When attempting to wirelessly connect to an office or home laser device, users often encounter an unexpected request for credentials. Model HP Laser 135w Supports Wi-Fi Direct technology, which allows printing without a router, but requires a security code. This code is often confused with a home network password, but it is unique to each device and serves to protect the printing environment from unauthorized access.
By default, the factory configuration sets a certain PIN code, which is indicated on the sticker on the back of the device or in the device's menu. If the default combinations don't work, it means the settings have been changed by a previous user or network administrator. In this case, you'll need to reset the network settings to factory defaults, which will restore the original access data.
In this article, we will look at all possible options for restoring access to MFPYou'll learn where to find factory information, how to use the built-in control panel to view current settings, and how to perform a full network reset. We'll also cover the nuances of working with mobile apps and drivers that may request this data at the most inopportune moment.
Factory data and location of the information sticker
The first step in finding lost authorization data is a physical inspection of the device. Manufacturer Hewlett-Packard The printer places service information on a special label. It's usually located on the rear panel of the device, near the USB port and power connector. On some models, the label may be hidden under the opening paper tray or on the inside of the front cover.
On the label you are interested in the line with the name Wi-Fi Direct PIN or simply PINThis is an eight-digit numeric code that is required when pairing your smartphone or laptop with the printer for the first time. It is important not to confuse it with MAC address or the serial number of the device, which is also present on the sticker.
⚠️ Note: If the sticker is worn, damaged, or peeled off, you won't be able to visually identify the factory password. In this case, the only solution is to perform a soft reset via the device menu, which is discussed below.
Sometimes users encounter a situation where the sticker contains one code, but the device doesn't accept it. This can happen if the printer has previously been reflashed or the settings have been changed through Embedded Web Server (EWS)In such cases, the label becomes invalid, and the current password is stored only in the device's memory.
Viewing your current password through the Control Panel
The most reliable way to find out the current password is to display the network configuration report directly from the buttons on the case HP 135wThe model is equipped with a small monochrome display and navigation keys, allowing you to navigate the menu without connecting to a computer. First, make sure the device is turned on and in standby mode.
The procedure for obtaining a report is as follows:
- 🖨️ Click the button
Menu(or the button with the gear/list icon) on the control panel. - 🔍 Using the navigation arrows, find the item Network or Network and confirm your choice.
- 📄 Select the option in the submenu
Print Report(Print report) or Config Page. - ✅ Press the confirmation button (usually this is the central button with the OK icon).
After printing the page, find the section Wi-Fi Direct. It will show the network name (SSID) and the current PIN codePlease note that if Wi-Fi Direct is disabled, the report may show the value Off or a dash. In this case, you must first activate the wireless module through the same menu.
There's also a quick way to check the status via the LED indicators. If you hold down the wireless button for 5-10 seconds, the printer may print a short report or change the LED blinking pattern to indicate the connection status. However, the full configuration report provides the most comprehensive information on all network parameters, including the IP address and subnet mask.

Reset network settings to factory defaults
If the password was changed manually and is lost, the only solution is to reset the network settings. This operation will restore the parameters Wi-Fi Direct And TCP/IP To its out-of-the-box state, including restoring the factory PIN code indicated on the sticker. It's important to understand that this action doesn't affect the device's settings, such as paper size or energy saving, but it will disconnect all current network connections.
To perform a reset on the model HP Laser 135w follow the following sequence of actions:
- Press and hold the button Wireless (antenna icon) and a button Cancel (cross icon) at the same time.
- Keep them pressed for 5-7 seconds until the power indicator starts flashing.
- Release the buttons. The printer will restart the network module.
After rebooting, the network settings will be reset. You can now use the code on the back sticker to connect. If you need to completely reset all device settings (hard reset), the procedure may vary and often requires turning on the printer while holding a specific key combination. However, resetting only the network card is sufficient to resolve Wi-Fi issues.
⚠️ Note: After resetting your network settings, all computers and smartphones will lose connection to the printer. You will need to reconfigure the connection on each device using the restored factory password.
In some corporate environments, administrators block the ability to reset the device via the control panel. If this method doesn't work, access to the menu may be restricted by an administrator password. In this case, the only solution is to reset the device via the web interface (if you know the IP address and the administrator's login/password), or to reflash the device.
Using the HP Smart app to set up
Modern setup methods involve the use of a mobile app. HP SmartThis software automatically scans the network and detects printers that are ready for pairing. If your HP 135w If it is in setup mode (wireless indicator is flashing), the app may offer to connect it without manually entering a PIN, using Bluetooth Low Energy for the initial data transfer.
The setup process through the app looks like this:
- 📲 Download and install the app HP Smart to a smartphone (iOS or Android).
- 📶 Turn on Bluetooth and geolocation on your phone.
- ➕ Click the "Add Printer" button or the plus icon in the app.
- 🔗 Follow the on-screen instructions to transfer your Wi-Fi network password to the printer.

What should I do if HP Smart doesn't see my printer?
Make sure your phone is connected to the same Wi-Fi network (2.4 GHz) as the printer. Some routers separate 2.4 and 5 GHz networks, and the printer may not be visible on the guest network or 5 GHz network. Try temporarily disabling your smartphone's mobile data.
Table of typical problems and solutions
Even with the correct password, users may encounter connection errors. Below is a table listing the most common connection issues. HP 135w over a wireless network and how to fix them.
| Problem | Possible cause | Solution |
|---|---|---|
| The password request keeps appearing. | Incorrect PIN or network change | Remove the device from the Wi-Fi list on your phone and add it again |
| The printer was not found in the network list. | The Wi-Fi Direct module is disabled | Print a configuration report and check the Wireless Direct status |
| Error: "Failed to connect" | Weak signal or interference | Move closer to the router and check the operation at 2.4 GHz. |
| Password not accepted | CapsLock layout or language is enabled | Enter the code carefully, checking the case and keyboard language |
Particular attention should be paid to the frequency range. Model HP 135w supports only the standard 802.11 b/g/n On the 2.4 GHz frequency. If your router only broadcasts a 5 GHz network or uses "5 GHz Only" mode, the printer will not be able to see the network. You need to ensure that legacy device support is enabled on your router or that a separate 2.4 GHz network has been created.
Setting up Wi-Fi Direct and changing the PIN
Function Wi-Fi Direct Creates a direct access point between the printer and your device, bypassing the router. This is convenient for quick printing from guests' phones or when the main internet connection is overloaded.

To change your PIN code, follow these steps:
- Open a web browser on a computer connected to the same network as the printer.
- In the address bar, enter the printer's IP address (you can find it in the configuration report).
- Go to the tab Networking -> Wireless Direct.
- In the field
Wi-Fi Direct PasswordEnter a new value and save the changes.
After changing the password, all previously connected devices will be disconnected. You will need to enter the new code on each smartphone or tablet. It is recommended to use complex combinations if the printer is located in a busy office to prevent unauthorized printing.
⚠️ Note: The web configurator (EWS) interface may vary depending on the firmware version. If you can't find the desired option, check for firmware updates on the manufacturer's official website.
Remember that a complex password increases security, but it also makes life more difficult. Write down your new password in a safe place or use a password manager. A forgotten password can only be removed by a full network reset, as described in the previous sections.
