Router and Wi-Fi Glossary

WAN is the connection toward your ISP. LAN is your local network. A default gateway routes local traffic onward. NAT translates addresses. CGNAT is carrier-level address translation. Backhaul connects mesh nodes. AP mode broadcasts Wi-Fi while another router handles routing. Firmware is device software; hardware revision identifies a physical variant.
