■
The values shown above are the theoretical maximums for Wireless
LAN standards. The actual values may differ.
■
The transmission speed over the wireless LAN, and the distance over
which the wireless LAN can reach, may vary depending on surrounding
electromagnetic environment, obstacles, access point design and
configuration, client design and software/hardware configurations. The
transmission rate described is the theoretical maximum speed as
specified under the appropriate standard - the actual transmission
speed will be lower than the theoretical maximum speed.
Security
■
TOSHIBA strongly recommend that you enable WEP (encryption)
functionality, otherwise your computer will be open to illegal access by
an outsider using a wireless connection. If this occurs, the outsider may
illegally access your system, eavesdrop, or cause the loss or
destruction of stored data.
■
TOSHIBA is not liable for the loss of data due to eavesdropping or
illegal access through the wireless LAN and the damage thereof.
