WPS PIN Lookup: HP Printer Edition – A Deep Dive into Wireless Security and Troubleshooting

The modern home and office are increasingly reliant on wireless networks. Connecting devices, especially printers, should be seamless and secure. Wi-Fi Protected Setup (WPS) was designed to simplify this process, offering a convenient alternative to manually entering lengthy Wi-Fi passwords (SSID and passphrase). However, WPS, particularly the PIN method, has known security vulnerabilities and can sometimes be a source of frustration when it doesn’t work as expected. This article provides an in-depth exploration of WPS PIN lookup specifically for HP printers, covering its functionality, security implications, troubleshooting steps, and alternative connection methods.

1. Understanding WPS and Its Methods

Before diving into the specifics of HP printers, it’s crucial to understand the broader context of WPS. WPS is a network security standard created by the Wi-Fi Alliance to make it easier for users to connect devices to a wireless network. It aims to simplify the setup process, particularly for users who might not be technically proficient. WPS offers several connection methods:

  • Push Button Configuration (PBC): This is the most common and arguably the most user-friendly method. It involves pressing a physical or virtual WPS button on both the router and the device (in this case, the HP printer) within a short timeframe (usually two minutes). The devices then automatically negotiate a secure connection.

  • PIN (Personal Identification Number) Method: This method involves entering an 8-digit PIN, typically found on a label on the router or accessible through the router’s web interface. The PIN is entered into the device attempting to connect (the printer), and the router verifies the PIN to grant access.

  • Near Field Communication (NFC): Some devices support NFC, allowing for a connection by simply bringing the device close to the router. This method is less common in printers.

  • USB Flash Drive (UFD) Method: This method, now largely deprecated, involved using a USB drive to transfer network settings from the router to the device.

This article focuses primarily on the PIN method, as it’s the method relevant to “WPS PIN lookup” and often presents the most challenges.

2. Why WPS PIN Lookup is Necessary (and Problematic) for HP Printers

The WPS PIN method, while seemingly convenient, has a fundamental flaw. The 8-digit PIN is susceptible to brute-force attacks. This is because the PIN validation process is split into two halves. The first four digits are checked, and then the last four digits (the last digit is a checksum). This significantly reduces the number of possible combinations an attacker needs to try. A dedicated attacker with the right tools can crack a WPS PIN in a matter of hours, sometimes even minutes.

Despite this vulnerability, many HP printers, especially older models, still rely on the WPS PIN method as a primary or secondary connection option. This necessitates a “WPS PIN lookup” in several scenarios:

  • The WPS button method fails: If the push-button method doesn’t work (due to timing issues, interference, or router/printer incompatibility), the printer may default to requesting the WPS PIN.

  • The printer’s control panel prompts for a PIN: Some HP printers, especially those with limited or no display screens, may directly prompt for the WPS PIN as the only WPS option.

  • Troubleshooting network connectivity issues: Understanding the WPS PIN and its status can be helpful in diagnosing connection problems, even if you ultimately choose a different connection method.

  • Legacy printer setup: Older HP printers might not have the latest firmware updates and might be more reliant on the WPS PIN method.

  • User Preference: In rare cases a user may prefer the PIN method, although this is strongly discouraged.

The need for WPS PIN lookup highlights a tension between convenience and security. While the PIN method aims to simplify the setup, its inherent vulnerability makes it a risky choice.

3. Finding the WPS PIN for Your HP Printer: Multiple Methods

HP, recognizing the various ways users might need to access the WPS PIN, provides several methods for retrieval. The specific method that applies to your printer depends on the model, its features (e.g., presence of an LCD screen), and its current connection status.

  • 3.1. Printing a Network Configuration Page (Recommended for initial setup and troubleshooting):

    This is often the most reliable and readily available method, especially if the printer is not currently connected to the network. The Network Configuration Page (or Network Test Report) contains a wealth of information about the printer’s network settings, including the WPS PIN.

    • General Instructions (these may vary slightly depending on the printer model):

      1. Ensure the printer is powered on and has paper loaded.
      2. Locate the “Wireless” button or a button with a similar icon (often a radio wave symbol). On some models, this might be combined with another button, requiring a press-and-hold action. Consult your printer’s manual if you’re unsure.
      3. Press and hold the Wireless button (and/or the Information button, if required) for a specific duration (usually 5-10 seconds). The printer will then print the Network Configuration Page. Some printers may require you to navigate a menu on a small LCD screen to find the “Print Network Configuration Page” or “Print Network Test Report” option.
      4. Examine the printed page. Look for a section labeled “WPS PIN,” “Wi-Fi Protected Setup PIN,” or similar. The 8-digit PIN will be listed there.

    • Specific Examples (Illustrative):

      • HP DeskJet 2700 series: Press and hold the Wireless button and the Information button simultaneously for 3 seconds.
      • HP ENVY 6000 series: On the printer control panel, touch the Wireless icon, then touch Settings. Touch “Print Details” or “Network Configuration Page.”
      • HP LaserJet Pro M15w: Press and hold the Resume/Cancel button until the Ready light starts blinking.
      • HP OfficeJet Pro 9010 series: From the printer control panel, swipe down to open the Dashboard, then touch the Setup icon. Touch “Network Setup,” then touch “Print Network Configuration Page.”

    • Troubleshooting the Network Configuration Page Print:

      • Printer doesn’t respond: Ensure the printer is properly connected to power and has no error messages displayed. Try restarting the printer.
      • Page doesn’t print: Check for paper jams, low ink/toner, or other hardware issues.
      • WPS PIN is not listed: The printer may not support the WPS PIN method, or WPS may be disabled. Check the printer’s manual or the HP support website for your specific model.

  • 3.2. Using the HP Smart App (If the printer is already connected to the network):

    The HP Smart app, available for Windows, macOS, iOS, and Android, provides a convenient way to manage your HP printer. If the printer is already connected to your Wi-Fi network, the app can often display the WPS PIN.

    1. Install and open the HP Smart app. Ensure your computer or mobile device is connected to the same Wi-Fi network as the printer.
    2. Add your printer to the app (if it’s not already listed). The app should automatically detect the printer.
    3. Select your printer from the app’s home screen.
    4. Navigate to the printer’s settings. The exact location of the WPS PIN information varies depending on the app version and printer model, but it’s typically found under “Network Settings,” “Advanced Settings,” or “Wi-Fi Direct.” Look for “WPS PIN,” “Wi-Fi Protected Setup,” or a similar label.

    5. The app may display the WPS PIN directly, or it may provide a button to generate a new PIN.

    6. Important Considerations:

      • This method only works if the printer is already connected to the network. If you’re trying to establish the initial connection, this method won’t be helpful.
      • The HP Smart app may not support all printer models, especially older ones.
      • The app’s interface and features can change with updates, so the exact steps may vary.

  • 3.3. Accessing the Printer’s Embedded Web Server (EWS) (If the printer is already connected to the network):

    Most network-connected HP printers have an Embedded Web Server (EWS), which is a web-based interface that allows you to configure the printer’s settings. Like the HP Smart app, the EWS can often display the WPS PIN if the printer is already on the network.

    1. Obtain the printer’s IP address. You can find this on the Network Configuration Page (see section 3.1) or through the HP Smart app.
    2. Open a web browser (e.g., Chrome, Firefox, Edge) on a computer or device connected to the same network as the printer.
    3. Enter the printer’s IP address into the browser’s address bar and press Enter. This should open the printer’s EWS.
    4. Navigate to the network settings. The exact location of the WPS PIN information varies depending on the printer model and EWS version, but it’s typically found under “Network,” “Wireless,” “Wi-Fi Protected Setup,” or a similar section.

    5. Look for the WPS PIN or an option to generate a new PIN. You may need to log in to the EWS with an administrator password (if one is set). The default password is often blank or “admin.” Consult your printer’s manual for details.

    6. Important Considerations:

      • The EWS may not be available on all printer models.
      • The EWS interface can be complex, and the location of the WPS PIN settings may not be immediately obvious.
      • Accessing the EWS requires knowing the printer’s IP address.

  • 3.4. Checking the Router’s Label (Less Likely, but Possible):

    While the WPS PIN is primarily associated with the printer, some routers (especially older models) might have the default WPS PIN printed on a label on the router itself. This is not the recommended way to find the printer’s WPS PIN, as the router’s PIN and the printer’s PIN are usually different. However, it’s worth checking as a last resort, especially if you’re dealing with an older router and printer.

    • Important Note: If you find a WPS PIN on your router, do not assume it’s the same as the printer’s PIN. Using the wrong PIN can cause connection problems. It’s best used to disable WPS on the router.

  • 3.5 Contacting HP Support:
    If none of the above methods work, contacting HP support is your final option. They can guide you through specific troubleshooting steps for your printer model or help you find the WPS PIN.

4. The WPS PIN Generation Process (and Why It Matters)

It’s important to understand that the WPS PIN is not always a static, pre-programmed number. Some HP printers generate a new WPS PIN each time the WPS setup process is initiated. This dynamic PIN generation adds a (small) layer of security, as it limits the window of opportunity for an attacker to brute-force the PIN.

Here’s how the PIN generation process typically works:

  1. WPS Initiation: You initiate the WPS connection process, either through the printer’s control panel, the HP Smart app, or by pressing the WPS button on the router.
  2. PIN Generation: The printer generates a new, random 8-digit WPS PIN.
  3. PIN Display (Optional): The printer may display the PIN on its control panel (if it has a screen) or make it available through the HP Smart app or EWS.
  4. PIN Entry: You enter the generated PIN into the router’s WPS setup interface (if required). Alternatively, if using the push-button method, the PIN exchange happens automatically.
  5. Connection Establishment: If the PIN is correct (and the router accepts it), the printer connects to the Wi-Fi network.
  6. PIN Expiration: After a short period (usually a few minutes), the generated WPS PIN becomes invalid. This is a security measure to prevent attackers from exploiting the PIN after the connection is established.

The dynamic PIN generation process means that simply looking up the WPS PIN on a previously printed Network Configuration Page might not work if a significant amount of time has passed. You might need to initiate the WPS process again to generate a new PIN.

5. Step-by-Step WPS PIN Connection Process (with HP Printer Examples)

Let’s illustrate the WPS PIN connection process with a few specific HP printer examples. Remember that the exact steps may vary slightly depending on the printer model.

  • Example 1: HP DeskJet 2755e (using Network Configuration Page and manual PIN entry):

    1. Print the Network Configuration Page: Press and hold the Wireless button and the Information button simultaneously for 3 seconds.
    2. Locate the WPS PIN: On the printed page, find the “WPS PIN” section. Note the 8-digit number.
    3. Access your router’s configuration page: Open a web browser and enter your router’s IP address (usually 192.168.1.1 or 192.168.0.1). Log in with your router’s username and password.
    4. Find the WPS settings: Navigate to the wireless settings section of your router’s interface. Look for “WPS” or “Wi-Fi Protected Setup.”
    5. Choose the PIN method: Select the option to connect using the WPS PIN.
    6. Enter the PIN: Enter the 8-digit WPS PIN you found on the Network Configuration Page.
    7. Start the connection process: Click “Connect,” “Start,” or a similar button on your router’s interface. The router will attempt to connect to the printer.
    8. Wait for connection: The printer and router will negotiate the connection. This may take a few minutes. The printer’s wireless light should become solid once the connection is established.

  • Example 2: HP ENVY 6055e (using HP Smart app):

    1. Ensure the printer is already connected to the Wi-Fi network. This example assumes you’ve previously connected the printer and are now trying to retrieve the PIN.
    2. Open the HP Smart app on your computer or mobile device.
    3. Select your HP ENVY 6055e printer from the app’s home screen.
    4. Navigate to “Advanced Settings” or “Network Settings.” The exact location may vary.
    5. Look for “WPS PIN” or “Wi-Fi Protected Setup.”
    6. The app may display the current WPS PIN or provide an option to generate a new one.

  • Example 3: HP LaserJet Pro MFP M28w (using Embedded Web Server):

    1. Ensure the printer is connected to the Wi-Fi.
    2. Obtain the printer’s IP address: Print a Network Configuration Page (press and hold the Resume/Cancel button until the Ready light blinks).
    3. Open a web browser and enter the printer’s IP address.
    4. Log in to the EWS (if prompted). The default username is often blank, and the password might be “admin” or blank. Consult the manual.
    5. Navigate to “Networking” > “Wireless (802.11)” > “WPS.”
    6. You should see the current WPS PIN or an option to generate a new one.

6. Troubleshooting WPS PIN Connection Problems

Even with careful steps, WPS PIN connections can fail. Here’s a breakdown of common problems and their solutions:

  • 6.1. Incorrect WPS PIN:

    • Problem: You’re entering the wrong PIN. This is the most common reason for failure.
    • Solutions:
      • Double-check the PIN: Carefully re-examine the Network Configuration Page, HP Smart app, or EWS to ensure you’re entering the correct 8-digit number. Pay attention to similar-looking characters (e.g., 0 and O, 1 and l).
      • Generate a new PIN: If the printer supports dynamic PIN generation, initiate the WPS process again to generate a fresh PIN.
      • Ensure you’re using the printer’s PIN, not the router’s: The router’s WPS PIN (if it has one) is usually different from the printer’s PIN.

  • 6.2. WPS is Disabled on the Router or Printer:

    • Problem: WPS might be disabled on either the router or the printer, preventing the connection.
    • Solutions:
      • Enable WPS on the router: Access your router’s configuration page and navigate to the wireless settings. Look for a WPS setting and ensure it’s enabled. However, strongly consider disabling WPS permanently after setup due to security concerns.
      • Enable WPS on the printer: Check the printer’s control panel, HP Smart app, or EWS for WPS settings. Ensure WPS is enabled. Some printers may have a physical WPS button that needs to be pressed.

  • 6.3. Router and Printer Incompatibility:

    • Problem: In rare cases, the router and printer might be incompatible with each other’s WPS implementation.
    • Solutions:
      • Update firmware: Check for firmware updates for both your router and your HP printer. Manufacturers often release updates to improve compatibility and address known issues.
      • Try a different connection method: If WPS consistently fails, consider using a different connection method, such as manually entering the Wi-Fi password (SSID and passphrase) or using a USB cable for initial setup.

  • 6.4. Timing Issues (for Push-Button WPS):

    • Problem: The WPS buttons on the router and printer must be pressed within a short timeframe (usually two minutes) of each other. If you’re too slow, the connection will fail.
    • Solutions:
      • Press the buttons simultaneously (or as close as possible): Coordinate the button presses to ensure they occur within the allowed timeframe.
      • Check for interference: Physical obstructions or other wireless devices can sometimes interfere with the WPS signal. Try moving the printer closer to the router or temporarily disabling other wireless devices.

  • 6.5. Wireless Interference:

    • Problem: Other wireless devices or sources of electromagnetic interference (e.g., microwave ovens) can disrupt the WPS connection process.
    • Solutions:
      • Move the printer closer to the router: Reduce the distance between the devices to minimize interference.
      • Temporarily disable other wireless devices: Turn off other devices that might be using the 2.4 GHz band (e.g., cordless phones, Bluetooth devices).
      • Change the router’s wireless channel: Access your router’s configuration page and try changing the wireless channel to a less congested one.

  • 6.6. Router’s WPS PIN Limit Reached:

    • Problem: Some routers have a limit on the number of WPS PIN attempts allowed within a certain timeframe. If you’ve made too many unsuccessful attempts, the router might temporarily block WPS connections.
    • Solutions:
      • Wait: Wait for the lockout period to expire (this can vary from a few minutes to several hours).
      • Restart the router: Power cycling the router can sometimes reset the WPS attempt counter.
      • Use a different connection method: If you’re consistently exceeding the PIN attempt limit, consider using a different connection method.

  • 6.7. Firewall or Security Software Interference:

    • Problem: A firewall or security program on your computer might be blocking the communication between the printer and the router during the WPS setup.
    • Solutions:
      • Temporarily disable firewall/security software: Temporarily disable your firewall or security software and try the WPS connection again. If it works, you’ll need to configure your security software to allow communication with the printer. Re-enable your firewall immediately after.
      • Add the printer to the firewall’s exception list: Consult your firewall’s documentation for instructions on how to add an exception for the printer’s IP address or MAC address.

7. Alternatives to WPS PIN for Connecting Your HP Printer

Given the security vulnerabilities of the WPS PIN method, it’s highly recommended to explore alternative connection methods. These methods are generally more secure and often just as easy to use.

  • 7.1. Manual Wi-Fi Setup (SSID and Passphrase):

    This is the most secure and reliable method. It involves manually entering your Wi-Fi network’s name (SSID) and password (passphrase) into the printer’s control panel or using the HP Smart app.

    1. Find your Wi-Fi network name (SSID) and password (passphrase). This information is usually printed on a label on your router or provided by your internet service provider.
    2. On the printer’s control panel (if it has one), navigate to the wireless settings menu. Look for an option like “Wireless Setup Wizard,” “Manual Setup,” or “Enter Network Name and Password.”
    3. Select your Wi-Fi network from the list of available networks (or manually enter the SSID if it’s not listed).
    4. Enter your Wi-Fi password (passphrase) carefully. Pay attention to capitalization and special characters.

    5. The printer should connect to the network. The wireless light should become solid.

    6. Using HP Smart App:

      1. Open the HP Smart App.
      2. Add a new Printer
      3. The app will search for networks.
      4. Choose your network and enter the passphrase.

  • 7.2. Wi-Fi Direct (Printer as Access Point):

    Wi-Fi Direct allows you to connect your computer or mobile device directly to the printer without needing a router. The printer creates its own Wi-Fi network. This is useful for printing from mobile devices or when a traditional Wi-Fi network isn’t available.

    1. Enable Wi-Fi Direct on your HP printer. This is usually done through the printer’s control panel, HP Smart app, or EWS.
    2. On your computer or mobile device, search for available Wi-Fi networks. You should see a network name that starts with “DIRECT-” followed by your printer’s model name.
    3. Select the Wi-Fi Direct network and enter the Wi-Fi Direct password. This password is often displayed on the printer’s control panel or can be found in the HP Smart app or EWS.

    4. Once connected, you can print directly to the printer.

    5. Important Considerations:

      • Wi-Fi Direct creates a separate network, so your computer or mobile device won’t be connected to the internet while connected to the printer.
      • The Wi-Fi Direct password should be kept secure to prevent unauthorized access to your printer.

  • 7.3. USB Connection (for Initial Setup):

    You can use a USB cable to connect your printer to your computer for initial setup. This allows you to configure the printer’s wireless settings without relying on WPS.

    1. Connect the printer to your computer using a USB cable.
    2. Install the HP printer drivers and software on your computer. You can download the drivers from the HP support website.
    3. During the installation process, you’ll be prompted to choose a connection method. Select “Wireless” and follow the on-screen instructions to configure the printer’s Wi-Fi settings.
    4. Once the wireless setup is complete, you can disconnect the USB cable.

  • 7.4 Ethernet Connection (If Available):
    Some HP Printers, usually higher end office models, have an Ethernet port. This provides the most stable and secure network connection.

8. Disabling WPS: A Crucial Security Step

After successfully connecting your HP printer to your Wi-Fi network using a secure method (like manual Wi-Fi setup), it’s strongly recommended to disable WPS on both your router and your printer. This eliminates the risk of WPS-based attacks.

  • Disabling WPS on your Router:

    1. Access your router’s configuration page: Open a web browser and enter your router’s IP address (usually 192.168.1.1 or 192.168.0.1). Log in with your router’s username and password.
    2. Find the WPS settings: Navigate to the wireless settings section of your router’s interface. Look for “WPS” or “Wi-Fi Protected Setup.”
    3. Disable WPS: Select the option to disable WPS. The exact wording may vary (e.g., “Disable,” “Off,” “Deactivate”).
    4. Save your changes: Click “Save,” “Apply,” or a similar button to save the new settings. Your router may reboot.

  • Disabling WPS on your HP Printer:

    The method for disabling WPS on your HP printer varies depending on the model. Check the printer’s control panel, HP Smart app, or EWS for WPS settings. Look for an option to disable WPS. If you can’t find a specific setting to disable WPS, it might be disabled automatically after a successful connection using a different method. Consult your printer’s manual for details.

9. Firmware Updates: Keeping Your Printer Secure

Regularly updating your HP printer’s firmware is crucial for security and performance. Firmware updates often include patches for security vulnerabilities, bug fixes, and improved compatibility.

  • Checking for Firmware Updates:

    • HP Smart App: The HP Smart app usually notifies you when a firmware update is available. You can also manually check for updates within the app.
    • Embedded Web Server (EWS): Access the printer’s EWS and look for a “Firmware Update” or “Check for Updates” option.
    • HP Support Website: Visit the HP support website and search for your printer model. You can download the latest firmware from there.

  • Installing Firmware Updates:

    Follow the instructions provided by HP for installing the firmware update. This usually involves downloading the update file and then uploading it to the printer through the HP Smart app, EWS, or a USB connection. Do not interrupt the firmware update process, as this can damage the printer.

10. Conclusion: Prioritizing Security Over Convenience

WPS PIN lookup for HP printers, while sometimes necessary for connecting older or less-featured models, highlights the inherent security risks of the WPS PIN method. The convenience of a simple PIN is overshadowed by its vulnerability to brute-force attacks.

The best practice is to avoid using WPS altogether. Instead, opt for secure connection methods like manual Wi-Fi setup (using the SSID and passphrase) or Wi-Fi Direct. If you must use WPS, disable it immediately after successfully connecting the printer.

Regularly updating your printer’s firmware and disabling WPS on both your router and printer are crucial steps in protecting your network from unauthorized access. By prioritizing security over convenience, you can ensure that your HP printer remains a valuable asset without compromising your network’s integrity.
