Glossary terms

Default gateway
The LAN IP of your router that devices use to reach the internet and the admin panel. Common examples: 192.168.1.1, 192.168.0.1, and 10.0.0.1.
All IP pages Public vs local vs gateway
Private IP / local IP
An address used only inside your home network (e.g. 192.168.x.x or 10.x.x.x). It is not your public internet address.
What is my local IP? What is my IP?
Public IP
The address your ISP assigns to your connection on the internet. Websites see this IP, not your router’s 192.168.x.x address.

SSID
The Wi‑Fi network name broadcast by your router. You can rename it in the admin panel after logging in at the gateway IP.
Admin password vs Wi‑Fi password
The admin password unlocks the router settings page. The Wi‑Fi password lets devices join the wireless network. They are often different — check the sticker for both.

Firmware
The software running on your router. Updates can fix bugs and security issues; always use the manufacturer’s official download when updating.

DNS
Domain Name System translates website names into IP addresses. Your router often hands out DNS to devices; public resolvers like 8.8.8.8 or 1.1.1.1 are not router login pages.

Bridge mode
A modem/gateway setting that disables its router features so another router can handle Wi‑Fi and NAT. In bridge mode, the old gateway admin IP may no longer work as before.
Factory reset
Holding the reset button (usually 10 to 15 seconds) restores factory defaults: default admin password, Wi-Fi name/password, and often the original gateway IP. Custom settings are erased.

WPA2 / WPA3
Wi‑Fi security protocols. Prefer WPA2 or WPA3 for home networks; avoid outdated WEP when possible.
ONT / ISP gateway
Equipment supplied by your internet provider (fibre ONT or cable gateway). Login IPs and passwords are often printed on a label and may differ from retail router defaults.
