DHCP function
  A function to automatically assign required information (IP address, etc.) to computers, printers or other devices connected to the network.
Direct Connection
  A method for connecting the printer to a computer or other devices directly without using a wireless router.
IEEE802.11a
  An international wireless networking standard using the 5.2 GHz band; enables communication at a maximum transfer rate of 54 Mbps.
IEEE802.11ac
  An international wireless networking standard using the 5 GHz band; enables communication at a maximum transfer rate of 6.93 Gbps.
  A successor standard to IEEE802.11n.
IEEE802.11b
  An international wireless networking standard using the 2.4 GHz band; enables communication at a maximum transfer rate of 11 Mbps.
IEEE802.11g
  An international wireless networking standard using the 2.4 GHz band; enables communication at a maximum transfer rate of 54 Mbps.
  Compatible with IEEE802.11b.
IEEE802.11n
  An international wireless networking standard using the 2.4 GHz band and 5 GHz band; enables communication at a maximum transfer rate of 600 Mbps.
  Compatibility with IEEE802.11b/g is achieved in the 2.4 GHz band.
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.
WCN
  A function to configure wireless connection settings easily only by entering the PIN code. (WCN-NET) WCN stands for Windows Connect Now.
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 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.
