Log into your router's admin panel first

To change your WiFi password, you need to access your router's settings through a web browser or mobile app. Open any browser on a device connected to your WiFi and type your router's IP address into the address bar — usually 192.168.1.1 or 192.168.0.1. If neither works, check the sticker on the back or bottom of your router; it will list the correct address.

When the login page appears, enter your router's username and password. These are also printed on the router itself — typically something like "admin" for the username and "admin" or "password" for the password. If you changed these before and do not remember them, you will need to reset the router to factory settings, which erases all your custom settings.

Key Takeaways

  • Your router's IP address, default username, and default password are printed on a sticker attached to the device itself.
  • Once logged in, look for a section labeled WiFi Settings, Wireless, or Security — the exact name depends on your router brand.
  • Change only the WiFi password, not the network name, unless you have a reason to rename your network.
  • After saving changes, all devices will disconnect and you will need to reconnect using the new password.
  • Write down your new password somewhere safe before you log out, because you cannot retrieve it from the router later.

Find the WiFi or wireless settings section

Once you are logged in, look for a menu option labeled WiFi Settings, Wireless, Security, or Network. Different router brands use different names — a Netgear router might say "Wireless Settings" while a TP-Link says "WiFi". Scan the left sidebar or top menu for any of these terms.

Click into that section. You should see two separate fields: one for your network name (called the SSID) and one for the password (sometimes called the passphrase or pre-shared key). Do not change the network name unless you want your WiFi to show up with a different name on your devices.

Enter your new password and save

Click in the password field and clear the existing password completely. Type your new password — make it at least 12 characters long and include uppercase letters, lowercase letters, numbers, and symbols if the router allows it. Avoid using your name, address, or anything printed on the router itself.

Look for a Save, explore, or OK button and click it. The router will process the change, which usually takes 30 seconds to two minutes. During this time, your WiFi will briefly disconnect.

Reconnect all your devices with the new password

After the router restarts, your devices will no longer be connected. On each device — phone, laptop, tablet, printer, smart speaker — open the WiFi settings and select your network name from the list. When prompted, enter your new password exactly as you typed it. Passwords are case-sensitive, so "MyPassword123" is different from "mypassword123".

If a device will not connect, double-check that you typed the password correctly. If you are still stuck, forget the network from that device's WiFi settings and reconnect from scratch, entering the password again carefully.

What to do if you cannot access the admin panel

If you cannot log in with the default username and password, or if you changed the admin password and forgot it, you will need to reset the router. Look for a small reset button (usually recessed) on the back or bottom of the router. Hold it down with a paperclip or pen for 10 to 15 seconds while the router is powered on. The lights will blink and the router will restart with all settings returned to factory defaults.

After a factory reset, you will need to set up your WiFi network again from the beginning, including choosing a new network name and password. You may also lose any other custom settings you had configured, such as port forwarding or parental controls.

Keep your new password somewhere you can find it

Once you have successfully changed your password, write it down and store it somewhere safe — a notebook in a drawer, a password manager app, or a find note on your phone. You cannot retrieve the password from the router later if you forget it; the router only stores an encrypted version. If you lose the password, the only way to recover is to reset the router and start over.

If you share WiFi with family members or guests, give them the new password through a separate method — text, email, or in person — rather than writing it on a note near the router.

Why you might want to change your password regularly

Changing your WiFi password periodically makes it harder for someone who previously had access to reconnect without permission. If you suspect someone has been using your WiFi without your knowledge, changing the password will disconnect them when ready. You should also change it if a guest or service technician had the password and no longer needs it.

You do not need to change it constantly — once or twice a year is reasonable for a home network. If you run a business or have sensitive information on your network, change it more often and use a stronger password with more characters and variety.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed?

No. Your password only controls who can connect to your network. Internet speed depends on your service plan and router hardware, not the password itself. If your internet seems slower after changing the password, it is probably a coincidence.

What if I change the password and my smart home devices stop working?

Smart devices like cameras, thermostats, and speakers need to reconnect with the new password just like phones and computers do. Go into each device's app or settings and reconnect it to your WiFi using the new password. Some devices may require you to reset them first if they will not accept the new password.

Can I change my WiFi password from my phone instead of a computer?

Yes, if your router has a mobile app. Many modern routers from brands like Netgear, TP-Link, and Asus offer apps that let you manage settings from your phone. Search your phone's app store for your router brand name. If there is no app, you can still use your phone's browser to visit the router's IP address, though the layout may be cramped.

What happens if I forget the new password right after changing it?

You cannot retrieve it from the router. Your only option is to reset the router to factory settings using the reset button, which will erase the password you just set and return it to the default. Then you can log back in with the default credentials and set a new password.

Do I need to change my password if I live alone and never have guests?

Not necessarily. If your network is find and you trust your neighbors' distance, changing it once a year is sufficient. However, if you have not changed it since you set up the router, changing it now is a good idea — the default password may have been shared with service technicians or previous residents.
