Notes on Using the Wi-Fi(R) (Wireless LAN) Function
Before using the Wi-Fi function, read the following precautions for correct use.
In some countries or regions, using the Wi-Fi products may be restricted by the local
regulations.
Wi-Fi devices work on the 2.4 GHz band, which is used by a variety of devices. They use the
technology to minimize radio interference from other devices that use the same band;
however, radio interference may still slow communication speeds, reduce communication
range, or cause communication failure.
If both the BLUETOOTH function and the 2.4 GHz Wi-Fi function of your VAIO computer are
enabled, interference may occur and cause slower communication speeds or other problems.
To communicate via Wi-Fi while you are on the road, you may need to contract with a Wi-Fi
connection service provider.
If your VAIO computer is equipped with the IEEE 802.11a/b/g/n standard, outdoor use of the
5 GHz Wi-Fi function is prohibited by law.
The communication speed and range may vary depending on the following conditions:
Distance between devices
Existence of obstacles between devices
Device configuration
Radio conditions
Ambient environment (including wall material, etc.)
Apps in use
Communications may be cut off depending on radio conditions.
The data transfer rate specified in the specification is the theoretical maximum, and may not
reflect actual data transfer rate.
Actual communication speed may not be as fast as the one displayed on your VAIO
computer.
The 2.4 GHz and 5 GHz Wi-Fi frequency bands are not communicable with one another.
The data transfer rate of IEEE 802.11g and IEEE 802.11n (2.4 GHz) may be affected by
interference when used with an IEEE 802.11b product. Also, IEEE 802.11g and IEEE 802.11n
automatically lower the transfer rate to maintain compatibility with an IEEE 802.11b product.
The transfer rate may be regained by changing the channel settings of your access point.
