Preparation
If you intend to use the access point/router to connect your network to the Internet, you
need a broadband Internet connection (DSL or cable). You also need the following
information and equipment:
■A host computer (initially connected to the broadband modem or to a pre-existing
router) that has a network interface card
■An RJ-45 Ethernet cable (Cat-5 or better)
■A DSL or cable modem (purchased or provided by your ISP)
■Host computer’s IP address (assigned by your ISP, if a static IP address is required)
■Subnet mask (assigned by your ISP, if a static IP address is required)
■Default gateway (assigned by your ISP, if a static IP address is required)
■Primary DNS IP address (assigned by your ISP, if a static address is used)
■Host computer’s name and workgroup (available through the Windows Control Panel
under System information)

Preparation
If you intend to use the access point/router to connect your network to the Internet, you
need a broadband Internet connection (DSL or cable). You also need the following
information and equipment:
■A host computer (initially connected to the access point/router) that has a network
interface card
■An RJ-45 Ethernet cable (Cat-5 or better)
■A DSL or cable modem (purchased or provided by your ISP)
■Host computer’s IP address (assigned by your ISP, if a static IP address is required)

■Default gateway (assigned by your ISP, if a static IP address is required)
■Primary DNS IP address (assigned by your ISP, if a static address is used)
■Host computer’s name and workgroup (available through the Windows Control Panel
under System information)
Connectingthehardware
To connect the hardware:
1Turn off and unplug the host computer, the DSL or cable modem, and the access
point/router.
2Using an RJ-45 Ethernet cable (Cat-5 or better), connect the Ethernet port of the host
computer to the LAN 1 connection on the back of the access point/router. You can
also connect as many as three additional computers to the access point/router if you
plan to use the access point/router in wired mode. To connect more than four
computers to your network in wired mode, connect them to a hub or switch, then
connect the hub or switch to one of the LAN ports on the access point/router. This
is not required in wireless mode.
3Using an RJ-45 Ethernet cable (Cat-5 or better), connect the Ethernet port of your
DSL or cable modem to the WAN connection on the back of access point/router.
4Plug the AC adapter into an electrical outlet. Connect the other end of the adapter
to the power connector on the back of the access point/router. For more information,
see the illustration on page 5.

5Turn on the DSL or cable modem. Check the LEDs on the modem to make sure that
the modem is connected and operating normally. The WAN LED on the access
point/router lights when the modem is connected correctly to the access point/router.
6Turn on the host computer. The LAN LED corresponding to the RJ-45 jack used for
the LAN connection on the access point/router lights to when the computer is
connected correctly to the access point/router.
Contactingandconfiguringtheaccess
point/router
Now that all the hardware connections have been made, you must configure the access
point/router to operate on your network and to connect to the Internet through an ISP.
Initial configurations vary somewhat, depending on your ISP. Contact your ISP, before you
configure your access point/router, and determine the following:
■If your ISP assigns a static IP address or provides one automatically (DHCP) each time
you connect to the ISP
■For an automatic IP address, the Host Name (if required) and the Domain Name (if
required)
■For a static IP address, the IP address, subnet mask, default gateway, and DNS address
(at least one)
■If you are connected with a DSL modem using Point-to-Point Protocol over Ethernet
(PPPoE), or if your ISP requires a user name and password, the user name and password
you need to use
■If your ISP uses RAS (Singapore) or PPTP (Europe), instructions for setup
Caution Use only the AC adapterand power cord provided with the
access point/router. Use of any other adapter or power
cord may damage your access point/router and void your
warranty.
Important If you are not comfortable with the procedures covered in
this section, use the Gateway Wireless-G Access
Point/Router Setup Wizard. For more information, see
