an idle timeout, the light will remain green 
if an ADSL connection is still present.
Off Modem power off, modem in bridged mode 
or ADSL connection not present.    In 
addition, if an IP or PPPoE session is 
dropped for any reason, other than an idle 
timeout, the light is turned off.
Blink IP connected and IP Traffic is passing 
through the device (either direction)

 10
Note: 
A malfunction is any error of internal sequence or state that will prevent the device 
from connecting to the DSLAM or passing customer data. This may be identified at 
various times such after power on or during operation through the use of self testing 
or in operations which result in a unit state that is not expected or should not occur. 
IP connected (the device has a WAN IP address from IPCP or DHCP and DSL is up or 
a static IP address is configured, PPP negotiation has successfully complete – if 
used – and DSL is up ) and no traffic detected. If the IP or PPPoE session is dropped 
for any other reason, the light is turned off. The light will turn red when it attempts 
to reconnect and DHCP or PPPoE fails. 
WiFi/WPS Button 
Press and release WiFi-WPS button to activate WPS (make sure the WPS is enabled 
in Wireless->Security page). 
Press and hold WiFi-WPS button more than 5 seconds to enable/disable WiFi. 

 11
Chapter 3 Web User Interface 
This section describes how to access the device via the web user interface (WUI) 
using an Internet browser such as Internet Explorer (version 5.0 and later).     
3.1 Default Settings 
The factory default settings of this device are summarized below. 
•  LAN IP address: 192.168.1.1 
•  LAN subnet mask: 255.255.255.0 
•  Administrative access (username: root , password: 12345 ) 
•  WIFI access: enabled 
Technical Note 
During power on, the device initializes all settings to default values.  It will then 
read the configuration profile from the permanent storage section of flash memory.   
The default attributes are overwritten when identical attributes with different values 
are configured.    The configuration profile in permanent storage can be created via 
the web user interface or telnet user interface, or other management protocols.  
The factory default configuration can be restored either by pushing the reset button 
for more than five seconds until the power indicates LED blinking or by clicking the 
Restore Default Configuration option in the Restore Settings screen. 
3.2 IP Configuration 
DHCP MODE 
When the AR-5312u powers up, the onboard DHCP server will switch on. Basically, 
the DHCP server issues and reserves IP addresses for LAN devices, such as your PC. 
To obtain an IP address from the DCHP server, follow the steps provided below.     
NOTE:  The following procedure assumes you are running Windows XP.   
However, the general steps involved are similar for most operating 
systems (OS). Check your OS support documentation for further details. 
STEP 1:   From the Network Connections window, open Local Area Connection (You 
may also access this screen by double-clicking the Local Area Connection 
icon on your taskbar). Click the Properties button. 
STEP 2:  Select Internet Protocol (TCP/IP) and click the Properties button.  
STEP 3:  Select Obtain an IP address automatically as shown below. 

 12
STEP 4:   Click OK to submit these settings. 
If you experience difficulty with DHCP mode, you can try static IP mode instead. 

 13
STATIC IP MODE 
In static IP mode, you assign IP settings to your PC manually. 
Follow these steps to configure your PC IP address to use subnet 192.168.1.x. 
NOTE:  The following procedure assumes you are running Windows XP.   
However, the general steps involved are similar for most operating 
systems (OS). Check your OS support documentation for further details. 
STEP 1:  From the Network Connections window, open Local Area Connection (You 
may also access this screen by double-clicking the Local Area Connection 
icon on your taskbar). Click the Properties button. 
STEP 2:  Select Internet Protocol (TCP/IP) and click the Properties button. 
STEP 3:  Change the IP address to the 192.168.1.x (1<x<255) subnet with subnet 
mask of 255.255.255.0. The screen should now display as shown below. 
STEP 4:   Click OK to submit these settings. 

 14
3.3 Login Procedure 
Perform the following steps to login to the web user interface.     
NOTE:  The default settings can be found in 3.1 Default Settings. 
STEP 1:   Start the Internet browser and enter the default IP address for the device 
in the Web address field. For example, if the default IP address is 
192.168.1.1, type http://192.168.1.1. 
NOTE:  For local administration (i.e. LAN access), the PC running the browser 
must be attached to the Ethernet, and not necessarily to the device.     
For remote access (i.e. WAN), use the IP address shown on the Chapter 4 
Device Information screen and login with remote username and 
password. 
STEP 2:   A dialog box will appear, such as the one below.    Enter the default 
username and password, as defined in section 3.1 Default Settings. 
 Click OK to continue. 
NOTE:    The login password can be changed later (see 8.6.1 Passwords). 

 15

5.4.2 Security 
The following screen appears when Wireless Security is selected. The options shown 
here allow you to configure security features of the wireless LAN interface. 
Click Apply/Save to implement new configuration settings. 
WIRELESS SECURITY 
Setup requires that the user configure these settings using the Web User Interface 
(see the table below). 
Select SSID 
Select the wireless network name from the drop-down box. SSID stands for Service 
Set Identifier.    All stations must be confi
g
ured with the correct SSID to access the 
WLAN. If the SSID does not match, that client will not be granted access. 
Network Authentication 
This option specifies whether a network key is used for authentication to the 
wireless network.    If network authentication is set to Open, then no authentication 
is provided.    Despite this, the identity of the client is still verified.     

 58
Each authentication type has its own settings.    For example, selecting 802.1X 
authentication will reveal the RADIUS Server IP address, Port and Key fields.    WEP 
Encryption will also be enabled as shown below. 
The settings for WPA authentication are shown below. 
The settings for WPA-PSK authentication are shown next. 

 59
WEP Encryption 
This option specifies whether data sent over the network is encrypted. The same 
network key is used for data encryption and network authentication. Four network 
keys can be defined althou
g
h only one can be used at any one time. Use the Current 
Network Key list box to select the appropriate network key.   
Security options include authentication and encryption services based on the wired 
equivalent privacy (WEP) algorithm.    WEP is a set of security services used to 
protect 802.11 networks from unauthorized access, such as eavesdroppin
g
; in this 
case, the capture of wireless network traffic.     
When data encryption is enabled, secret shared encryption keys are 
g
enerated and 
used by the source station and the destination station to alter frame bits, thus 
avoiding disclosure to eavesdroppers. 
Under shared key authentication, each wireless station is assumed to have received 
a secret shared key over a secure channel that is independent from the 802.11 
wireless network communications channel. 
Encryption Strength 
This drop-down list box will display when WEP Encryption is enabled.    The key 
strength is proportional to the number of binary bits comprising the key.    This 
means that keys with a 
g
reater number of bits have a 
g
reater de
g
ree of security and 
are considerably more difficult to crack.    Encryption strength can be set to either 
64-bit or 128-bit.    A 64-bit key is equivalent to 5 ASCII characters or 10 
hexadecimal numbers.    A 128-bit key contains 13 ASCII characters or 26 
hexadecimal numbers.    Each key contains a 24-bit header (an initiation vector) 
which enables parallel decoding of multiple streams of encrypted data. 
Please see section 6.12 for MAC Filter, Wireless Bridge and Advanced Wireless 
features.

Auto Detection notice 
Note: The following description concerning ETHWAN is for multiple LAN port devices 
only.ġ
1) This feature will automatically detect one WAN service only. If customers require 
multiple WAN services, manual configuration is required. 
2) If a physical ETHWAN port is detected, the Auto Detection for ETHWAN will be 
fixed on the physical ETHWAN port and cannot be configured for any LAN port; 
if the physical ETHWAN port is not detected, the Auto Detection for ETHWAN will 
be configured to the 4
th
 LAN port by default and allows it to be configured for any 
LAN port as well. 
3) For cases in which both the DSL port and ETHWAN port are plugged in at the 
same time, the DSL WAN will have priority over ETHWAN. For example, the 
ETHWAN port is plugged in with a WAN service detected automatically and then 
the DSL port is plugged in and linked up. The Auto Detection feature will clear

 74
6.2.2 MAC Filtering 
NOTE:  This option is only available in bridge mode. Other modes use IP Filtering 
to perform a similar function. 
Each network device has a unique 48-bit MAC address. This can be used to filter 
(block or forward) packets based on the originating device. MAC filtering policy and 
rules for the AR-5312u can be set according to the following procedure.   
The MAC Filtering Global Policy is defined as follows. FORWARDED means that all 
MAC layer frames will be FORWARDED except those matching the MAC filter rules.   
BLOCKED means that all MAC layer frames will be BLOCKED except those 
matching the MAC filter rules. The default MAC Filtering Global policy is 
FORWARDED. It can be changed by clicking the Change Policy button. 
Choose Add or Remove to configure MAC filtering rules. The following screen will 
appear when you click Add. Create a filter to identify the MAC layer frames by 
specifying at least one condition below. If multiple conditions are specified, all of 
them must be met. Click Save/Apply to save and activate the filter rule. 

 75
Click Save/Apply to save and activate the filter rule. 
Consult the table below for detailed field descriptions. 
Field  Description 
Protocol Type  PPPoE, IPv4, IPv6, AppleTalk, IPX, NetBEUI, IGMP 
Destination MAC Address Defines the destination MAC address 
Source MAC Address  Defines the source MAC address 
Frame Direction  Select the incoming/outgoing packet interface 
WAN Interfaces  Applies the filter to the selected bridge interface 

 76
6.3 Quality of Service (QoS)

 (See Appendix E - Connection Setup for detailed PVC setup instructions).
To Enable QoS tick the checkbox and select a Default DSCP Mark.     
Click Apply/Save to activate QoS. 
QoS and DSCP Mark are defined as follows: 
Quality of Service (QoS): This provides different priority to different users or data 
flows, or guarantees a certain level of performance to a data flow in accordance with 
requests from Queue Prioritization. 
Default Differentiated Services Code Point (DSCP) Mark: This specifies the per hop 
behavior for a given flow of packets in the Internet Protocol (IP) header that do not 
match any other QoS rule. 

 77
6.3.1  QoS Queue Setup 
Configure queues with different priorities to be used for QoS setup. 
In ATM mode, maximum 16 queues can be configured. 
In PTM mode, maximum 8 queues can be configured. 
For each Ethernet interface, maximum 3 queues can be configured. 
To add a queue, click the Add button. 
To remove queues, check their remove-checkboxes (for user created queues), then 
click the Remove button. 
The Enable button will scan through every queues in the table. Queues with 
enable-checkbox checked will be enabled. Queues with enable-checkbox 
un-checked will be disabled. 
The enable-checkbox also shows status of the queue after page reload. 

 78
Note that if WMM function is disabled in Wireless Page, queues related to wireless 
will not take effect. This function follows the Differentiated Services rule of IP QoS. 
You can create a new Queue entry by clicking the Add button.   
Enable and assign an interface and precedence on the next screen. Click 
Save/Reboot on this screen to activate it. 
Click Add to display the following screen. 
Click Apply/Save to apply and save the settings. 
Name: Identifier for this Queue entry. 
Enable: Enable/Disable the Queue entry. 
Interface: Assign the entry to a specific network interface (QoS enabled). 

 79
6.3.2 QoS Policer 
To remove policers, check their remove-checkboxes, then click the Remove button. 
The Enable button will scan through every policers in the table. Policers with 
enable-checkbox checked will be enabled. Policers with enable-checkbox 
un-checked will be disabled. 
The enable-checkbox also shows status of the policer after page reload. 
To add a policer, click the Add button. 
Click Apply/Save to save the policer. 

 80
Field  Description 
Name  Name of this policer rule

6.3.3  QoS Classification 
The network traffic classes are listed in the following table. 
Click Add to configure a network traffic class rule and Enable to activate it. To 
delete an entry from the list, click Remove. 
This screen creates a traffic class rule to classify the upstream traffic, assign 
queuing priority and optionally overwrite the IP header DSCP byte. A rule consists of 
a class name and at least one logical condition. All the conditions specified in the 
rule must be satisfied for it to take effect. 
Click Apply/Save to save and activate the rule. 

 82
Field  Description 
Traffic Class Name  Enter a name for the traffic class. 
Rule Order  Last is the only option.

Classification Criteria 
Class Interface Select an interface (i.e. Local, eth0-4, wl0) 
Ether Type  Set the Ethernet type (e.g. IP, ARP, IPv6). 
Source MAC Address  A packet belongs to SET-1, if a binary-AND of its source 
MAC address with the Source MAC Mask is equal to the 
binary-AND of the Source MAC Mask and this field. 
Source MAC Mask  This is the mask used to decide how many bits are checked 
in Source MAC Address. 
Destination MAC 
Address 
A packet belongs to SET-1 then the result that the 
Destination MAC Address of its header binary-AND to the 
Destination MAC Mask must equal to the result that this 
field binary-AND to the Destination MAC Mask. 
Destination MAC Mask This is the mask used to decide how many bits are checked 
in Destination MAC Address. 
Classification Results 
Specify Class Queue  Packets classified into a queue that exit through an 
interface for which the queue is not specified to exist, will 
instead egress to the default queue on the interface. 
Specify Class Policer  Packets classified into a policer will be marked based on 
the conforming action of the policer 
Mark Differentiated 
Service Code Point   
The selected Code Point gives the corresponding priority to 
packets that satisfy the rule. 
Mark 802.1p Priority  Select between 0-7.   
Set Rate Limit  The data transmission rate limit in kbps.
