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)
• User access (username: user, password: user)
• Remote (WAN) access (username: support, password: support)
• WLAN 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 ten seconds until the power indicates LED blinking or by clicking the
Restore Default Configuration option in the Restore Settings screen.
13
3.2 IP Configuration
DHCP MODE
When the NexusLink 3112u 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.

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.
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.
14
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.
15
3.3 Login Procedure
Perform the following steps to login to the web user interface.
NOTE: The default settings can be found in section 3.1 Default Settings.

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 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 section 8.6.1 Passwords).

SSID
[1-32
characters]
Sets the wireless network name. SSID stands for Service Set
Identifier. All stations must be configured with the correct SSID to
access the WLAN. If the SSID does not match, that user will not be
granted access.
BSSID
The BSSID is a 48-bit identity used to identify a particular BSS
(Basic Service Set) within an area. In Infrastructure BSS
networks, the BSSID is the MAC (Media Access Control) address of
the AP (Access Point); and in Independent BSS or ad hoc networks,
the BSSID is generated randomly.
Country
A drop-down menu that permits worldwide and specific national
settings. Local regulations limit channel range:

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 configured 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.
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.
62
The settings for WPA-PSK authentication are shown next.
WEP Encryption
This option specifies whether data sent over the network is encrypted. The same
network key is used for data encryption and network authent
ication. Four network
keys can be defined although 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 eavesdropping; in this
case, the capture of wireless network traffic.
When data encryption is enabled, secret shared encryp
tion keys are generated 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 greater number of bits have a greater degree 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
63
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 6.13 for MAC Filter, Wireless Bridge and Advanced Wireless features.
