How to Change the Wi-Fi Password on a Router

Securing Your Home Network

When your internet service provider first installs your broadband router, they usually configure it with a factory-default Wi-Fi password printed on a sticker underneath the physical box. While convenient for the technician, keeping this default password is a terrible idea for your long-term security.

Default passwords are often surprisingly easy for automated hacking tools to guess based on the router’s brand. Furthermore, over the years, you will inevitably give your Wi-Fi password to house guests, neighbours, and perhaps even smart home technicians. Because a password cannot be “un-shared,” the only way to kick unwanted devices off your network and regain control of your bandwidth is to change the Wi-Fi password entirely.

To change your Wi-Fi password, you must log directly into the administrative control panel built into the router itself.

Step 1: Find Your Router’s IP Address

Your router hosts a tiny, hidden website that acts as its control panel. To access it, you need to type its specific IP address into your web browser.

• On Windows: Click the Start Menu, type cmd, and press Enter to open the Command Prompt. Type ipconfig and press Enter. Look for the line that says Default Gateway. The series of numbers next to it (usually something like 192.168.1.1 or 192.168.0.1) is your router’s address.
• On a Mac: Click the Apple Logo > System Settings > Network > Wi-Fi. Click the “Details” button next to your active connection. Look for the number listed next to Router.

Step 2: Log Into the Router Control Panel

Now that you have the address, you need to access the dashboard.

1. Open your web browser (Chrome, Safari, Edge, etc.).
2. Type the IP address directly into the top address bar (e.g., type exactly 192.168.1.1) and press Enter.
3. A login screen will appear demanding an admin username and password.

Crucial Note: This login is not your Wi-Fi password. This is the master administrator password for the router hardware itself. If you have never changed this, look at the sticker on the back of the physical router box. It will usually list the “Admin Password” or “Router Password” (common default usernames are often just “admin,” and the password might be “admin,” “password,” or blank).

Step 3: Change the Wi-Fi Password

Because every router brand (Netgear, TP-Link, Asus, Linksys) uses completely different dashboard software, the exact menus will look different depending on your equipment. However, the terminology is universally similar.

1. Once logged in, look for a menu labelled Wireless, WLAN, Wi-Fi, or Network Settings.
2. Look for a sub-menu named Wireless Security or WLAN Security.
3. You will see a text box containing your current Wi-Fi password. It is usually labelled Pre-Shared Key, WPA Key, Passphrase, or simply Password.
4. Delete the old password and type in your new one. Ensure it is at least 12 characters long and uses a mix of letters and numbers for adequate security.
5. Optional but recommended: Ensure the Security Type dropdown menu above the password box is set to WPA2-PSK or WPA3 (never use the outdated WEP option, as it is dangerously insecure).
6. Click Save or Apply at the bottom of the screen.

Step 4: Reconnect All Your Devices

The moment you click Save, the router will reboot its wireless antennas to apply the new security key.

This means every single wireless device in your home—your phone, your laptop, your smart TV, and your smart thermostat—will instantly be kicked off the internet. You will need to go to each device, open its Wi-Fi settings, select your network name, and type in the new password to get it back online.
