2.3 Preparing for Configuration
For the user (or administrator) to configure an advanced AP, a managing computer with a Web browser is
needed. For first-time configuration of an advanced AP, an Ethernet network interface card (NIC) should
have been installed in the managing computer. For maintenance-configuration of a deployed advanced
AP, either a wireless computer or a wired computer can be employed as the managing computer.
NOTE: If you are using the browser, Opera, to configure an advanced AP, click the menu item File, click
Preferences..., click File types, and edit the MIME type, text/html, to add a file extension ".sht" so that
Opera can work properly with the Web management pages of the advanced AP.
Since the configuration/management protocol is HTTP-based, we have to make sure that the IP address
of the managing computer and the IP address of the managed advanced AP are in the same IP
subnet (the default IP address of an AP is 192.168.0.1 and the default subnet mask is 255.255.255.0.)
NOTE: The AP’s factory default setting is to obtain its IP address automatically from a DHCP Server.
When the AP restarts it attempts to obtain an IP address repeatedly for approximately 75 seconds. If this
fails then it adopts the default IP address of 192.168.0.1.
2.3.1 Connecting the Managing Computer and the Advanced AP
To connect the Ethernet managing computer and the managed AP for first-time configuration, the user
has two choices as illustrated in Fig. 2.

The user can use either a cross-over Ethernet cable (we have included one in the package) or a switch/hub
with 2 normal Ethernet cables.
NOTE: One connector of the Ethernet cable must be plugged into the LAN/Config Ethernet socket of the
advanced AP for configuration.
2.3.2 Changing the TCP/IP Settings of the Managing Computer
Use the Windows Network Control Panel Applet to change the TCP/IP settings of the managing
computer, so that the IP address of the computer and the IP address of the advanced AP are in the same IP
subnet. Set the IP address of the computer to 192.168.0.xxx (the default IP address of an AP is
192.168.0.1) and the subnet mask to 255.255.255.0.
NOTE: For some versions of Windows, the computer needs to be restarted for the changes of TCP/IP
settings to take effect.
