The data transfer speed depends on the obstacles and/or the distance between the two devices, on the radio wave quality, and on the operating system or the software in use. Move your computer and Bluetooth devices closer to each other. . The 2.4 GHz radio frequency used by Bluetooth and wireless LAN devices is also used by other devices. Bluetooth devices incorporate technology that minimizes interference from other devices using the same wavelength, however, communication speed and connection range may be reduced. Interference from other devices may also stop communication altogether. . Connection availability is affected by distance and obstructions. You may need to move your computer away from obstructions or closer to the device to which it is connected. . Identify and remove obstacles between your computer and the device to which it is connected. . Note that due to limitations of the Bluetooth standard, large files may occasionally be corrupted during continuous transfer due to electromagnetic interference from the environment. Why can't I connect to service supported by the target Bluetooth device? Connection is only possible for services also supported by the computer with the Bluetooth functionality. For more details, see the help file on the Bluetooth utility software. 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. 165nNTroubleshooting 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 onto my computer as a user with a standard user account? The Bluetooth functionality may not be available to a user with a standard user account on your computer. Log onto 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 your system, the Bluetooth utility software will not work successfully. Be sure to log off before switching a user.
