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.

To stop the Wi-Fi function abruptly, turn off your VAIO computer.

The WLAN standard includes the encryption methods: Wired Equivalent Privacy
(WEP), which is a security protocol, Wi-Fi Protected Access 2 (WPA2), and Wi-Fi
