Introduction
About Your Network Interface
The EpsonNet 802.11g Wireless Ext. Print Server is a wireless
network interface that connects to the USB port of an Epson device
(such as printer or all-in-one). With this network interface, you
can create a wireless connection between the Epson device and a
local area network using the IEEE 802.11b/g communication
standard.
A radio signal is transmitted over the wireless network when you
send a job to the device. Then the device prints or scans the file
when the network interface receives the radio signal directly from
a computer or from an access point.
This network interface is Wi-Fi certified for interoperability with
other 802.11-compliant products.
Because the network interface supports multiple protocols and
automatically detects protocols on your network, you can print
from Microsoft®Windows®, Apple®Macintosh®, UNIX®, and
IBM®OS/2 applications.
Use EpsonNet EasyInstall to easily configure the network
interface for use on a TCP/IP network. If you are using an
all-in-one, EpsonNet EasyInstall installs the drivers on your
computer. You can use the device on the TCP/IP network at once.
For protocols such as TCP/IP, NetWare, NetBEUI, AppleTalk®,
IPP, and SNMP, you can use EpsonNet Config, the configuration
utility provided with your product, to quickly and easily
configure the network interface to use these protocols.

Note:
The EpsonNet Config utility configures the network interface to work
only with protocols that exist on your network. This does not imply that
you can use all of the above-mentioned protocols on your network or
operating system. The protocols that the network interface can use may
vary depending on the operating system and the network configuration.

Instructions on Using the Network Interface
Notes on powering on and off
❏Do not turn off the device and the network interface when
changing the settings. This may damage the device and the
network interface.
❏Do not turn off the device and the network interface while
printing is in progress. This may cause operational trouble to
the computer sending the print data and suspend the printing
process.
❏Do not turn off the network interface during a firmware
update. Otherwise, the update cannot be completed correctly
and the network interface may not turn on (may not work)
after the update.
Notes on USB connection
❏Only supported devices can connect to a USB downstream
connector of the network interface. Do not use a USB hub.
❏Only IBM compatible computer or Macintosh equipped with
USB can connect to a USB upstream connector of the network
interface.
Notes on security
❏WEP Key
Set a WEP Key or WPA-PSK to prevent wireless interception
by unauthorized persons. The wireless transmission speed is
reduced when WEP or WPA-PSK is enabled because time is
required for encryption and decryption.

❏Security lock
Insert a commercially available theft-prevention cable
through the security lock, which is located on the back panel
of the network interface, to secure the device to a table or
pillar. This network interface is compatible with the
Microsaver Security System manufactured by Kensington.
Notes on radio waves
❏Radio wave interference may occur when there are devices
that use radio waves within the 2.4 GHz ISM band near the
network interface. Therefore, separate the network interface
from these devices as much as possible to prevent radio wave
interference.
❏When using the network interface in the Ad Hoc mode, radio
wave interference may occur if the channel of the network
interface and the other devices are close to each other.
Therefore, separate a few channels from the channel used near
the network interface.
❏Shorten the distance of the network interface and devices that
communicate with the network interface.
Where to locate the network interface
❏The location of the network interface must be considered to
improve the wireless communication. The rotary stand can
provide a good position. The condition of radio wave can be
checked using EpsonNet Config, lights of the network
interface, and the status sheet.

Status sheet button
The first time you use the network interface after installing or
reinstalling it, plug the power cord of the network interface into
a wall outlet while holding down the status sheet button for about
twenty seconds to initialize the network interface. The length of
time necessary to hold down the status sheet button varies
depending on the device model.
Before you start configuring the network interface, be sure to
press and hold down the status sheet button on the network
interface to print a status sheet. A status sheet provides important
information about the network interface, such as MAC address,
SSID, device settings, and device’s current status. Press the status
sheet button once to print a simple status sheet, or twice to print
a full status sheet. You cannot print a status sheet when the device
has already started printing, or when it is offline or not ready to
print.
Note:
If the device does not print a status sheet, make sure the device is online
and no print jobs are being processed, then wait a minute. If it still does
not print a status sheet, turn the device off, wait until the DATA light
goes out while the red USB light is on, and then turn it back on again.
The status sheet can be printed one minute after the device finishes
warming up.
cCaution:
After turning off the device, wait until the DATA light goes out
before turning it back on; otherwise the network interface may not
work correctly.

An IEEE 802.11b/g WLAN (wireless local area network) operates
within the 2.4 GHz ISM band. It divides the 2.4 GHz into 11 or 13
channels using Direct-Sequence Spread Spectrum (DSSS), and
uses Carrier Sense Multiple Access with Collision Avoidance
(CSMA/CA) to avoid packet collision. Both CSMA/CA with
ACK and CSMA/CA with RTS/CTS are supported.
Wi-Fi certification
This wireless network interface is
Wi-Fi certified by the Wi-Fi Alliance
(WFA). The WFA certification ensures
full product interoperability with
other Wi-Fi certified products. For

In the Infrastructure mode, both wireless and wired computers
can communicate through an access point to send data to the
network interface.
Note:
Some access points or routers support only the TCP/IP protocol. If you
use this product with a protocol other than TCP/IP, make sure the
protocols are supported by the access point or router.
In the Ad Hoc mode, a network interface and computers
wirelessly communicate directly with each other, without using
an access point.

Security
WEP (Wired Equivalent Privacy) is a security protocol for
wireless network. Data is encrypted using the WEP Key
providing the security of your wireless network. You must set the
same WEP Key to the network interface and the access point.
The network interface supports a 64-bit or 128-bit encryption key,
and you can use either hexadecimal or ASCII characters.
WPA-PSK(TKIP) is a Wi-Fi security with a strong encryption
algorithm as well as user authentication. It provides a high
security that user data remains protected and that only authorized
users may access the network.
Note:
The wireless transmission speed is reduced when WEP or
WPA-PSK(TKIP) is enabled because time is required for encryption and
decryption.
SSID is a unique identifier to specify a wireless LAN. All devices
and access points connected to a specific wireless LAN must use
the same SSID to communicate with devices on the wireless LAN.
Radio signal range
The data transfer rate of the network interface depends on the
environment where the network interface is located.
Note:
The wireless transmission speed decreases as the distance between the
network interface and the computer or the access point increases.
