Wireless Network Install Guide_ 

•

Check whether the machine is within the range of the wireless network.

•

Check whether the machine is located away from obstacles that could block the wireless 

signal. Remove any large metal objects between the access point (or wireless router) 

and the machine. Make sure the machine and wireless access point (or wireless router) 

are not separated by poles, walls, or support columns containing metal or concrete.

•

Check whether the machine is located away from other electronic devices that may 

interfere with the wireless signal. Many devices can interfere with the wireless signal, 

including a microwave oven and some Bluetooth devices.

IEEE 802.11 authentication is a process of identifying an individual who is attempting to 

access a wireless LAN or an Access Point. The IEEE 802.11 standard defines two types 

of authentication services:

-

Open System: Authentication is not used, and encryption may or may not be used, 

depending on the need for data security.

-

Shared Key: Authentication is used. A device that has the proper WEP key can 

access the network. Samsung Network Printer supports both authentication 

methods.

WEP (Wired Equivalent Privacy) is a security protocol preventing an unauthorized 

access to your wireless network suggested by IEEE 802.11 standard. Wireless LANs, 

which are over radio waves, do not have the physical structure that can be protected 

from unauthorized access and therefore are vulnerable to tampering.
WEP is designed to provide a wireless LAN with a security level equal to what is found 

on a wired network. WEP encrypts the data portion of each packet exchanged on the 

wireless network using a 64-bit or 128-bit WEP encryption key. Sometimes 64-bit WEP 

is called 40-bit and 128-bit is 104-bit. Both 40-bit and 64-bit encryption are really the 

same, as are 104-bit and 128-bit encryption, because an additional 24 initialization 

vector (IV) bits are automatically added for a total of 64 bit and 128 bits. To encrypt data, 

Samsung Network Printer uses four encryption keys.
You should select a key and enter the key value. The key value must be the same as the 

other wireless devices or the access point of your wireless network. In 64-bit mode, each 

key value is 10 hexadecimal digits (0-9 and A-F) or 5 alphanumeric characters. In 128-bit 

mode, each key value is 26 hexadecimal digits or 13 alphanumeric characters. Contact 

with your network administrator for this configuration.

WPA announced by Wi-Fi Alliance uses WPA(WPA2)-Enterprise(802.1x) or 

WPA(WPA2)-Personal(WPA-PSK) for authentication. WPA(WPA2)-Personal authorizes and 

identifies users based on a secret key between wireless user (station) and wireless supplier 

(access point). WPA uses TKIP (Temporal Key Integrity Protocol) and AES (Advanced 

Encryption Standard) for data encryption.
