4.1.1
Wireless Network Setup Wizard
This wizard provides a step -by-step guide to create and secure a new access point on
the router. The network name (SSID) is the AP identifier that will be detected by
supported clients. The Wizard uses a TKIP+AES cipher for WPA / WPA2 security;
depending on support on the client side, devices associate with this AP using either
WPA or WPA2 security with the same pre -shared key.
The wizard has the option to automatically generate a network key for the AP. This
key is the pre-shared key for WPA or WPA2 type security. Supported clients that
have been given this PSK can associate with this AP. The default (auto-assigned)
PSK is “passphrase”.
The last step in the Wizard is to click the Connect button, which confirms the
settings and enables this AP to bro adcast its availability in the LAN.
4.1.2
Add Wireless Device with WPS
With WPS enabled on your router, the selected access point allows supported WPS
clients to join the network very easily. When the Auto option for connecting a

wireless device is chose, you will be presented with two common WPS setup
options:
Personal Identification Number (PIN):
The wireless device that supports
WPS may have an alphanumeric PIN, and if entered in this field the AP will
establish a link to the client. Click Connect to complete setup and connect to
the client.
Push Button Configuration (PBC):
for wireless devices that support PBC,
press and hold down on this button and within 2 minutes , click the PBC
connect button. The AP will detect the wireless device and establish a link
to the client.
You need to enable at least one AP with WPA/WPA2 security and also enable WPS
in the
Advanced > Wireless Settings > WPS
page to use the WPS wizard.
4.1.3
Manual Wireless Network Setup
This button on the Wizard page will link to the
Setup> Wireless Settings> Access
Points
page. The manual options allow you to create new APs or modify the
parameters of APs created by the Wizard.
4.2 Wireless Profiles
Setup > Wireless Settings > Profiles
The profile allows you to assign the security type, encryption and authentication to
use when connecting the AP to a wireless client. The default mode is “open”, i.e. no
security. This mode is insecure as it allows any compatible wireless clients to connect
to an AP configured with this security profile.
To create a new profile, use a unique profile name to identify the combination of
settings. Configure a unique SSID that will be the identifier used by the clients to
communicate to the AP using this profile. By choosing to broadcast the SSID,
compatible wireless clients
within range of the AP can detect this profile’s
availability.
The AP offers all advanced 802.11 security modes, including WEP, WPA, WPA2 and
WPA+WPA2 options. The security of the Access point is configured by the Wireless
Security Type section:
Open: se
lect this option to create a public “open” network to allow unauthenticated
devices to access this wireless gateway.
WEP (Wired Equivalent Privacy): this option requires a static (pre -shared) key to
be shared between the AP and wireless client . Note that W EP does not support
802.11n data rates; is it appropriate for legacy 802.11 connections.

WPA (Wi-Fi Protected Access): For stronger wireless security than WEP, choose
this option. The encryption for WPA will use TKIP and also CCMP if required. The
authentication can be a pre-shared key (PSK), Enterprise mode with RADIUS
server, or both. Note that WPA does not support 802.11n data rates; is it
appropriate for legacy 802.11 connections.
WPA2: this security type uses CCMP encryption (and the option to add TKIP
encryption) on either PSK (pre-shared key) or Enterprise (RADIUS Server)
authentication.
WPA + WPA2: this uses both encryption algorithms, TKIP and CCMP. WPA
clients will use TKIP and WPA2 clients will use CCMP encryption algorithms.
“WPA+WPA2” is a security option that allows devices to connect to an AP using
the strongest security that it supports. This mode allows legacy devices that only
support WPA2 keys (such as an older wireless printer) to connect to a secure AP
where all the other wireless clients are using WPA2.

4.2.1 WEP Security
If WEP is the chosen security option, you must set a unique static key to be shared
with clients that wish to access this secured wireless network. This static key can be
generated from an easy-to-remember passphrase and the selected encryption length.
Authentication: select between Open System, or Shared Key schemes

Encryption: select the encryption key size -- 64 bit WEP or 128 bit WEP.
The larger size keys provide stronger encryption, thus making the key more
difficult to crack
WEP Passphrase: enter an alphanumeric phrase and click Generate Key to
generate 4 unique WEP keys with length determined by the encryption key
size. Next choose one of the keys to be used for authentication. The selected
key must be shared with wireless clients to connect to this d evice.

4.2.2
WPA or WPA2 with PSK
A pre-shared key (PSK) is a known passphrase configured on the AP and client both
and is used to authenticate the wireless client. An acceptable passphrase is between
8 to 63 characters in length.
4.2.3 RADIUS Authentication
Advanced > RADIUS Settings
Enterprise Mode uses a RADIUS Server for WPA and/or WPA2 security. A
RADIUS server must be configured and accessible by the router to authenticate
