It's common to need to connect a new device to a wireless network, but the password itself is lost or forgotten. While wireless devices may already be connected, initial setup or connection of a device without a screen (such as a smart plug) requires entering the correct security key. The most reliable and technically sound way to restore access to this data is to use a wired connection. LAN (Local Area Network).
Connecting via an Ethernet cable offers the user a number of undeniable advantages over hacking attempts or using third-party software. Firstly, connection stability, which is critical when making changes to the router's system configuration files. Secondly, wired access often allows access to the admin panel even if the wireless module is temporarily blocked or malfunctioning. We'll cover the detailed procedure.
Using a cable is not just a way to “pull out” a forgotten code, but also an opportunity to carry out a complete security audit your home network. When connected to the local network via a physical port, you gain access rights that may be limited when connecting via guest Wi-Fi or remotely. This allows you to not only view the current encryption key but also replace it with a more complex one, changing the security type from the outdated one. WEP or WPA to modern WPA2/WPA3.
Physical connection and equipment preparation
The first step to accessing your router's settings is to establish a physical connection between your computer and the router. You'll need a standard network cable. Ethernet, which usually comes with the device (twisted pair with RJ-45 connectors). One end of the cable must be inserted into any of the yellow ports labeled as LAN or LAN 1-4, on the back panel of the router.
The other end of the cable connects to the network card of your laptop or desktop computer. Once connected, the indicators on the ports should light or flash, indicating physical contact. If the indicators don't respond, try replacing the cable or checking the network card, as without an active link, further actions are impossible.
It is important to understand that in most modern operating systems, such as Windows 10/11 or macOS, IP address configuration occurs automatically via the protocol DHCPThis means the computer will automatically obtain the necessary address to communicate with the router. However, if automatic configuration fails, you will need to manually assign addresses within your device's subnet range.
Finding the gateway IP address for logging in
To access the control panel, you need to know the exact IP address of your router, which in network terminology is called default gateway. Default addresses are often listed on a sticker on the bottom of the device, but they may have been previously changed by the administrator. The most common addresses are 192.168.0.1, 192.168.1.1 or 192.168.10.1.
To accurately determine the address in the operating system Windows You can use the command line. Press the key combination Win + R, enter cmd and press Enter. In the black window that opens, enter the command ipconfig and find the line "Default Gateway." The digital code listed there is the address to access the settings.
For users macOS You should go to "System Preferences", select "Network", click on the active Ethernet connection and press the "Advanced" button. In the window that opens, on the tab TCP/IP The router's address will be displayed. This address should be entered into the address bar of any browser (Chrome, Firefox, Opera) to access the administrator interface.
| Router brand | Standard IP | Default login | Default password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| Zyxel | 192.168.1.1 | admin | 1234 |
| Tenda | 192.168.0.1 | admin | admin |
Login to the admin panel
After entering the IP address in the browser, the system will ask for login credentials. This is a critical security step, preventing unauthorized access to network settings. If you've never changed the factory settings, they're usually located on the same sticker as the IP address. A login pair is most commonly used. admin and password admin or 1234.
⚠️ Note: If the default passwords don't work and you haven't changed them, the device may have been reconfigured by your provider or previous owner. In this case, the only solution is to perform a factory reset using the recessed button on the device.
In modern router models, for example, Keenetic or new lines TP-LinkWhen you first log in, you may be asked to create your own administrator password, which is different from your Wi-Fi password. Don't confuse the two: the administrator password gives you access to the router's "brains," while the Wi-Fi password only gives you access to the internet.
If your browser displays a warning that the connection is not secure (SSL certificate error), this is normal for local devices. Since the router doesn't have an official security certificate for the domain name, the browser is warning you of the potential risk. You should click "Advanced" and select "Continue to this site (not secure)" to continue.
What should I do if the page doesn't load?
If the page doesn't open when you enter the IP address, check if you're using a proxy server or VPN. For local connections, you should temporarily disable them in your browser or system settings. Also, make sure the address bar uses the http:// protocol, not https://, although modern routers often redirect traffic automatically.
Finding and viewing your wireless network password
Once inside the interface, you need to find the section responsible for wireless connections. Depending on the model and firmware, this section may be called Wireless, Wi-Fi Settings, "Wireless Mode," or "WLAN." Within this section, look for the "Security" or "Security Settings" subsection.
This is where the key parameters of your network are located: the network name (SSID), the operating mode, and the encryption method. The field containing the password itself is often hidden with asterisks or dots for privacy. Next to this field is usually a "Show Password" checkbox or an eye icon. Clicking it makes the password visible.
In some older interfaces, the password may not be displayed in plaintext even when prompted. In this case, you can use a trick: copy the contents of the field (even if it contains asterisks) and paste it into a macro-enabled text editor or a special field in an online converter. However, modern browsers often block copying of password field contents. A more secure method is to simply replace the old password with a new one you're sure to remember.
Setting up security and changing the access key
Once you've accessed the settings, it's foolish not to take advantage of the opportunity to strengthen your security. The password you saw might be too simple or default. In the "Wireless Password / Pre-shared Key" field, enter a new, complex combination of letters and numbers. It's recommended to use at least 12 characters.
After changing the password and clicking "Save" or "Apply," the router will restart the wireless module. All devices connected to the Wi-Fi network will immediately lose internet access. You'll have to reconnect each smartphone, laptop, and TV using the new access key.
Don't forget that you can also set up a guest network via a LAN cable. This is an isolated Wi-Fi segment for guests who won't have access to your personal files on your computer or network-attached storage (NAS). Creating a guest profile is a best practice if you have frequent visitors.

Alternative methods and resetting settings
If you can't access the settings via LAN because you've forgotten your administrator password, there's a radical but effective method left - Hard Reset. On the back of the router, find the small hole marked Reset or RestoreWith the power on, press it with a paperclip and hold for 10-15 seconds until the indicators blink simultaneously.
This procedure will reset the router to its factory defaults. All settings, including PPPoE data from your ISP, will be deleted. After the reboot, you will be able to log in using the data from the sticker and reconfigure the network using a new, familiar password. Be prepared to reconfigure your internet connection.
There are also specialized utilities for recovering passwords saved in Windows, such as WirelessKeyView or WiFi Password DecoderThey don't work through the router, but scan the operating system registry, where keys for previously connected networks are stored. This can be faster if you don't have a cable handy, but it requires administrator rights on the computer itself.
⚠️ Note: Router interfaces are constantly being updated. The menu item layout may differ from that described depending on your device's firmware version. If you can't find the setting you need, refer to the manufacturer's official documentation or look for screenshots specific to your model.
Frequently Asked Questions (FAQ)
Is it possible to find out a neighbor's Wi-Fi password via LAN?
No, this is technically impossible and illegal. A LAN cable only connects your device to your router. To access someone else's network, you would need to physically connect to their equipment, which is a violation of private property. All the methods described work only within your local network.
What to do if there is no LAN port on the computer?
If you have a modern Ultrabook without an RJ-45 port, you'll need a USB-to-Ethernet adapter. These adapters are available at any electronics store. You can also use an Android smartphone with OTG support, connect the cable through the adapter, and use dedicated network scanning apps, although the functionality will be limited.
Is it safe to store a password in the router settings?
Yes, the password is stored in the router's non-volatile memory. However, if you use a cloud management feature (such as TP-Link Cloud or Keenetic DNS), make sure your account is protected with two-factor authentication to prevent anyone from resetting the settings remotely.
Why doesn't the router accept the new password?
Some older devices may not support certain special characters or have a key length limit (e.g., exactly 8 or 13 characters for WEP, up to 63 for WPA). Try using only Latin letters and numbers, avoiding spaces and symbols like & or ".
