The fastest way to change your password

Open a web browser on any device connected to your WiFi and type your router's IP address into the address bar. For most home routers, this is 192.168.1.1 or 192.168.0.1. You will see a login screen asking for a username and password — these are different from your WiFi password and are printed on a sticker on the back or bottom of your router.

Once you log in, look for a section called Wireless, WiFi, Security, or Network. The exact name depends on your router brand. Find the field labeled Password, Passphrase, or Pre-Shared Key, delete the old password, type your new one, and click Save or explore. Your router will restart — this takes 30 seconds to two minutes, and your WiFi will drop briefly.

Key Takeaways

  • You log into your router using the username and password on the sticker attached to it, not your WiFi password.
  • The router's login page is reached by typing 192.168.1.1 or 192.168.0.1 into a web browser address bar.
  • After you save a new password, your router restarts and all devices lose connection for one to two minutes.
  • You will need to reconnect each device to WiFi using the new password once the router comes back online.

Finding your router's login address if the standard ones do not work

If 192.168.1.1 and 192.168.0.1 do not load a login page, your router uses a different address. On Windows, open Command Prompt and type ipconfig, then look for the line that says Default Gateway — that number is your router's address. On Mac, open System Preferences, click Network, select your WiFi connection, and click Advanced — the router address is listed under TCP/IP.

Another option is to check the router's manual or the manufacturer's website. You can also look at the sticker on the back of the router — many newer models print the login address there alongside the username and password.

What to do if you forgot the router's admin password

If you cannot remember the username and password printed on the sticker, you will need to reset the router to factory settings. On the back of the router, there is a small recessed button labeled Reset. Use a paperclip or pen to hold it down for 10 to 15 seconds while the router is powered on. The lights will blink and the router will restart.

After the reset, the username and password return to the factory defaults printed on the sticker. This erases your WiFi password and all other settings, so you will need to set up the router again from the beginning. If you do not have the sticker, visit the router manufacturer's website and search for your model number — the default credentials are listed there.

Reconnecting your devices after the password changes

Once your router restarts and the lights stop blinking, your devices will no longer be connected to WiFi. On your phone, tablet, or computer, open the WiFi settings, find your network name in the list, and select it. When prompted, enter your new password exactly as you typed it — passwords are case-sensitive, so uppercase and lowercase letters matter.

If a device says the password is wrong even though you typed it correctly, forget the network and try again. On iPhone and iPad, go to Settings > WiFi, tap the info icon next to your network, and tap Forget This Network. On Android, long-press the network name and select Forget. On Windows, go to Settings > Network & Internet > WiFi > Manage Known Networks, select your network, and click Forget.

Choosing a strong password you will actually remember

A strong WiFi password is at least 12 characters long and mixes uppercase letters, lowercase letters, numbers, and symbols. Avoid using your name, address, or birthdate. A phrase you will remember — like "BlueCat#Sleeps2024" — is stronger than a random string you will forget and have to reset again.

Write the new password down and store it somewhere safe, like a notebook in a drawer or a password manager on your phone. This way you have it when a guest asks for the WiFi password or when you need to reconnect a device months later.

Why your WiFi drops when you change the password

When you save a new password in the router settings, the router restarts to explore the change. During this restart, the radio that broadcasts your WiFi signal turns off and back on. Any device connected to that signal loses its connection and must reconnect using the new password.

This is normal and expected. The restart usually takes one to two minutes. If your router does not come back online after five minutes, unplug it for 30 seconds and plug it back in. If it still does not work, check that you saved the password correctly by logging back into the router settings and looking at what password is actually stored there.

Changing the password on a mesh WiFi system

Mesh systems like Eero, Netgear Orbi, or TP-Link Deco work differently than single routers. Instead of logging into an IP address, you use a mobile app to manage the network. Open the app, go to Settings or WiFi Settings, find the password field, and change it there. The system will restart all nodes, which takes two to three minutes.

If you do not have the app installed, read it from the App Store or Google Play and log in using the email address you used when you first set up the system. If you forgot that email or password, you can reset the entire mesh system by holding down the reset button on the main node for 10 to 15 seconds, then set it up again from scratch using the app.

Frequently Asked Questions

Do I need to change my WiFi password regularly?

There is no set rule, but changing it once or twice a year is reasonable if you want to prevent old guests or neighbors from connecting. If you suspect someone has your password, change it when ready. If your network has never been compromised and you trust everyone who knows the password, changing it less often is fine.

What if I change the password and one device will not reconnect?

Forget the network on that device and reconnect from scratch. Make sure you are typing the password exactly as you set it — spaces and capital letters count. If it still fails, restart the device and try again. If one device consistently fails while others work, that device may have a WiFi hardware problem.

Can I change my WiFi password from my phone?

Yes, if you use a mesh system with a mobile app — you can change the password directly in the app. For a traditional router, you can open a web browser on your phone, type the router's IP address, and log in the same way you would on a computer. The steps are identical.

Will changing my password disconnect my smart home devices?

Yes, all devices will lose connection when the router restarts. You will need to reconnect each smart device using the new password. Some devices like smart speakers have a dedicated app that walks you through reconnecting; others require you to go into WiFi settings on the device itself.

What if I set a password and now I cannot remember it?

Reset the router to factory settings using the reset button, which erases the password and returns it to the default. You will need to set up the router again and choose a new password. Write it down this time so you have it for future reference.
