Setting security functions for the wireless network

In the next step you can set the encryption and authentication methods for your wire-
less network.
Wireless networks are even more strongly exposed to the risk of 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 Gigaset SE361 WLAN uses effective encryption methods to largely prevent eaves-
dropping.
You can use the following security mechanisms:
u
WPA2-PSK or WPA2-PSK / WPA-PSK (see page 34)
u
WEP encryption (Wired Equivalent Privacy, see page 35)
We recommend using WPA2-PSK if it is supported by all components in your wireless
network.
Note:
If WDS is enabled (see page 62) only WEP is available as encryption method.
You will find further options for setting data encryption in the Advanced Settings
menu (see page 58).

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 Integration Protocol) offer increased security. The
new WPA2 standard uses AES for encryption.
WPA-PSK is a special WPA mode for users at home and in small companies without a
company authentication server. Encryption keys are automatically generated with the
Pre-shared key, automatically changed ("rekeying") and authenticated between the
devices after a certain period of time
Note:
Every PC (network adapter) that requires access to a wireless network protected by
WPA must also support WPA. To find out whether and how you can use WPA on your
PC, read the user guide supplied with your network adapter.
ì
Select the WPA2-PSK option if it is supported by all components in your wireless net-
work.
or
ì
Select WPA2-PSK / WPA-PSK if some or all components in your wireless network
support WPA with the TKIP protocol.
