Sounds like you need to reinstall the driver for your bluetooth device. You should be able to find it on the manufacturers website.

You can try going to Gateway's website and see if they have a support site for driver downloads. I would try this first due to the fact the driver they have would be for your computer. Sometimes the computer manufactures drivers have added abilities not found with on the device manufactures website.
