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.
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 and the wireless devices (if any).
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 Protected Access (WPA). Proposed jointly by the IEEE and Wi-Fi
Alliance, both WPA2 and WPA are specifications of standards based on interoperable security enhancements that
increase the level of data protection and access control for existing Wi-Fi networks. WPA is designed to be forward
compatible with the IEEE 802.11i specification. It utilizes the enhanced data encryption Temporal Key Integrity
Protocol (TKIP) in addition to user authentication using 802.1X and Extensible Authentication Protocol (EAP). Data
encryption protects the vulnerable wireless link between clients and access points. Besides that, there are other
typical LAN security mechanisms to ensure privacy, such as: password protection, end-to-end encryption, virtual
private networks, and authentication. WPA2, the second generation of WPA, provides stronger data protection and
