Chapter 2: Installation
The Mini AP Router has two basic operating modes that can be set through the web
management interface:
•Router Mode — Normal gateway mode that connects a wired LAN and wireless
clients to an Internet access device, such as a cable or DSL modem. This is the
factory set default mode.
•Bridge Mode — An access point mode that extends a wired LAN to wireless
clients.
In addition to these basic operating modes, each wireless interface supports a
WIreless Distribution System (WDS) link to another Mini AP Router, and a wireless
client mode. These advanced configurations are not described in this section. See
“Network Planning” on page 3-1 for more information.
In a basic configuration, how the Mini AP Router is connected depends on the
operating mode. The following sections describe connections for basic Router Mode
and Bridge Mode operation.
Router Mode
In its default Router Mode, the Mini AP Router forwards traffic between an Internet
connected cable or ADSL modem, and wired or wireless PCs or notebooks. The
basic connections are illustrated in the figure below.

Chapter 3: Network Planning
The Mini AP Router is designed to be very flexible in its deployment options. It can
be used as an Internet gateway for a small network, or as an access point to extend
an existing wired network to support wireless users. It also supports use as a
wireless client to connect to another wireless network, or a wireless bridge to
connect two wired LANs.
This chapter explains some of the basic features of the Mini AP Router and shows
some network topology examples in which the device is implemented.
Internet Gateway Router
The Mini AP Router can connect directly to a cable or DSL modem to provide an
Internet connection for multiple users through a single service provider account.
Users connect to the Mini AP Router either through a wired connection to the LAN
port, or though the device’s own wireless network. The Mini AP Router functions as
an Internet gateway when set to Router Mode.
An Internet gateway employs serveral functions that essentially creates two
separate Internet Protocol (IP) subnetworks; a private internal network with wired
and wireless users and a public external network that connects to the Internet.
Network traffic is forwarded, or routed, between the two subnetworks.
The private local network, connected to the LAN port or wireless interface, provides
a Dynamic Host Configuration Protocol (DHCP) server for allocating IP addresses to
local PCs and wireless clients, and Network Address Translation (NAT) for mapping
the multiple "internal" IP addresses to one "external" IP address.

The public external network, connected to the WAN port, supports DHCP client and
Point-to-Point Protocol over Ethernet (PPPoE) for connection to an Internet service
provider (ISP) through a cable or DSL modem:
LAN Access Point
The Mini AP Router can provide an access point service for an existing wired LAN,
creating a wireless extension to the local network. The Mini AP Router functions as
purely an access point when set to Bridge Mode. When used in this mode, there are
no gateway functions between the WAN port and the LAN and wireless interface.
A Wi-Fi wireless network is defined by its Service Set Identifier (SSID) or network
name. Wireless clients that want to connect to a network must set their SSID to the
same SSID of the network service. The Mini AP Router supports two separate
wireless interfaces, that is two SSIDs or Virtual Access Points (VAPs). The two VAP
interfaces can be configured separately to support different security settings or other
wireless functions.
Wireless Client
The Mini AP Router can operate as a wireless client on one VAP interface, which
enables a connection to another wireless network.
The wireless client option requires the unit to be set to Router Mode. When the
wireless client option is enabled, the client VAP interface functions as the external
gateway interface instead of the WAN port. The other VAP interface, LAN port, and
WAN port all function as the local network within the same IP subnet.

Wireless Bridge
The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge
connections between access points. The Mini AP Router can use WDS to forward
traffic on links between units.
A single WDS bridge link can be specified for each VAP interface. One end of a link
must be configured as the “WDS Parent” and the other as the “WDS Child.” A VAP
interface can be configured as a WDS Parent when the Mini AP Router is set to
either Router Mode or Bridge Mode, but to be configured to WDS child the unit must
be set to Bridge Mode.

Chapter 4: Initial Configuration
The Mini AP Router offers a user-friendly web-based management interface for the
configuration of all the unit’s features. Any PC directly attached to the unit can
access the management interface using a web browser, such as Internet Explorer
(version 6.0 or above).
The initial configuration steps can be made through the web browser interface using
the Setup Wizard. It is recommended to make the initial changes by connecting a
PC directly to the Mini AP Router before installing it in its intended location. The Mini
AP Router has a default IP address of 192.168.1.1 and a subnet mask of
255.255.255.0. If your PC is set to "Obtain an IP address automatically" (that is, set
as a DHCP client), you can connect immediately to the web interface. Otherwise,
you must set your PC IP address to be on the same subnet as the Mini AP Router
(that is, the PC and Mini AP Router addresses must both start 192.168.1.x).
