How to connect the HP Laser 135w MFP to a Wi-Fi router

Multifunctional device HP Laser 135w It's one of the most popular compact solutions for small offices and home use. Its key advantage over the basic 135a model is its built-in wireless module, eliminating the need to run extra cables across the room. However, initial network setup often raises questions for first-time users, as the device lacks a full touchscreen for password entry.

The process of integrating a printer into a local network requires several steps to be followed sequentially, which may vary depending on the operating system of your computer or smartphone. Wireless connection Provides flexibility in device placement, allowing you to print documents from any device within the router's coverage area. It's important to understand that reliable operation directly depends on the accuracy of the entered data and the signal quality.

In this guide, we'll cover all current methods for activating the communication module, including using the WPS button, setting up via a USB cable, and using a mobile app. We'll also cover common errors that may occur when attempting synchronization and offer quick fixes without calling a service center.

Preparing to set up a wireless network

Before you begin configuration, you must ensure that all basic requirements are met. Router The printer must be turned on and transmitting a signal, and the printer itself must be loaded with toner and ready to use. If you plan to use a laptop or PC for initial setup, make sure it is connected to the same Wi-Fi network to which you want to connect the MFP.

Pay attention to the indicators on the control panel. The wireless button typically flashes blue when the device is waiting to connect, or stays solid when successfully activated. To start using the device, press and hold the antenna button for a few seconds until the indicator light starts flashing.

⚠️ Important: Make sure your router is broadcasting in the 2.4 GHz band. Many printer models, including HP Laser 135w, do not support the 5 GHz frequency, and attempting to connect to such a network will result in an error.

It's also recommended to know your Wi-Fi network password in advance if it's not saved on the devices you'll be using for setup. In some cases, you may need to temporarily use a USB cable to transfer network settings from your computer to the printer.

Connection method via WPS (Wi-Fi Protected Setup)

The fastest way to set up a connection is to use WPS technology, if your router supports it. This method allows you to transfer network information automatically, without having to manually enter a complex password on your computer keyboard.

To use this method, press the WPS button on your router. It's usually located on the back or side. After pressing it, you have about two minutes to activate the network search on the printer.

  • 📡 Press and hold the wireless button on the panel HP Laser 135w until the indicator starts flashing.
  • 🔌 Make sure the printer is in close proximity to the router (no more than 1-2 meters) during the pairing process.
  • ✅ Wait until the Wi-Fi indicator on the printer turns solid blue, indicating a successful connection.

If the indicator continues to flash or turns orange, the connection is not established. In this case, try repeating the procedure, making sure MAC address filtering is not enabled on the router.

Setup via USB cable and HP Smart

If the automatic connection fails, the most reliable option is to use a temporary USB connection. For this, you will need a USB 2.0 cable with Type-A and Type-B connectors (a standard printer cable).

First, connect the printer to your computer via USB. Then, launch the app on your PC or smartphone. HP Smart Or install the full driver package from the official website. The program will automatically detect the connected device and prompt you to set up a wireless network.

During the installation process, the program will ask if you want to set the printer to wireless mode. Accept the prompt, and the software will automatically transfer the network credentials (login and password) to the device. After confirming successful data transfer, you can disconnect the cable.

It's important to note that when using this method, the computer and printer must be on the same subnet. If you have a complex corporate network with multiple VLANs, configuration may require the involvement of a system administrator.

Using the HP Smart mobile app

HP has developed a convenient application for smartphone and tablet users. HP Smart, available for iOS and Android. It allows for on-the-fly setup, using the device's Bluetooth channel for initial data exchange.

Launch the app and tap the plus sign to add a new printer. The system will ask you to enable Bluetooth on your phone and allow location access, as this is a requirement for scanning Wi-Fi networks in modern versions of Android.

⚠️ Note: On Android 10 and above, the app may request location access permission. Without this permission, scanning for available Wi-Fi networks for the printer will be blocked by the OS security system.

Follow the on-screen instructions: the app will find the printer, prompt you to select your home network from the list, and enter the password. After that mobile device will transfer the settings to the MFP, and it will appear in the list of available devices for printing.

What should I do if the app doesn't see the printer?

Make sure the printer is in setup mode (the Wi-Fi button is blinking). If the light is solid, press and hold the wireless button and the cancel button simultaneously for 3 seconds to reset the network settings.

Network status indicator table

Understanding the signals the control panel emits greatly simplifies problem diagnosis. Indicators can indicate connection status, errors, or operating modes.

Indicator status Meaning Action
Turned off Wireless connection is disabled Press the Wi-Fi button to turn it on
Flashing blue Setup Mode / Network Search Start the connection procedure via software
It's blue Successful connection to the network You can start printing.
Flashing orange Connection error or failure Check your password or reset your network settings.

If the indicator light is orange, this often indicates an incorrect password or a weak signal. In such cases, it's helpful to move the printer closer to the router and try again.

Reset network settings to factory defaults

In situations where the printer has "remembered" incorrect data or stopped responding to commands, a full network reset may be necessary. This will return the Wi-Fi module to its original state, as it was when it was first turned on.

To perform a reset on the control panel HP Laser 135w You need to simultaneously press and hold two buttons: the wireless button and the cancel button (the cross). Hold them for about 3-5 seconds until all the indicators flash simultaneously.

  • 🔄 After the reset, the Wi-Fi indicator should start blinking blue slowly.
  • 📶 The printer will create a direct Wi-Fi access point (Wi-Fi Direct) for the initial configuration, if supported by the mode.
  • 🗑️ All saved passwords and IP address settings will be deleted from the device's memory.

This procedure is safe and does not affect print quality settings or the page counter, it only affects the communication module.

Common problems and their solutions

Even when following the instructions correctly, users may encounter a number of difficulties. Often, the problem lies in the router's security settings, such as AP client isolation or a hidden SSID.

If your computer can't see your printer on the network, even though both devices are connected to the same router, check if your firewall is blocking the connection. Also, make sure your computer and printer have the latest drivers and firmware.

⚠️ Note: Software and firmware interfaces are subject to update. If the menu items described differ, please refer to the documentation on the manufacturer's official website for your software version.

If you experience persistent connection interruptions, try statically assigning the printer's IP address in your router settings. This will prevent the device from receiving a new address and the computer from losing connection.
