DHCP function: A function to automatically assign required information (IP address, etc.) to computers, printers or other devices connected to the network.
IEEE802.11a: An international wireless networking standard using the 5 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.
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 and supports AES, an encryption standard used in IEEE802.11i.
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.
