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.
