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? (page
132) .
❑
Make sure the other devices are authenticated.
❑
The data transfer distance can be shorter than 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 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
communications altogether.
❑
Connection capability is affected by distance and obstructions. You may need to move your computer away from obstacles
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.
Why can't I use the services supported by the connected Bluetooth device?
