How to change the password on a Wi-Fi router if you forgot the old one

It's extremely common to need to change a wireless network access key after losing or forgetting the previous one. Users forget complex combinations they created for security purposes or simply can't remember whether they changed the factory settings. Fortunately, the standard security protocol includes a forced reset mechanism that returns the device to its factory defaults.

After completing this procedure, you'll have full control over your router. You'll no longer need to guess the old code or search for worn-out stickers on the bottom of the device. The main thing to understand is: reset settings This will affect not only Wi-Fi, but also your provider connection settings, which will have to be re-entered.

In this guide, we'll cover the steps for most popular hardware models. We'll cover performing a physical reset via the Reset button, logging into the web interface, and properly setting up new encryption to protect your home network from unauthorized access.

Preparing for the factory reset procedure

Before you begin, make sure you have access to the device itself. You'll need physical contact with the router, as it's usually impossible to access the settings programmatically without the administrator password. Locate the button on the device, which may be labeled as Reset, Default or RST.

This button is often recessed into the housing to prevent accidental pressing. To activate it, you'll need a thin object, such as a straightened paperclip, toothpick, or needle. Make sure the router is plugged in and the power indicators are lit—if the device is off, the reset won't work.

It's also important to have your internet service provider contract on hand. After resetting, the router will "forget" the connection type (PPPoE, L2TP, PPTP, or Dynamic IP), as well as the username and password for accessing the global network. Without this information, the internet on computers and phones won't work, even if Wi-Fi is available.

Restoring access requires careful attention. Don't rush, as hasty actions may require calling a technician to reconfigure the equipment. Be sure to have an Ethernet cable, usually included, ready for direct connection to your computer or laptop.

Physical reset via the Reset button

The most reliable way to reset your computer if you've forgotten your administrator password or Wi-Fi key is to perform a hard reset. Find the hole marked Reset on the back or bottom of the device. Insert a paperclip and press the button.

You must hold the button for 10-15 seconds. The indicators on the front panel may blink or go out momentarily—this indicates that the process has initiated. Release the button only after you notice a change in the indicator lights.

⚠️ Caution: Do not unplug the router during the reset process. Interrupting the factory firmware update process may cause a software failure, requiring the device to be taken to a service center.

After releasing the button, the router will reboot. This may take one to three minutes. During this time, the system restores factory settings, including the network name (SSID) and password, which are located on a sticker under the router.

Now your router is as clean as the day you bought it. You can connect to it using the default credentials and log into the control panel to configure new security settings.

Login to the router control panel

After a successful reset, you need to connect to the device. Do this via Wi-Fi using the default password on the sticker, or, more securely, via a LAN cable, plugging one end into the router port and the other into the computer's network card.

Open any browser and enter the device's IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1The exact address is also indicated on a sticker on the bottom of the case. If the page doesn't load, check your network card settings—they should be set to "Obtain IP automatically."

The browser will ask for authorization. Enter the default login and password. For most models, this is a pair admin / admin or admin / passwordThis information can also be found on the device label.

If you see the main settings menu, you've gained access. The interface may vary depending on the manufacturer, but the logic is the same everywhere. Look for sections labeled "Wireless," "Wi-Fi," "Wireless Network," or "WLAN."

Setting up a new Wi-Fi password

In the settings menu, go to the section responsible for wireless network. You need to find the field Wireless Password, WPA-PSK Key or "Wireless Network Password." This is where you set the code that your guests and devices will enter.

Create a secure password. It should contain at least 8 characters, including uppercase and lowercase letters, as well as numbers. Avoid using simple sequences like "12345678" or your date of birth.

Please pay attention to the encryption type. It is recommended to choose WPA2-PSK or WPA3, if your equipment supports this standard. The older WEP protocol is considered insecure and easily cracked.

⚠️ Note: After saving the new settings, all devices connected to Wi-Fi will lose their internet connection. You will need to re-enter the new password on every smartphone, tablet, and laptop in your home.

Don't forget to click "Save" or "Apply" at the bottom of the page. Your router may reboot for the changes to take effect. Afterward, your network will be accessible with the new name (if you changed it) and a new access key.

Changing the administrator password

While you're still logged into the control panel, it's crucial to change the router's password. Factory default passwords like "admin" are known to hackers and malware. If left unchangeable, an attacker can redirect your traffic to their servers.

Find the "System Tools," "Administration," "Management," or "System" section. In the "New Password" field, enter a complex code you won't forget. This will be the key to the "back door" to your network.

Write this password down in a safe place. If you forget it again, you'll have to repeat the physical reset procedure using the Reset button, which is less convenient.

What happens if I don't change the administrator password?

An attacker who gains access to your router can change DNS servers. As a result, when you try to access your online banking, you could be redirected to a fake website where your data will be stolen.

Changing the administrator password will significantly strengthen the router's security. Now, only the device owner with the unique password can access the settings.

Table of standard addresses and passwords

If you've reset your settings but can't access the control panel, use the table below. It includes the most common combinations for popular brands.

Please note that on some models, the password field may be blank. In this case, simply leave it blank and click "Login." If none of the combinations work, carefully inspect the sticker on the bottom of the device—manufacturers often provide personal information there.

It's becoming standard for modern routers to use domain names instead of IP addresses. For example, for TP-Link, this might be tplinkwifi.net, and for Asus - router.asus.comThis makes access easier since you don't have to remember numbers.

Setting up a connection to your provider

After changing your passwords, don't forget to set up your internet connection. Go to the "Network," "WAN," or "Internet" section. Select the connection type your provider uses. This information is included in your contract.

If you use a dynamic IP, internet access will be available immediately after connecting the cable. If PPPoE, L2TP, or PPTP is required, enter the username and password from the contract in the appropriate fields.

⚠️ Please note: Router interfaces are constantly being updated. The layout of menu items may differ from those described. Always consult the official instructions on the manufacturer's website for your model.

After entering all parameters, save the settings. The router will attempt to establish a connection. If the global network indicator (usually marked with the letter W or the Earth icon) lights up or blinks, which means the Internet is working.
