1 Connect the Hardware
1Use an Ethernet cable to connect the Ethernet port (opposite the power socket) on the
included MS-POE-IJ power injector (Ain the figure) to the NWA3550’s Ethernet port.
2Use an Ethernet cable to connect the other Ethernet port (next to the power socket) to
a computer for initial configuration.
3Connect the power injector to a proper power source using the included power cord.
The NWA3550 receives it's power from the power injector using PoE (Power over
Ethernet).
4After you have completed the initial configuration, connect the Ethernet port (next to the
power socket) of the power injector to an Ethernet jack with network access (for
example, a broadband modem or router).
1.1 Power Injector Light
• The LED (light) on the power injector shines green steadily when the power is connected.
VIf the LED does not turn on, check your connections and inspect the cables
for damage. If the LED is still off, contact your vendor.

ENGLISH

2 Access the Web Configurator
"Use Internet Explorer 6.0 and later or Netscape Navigator 7.0 and later
versions with JavaScript enabled and pop-up blocking disabled.
2.1 Set Up Your Computer’s IP Address
"Note down your computer’s current IP settings before you change them.
First, set your computer to use a static IP address in the 192.168.1.3 - 192.168.1.254
range with a subnet mask of 255.255.255.0. This ensures that your computer can
communicate with your NWA3550. See your User’s Guide for information on setting up
your computer’s IP address.
2.2 Log Into the Web Configurator
"Even though you can connect to the NWA3550 wirelessly, it is
recommended that you connect your computer to the Ethernet port for
initial configuration.
1Launch your web browser. Enter
192.168.1.2 (the NWA3550’s default
IP address) as the address.
VIf you cannot access the Web configurator, make sure the IP addresses
and subnet masks of the NWA3550 and the computer are in the same IP
address range (see Section 2.1).

ENGLISH

2Click Login (the default password
1234 is already entered).
3Change the login password by
entering a new password and
clicking Apply. Be sure to record the
new password and keep it in a safe
place.
VIf you change the password and then forget it, you will need to reset the
NWA3550. Contact your vendor.
4Click Apply to replace the factory
default certificate for added security;
alternatively click Ignore to proceed
if you do not want to change the
certificate now.

ENGLISH

3.2 Configure Wireless Settings
1Click WIRELESS in the
navigation panel. The
following screen
appears.
"The wireless stations and the NWA3550 must use the same SSID,
channel ID and encryption settings for wireless communication.
WLAN Interface: Ensure that WLAN1 is selected.
Operating Mode: Ensure that Access Point mode is selected.
802.11 Mode: Select the wireless standard you want your network to use. If you are not
sure which to select, select 802.11b+g.
Choose Channel ID: Select the wireless channel you want your network to use. To have
the NWA3550 automatically select a channel, click Scan instead.
SSID Profile: Select the SSID profile you want to configure for network access from the
drop-down list box. This example uses the SSID03 profile.
2Click Apply to save your settings.

ENGLISH
9
3Click the SSID tab. The
following screen appears.
Ensure the settings for
SSID03 are at their default
values.
The default SSID (the name
of the network) is ZyXEL03,
its default Security setting is
Security01.Layer 2
Isolation and MAC Filter
are set to Disable by default.
If you want to change the
SSID profile’s settings,
select SSID03 and click
Edit.
4Click the Security tab.
Ensure that Security01 is
selected and click Edit.
If you don’t configure
wireless security, anyone
can access your network.

ENGLISH

5This is where you can enter
the security settings for
your wireless network. The
fields you fill in differ
according to the type of
security you select in the
Security Mode field. Select
None if you do not wish to
use wireless security.
This example uses WPA2-
PSK security, in which all
wireless clients must use the
same pre-shared key to join
the network.
Ensure that all your wireless
clients support the type of
security you set. Click Apply
when you have finished.
VIf the wireless clients cannot communicate with the network, ensure that
the clients and the NWA3550 are using the same wireless security
settings.

ENGLISH

3.3 Configure IP Settings
The NWA3550 is now ready to connect to your switch or router. You can do this now, or
once you have attached the antennas and mounted the NWA3550.
1You need to set your
NWA3550’s IP address to be
in the same subnet as your
network. Click IP in the
navigation panel.
Select Get automatically from
DHCP if you want to have a
DHCP server on your network
assign an IP address to the
NWA3550.
If you have a specific IP address
to use, select Use fixed IP
address and enter it along with
the subnet mask and gateway
IP address.
Click Apply. The NWA3550 now
uses the new IP settings; you
can no longer connect to the
NWA3550 using the default IP
address.
"If you change the NWA3550’s IP address, you must use the new IP
address when you next access the web configurator. If you select Get
automatically from DHCP, check your DHCP server to determine the IP
address it assigns to the NWA3550. Refer to your DHCP server’s
documentation for more information.
2If you changed your computer’s IP address in Section 2.1, return it to its previous
setting.
3Change the wireless settings in the wireless stations to match those of the NWA3550.
Refer to your wireless adapter’s documentation.

ENGLISH
12
VIf the NWA3550 cannot communicate with the network, ensure that the
NWA3550 is using an IP address on the same subnet as the switch / router.
4 Install the Hardware
Complete the following procedures to install the NWA3550 on a pole or wall.
4.1 Hardware Mounting
In general, the best location for the access point is at the center of your intended wireless
coverage area. For better performance, mount the NWA3550 high up in an area that is free
of obstructions.

orientation.
4.1.4 Wall-mounting
1Select a position free of obstructions on a sturdy wall.
2Position the wall/pole bracket on the wall to mark how far apart the screws should be
placed. Drill four holes for the masonry plugs.
"Be careful to avoid damaging pipes or cables located inside the wall when
drilling holes for the screws.
3Insert the masonry plugs into the wall.
"The included screws and masonry plugs are intended primarily for use with
concrete walls. You may need to use different screws and plugs, depending
on your wall's material.

5Install four wall mounting screws through the holes on
the wall/pole bracket into the plugs to secure the
mounting bracket to the wall. Make sure the screws are
snugly and securely fastened to the wall.
6Adjust the NWA3550, cables and antennas for correct
orientation.
4.2 Attaching Antennas
Screw the antennas clockwise onto the antenna connectors on the bottom of your
NWA3550.
