What should I do if other BLUETOOTH devices cannot connect to my computer?

❑ Check the suggestions in What should I do if I cannot find the BLUETOOTH device I want to communicate with? 

.

❑ Make sure the other devices are authenticated.
❑ The data transfer distance can be shorter than 33 feet / 10 meters depending on existing obstacles between the two 

devices, on radio wave quality, and on the operating system or the software in use. Move your computer and BLUETOOTH 
devices closer to each other.

 

Why is my BLUETOOTH connection slow?

❑ The data transfer speed depends on the obstructions 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 band, with which BLUETOOTH devices or wireless LAN devices work, is used by various devices. Although 

BLUETOOTH devices use the technology to minimize radio interference from other devices that use the same band, such 
radio interference may cause slower communication speeds and shorter distances or communication failures.

❑ If a version of a BLUETOOTH standard employed on the BLUETOOTH device with which you want to communicate is not 

the same version as the one employed on your computer, the communication speed becomes slower.

 

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 to avoid radio interference. Check with facility staff to 
see if use of the BLUETOOTH function on the computer is permitted.
