How to set up Wi-Fi on the HP Laser MFP 135WR printer

Modern office and home tasks require maximum mobility, and wired equipment connections often become a limiting factor. Wireless printing allows you to place the device in any convenient place where there is an electrical outlet, without being tied to a desktop computer. Model HP Laser MFP 135wr is a popular solution due to its compact body and technology support Wi-Fi Direct.

The initial configuration process may seem complicated due to the lack of a full touchscreen, but it's quite straightforward. All you need is a little patience and an understanding of the steps. In this article, we'll cover all the details of the connection, from preparing the equipment to troubleshooting common errors that may arise along the way.

It is important to understand that the stability of work MFP The connection directly depends on the signal quality and the correctness of the entered parameters. Incorrectly configured frequency or encryption type can lead to constant connection drops. Let's look at how to avoid these problems and set up the system right the first time.

Preparatory stage before connection

Before proceeding with software setup, you need to make sure the hardware is physically ready. Make sure the printer HP Laser MFP 135wr Plugged into the network and located within a strong signal range. The distance to the router should not exceed reasonable limits, especially if there are load-bearing walls or metal structures between them that could block the signal.

Knowing your wireless network settings is critical. You need to know SSID (network name) and password for access. If you have a dual-band router broadcasting 2.4 GHz and 5 GHz networks, make sure you plan to connect to the band 2.4 GHz, since many budget printer models do not support the 5 GHz standard.

It's also worth checking the condition of the cartridges and whether there's paper in the tray. The printer should be in a ready state, not in deep sleep or error mode. If any alarm indicators are illuminated on the control panel, troubleshoot the hardware issue first.

⚠️ Important: Make sure AP Isolation is not enabled on your router. If it is enabled, devices on the Wi-Fi network will not be able to see the printer, and printing will be impossible, even if the connection is successful.

Resetting the printer's network settings

If the device was previously used on a different network or if configuration attempts were unsuccessful, we recommend resetting the network settings. This will clear saved profiles and return the network module to its original state. To do this, use the control panel. HP Laser MFP 135wr You need to press the wireless button and hold it for a few seconds until the indicators start flashing.

An alternative reset method can be performed through the menu, if available. Typically, this is a button combination described in the manual, but holding the Wi-Fi button is the most universal method for the series. LaserAfter the reset, the wireless indicator should flash, indicating that it is ready to pair.

Don't skip this step if you've purchased a used device or moved to a new office. Old configurations may conflict with the router's new security settings. A clean start eliminates many potential authentication errors.

Connecting via USB cable (WPS method is not supported)

Model 135wr doesn't support automatic configuration via the WPS button on the router, so the most reliable method is to use a USB cable for initial data transfer. You'll need a USB Type-B (printer) cable and a computer with an operating system installed. Windows or macOS.

First, download the full package of drivers and utilities from the manufacturer's official website. Avoid using the included discs, as the software versions on them are often outdated. Run the installer and wait until the program asks you to select a connection type.

Select the "Wireless Connection" or "Wi-Fi" option, even if the cable isn't connected yet. When the installer prompts you to connect the cable, connect your computer and printer. The program will automatically read your computer's current network settings and transfer them to the printer. This is the easiest way to forward the Wi-Fi password to your device without manually entering it.

Configuration via the control panel (WPS PIN)

If a cable isn't possible, you can use the PIN method. Press the wireless button on the printer's control panel to launch setup mode. The printer will print a report or display a code that must be entered into the router interface or a dedicated HP website.

This method requires access to your router's web interface. Find the WPS section and enter the PIN code displayed or printed by the printer. The router will then automatically transfer the network credentials to the device. MFP.

However, this method doesn't work with all routers, especially those provided by ISPs. If the router doesn't respond to the request or returns an error, revert to the USB cable method, as it's more stable for this series of devices.

What to do if WPS doesn't work?

The WPS function is often blocked by antivirus software or router security settings. In this case, using a USB cable for initial setup is the only reliable option for transferring Wi-Fi settings.

Using the HP Smart app for mobile printing

For smartphone and tablet users, configuration via a mobile app is available. HP SmartThis application is available for Android And iOSIt allows you not only to print documents, but also to perform initial printer setup without a computer.

Launch the app and tap "Add Printer." The app will find the device in pairing mode. Next, follow the on-screen instructions: the app will prompt you to select your Wi-Fi network and enter the password. Your smartphone will transfer this information directly to the printer via Bluetooth or a temporary hotspot.

Once successfully connected, you'll be able to scan documents directly to your phone and print them from any app. This turns HP Laser MFP 135wr into a full-fledged document digitization center.

⚠️ Important: When setting up via the mobile app, make sure your smartphone is connected to the Wi-Fi network (2.4 GHz) you want to connect the printer to. Switching between 2.4 and 5 GHz networks during setup may interrupt the process.

Network status indicator table

Understanding the indicator lights helps you quickly diagnose the connection status. Panel HP Laser MFP 135wr It is equipped with a minimalistic set of indicators, each of which carries important information.

Wi-Fi indicator status Meaning Action
Blinks slowly Setup mode / Waiting for connection Start the pairing procedure with your PC or phone
It's on constantly Successful connection to the network You can start printing.
Flashing quickly Connection error or signal loss Check the password and distance to the router
It doesn't burn. The wireless module is turned off Press the Wi-Fi button to activate

Pay attention to indicator combinations. For example, if the toner and Wi-Fi indicators are flashing simultaneously, this may indicate a critical firmware or cartridge compatibility error that is blocking network functions.

Solution and diagnostics

A common problem is when the computer "doesn't see" the printer on the network, even though the printer indicator light is solid. This could be due to Windows Firewall or antivirus settings. Try temporarily disabling protection and checking if the device is visible.

Another common issue is a change in the printer's IP address. If a static IP address isn't reserved in the router, the address may change after a reboot, causing the driver to lose connection with the device. In this case, reinstalling the printer through "Devices and Printers" with a new port may help.

If all else fails, perform a full network reset as described in section two and try connecting the device to a guest Wi-Fi network to rule out any issues with corporate security restrictions.

Why won't my printer connect to the 5GHz network?

Wi-Fi module in the model HP Laser MFP 135wr The printer only operates in the 2.4 GHz frequency range. It physically cannot see or connect to 5 GHz networks. You will need to switch your router to compatibility mode or create a separate 2.4 GHz network to connect the printer.

How to find out the IP address of a printer?

The easiest way is to print a network configuration report. Press and hold the Cancel button (the cross) or the Wireless button (depending on your firmware version) for 5-10 seconds until printing begins. The report will show your current IP address.

Is it possible to connect a printer to a hidden network (Hidden SSID)?

Yes, but only by manually entering the settings via a USB cable or HP utilities. The automatic network search will not detect a hidden SSID. You will need to manually enter the network name, strictly capitalizing.
