Setting up wireless security

To protect your wireless network, you need to setup a security mechanism on your

WiFi-AP @n.

Network authentication

Network authentication uses certain types of mechanism to identify authenticated

wireless clients. WiFi-AP @n supports the following authentication methods:
Open system:

This option disables authentication protection for your wireless

network. Under the Open mode, any IEEE802.11b/g wireless

client can connect to your wireless network.

Shared key:

Shared means using the same WEP keys for authentication

and encryption.

WPA-PSK:

WPA-PSK (Pre-Shared Key) is the solution for home and

SOHO users who have no 802.11X authentication server

within the LAN. To setup WPA-PSK, you need to input a

passphrase and let the system generate the key. Combination

of letters, numbers and non-alphnumeric charecters is

recommended for ensuring security.

WPA2-PSK:

WPA2 (WI-FI Protected Access 2) provides network

administrators with a high level of assurance that only

authorized users can access the network. Based on the ratified

IEEE 802.11i standard, WPA2 provides government grade

security. The WPA2 can be enabled in two versions -- WPA2-

Personal and WPA2-Enterprise. WPA2-Personal protects

unauthorized network access by utilizing a set-up password.

WPA2-Enterprise verifies network users through a server.

WPA2 is backward compatible with WPA.

Encryption

Encryption is used to convert plain text data into unreadable codes with certain

type of algorithm before capsulation for wireless transmission. WiFi-AP @n

supports the following encryption methods:
WEP:

WEP stands for Wired Equivalent Privacy. It uses 64 or 128-bit

static keys. You can let the system generate the WEP keys by

inputting a Passphrase.

TKIP:

Temporal Key Integrity Protocol (TKIP) dynamically generates

unique keys to encypt every data packet in a wireless session.

AES:

Advanced Encryption Standard (AES) is a dependable

encryption adopted in WPA2 or IEEE802.11i standard. It offers

stronger protection and greatly increases the complexity of

wireless encryption.
