Introduction
The D-Link DSA-3100 Airspot Gateway is a simple-to-use network access control
system supporting Ethernet, Fast Ethernet or an IEEE 802.11 wireless LAN (WLAN)
separately and simultaneously.
TheDSA-3100canbeconfigured withastandardHTMLbrowser(i.e.,InternetExplorer,
Netscape Navigator) operating on Windows 98SE/Me/2000/XP, Macintosh OS 9, Mac
OS X (v10.1.5 or later), Linux, or Pocket PC 2000/2002. The DSA-3100 allows the
operator to offer wired or wireless networking services and access to the Internet
when used with a switch or wireless access point respectively. The device features
many management settings allowing for private and public access to the Internet and
the necessary privilege mechanisms to permit this usage.

Installation
Standard 10/100Base-T network (UTP/Cat5 Ethernet) cable
with RJ45 connectors.
TCP/IP network protocol must be installed on all networked
computers and related devices.
Requirements

11
Setting up the DSA-3100
Make sure the DSA-3100 unit is not connected to the power
adapter and is powered OFF.
WAN port connection
Use 10/100BaseT connections to connect the unmanaged network.
The unmanaged network’s interface may be the ADSL router’s LAN
port, cable modem’s LAN port or Intranet switch port.
Private LAN port connection
Use to connect to a local network. All ports are auto-mdix, which means
that you can use a straight-through or a crossover cable for connections.
Public LAN port connection
Use to connect to a switch or an access point for Hotspot access. All ports
are auto-mdix, which means that you can use a straight-through or a
crossover cable for connections.
Power ON
Connect the supplied power adapter to the DSA-3100 and insert the
plug on the other end into an electric outlet.
Check the LEDs
The power LED and WAN LED should be ON, if the
corresponding WAN port is connected to an active cable/DSL
modem or T1 line.
The corresponding local network or authentication indicator should
be ON if a network device is connected to the private network port or
the public network port.

If your PC uses the default Windows XP/2000/Me/98SE setting, no
changes need to be made. Just restart your PC.
If you are running Mac OS 9 or OS X, set your network settings to
DHCP and select Apply.
DSA-3100 will act as a DHCP Server, automatically providing a
suitable IP address (and related information) to each computer
when the computer reboots or when the network settings refresh.
For all non-Server versions of Windows, the default TCP/IP setting
is to act as a DHCP client. In Windows, the setting for this is Obtain an
IP address automatically.
If you are using a fixed IP address on your LAN, or if you want to check
your TCP/IP setting, refer to the Networking Basics section in
this manual.
Configure PCs on your LAN

the LAN from those devices outside the network.
NAT:
In this mode, the DSA-3100 will not protect the
identity of the connected devices by translating their
IP addresses and shielding them from detection
outside the LAN.

All devices, regardless of their IP address, can gain
access to the Internet through the DSA-3100 in this
mode.
