You need to redownload the drivers for you inspiron N5010 Go to this link: http://support.dell.com/support/downloads/driverslist.aspx?c=us&cs=19&l=en&s=dhs&ServiceTag=&SystemID=INSPIRON_N5010&os=W764&osl=en&catid=&impid=

When you get there Then scroll down Then where you see "Operating System", select your operating system (ex: XP, Vista, or Windows 7). It will then show all the drivers for your operating system...scroll down until you see the network driver software and then download and reinstall the Dell Wireless 365 Bluetooth Module and download the Dell Wireless WLAN 1520 Half MiniCard Hopefully this will help...good luck.

To get the correct drivers for your Dell Inspiron n5010 I suggest you go to the link below. This is the Dell Driver download page. You'll notice that you have 3 options for getting the correct drivers for your computer. The best option is to enter your "Service Tag" number. Usually this is located on the bottom of your computer.

Find the "service tag" code on the back of the laptop, search dell website for drivers for which it will ask for the code. This will load all available drivers for download.

uninstall the driver and try to reinstall it .
when aks for what you said , just switch on the switch for bluetooth .

all drivers are in the CD that came with the laptop....insert the CD and install the HWs

download the driver from dell website and instaled the driver through device manager.

Access the manufacturer's web-site:
