I just bought a blue-tooth dongle about 2 days ago but for some reason I can't get it to work when my cell phone is 10 feet away . It only works when I am within 1 metre range. According to what it says in the box, the dongle is suppose to provide me with 100 metre range. I was not provided any CD/DVD driver. Is there any other additional settings or changes that I need to perform. I am using windows XP SP3, 32 bit.


Its very small in size (hardly 1 cm long) , can it be due to the size of the dongle ?

These are the actual number from (

* Class 3 radios – have a range of up to 1 meter or 3 feet
* Class 2 radios – most commonly found in mobile devices – have a range of 10 meters or 33 feet
* Class 1 radios – used primarily in industrial use cases – have a range of 100 meters or 300 feet

Despite what is written on the box, the Class type has to be written on the device directly, I suggest you use that reference instead.

Perhaps you should try another OS to see if is it a driver related issue.

I guess the old trick of using half a can of pepsi also applies. (

Nothing about class is written on the box or the device . On the device there is sticker on which numbers from 1 to 12 are printed and on the side. 08, 09 is written.. 09 and 11 are marked in red. The company name advix – SpongeBob SquarePants Feb 23 '11 at 5:48
