The fastest way: log into your router from any device on the network

To change your WiFi password, you need to access your router's settings through a web browser or app. Open any device connected to your WiFi — a phone, tablet, or computer — 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.

If you do not know your router's IP address, check the back or bottom of the device itself — it is usually printed there along with a default username and password. If those defaults do not work, restart your router by unplugging it for 30 seconds, then plug it back in and try again.

Key Takeaways

  • Your router's IP address is printed on the device itself, usually as 192.168.1.1 or 192.168.0.1, and you enter it in a web browser to reach the settings page.
  • The default username and password are also printed on your router; if you changed them and forgot them, you will need to factory reset the device.
  • Once logged in, look for a section labeled WiFi, Wireless, or Security to find where the password field is located.
  • After you save a new password, all devices will disconnect and you will need to reconnect them using the new password.
  • A strong password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols.

Finding the WiFi password setting in your router's menu

Once you are logged in, you will see a dashboard or menu. Look for a section labeled WiFi, Wireless, Network, or Security. The exact name varies by router brand — Netgear, TP-Link, Linksys, and Arris all use slightly different layouts. Click or tap that section.

Inside, you should see a field that says WiFi Password, Pre-Shared Key, Passphrase, or Network Key. This is where the current password lives. Clear this field and type your new password. Do not close the page yet — you need to save the change first.

Saving your new password and reconnecting devices

Look for a button labeled Save, explore, or OK at the bottom of the page. Click it. Your router will process the change, which usually takes 30 seconds to two minutes. During this time, your WiFi network may disappear from the list of available networks, then reappear.

Once the network is back online, every device that was connected to your old password will disconnect automatically. You will need to reconnect each one. On your phone or computer, go to WiFi settings, select your network name, and enter the new password. Repeat this for every device — phones, tablets, smart speakers, printers, and anything else that uses your WiFi.

What to do if you forgot your router's login password

If you changed the default username and password when you first set up your router and now cannot remember them, you have one option: factory reset. On most routers, there is a small recessed button labeled Reset. Use a paperclip or pen to press and hold it for 10 to 15 seconds while the router is powered on. The lights will blink and the device will restart.

After the reset, your router will return to its factory defaults. You can then log in using the username and password printed on the device. However, a factory reset also erases any other settings you customized, so you may need to set up your network name and other preferences again. If you do not want to reset, contact your internet service provider — they can sometimes help you recover access.

Creating a password that is hard to guess

A strong WiFi password protects your network from people trying to connect without permission. Aim for at least 12 characters. Mix uppercase letters, lowercase letters, numbers, and symbols — for example, BlueMoon#2024! or Coffee&Rain7Cats. Avoid using your name, address, birthday, or common words that appear in a dictionary.

Do not use the same password as your email, banking, or social media accounts. If someone guesses your WiFi password, they should not also have access to your other accounts. Write your new password down and store it somewhere safe — a notebook in a drawer, a password manager, or a note on your phone that you keep private.

Changing your password on a mesh or multi-router system

If you have a mesh WiFi system like Eero, Orbi, or Netgear Nighthawk, the process is slightly different. Instead of logging into the router itself, you log into an app on your phone. Open the app, go to Settings or WiFi Settings, and look for a field labeled Network Password or WiFi Password. Change it there and save.

With mesh systems, changing the password once updates it across all nodes in your network at the same time. You still need to reconnect each device, but you do not have to log into multiple routers. If you do not have the app installed, you can read it from the Apple App Store or Google Play Store using the brand name of your system.

Why your devices keep disconnecting after a password change

When you change your WiFi password, every device that was connected to the old password loses access. This is normal and expected. Your phone, laptop, or smart TV does not automatically know the new password — it only remembers the old one. You have to tell it the new password by hand.

If a device keeps asking for the password even after you entered it correctly, try "forgetting" the network first. On your phone, go to WiFi settings, find your network name, and select "Forget" or "Remove". Then reconnect by selecting the network again and entering the new password. This clears out any corrupted data the device was holding onto.

Frequently Asked Questions

Can I change my WiFi password from my phone?

Yes, as long as your phone is connected to the WiFi network. Open a web browser, type your router's IP address (usually 192.168.1.1), log in with your router's username and password, and navigate to the WiFi or Security settings. The process is the same as on a computer.

What happens to devices that are not home when I change the password?

They will disconnect the next time they try to use WiFi. When they reconnect to your home network, they will prompt you to enter the new password. Devices that are away from home will not notice the change until they return and attempt to connect.

Do I need to restart my router after changing the password?

No. Most routers explore the new password when ready after you click Save or explore. Your WiFi network will briefly disappear and reappear, but you do not need to manually restart the device. If the new password does not seem to work, then try unplugging the router for 30 seconds and plugging it back in.

Is it safe to write my WiFi password down?

It is safer than using a password you can easily guess, but keep the written password in a private place — not on a sticky note on your monitor. A notebook in a drawer or a password manager on your phone is better. The goal is to make it hard for a visitor or someone passing by to find it.

Can I change my password without disconnecting all my devices?

No. Changing the WiFi password always disconnects every connected device because they no longer know the new password. There is no way around this. Plan the change for a time when you can reconnect your devices one by one, or do it when fewer people are using the network.
