Setting up security functions for the wireless network
Wireless networks are even more susceptible to eavesdropping than wired networks.
With conventional network adapters, an intruder only needs a device with a WLAN
adapter (e.g. a notebook or a PDA [Personal Digital Assistant]) with an appropriately
configured network card in order to eavesdrop on every communication made via a
nearby wireless LAN.
The Giga762SX WLAN dsl makes use of effective encryption methods to prevent unau-
thorised eavesdropping as far as possible.
The Giga762SX WLAN dsl is delivered with preset individual encryption (WPA2-PSK/
WPA-PSK with pre-shared Key). You will find this key at the label on the devices bottom.
If all components of your wireless network provide this encryption method there is no
need of any settings in this screen. If not, or if you want to change the preset key (e. g.
if unauthorised persons may have access to your device), you can configure the encryp-
tion for your wireless network in the next step.
You can use the following security mechanisms:
u
WPA2-PSK, WPA-PSK or WPA2-PSK/WPA-PSK (page 54)
u
WEP encryption (Wired Equivalent Privacy, see page 56)
You will find further options for setting up data encryption and authentication in the
Advanced Settings
menu (page 87).
WPA2/WPA with pre-shared key (PSK)
WPA
is a more advanced procedure than WEP for protecting wireless networks. Dynamic
keys, based on TKIP (Temporal Key Integrity Protocol), offer increased security. The new
standard WPA2 uses
AES
(Advanced Encryption Standard) for encryption.
