Troubleshooting
Can I use a device with Bluetooth technology on airplanes?
With Bluetooth technology, your computer transmits a radio frequency of 2.4 GHz. Sensitive locations, such as hospitals and
airplanes, may have restrictions on use of Bluetooth devices, due to radio interference. Check with facility staff to see if use
of the Bluetooth functionality on the computer is permitted.
Why can't I connect to a Bluetooth device by specifying its IP address on a Personal Area
Network (PAN)?
The Bluetooth utility software uses Dynamic Host Configuration Protocol (DHCP) to assign IP addresses to active wireless
devices. If you specify a fixed IP address for the device to which you want to connect, the utility cannot assign a dynamic IP
address to the device and fails. Do not specify IP addresses when using a PAN.
Why can't I use the Bluetooth functionality when I log on to my computer as a limited user?
The Bluetooth functionality may not be available to users with limited rights on your computer. Log on to the computer as a
user with administrator rights.
Why can't I connect to a Bluetooth device in Personal Area Network User mode?
If the device to which you want to connect supports Bluetooth communication in Personal Area Network User mode only, you
cannot establish a connection from your computer.
Why can't I use the Bluetooth utility software when I switch a user?
If you switch a user without logging off from your system, the Bluetooth utility software will not work successfully. Make sure
to log off before switching a user. To log off from your system, click Start and then Log Off.
