IP address
A numerical identification assigned to each computer or network device connected to a network.
IPv4
An Internet protocol to manage IP address.
IPv4 addresses are automatically assigned to communication devices such as computers connected to a network.
MAC address
A unique number assigned to each network device.
MAC address filtering
A function to block access from unauthorized devices by saving the MAC addresses.
Network
A system to exchange information between computers by connecting them to each other. The Internet is a type of network.
Port
A socket into which an Ethernet cable or USB cable can be inserted.
Router
A device that plays the role of bridging or connecting the communication between devices (computers, printers, etc.) on the network.
SSID
A name to identify a wireless router used in a wireless network.
SSID broadcast
A wireless router's periodic transmission of a signal revealing its SSID.
Stealth mode
A function to prevent the SSID of the wireless router to appear on other wireless network devices.
TKIP
An encryption standard; periodic encryption key renewal prevents decryption by a third party.
USB
A standard to connect peripherals (printers, etc.) to a computer.
WEP
A security protocol used in IEEE802.11.
WEP key
An encryption key used in WEP.
WEP key number
Select from WEP key 1 to WEP key 4. Select the same WEP key number as the wireless router you want to connect to.
Wi-Fi
A brand name given only to products that have passed Wi-Fi Alliance interoperability tests. Your printer is a Wi-Fi certified product. It may also refer to a LAN (local area network) that does not require cables.
Wired connection
A network that requires an Ethernet cable for connection.
Wireless Direct
A method for connecting the printer to a computer or other devices directly without using a wireless router.
Wireless router
A device that acts as a bridge when establishing a wireless network.
WPA
A security protocol for wireless networks, with improved security compared to WEP.
WPA2
A security protocol for wireless networks. It is a new version of WPA.
WPS
A standard with which wireless device connections and security setting can be established easily. Push button method and PIN code method are available. WPS stands for Wi-Fi Protected Setup.
