When you buy a new router or receive equipment from your internet service provider, there's often a plastic card or sticker on the device itself containing critical information for initial setup. Many users mistakenly believe this information is only for technicians, but that's precisely where the secret lies. factory password to connect to a wireless network. Understanding how to correctly read this data will save you from having to reset your device to factory settings or call support.
The question "What is the Wi-Fi card called?" often arises due to confusion in terminology: users are looking for a "password," but instead see complex combinations of letters and numbers labeled as PIN or Key. In fact, this plastic card (or sticker on the bottom of the case) is the physical carrier of the unique identification data for your router model. WPS PIN, SSID And Wireless Key — these are standard designations that must be distinguished for successful authorization on the network.
In this article, we'll cover exactly where to find the required numbers, how they differ from each other, and what to do if the sticker has worn off or been removed by the previous owner. We'll also cover security issues, explaining why it's best not to leave this data in a publicly accessible location after setup.
Main markings on the router's factory sticker
A plastic card or sticker on the device's body usually contains several lines of alphanumeric codes. The most important line for connecting to Wi-Fi is often labeled as Wireless Key, WPA Key or simply PasswordThis is the password you're looking for, the one your smartphone or laptop asks for when trying to connect to the hotspot. The length of such a key is usually between 8 and 13 characters, although modern encryption standards WPA3 can use longer sequences.
Next to the password there is almost always a network name, which is called in technical documentation SSID (Service Set Identifier). By default, it is often formed from the router brand name and the last characters of its MAC address, for example, TP-LINK_5A2BIf you see two values on the map—one short and one long—then the short one is most likely the network name and the long one is the password. However, in some models, especially from Keenetic or MikroTik, there may be no default password at all, and the field will be marked as empty or a dash.
⚠️ Attention: If your plastic card has a value
WPS PINThis is NOT your Wi-Fi password. It's an eight-digit code for quick pairing of devices and is not suitable for manually entering the password in the network selection menu on your phone.
Some manufacturers, such as Asus or ZyxelA QR code is placed on the same card. Scanning this code with a smartphone camera can automatically transfer login data to the operating system, eliminating manual entry. This is especially convenient if the factory password contains complex characters that are easily confused, such as zero and the letter "O," or one and the letter "l."
Differences between WPS PIN, SSID and Wireless Key
To properly configure your network, you need to clearly understand the difference between the three main parameters shown on the map. SSID — This is the visible name of your network, which appears in the list of available connections. It's not secret, but it's important to know it to select the right access point from neighboring networks with similar names.
Wireless Key (or WPA-PSK) is the secret encryption key. It is verified upon connection. Without this combination of characters, it is impossible to access the internet through your access point (assuming encryption is enabled). This key must be entered with care: lowercase and uppercase letters matter.
The third parameter is - WPS PINWi-Fi Protected Setup technology allows you to connect devices without entering a long password, simply by entering the PIN in the appropriate menu or pressing a button on the router. However, from a security standpoint, using WPS is considered a security vulnerability, and many experts recommend disabling this feature in the router settings immediately after initial setup.
- 🔑 Wireless Key — the main password for Internet access, requires accurate entry.
- 📡 SSID — the network name visible to all surrounding devices within range.
- 🔢 WPS PIN — a code for quick, but less secure pairing of gadgets.
Where is the information physically located on the equipment?
The information card may be a separate plastic insert in the box or, more commonly, a paper sticker attached directly to the router body. If it's a plastic insert, it's often the size of a credit card and bears the provider's or manufacturer's logo. The back of such a card sometimes contains brief instructions on how to log into the web interface for the first time.
If you're looking for data on the device itself, turn the router over. There should be an information label on the bottom panel, where the vents and ports are located. Some models, such as some devices, have this label. Tenda or Mercusys, the sticker can be hidden under a removable stand or located on the side edge next to the button WPS/Reset.
It's important to note that on devices that have been used or leased from a provider, the original sticker may be covered with another label containing the username and password for the subscriber's personal account. In this case, the factory data may be visually inaccessible. It's also worth considering that heat from the router's operating components can cause paper stickers to fade over time, making the text illegible.
| Manufacturer | Password designation | Location | Peculiarities |
|---|---|---|---|
| TP-Link | Wireless Password / PIN | Bottom panel | Often coincides with the PIN code |
| D-Link | WPA Key | Bottom Panel / Removable Card | May not be available on older models. |
| Keenetic | Net. password | Bottom panel | Unique for each device |
| Asus | Network Key | Bottom panel | Often complex, contains special characters |
☑️ Checking the sticker
What to do if the sticker is worn off or missing
It's quite common for the factory plastic card to be lost and the sticker on the router to be illegible. In this case, don't panic or immediately take the device in for repair. There are several ways to restore network access or find out the current password if you already have at least one connected device, such as a computer using a cable or Wi-Fi connection.
The most reliable method is to log into the router's web interface. To do this, connect to the device (this can be done temporarily via a LAN cable) and enter the IP address in the browser's address bar. This is usually 192.168.0.1 or 192.168.1.1If you've changed your administrator password before, use it. If not, try standard combinations such as admin/admin, which are often indicated in the documentation for the model.
⚠️ Attention: If you decide to reset the router to factory settings by holding down the button
ResetAll your current internet settings (PPPoE, L2TP, static IP) will be deleted. Make sure you know your ISP login and password before performing the reset.
In the router interface, under "Wireless" -> "Wireless Security," you can see the current password. In newer firmware versions, it may be hidden behind asterisks. In this case, you can use the "Show Password" button (the little eye) or simply change it to a new one you'll remember. After changing the password, you'll need to reconnect all devices.
How to view a password on Windows
If your computer is already connected to Wi-Fi, right-click on the network icon -> Network and Sharing Center -> Click on the wireless network name -> Wireless Network (Properties) -> Security tab -> Check the box "Show characters as you type".
Security: Should I use the factory password?
Using the factory password printed on the plastic card is convenient during initial setup, but is not recommended for long-term use. This is because some manufacturers' password generation algorithms can be predictable, and the stickers themselves are physically accessible to anyone with access to your router (for example, in an office or dorm).
An attacker with physical access to your router's model could attempt to brute-force the password using vendor-specific vulnerability databases. Furthermore, default passwords often don't meet modern complexity requirements. It's recommended to change them immediately after purchase. SSID to a unique name and set up a complex WPA2/WPA3 a key containing letters of different cases, numbers and special characters.
It's also important to remember to protect the router's management interface itself. The factory-set passwords for logging into the settings (admin/admin) are publicly known. If you leave them unchanged, anyone connected to your network can gain full control of the router, redirect traffic, or steal data. Changing the administrator password is the first step you should take.
Frequently Asked Questions (FAQ)
Is it possible to restore the factory password if the sticker is completely erased?
It's impossible to restore the factory-generated password if it's not written down anywhere. However, you can reset the router using the reset button. Reset (holding for 10-15 seconds), after which the device will return to factory settings, and the password will become the one specified in the documentation or on the manufacturer's website for your model (if it is not individual), or there will be no need to enter it.
What should I do if the card only has a PIN and no password?
This means that for this router model, the factory Wi-Fi password is the same as the WPS PIN. Try entering the specified PIN as the password when connecting. If it doesn't work, you'll have to connect via cable and check the settings in the web interface.
I changed my password in settings, but forgot the new one. How do I regain access?
The only solution in this situation is to perform a hard reset of the device to factory settings. After this, the router will use the password specified on the plastic card or sticker, as it did when it was first turned on. All personal settings will have to be re-entered.
Where can I get a plastic card if I lost my router components?
Manufacturers typically don't issue a separate plastic card. All necessary information is duplicated on a sticker on the bottom of the case. If the sticker has worn off, find the exact router model (it's listed there) and search online for "default password for [router model]," or use the reset method.
