How to change the Wi-Fi password?

With the democratization of the internet, more and more users have access to stable broadband connections, either via cable or by Wi-Fi signal. This new form of communication has also raised discussions about privacy and digital security, as well as protecting themselves from possible hacker attacks – or simply preventing unwanted connections from neighbors.

In the case of Wi-Fi routers, it is possible to set a password to limit access to the connection provided by the equipment. This process is very simple and can be done in a few steps using a computer or even a cell phone, depending on the brand of the router you own.

In this sense, TecMundo has prepared a guide to assist the user in each step of the process. Check out:

How to change your Wi-Fi password on your computer

Obtaining the default IP address of the router

First of all, it is necessary to obtain the default IP of the router to gain access to all its functions, as well as its password. On the Windows operating system, this can be easily done using the CMD (also known as Command Prompt).

To get started, just search for “CMD ” on the Windows Start bar or via the Run shortcut, accessed quickly by the “Windows key + R” and then typing “CMD.exe”.

Then, type “ipconfig” (without the quotes) and press the “Enter” key. The default IP address of the router can be found by the number corresponding to the term Default Gateway. Typically, the most common standard IP addresses are “” and “” for Windows systems or “” for Apple systems, but may vary depending on the make and model of the router.

Changing the router password

Now, to access the router’s settings, simply copy and paste the default IP address into a preferred web browser. Then, a website or pop-up will be displayed, requiring input information to access the equipment’s tools.

By default, both the username and password are usually “admin” (again, without the quotes). However, if these credentials do not work, the data set by the manufacturer can be found on the label on the back of the router.

After accessing the router settings interface, the process becomes more intuitive. To illustrate an example, the Archer C50 from TP-Link will be used, however, the steps also apply to other models and brands.

Then, for the router in question, the user must select the Wi-Fi network that he wants to change the password, being “Wireless 2.4 GHz” or “Wireless 5.0 GHz”, corresponding to their respective frequencies.

When choosing, a menu will appear below and you must click on the option “Wireless Security” to finally change the password. Right next to it, the “Wireless Password” field filled with the current combination will be located.

To change it, just overwrite the old password with a new one and click “Save” at the bottom of the page. The router will restart its functions and thus adopt the new changes. The same procedure can be done to change both types of networks.

How to change your Wi-Fi password on your phone

In some brands of routers, there is the possibility to perform several types of configuration using only the cell phone, through a specific application. In the case of TP-Link routers, there is Tether, available for Android and iOS.

There, you can also change the password for Wi-Fi networks, among many other tools. To start, simply download the application, create a TP-Link ID and perform the Login. Then, it will be necessary to select the router to be configured and enter the administrator credentials (as mentioned in the previous topic, for computers).

When you find the router’s settings interface, just touch the “Tools” icon, found in the lower right corner, select the “Wireless” option, right at the top and, finally, choose the network that should have your password changed. As with the desktop version, just overwrite the old password with the desired new combination and tap the “Save” option. The router will restart to validate the changes.

It is worth mentioning that to access these settings it is necessary to be connected to the router via Wi-Fi or cable, if you are using a computer. You can find the guide for other router models by clicking here.
