Wireless communications
The computer’s wireless communication function supports both Wireless LAN
and Bluetooth devices.
Wireless LAN
The Wireless LAN is compatible with other LAN systems based on Direct
Sequence Spread Spectrum/Orthogonal Frequency Division Multiplexing radio
technology that complies with IEEE802.11 wireless LAN standard (Revision A,
B, G or Draft N).
Supported features. It supports the following features:
◆ Automatic Transmit Rate Select mechanism in the transmit range of 54, 48,
36, 24, 18, 9 and 6 Mbit/s (Revision A and G).
◆ Automatic Transmit Rate Select mechanism in the transmit range of 11, 5.5,
2 and 1 Mbit/s (Revision B).
◆ Frequency Channel Selection (Revision A/Draft N: 5 GHz, Revision B/G/
Draft N: 2.4GHz)
◆ Roaming over multiple channels
◆ Card Power Management
◆ Wired Equivalent Privacy (WEP) data encryption, based on the 128 bit
encryption algorithm (Atheros module type).
◆ Advanced Encryption Standard (AES) data encryption, based on 256 bit
encryption algorithm (Atheros module type).11a, 11b, 11g and 11n wireless
are based on IEEE 802.11a, 802.11b, 802.11g and 802.11n respectively. The
IEEE 802.11n specification has not been finalized and is currently in draft
release. The TOSHIBA 11a/b/g/n Wireless LAN Adapters are based on the
Draft Release, Version 1.0, of the IEEE 802.11n specification. An adapter
with 11a/b, 11a/b/g or 11a/b/g/n can communicate on any of its supported
formats; the actual connection will be based on the access point to which it
connects.
◆ Connection compatibility with the wireless equipment in Draft 11n mode is
not guaranteed.
◆ The Draft 11n function cannot be used with WEP/TKIP. Draft 11n mode can
be used only with WPA-PSK(AES) mode or no security mode.
Security
◆ Be sure to enable WEP (encryption)/WPA-PSK (AES) function.Otherwise
your computer will allow the illegal access by outsider through wireless
LAN to cause illegal instruction, eavesdropping, and loss or destruction of
