of  the OS. (Windows 7 -64bit)

My BIOS version is Dell Inc. A02.

I dont have any option called Generic Bluetooth Device. And When i try to Install Dell Wireless WLAN, it says "No Compatible Hardware found. The software you are attempting to install is not supportes on this sytem. The software will not be installed. Setup Will exit now." I installed this driver from Dell DVD that comes with laptop.

please tell me guys whether Inspiron n5030 comes with bluetooth or is Bluetooth available in this laptop?

wlan <> bluetooth

That means i have bluetooth hardware in my system. I tried Loging into Dell with my Service tag. I tried downloading my driver from website. But no changes. Now i cant install DW WLAN driver,Bluetooth and Webcam!! I installed Webcam centre but i get message that Webcam driver is not installed.

I got my problem solved. i contacted dell, they said my lap didnt come with bluetooth hardware!!

hello! I had the same problem until several minutes ago :D
I'm running win7 home on dell inspiron n5110
I googled and saw that many people had the problem... search your pc for a device manager -> network adapters
 I have an intel centrino wireless-N 1030 there...so I googled and installed a driver for intel centrino wireless-N 1030
because the dell inspiron bluetooth v3.0+HS or something didn't work, had your error
so..I downloaded it from the dell support site, and had to uninstall some previous versions which I did from the control panel screen
and so I installed it nicely, and now it works :))
anyway, I think the problem is getting the right driver
even the driver from the CD I got with the laptop was the wrong one <.< 

anyhow works now :))

please share this so people can solve the problem, too...I hope it works for others :D
