Glossary

AES: A security algorithm; prevents decryption by dividing the security key (password) and by repeatedly performing substitutions and permutations. It is more secure than TKIP.
Channel bandwidth: A bandwidth occupied within a Wi-Fi frequency band. 20 MHz is recommended; 40 MHz (IEEE802.11n/ac) and 80 MHz (IEEE802.11ac) are optionally available for higher data rates.
DHCP function: A function to automatically assign required information (IP address, etc.) to computers, printers or other devices connected to the network.
IEEE802.11a: A wireless networking standard using the 5 GHz band; enables communication at a maximum transfer rate of 54 Mbps.
IEEE802.11ac: Also known as Wi-Fi 5. It is a wireless networking standard using the 5 GHz band; enables communication at a maximum transfer rate of 6.93 Gbps when used with a maximum channel bandwidth of 80 MHz.
Compatible with IEEE802.11n in the 5 GHz band as well as IEEE802.11a.
IEEE802.11b: A wireless networking standard using the 2.4 GHz band; enables communication at a maximum transfer rate of 11 Mbps.
IEEE802.11g: A 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: Also known as Wi-Fi 4. It is a wireless networking standard using the 2.4 GHz band and 5 GHz band; enables communication at a maximum transfer rate of 600 Mbps when used with a maximum channel bandwidth of 40 MHz.
Compatibility with IEEE802.11b/g and IEEE802.11a is achieved in the 2.4 GHz band and in the 5 GHz band, respectively.
IEEE802.1X/EAP (WPA/WPA2/WPA3 Enterprise): A security protocol for wired LAN and Wi-Fi; establishes a network connection based on authentication via user accounts.
IP address: A numerical identification assigned to each computer or network device connected to a network.
IPv4: An Internet protocol to manage IP address.
Normally, IPv4 addresses are automatically assigned to communication devices such as computers connected to a network.
IPv6: An Internet protocol to manage IP address.
Normally, IPv6 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 devices (such as computers) by connecting them to each other. The Internet is a type of network.
Network name (SSID): A name to identify a wireless router used in a wireless 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 broadcast: A wireless router's periodic transmission of a signal revealing its network name (SSID).
Stealth mode: A function to prevent the network name (SSID) of the wireless router from appearing on other Wi-Fi devices.
TKIP: A security protocol; periodic renewal of the security key (password) prevents decryption by a third party.
USB: A standard to connect peripherals (such as printers) to computers and other devices.
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, with improved security compared to WPA.
WPA3: A security protocol for wireless networks. It is a new version of WPA2. High security can be achieved regardless of the length of the security key (password).
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.
