Type the router address from the label on the router — often 192.168.1.1 or 192.168.0.1 — into your browser, sign in with the admin details on that label, open the Wi-Fi (WLAN) settings, choose WPA2 or WPA3, enter a new password and save.
Find your router’s address
Look under or behind the router: the label usually lists the address, the admin username and password, and the current Wi-Fi name and password. The most common addresses are 192.168.1.1, 192.168.0.1, 192.168.1.254 and 10.0.0.1. On Android you can also open Settings → Wi-Fi, tap your network and look for “Gateway” or “Router”. Some providers manage the router through their own app or website instead.
Change it
- Connected to your Wi-Fi, type the address into the browser’s address bar.
- Sign in with the admin details from the label. If they were changed and you don’t know them, ask whoever set up the router, or your provider.
- Open Wi-Fi, WLAN or Wireless → Security.
- Choose WPA2-Personal or WPA3-Personal and type the new password. If there are separate 2.4 GHz and 5 GHz networks, change both.
- Save, reconnect your phone with the new password, then update your other devices.
Need a strong password?
A long random password beats a clever one. This one is made of 16 letters and numbers in groups of four, so it’s still easy to type on a TV remote. It’s created on your device and never sent anywhere.

16 random letters and numbers in groups of four — strong, and easy to type on a TV remote. Avoid letters that look alike (l, 1, o, 0).

Leave these alone
Don’t change the Internet/WAN settings (PPPoE, VLAN, connection type) unless you know exactly what they do — that’s the fastest way to lose your connection. The reset button restores factory settings and erases your provider’s configuration, so keep it as a last resort. And while you’re signed in, change the router’s admin password too, if it lets you.
After the change, a quick check with Diagnostix360 confirms your phone still reaches the router and the internet normally.
Frequently asked questions
What is 192.168.1.1?+
A common local address for router settings pages. It only works on your own network, and your router may use another one — the label will say.
I forgot the router admin password. What now?+
Check the label first. If it was changed, ask whoever set it up or your provider. A factory reset brings back the label password but also erases your provider’s settings.
WPA2 or WPA3?+
WPA3 is newer and stronger. If older devices can’t connect, choose WPA2/WPA3 mixed mode or WPA2.
Check everything still works
Once the new password is in, Diagnostix360 can confirm in about a minute that your phone reaches the router, the internet and DNS normally.
