6 Configuration Overview

SSID (SERVICE SET IDENTIFIER)_________

In a wireless network, terminals can be assigned an SSID identifier
which restricts their access to printers on the network to only those
set up for that SSID.

For example, computers set up as Accounting can only
communicate to a printer through the Marketing access point (AP)
and computers set up as Marketing can only communicate to a
printer through the Marketing access point:

SSID = Accounting

SSID = Accounting

SSID = Marketing

SSID = Marketing

CHANNELS_________________________

There are 13 channels available for use in a wireless network.
However, adjacent channels share a frequency and can interfere
with one another.

Therefore, to obtain maximum communication speed and
accuracy, channels for access points which are near each other
should be selected with 5 channels space between them: e.g.,
channels 1, 6 and 11.

7 Configuration Overview

SECURITY FEATURES__________________

Open (no security)

This can be used, but is not recommended.

WEP

Wired Equivalent Privacy, assuring wireless network security
equivalent to a wired network.

Set the same WEP key (64 or 128 bits) for all printers, computers
and access points on the wireless network.

WPA

WiFi Protected Access security, using TKIP encryption. This
security uses a pre-shared key set for all printers, computers and
access points in the wireless network. The key is periodically
changed.

EAP (Using Certificates)

Extensible Authentication Protocol security. In wireless
communications using EAP, connection to the wireless network is
requested through an access point, which in turn transmits the
certificate assigned to the computer and printer to an
authentication server such as RADIUS.

• EAP-TLS is used for authentication.

• Client and/or CA certificates must be imported into the
printer.

• Certificates must be obtained separately by the network
administrator before setting the printer for EAP.

Client Certificates

• This is the printer’s own certificate.

• The client must have a private key which corr esponds to a
public key contained in the certificate.

• Required file format for imported certificates = [PKCS#12].

• Suitable file extensions include *.p12 and *.pfx.

CA Certificates

• The printer is not involved in the CA certificate chain.

8 Configuration Overview

• EAP-TLS requires authentication of the Server Certificate
issued by a Certificate Authority and sent from a RADIUS
server.

• Certificate Authentication requires that the printer have a
certificate issued by the Certificate Authority that issued the
Server Certificate.

• Required file formats = [PEM] or [DER].

• Suitable CA Certificate extensions include *.pem, *.der and
*.cer.

ROUBLESHOOTING

Here is some basic troubleshooting information. For more detailed
information, check out http://my.okidata.com.

PROBLEM SOLUTION(S)

Communication
is unstable.

Communication speed may be decreased or the
wireless connection may be broken due to obstacles
or radio source of 2.4 GHz such as a microwave oven
or cordless phone.

• Check radio sources in the surrounding area.

• Change the location or direction of the access point
and printer.

Too many wireless devices are using the same or
neighboring channel. This can decrease
communication speed or break the wireless
connection.

• Reduce the number of wireless devices using the
same channel.

• Check for access points installed on the floor above
or below and/or for unauthorized access points.

42 Troubleshooting

PROBLEM SOLUTION(S)

Connection
problems for
wireless
devices.

Problems with the access point devices or wireless
computers.

• Consult the FAQ information of the vendors for the
access points and wireless computers.

• Check that you have the latest firmware for access
point devices.

• Check that you have the latest drivers for the
wireless computer.

Access point device may be set to “High-Speed Mode.”

• Disable the High-Speed Mode settings of access
point devices

MAC Address Filtering is enabled in the access point
device.

• Register the wireless card’s MAC address in the MAC
Address FIltering list of the access point device.

Multiple access point devices have the same SSID.

• Check the SSID of access point devices in the
surrounding area.

• Check the SSID of access point devices on the floors
above and below.

• Check for unauthorized access point devices.

43 Troubleshooting

PROBLEM SOLUTION(S)

EAP
authentication
fails.

EAP CA
Certificate

Check the network configuration of the wireless card.

• Make sure that IP Address, Subnet Mask and Default
Gateway are all set correctly.

• Ad-Hoc mode: IP Address cannot be obtained by
DHCP.

Check the network protocol:

• The wireless card supports only TCP/IP protocol.

• Ethernet and IPX/SPX are not supported.

Check the configuration of the wireless card:

• SSID, WEP Key and WPA Pre-Shared Key are all
case sensitive.
