4.2.2 Advanced Settings
This page allows advanced users who have sufficient knowledge of wireless LAN. These
setting shall not be changed unless you know exactly what will happen for the changes you
made on your DSL device.

13
Fields in this page:
Field Description
Authentication Type Open System: Open System authentication is not required to be successful while a
client may decline to authenticate with any particular other client.
Shared Key: Shared Key is only available if the WEP option is implemented. Shared
Key authentication supports authentication of clients as either a member of those
who know a shared secret key or a member of those who do not. IEEE 802.11
Shared Key authentication accomplishes this without the need to transmit the secret
key in clear. Requiring the use of the WEP privacy mechanism.
Auto: Auto is the default authentication algorithm. It will change its authentication
type automatically to fulfill client’s requirement.
Fragment Threshold This value should remain at its default setting of 2346. It specifies the maximum size
for a packet before data is fragmented into multiple packets. If you experience a high
packet error rate, you may slightly increases the “Fragment Threshold” value within
the value range of 256 to 2346. Setting this value too low may result in poor network
performance. Only minor modifications of this value are recommended.
RTS Threshold This value should remain at its default setting of 2347. Should you encounter

14
inconsistent data flow, only minor modifications are recommended. If a network
packet is smaller than the preset “RTS threshold” size, the RTS/CTS mechanism will
not be enabled. The ADSL modem (or AP) sends Request to Send (RTS) frames to
a particular receiving station and negotiates the sending of a data frame. After
receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to
acknowledge the right to begin transmission.
Beacon Interval The Beacon Interval value indicates the frequency interval of the beacon. Enter a
value between 20 and 1024. A beacon is a packet broadcast by the ADSL modem
(or AP) to synchronize the wireless network. The default is 100.
Data Rate The rate of data transmission should be set depending on the speed of your wireless
network. You should select from a range of transmission speeds, or you can select
Auto to have the ADSL modem (or AP) automatically use the fastest possible data
rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best
possible connection speed between the AP and a wireless client. The default setting
is Auto.
Preamble Type The Preamble Type defines the length of the CRC (Cyclic Redundancy Check) block
for communication between the AP and mobile wireless stations. Make sure to select
the appropriate preamble type. Note that high network traffic areas should use the
short preamble type. CRC is a common technique for detecting data transmission
errors.
Broadcast SSID If this option is enabled, the device will automatically transmit their network name
(SSID) into open air at regular interval. This feature is intended to allow clients to
dynamically discover and roam between WLANs; if this option is disabled, the device
will hide its SSID. When this is done, the station cannot directly discover its WLAN
and MUST be configure with the SSID. Note that in a home Wi-Fi network, roaming
is largely unnecessary and the SSID broadcast feature serves no useful purpose.
You should disable this feature to improve the security of your WLAN.
Relay Blocking When Relay Blocking is enabled, wireless clients will not be able to directly access
other wireless clients.
Ethernet to Wireless
Blocking
When enabled, traffic between Ethernet and wireless interfaces are not allowed.
Function buttons in this page:
Apply Changes
Change the settings. New parameters will take effect after save into flash memory and

Discard your changes and reload all settings from flash memory.
4.2.3 Security
This screen allows you to setup the wireless security. Turn on WEP or WPA by using
encryption keys could prevent any unauthorized access to your WLAN.
Fields in this page:
Field Description
Encryption There are 4 types of security to be selected. To secure your WLAN, it’s strongly
recommended to enable this feature.
WEP: Make sure that all wireless devices on your network are using the same
encryption level and key. Click Set WEP Key button to set the encryption key.
WPA (TKIP): WPA uses Temporal Key Integrity Protocol (TKIP) for data encryption.
TKIP utilized a stronger encryption method and incorporates Message Integrity Code
(MIC) to provide protection against hackers.
WPA2 (AES): WPA2, also known as 802.11i, uses Advanced Encryption Standard
(AES) for data encryption. AES utilized a symmetric 128-bit block data encryption.
WAP2 Mixed: The AP supports WPA (TKIP) and WPA2 (AES) for data encryption.
The actual selection of the encryption methods will depend on the clients.

16
Use 802.1x
Authentication
Check it to enable 802.1x authentication. This option is selectable only when the
“Encryption” is choose to either None or WEP. If the “Encryption” is WEP, you need
to further select the WEP key length to be either WEP 64bits or WEP 128bits.
WPA Authentication
Mode
There are 2 types of authentication mode for WPA.
WPA-RADIUS: WPA RADIUS uses an external RADIUS server to perform user
authentication. To use WPA RADIUS, enter the IP address of the RADIUS server,
the RADIUS port (default is 1812) and the shared secret from the RADIUS server.
Please refer to “Authentication RADIUS Server” setting below for RADIUS setting.
The WPA algorithm is selected between TKIP and AES, please refer to “WPA cipher
Suite” below.
Pre-Shared Key: Pre-Shared Key authentication is based on a shared secret that is
known only by the parties involved. To use WPA Pre-Shared Key, select key format
and enter a password in the “Pre-Shared Key Format” and “Pre-Shared Key” setting
respectively. Please refer to “Pre-Shared Key Format” and “Pre-Shared Key” setting
below.
Pre-Shared Key
Format
PassPhrase: Select this to enter the Pre-Shared Key secret as user-friendly textual
secret.
Hex (64 characters): Select this to enter the Pre-Shared Key secret as hexadecimal
secret.
Pre-Shared Key Specify the shared secret used by this Pre-Shared Key. If the “Pre-Shared Key
Format” is specified as PassPhrase, then it indicates a passphrase of 8 to 63 bytes
long; or if the “Pre-Shared Key Format” is specified as PassPhrase, then it indicates
a 64-hexadecimal number.
Authentication RADIUS
Server
If the WPA-RADIUS is selected at “WPA Authentication Mode”, the port (default is
1812), IP address and password of external RADIUS server are specified here.

4.2.6 WPS
Although home Wi-Fi networks have become more and more popular, users still have
trouble with the initial set up of network. This obstacle forces users to use the open security
and increases the risk of eavesdropping. Therefore, The Wi-Fi Protected Setup (WPS) is
designed to ease set up of security-enabled Wi-Fi networks and subsequently network
management (Wi-Fi Protected Setup Specification 1.0h.pdf, p. 8).
The largest difference between WPS-enabled devices and legacy devices is that users do
not need the knowledge about SSID, channel and security settings, but they could still surf
in a security-enabled Wi-Fi network.
This device supports Push Button method and PIN method for WPS. The following
sub-paragraphs will describe the function of each item. The webpage is as below.

20
Fields in this page:
Field Description
Disable WPS Check to disable the Wi-Fi protected Setup.
WPS Status When AP’s settings are factory default (out of box), it is set to open security and
un-configured state. “WPS Status” will display it as “UnConfigured”. If it already
shows “Configured”, some registrars such as Vista WCN will not configure AP. Users
will need to go to the “Backup/Restore” page and click “Reset” to reload factory
default settings.
Self-PIN Number “Self-PIN Number” is AP’s PIN. Whenever users want to change AP’s PIN, they
could click “Regenerate PIN” and then click “ Apply Changes”. Moreover, if users
want to make their own PIN, they could enter four-digit PIN without checksum and
then click “ Apply Changes”. However, this would not be recommended since the
registrar side needs to be supported with four-digit PIN.
Push Button
Configuration
Clicking this button will invoke the PBC method of WPS. It is only used when
A
P acts
as a registrar.
Client PIN Number It is only used when users want their station to join AP’s network. The length of PIN
is limited to four or eight numeric digits. If users enter eight-digit PIN with checksum
error, there will be a warning message popping up. If users insist on this PIN, AP will
take it.
