You need your router's address to change the Wi-Fi password, forward a port, or work out why the internet has stopped. It takes about fifteen seconds once you know where to look, and the instructions differ slightly on every platform.
The address you want is your default gateway: the machine your device sends traffic to when the destination is not on the local network. On a home network, that is the router.
Open Command Prompt or PowerShell and run:
ipconfigFind the adapter you are actually using — "Wi-Fi" or "Ethernet" — and read the Default Gateway line. Ignore adapters showing no address; those are disconnected or virtual.
For a shorter answer:
ipconfig | findstr /i "Default Gateway"In Terminal:
route -n get default | grep gatewayOr through the interface: System Settings, Network, select your connection, Details, then the TCP/IP tab. The router is listed there.
On anything current:
ip route | grep defaultThe output begins default via 192.168.1.1, and that address is your router. On older systems route -n gives the same information, with the gateway on the line whose destination is 0.0.0.0.
Settings, then Wi-Fi, then tap the small circled i beside the network you are connected to. Scroll to the IPv4 section and read Router.
The path varies by manufacturer, which is a recurring theme with Android. Generally: Settings, Network & internet, Wi-Fi, tap the connected network, then look for Advanced, Gateway, or Router.
Some versions simply do not display it. If yours is one of them, the address is almost certainly the common default for your router — and if the usual guesses fail, connecting from a laptop for one minute is faster than hunting through menus.
If you cannot check, these cover most home equipment:
192.168.1.1 — the most common by a wide margin192.168.0.1 — the next most common10.0.0.1 — common on cable equipment and some ISP-supplied routers192.168.1.254 or 192.168.0.254 — common on UK and European DSL equipment172.16.0.1 — occasional, usually business equipmentType one into a browser with http:// in front. If a login page appears, that is your router.
You get a search results page. The browser treated the address as a search term. Type the full form with http:// at the front.
The page times out. You are probably on the wrong network — a guest Wi-Fi, or a VPN capturing all traffic. Disconnect the VPN and confirm you are on your own network.
The gateway address is not your router. On a network with a separate modem and router, or a mesh system, the gateway may be an intermediate device. Follow the chain: log into what you find, and look for the address it uses as its gateway.
The gateway starts with 100.64. That range is reserved for carrier-grade NAT, meaning your provider is sharing one public address across many customers. Your router has no public address of its own, and no amount of port forwarding will make inbound connections work.
Two things are worth doing on any router you have just logged into for the first time.
Change the admin password if it is still the default. Router default credentials are published in searchable lists, and malware that reconfigures home routers to use hostile DNS servers is common, persistent, and invisible from the affected devices.
Check for a firmware update. Home routers are a standing target precisely because so few people ever update them, and manufacturers do sometimes fix real vulnerabilities.
Is my router's IP address the same as my public IP address?
No, and this is the most common confusion here. The router has a private address on your network, typically 192.168.something, and a separate public address facing the internet. The private one is what you use to log in, and the IP lookup tool shows you the public one.
Why do I see two gateway addresses?
One is IPv4 and the other IPv6. Either usually works for the admin interface; the IPv4 one is easier to type.
Can I change my router's address?
Yes, in its own LAN settings. Only do so if you have a reason — every device gets a new address afterwards, and anything with a hardcoded reference to the old one stops working.
I have forgotten the router password.
A physical reset button, held for around ten seconds, restores factory defaults. It also wipes your Wi-Fi name, password and every other setting, so treat it as a last resort and expect to reconfigure everything.
