Wireless basic settings
These are the basic parameters required to make wireless
connections found on the
Wireless
page of SyncThru Web
Service. Click
Apply
after changing parameters.
•
SSID
: SSID (Service Set Identifier) is a name that identifies
a wireless network. Access points and wireless devices
attempting to connect to a specific wireless network must
use the same SSID. The SSID is case-sensitive.
•
Operation Mode
: Operation Mode refers to the type of
wireless connections. Choose one of the following options:
-
Ad hoc
: allows wireless devices to communicate directly
with each other in a peer-to-peer environment.
-
Infrastructure
: allows wireless devices to communicate
with each other through an access point.
•
Frequency Mode
: Choose a frequency mode. The Samsung
print server supports 802.11a, 802.11b, and 802.11g
frequency modes.
-
802.11a (5GHz) mode
: Data is sent using IEEE802.11a
standard communications in the 5 GHz band.
-
802.11b/g (2.4GHz) mode
: Data is sent using
IEEE802.11g standard communications in the 2.4 GHz
band. This mode is compatible with IEEE802.11b standard.
-
802.11a, b/g (5GHz, 2.4GHz) mode
: Data is sent using
the frequency range defined in both IEEE802.11a and
IEEE802.11g standards.
•
Ad hoc Channel
: Change the channel selection setting. If
you select
Auto Setting
, the Samsung print server will
automatically adjust channels. To manually set a channel,
select
Channel Selection
. In most cases, manually setting
up channels is not required.
•
Connection Status
: This section displays information on the
current wireless connection.
-
Link Status
: indicates whether or not the WLAN interface
is connected to other wireless devices.
-
Associated Frequency
: indicates the associated frequency
mode, for example, 802.11a.
-
BSSID
: displays the associated BSSID, for example,
00:02:78:E3:43:89.
-
Link Quality
: represents quality of the wireless link
between the print server and an access point or other
devices by percentage, for example, 100%
-
Current Tx Rate
: is automatically determined by radio
transmission speed, for example, 54 Mbps.
-
Current Channel
: represents the associated channel, for
example, [149] 5745 MHz.
NOTE
: Your wireless basic setting changes will be applied after
the print server restarts. In order to restart the print server,
from SyncThru Web Service, select
Network Settings
Æ
Reset
and click
Restart
, or turn the print server off and then
back on.
Wireless security settings
This section describes how to configure wireless security for
your wireless network. The Samsung Network Printer Card
supports several security features, such as static WEP, IEEE
802.1x, and WPA, to protect your network from unauthorised
access, and provides three security modes:
•
None
: This is used when the validation of a wireless device's
identity and data encryption are not required for your
network. Open system is used for IEEE 802.11
authentication.
•
Static WEP
: This uses the WEP (Wired Equivalent Privacy)
algorithm suggested by IEEE 802.11 standard for security.
Static WEP security mode requires a proper WEP key for
data encryption, decryption, and IEEE 802.11
authentication.
•
Enhanced Security
: This provides more advanced security
and better key management than Static WEP by using IEEE
802.1x EAP authentication, WPA-PSK, and dynamic
encryption, such as dynamic WEP, TKIP, and AES. In
Enhanced Security mode, there are four authentications,
depending on WPA authentication and 802.1x
authentication:
-
WPA-PSK authentication
: You can select WPA-PSK to
authenticate the print server based on WPA Pre-Shared
Key. This uses a shared secret key (generally called Pre-
Shared Key passphrase) that is manually configured on the
access point and each of its clients. This is suitable for
users who want to use WPA but do not have a RADIUS
server installed on their network.
-
EAP-TLS authentication
: EAP-TLS uses X.509-compliant
digital certificates for both client and network server
authentications. Root certificates and client certificates
must be installed on the print server.
-
EAP-TTLS authentication
: EAP-TTLS uses an X.509-
compliant digital certificate for network server
authentication. This also requires a 802.1x user name,
user password, and a TTLS identity used by inner
authentication protocols for client authentication over a
secure connection.
-
PEAP authentication
: PEAP is similar to EAP-TTLS. This
also uses an X.509-compliant digital certificate for network
server authentication and requires an 802.1x user name
and user password used by inner authentication protocols
for client authentication over a secure connection.
Additionally, you may configure the related parameters to use
a special security mode. The following table summarises the
security modes and authentication options available on the
Samsung network print server and describes the features of
each option:
