14 
4.1 Basic Settings 
Here you can configure the basic wireless settings of the device such as the SSID (name 
of the network) and security. 
 Basic information 
SSID: Select the SSID you wish to use. This is the public name of your wireless network. 
Two SSIDs are supported. 
Enable: Select whether to enable the selected SSID. 
Broadcast SSID: This option allows you to have your network names (SSIDs) publicly 
broadcast or if you choose to disable it, the SSIDs will be hidden. To join your hidden 
wireless network, you must enter the SSID manually. 
AP Isolation: Isolates clients connecting to this SSID. 
Maximum Clients: Set the number of wireless clients that can join your wireless network. 
When the number of wireless clients reaches the set value, new connections to this SSID 
will be denied. 
SSID: This field is configurable. You can change the current SSID.   
Security Mode: Configure  security settings for  the current SSID.  This device supports 
WEP, WPA-PSK, WPA2-PSK, WPA/WPA2-PSK Mixed, WPA and WPA2 (To learn more, 

15 
read the following).   
WEP 
WEP (Wired Equivalent Privacy): WEP is a security algorithm for IEEE 802.11 wireless 
networks. Introduced as part of the original 802.11 standard, its intention was to provide 
data confidentiality comparable to that of a traditional wired network. Wireless speed can 
reach up to 54Mbps if WEP is used. 
Open,  Shared  and  802.1x  are  the  same  in  encryption  progression  yet  different  in 
authentication mode. 
Open: Uses "no authentication" + WEP Encryption. Wireless clients can be associated 
with  the  device  without  going  through  authentication.  Only  data  in  transmission  is 
encrypted with WEP encryption. 
Shared: Uses shared key authentication + WEP Encryption. A WEP key that is mutually 
agreed in advance is required from both sides while wireless clients try to associate with 
the device. Association is established only if the two sides provide the same WEP key. 
802.1x: Adopts802.1x identity authentication + WEP encryption mode. The supplicant (i.e., 
client device) is not allowed to access through the authenticator to the protected side of 

16 
the  network  until  the  supplicant’s  identity  has  been  validated  and  authorized.  If 
authentication is successful, the authenticator sets the port to the "authorized" state and 
normal traffic is allowed, if it is unsuccessful the port remains in the "unauthorized" state 
and blocks traffic. 
Default Key: Specify a WEP key from the preset keys for current use. For example, if you 
select Key 2, wireless clients must join your wireless network using this Key 2. 
 WEP-802.1x Configuration Procedures: 
SSID:  This is  the  public name  of  your  wireless  network. Select  the SSID  you  wish  to 
configure from the drop-down list. 
Security Mode: Select WEP.     
Encryption Mode: Select 802.1X. 
Radius Server: Enter the IP address of Radius server on your LAN. 
Radius Port: Enter the Authentication port for the Radius server on your LAN. 
Radius Key: Enter the Authentication key for the Radius server. 
WPA-PSK, WPA2-PSK 
WPA:  The  WPA  protocol  implements  the  majority  of  the  IEEE  802.11i  standard.  It 
enhances data encryption through the Temporal Key Integrity Protocol (TKIP) which is a 

17 
128-bit per-packet key, meaning that it dynamically generates a new key for each packet. 
WPA also includes a message integrity check feature to prevent data packets from being 
tampered  with.  Only  authorized  network  users  can access  the wireless  network.  WPA 
adopts enhanced encryption algorithm over WEP. 
WPA2: WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead 
of TKIP. It is more secure than WPA and WEP. 
Security Mode: Supports WPA-PSK, WPA2-PSK and WPA/WPA2-PSK Mixed. 
WPA-PSK: Supports AES and TKIP cipher types. 
WPA2-PSK: Supports AES, TKIP and TKIP+AES cipher types. 
WPA/WPA2-PSK mixed: If selected, both WPA-PSK and WPA2-PSK secured wireless 
clients can join your wireless network. 
Cipher Type: Includes AES, TKIP and TKIP&AES. 
AES: If selected, wireless speed can reach up to 300Mbps. 
TKIP: If selected, wireless speed can reach up to 54Mbps. 
TKIP+AES: If selected, both AES and TKIP secured wireless clients can join your wireless 
network. 
Key Update Interval: Enter a valid time period for the key to be changed. 

18 
 Configuration Procedures: 
1) SSID: This is the public name of your wireless network. Select the SSID you wish to 
configure from the drop-down list. 
2) Security Mode: Select WPA-PSK, WPA2-PSK or WPA/WPA2-PSK Mixed. 
3) Cipher Type: Select the cipher type you wish to use. 
4) Key: Enter a security key. 
WPA, WPA2 
The Wi-Fi Alliance defined the WPA/WPA2 in response to weaknesses found in WPA-PSK 
or WPA2-PSK in key management. It uses 802.1x to authenticate users and generate a 
root key for encrypting data instead of using a manually set pre-shared key. 
With  802.1X  authentication,  the  supplicant  provides  credentials,  such  as  user 
name/password or digital certificate, to the authenticator, and the authenticator forwards 
the  credentials  to  the  authentication  server  for  verification.  If the  authentication  server 
determines the credentials are valid, the supplicant (client device) is allowed to access 
resources  located  on  the  protected  side  of  the  network.  Data  transmission  over  the 
wireless network is encrypted with dynamic keys assigned by the Radius server, which 
greatly enhances security. WPA/WPA2 becomes the most preferred security mode with its 
offered better security. 

19 
 Configuration Procedures: 
1) SSID: This is the public name of your wireless network. Select the SSID you wish to 
configure from the drop-down list. 
2) Security Mode: Select WPA or WPA2. 
3) RADIUS Server: Enter the IP address of Radius server on your LAN. 
4) RADIUS Port: Enter the Authentication port for the Radius server on your LAN. 
5) RADIUS Key: Enter the Authentication key for the Radius server. 
6) Cipher Type: Select the cipher type you wish to use.

wireless settings including network mode, channel and etc.     

20 
Enable Wireless: Enable or disable the wireless feature. 
Network Mode: Select a correct mode according to your wireless clients. The default is 
11b/g/n mixed. 
11b: This network mode delivers wireless speed up to 11Mbps and is only compatible with 
11b wireless clients. 
11g: This network mode delivers wireless speed up to 54Mbps and is only compatible with 
11g wireless clients. 
11b/g: This network mode delivers wireless speed up to 54Mbps and is compatible with 
11b and 11g wireless clients. 
11b/g/n  mixed:  This  network  mode  delivers  wireless  speed  up  to  300Mbps  and  is 
compatible with 11b/g/n wireless clients. 
Channel: Select a channel or select Auto to let system automatically select one for your 
wireless network to operate on if you are unsure. The best selection is a channel that is 
the least used by neighboring networks. 
Channel  Bandwidth:  Select  a  proper  channel  bandwidth  to  enhance  wireless 
performance. This option is available only in 802.11b/g/n. Wireless speed in the channel 
bandwidth of 20/40 is 2 times in 20. 

21 
Extension Channel: This is used to ensure N speeds for 802.11n devices on the network. 
This option is available in 11b/g/n mixed mode with channel bandwidth of 20/40. 
WMM-Capable: WMM is QoS for your wireless network. Enabling this option may better 
stream wireless multimedia data (such as video or audio). 
ASPD Capable: Auto power saving mode. This option is effective only if WMM is enabled. 
It is advisable to keep it disabled. 
4.3 Advanced Settings 
Here you can configure the  advanced wireless settings including AP Isolation, Beacon 
interval,  Fragment  threshold,  RTS  threshold  and  DTIM  interval,  etc,  for  your  wireless 
networks. Normally, the default settings will work. If not, change them according to the 
suggestions given by your ISP or our technical staff. Click Wireless -> Advanced to enter 
the configuration interface. 
Note   
Only change the default settings if instructed by your ISP or our technical staff. Wrong 
configurations may degrade your wireless performance. 
Beacon Interval: A time interval between any two consecutive Beacon packets sent by an 
Access  Point  to  synchronize  a  wireless  network.  The  valid  value  range  is  between 

22 
20~999. 
Fragment  Threshold:  Specify  a  Fragment  Threshold  value.  Any  wireless  packet 
exceeding the preset value will be divided into several fragments before transmission. The 
valid value range is between 256~2346. 
RTS Threshold: If a packet exceeds the set value, RTS/CTS scheme will be used  to 
reduce  collisions.  Set  it  to  a  smaller  value  provided  that  there  are  distant  clients  and 
interference. For normal SOHO, it is recommended to keep the default value unchanged; 
otherwise,  device  performance  may  be  degraded.  The  valid  value  range  is  between 
1~2347. 
DTIM  Interval:  A  DTIM  (Delivery  Traffic  Indication  Message)  Interval  is  a  countdown 
informing clients of the next window for listening to broadcast and multicast messages. 
When such packets arrive in the router’s buffer, the router will send DTIM (delivery traffic 
indication message) and DTIM interval to alert clients of the receiving packets. 
Wireless LED: Select to turn on or off the wireless LED. 
Preamble: There are two types of preambles: long preamble and short preamble. The 
preamble signals to the receiving node that data is incoming and indicates when the data 
flow is about to begin. For wireless transmission, the longer the preamble is, the less the 
data is. So support of a short preamble can boost the transmission efficiency of a wireless 
interface. Support of short preamble is optional for 802.11b yet a must for 802.11g.   
4.4 Access Control 
Specify a list of devices to permit or forbid a connection to your wireless network via the 
devices’  MAC Addresses.  Click Wireless -> Access Control to enter the configuration
