In today's digital world, a wireless network has long since ceased to be a mere convenience, becoming a critical infrastructure for work, entertainment, and smart home management. However, an open or poorly secured access point becomes easy prey for attackers, who can not only steal your traffic but also access personal files on connected devices. This is why setting a PIN code on a Wi-Fi router is a top priority for every network equipment owner.
Many users confuse the concepts, believing that a standard wireless network password (WPA2/WPA3) is sufficient for complete security. In fact, there are additional authentication mechanisms, such as WPS (Wi-Fi Protected Setup), that require special attention and configuration. PIN code In this context, it can mean either a code for quick connection via WPS, or, more importantly, a code for logging into the administrator's web interface, without which it is impossible to change security settings.
In this article, we'll detail the process of setting and changing security codes on various router models, explain the differences between them, and help you create an impenetrable security perimeter. You'll learn why the default values listed on the device's sticker pose a significant risk and how to properly replace them with unique combinations.
Differences between a Wi-Fi password and a WPS passcode
Before you begin any technical manipulations, it's important to clearly understand the terminology, as confusion here can lead to losing access to your network. A Wi-Fi password (security key) is a long combination of characters you enter on your phone or laptop to connect to the internet. It encrypts traffic between the device and the router using protocols. WPA2 or WPA3.
On the other side, WPS PIN code A WPS passcode is an 8-digit combination designed to simplify connecting devices without entering a long password. This feature was created for convenience, but from a cybersecurity standpoint, it's one of the most vulnerable points. If WPS is enabled on a router and a weak or default PIN is set, an attacker can brute-force it in a matter of hours, even without knowing the main Wi-Fi password.
⚠️ Attention: The WPS function has a fundamental vulnerability in the protocol that allows the PIN code to be recovered knowing only the first four digits. It is recommended to completely disable this feature in your router settings if you don't use it regularly.
There's also a third type of code—the administrator password. This is the key requested when accessing the router settings through a browser (usually at 192.168.0.1 or 192.168.1.1). Changing the factory administrator password is a mandatory step before making any other security adjustments.
Preparing for setup: connecting and logging into the interface
To begin setting security codes, you need to access the router's control panel. This can only be done from a device already connected to the network, preferably via an Ethernet cable to avoid losing the connection while changing wireless network settings.
Take a computer or laptop and connect it to any of the router's LAN ports (usually yellow and numbered). Open any browser and enter your device's IP address in the address bar. Most often, this is 192.168.0.1, 192.168.1.1 or 192.168.31.1The exact address, as well as the default login and password, are always indicated on a sticker on the bottom of the router.
- 🔌 Connect your device to the router via a LAN cable for a stable connection.
- 🌐 Open your browser and enter the gateway IP address in the address bar.
- 🔑 Enter the administrator login and password (by default, often admin/admin).
- 📱 If a cable is unavailable, connect to the router's Wi-Fi network, but be prepared for connection interruptions.
After successful authorization, you will see the main page of the web interface. Interfaces from different manufacturers (TP-Link, Asus, Keenetic, MikroTik) look different, but the logic behind the security sections is similar. Find the tab labeled "Wireless," "Wireless Mode," "Wi-Fi Network," or "Security."

Instructions: How to change the WPS PIN on different routers
Let's look at the process of changing or disabling the WPS PIN using examples from popular manufacturers. Remember, the main goal is to either set a complex, unique code that's impossible to guess, or completely disable the feature if you don't need it.
For routers TP-Link (green interface): go to the menu Wireless -> WPSHere you'll see the current status and PIN value. Clicking "Change PIN" or "Generate New PIN" will generate a new random combination. It's recommended to immediately click "Disable WPS" to completely close this loophole.
In devices Asus with AsusWRT firmware: in the left menu column, select Wireless network -> tab WPSIn the "WPS Router PIN Code" section, you can see the current code. To change it, you often need to first disable WPS, save the settings, and then enable it again—the system will generate a new code. However, as in the previous case, it's wiser to leave the switch on. Enable WPS in position Off.
Routers Keenetic (formerly Zyxel) have the most flexible settings. In the menu My Networks and Wi-Fi -> Home network You can find the WPS settings here. The security system will automatically warn you of any risks. Check "Use PIN" only if absolutely necessary, and change it regularly using the refresh button.
⚠️ Attention: Firmware interfaces are regularly updated by manufacturers. The menu layout may differ from the one described. If you don't find an exact match, look for sections labeled "Wireless," "Security," or "WPS."
Why can't you just change the numbers?
Simply replacing the digits in the WPS code (for example, from 12345678 to 12345679) doesn't protect against automated scanners that try every combination. The only reliable protection is disabling the WPS function in the router settings.
Setting a strong password for your wireless network
Along with setting up WPS, it's critical to secure the communication channel itself. Even if WPS is disabled, a weak Wi-Fi password will allow a hacker to connect to the network and intercept data. Go to the section Wireless Security or Wireless Network Security.
In the field Version or Security Mode select protocol WPA2-PSK [AES] or, if your hardware supports it, WPA3-PersonalAvoid using outdated standards. WEP or WPA/TKIP, as they can be hacked in minutes using modern tools.
In the "Password" or "Wireless Password" field, enter a new access key. It must meet the following requirements:
- 🔒 Contain at least 12 characters (optimally 16-20).
- 🔢 Include numbers, uppercase and lowercase letters.
- 🚫 Do not contain obvious words, birth dates or sequences (12345678).
- 🎲 Be unique to your network and not used on other sites.
After entering the new password, click the button Save or ApplyThe router will reboot the wireless module, and all connected devices will lose connection. You will need to re-enter the new password on each smartphone, tablet, and computer.
Changing the router administrator password
Last but not least, protect the "control panel" of your internet. By default, most routers have an account. admin with a password admin or 1234Anyone who understands even a little about technology knows this.
To change this password, find the section System Tools, Administration or System tools -> PasswordHere you'll be asked to enter the old (factory) password and create a new one. Create a strong combination, different from your Wi-Fi password, so that if one password is compromised, the other remains secure.
After changing the administrator password and saving the settings, you'll likely be redirected to the login page. Enter the new login information. From now on, access to the router settings will only be possible with the new code.
| Parameter | Factory Value (Example) | Recommended value | The risk of ignoring |
|---|---|---|---|
| Wi-Fi password | Missing or on sticker | WPA2, 16+ characters, random | Traffic theft, file access |
| WPS PIN | Static (on the sticker) | Disabled or changed | Network hacking in 4-10 hours |
| Admin password | admin / admin | Unique complex phrase | Full control over your router |
| Encryption protocol | WEP / WPA-TKIP | WPA2-AES / WPA3 | Intercepting cleartext passwords |
Frequently Asked Questions (FAQ)
I forgot my new Wi-Fi password and can't connect. What should I do?
If you've forgotten your wireless network password but have a computer connected to the router via cable, you can view or change the password in the web interface's wireless security section. If you don't have a cable connection, you'll need to reset the router using the reset button on the router, which will restore it to the factory defaults listed on the sticker.
Is it possible to set a PIN code for guests only?
Yes, modern routers support the "Guest Network" feature. You can activate it, set a separate network name (SSID) and your own password. This will allow guests to use the internet but isolate them from your personal devices, such as NAS storage, printers, and computers.
Does a complex password affect internet speed?
No, password complexity (number of characters and symbols) doesn't affect data transfer speed. However, the choice of encryption protocol does: using the older WEP protocol can limit speed, while WPA2-AES and WPA3 operate at the full speed of your data plan and equipment.
How often should I change my router passwords?
Security experts recommend changing your Wi-Fi password and administrator password at least every 6-12 months, or immediately if you suspect unauthorized access. You should also change your password if you've separated from someone you previously shared the code with.
