Modern laser multifunctional devices are no longer bulky boxes that require mandatory cable connections. Model HP Laser MFP 135w This compact solution is ideal for homes and small offices where wireless printing has become a standard convenience. Eliminating the need for a USB cable from the computer to the printer frees up space and allows the device to be placed anywhere in the room with wireless coverage.
However, the initial setup wireless interface This interface often presents difficulties for users accustomed to simpler devices. Unlike inkjet models, it lacks a color touchscreen, and is controlled via a monochrome display and a limited set of buttons. This interface feature requires a clear understanding of the sequence of actions to successfully integrate the device into a local network.
In this guide, we'll cover all available connection methods in detail, from automatic pairing to manual setup via a computer. You'll learn how to correctly interpret blinking indicators and what steps to take if the router doesn't detect the printer. Proper setup will ensure stable operation of the device and access to document scanning over the network from any connected device.
Preparing the device and checking router compatibility
Before beginning the software setup, ensure the hardware is physically ready. Ensure the cartridge is installed and the protective tape is removed from all internal components. The printer should be plugged into a power outlet and located within a strong signal range, ideally no more than 5-7 meters from the router for the initial setup.
The frequency of the wireless network is critically important. Model HP Laser MFP 135w supports the standard 802.11b/g/n, which means working exclusively in the range 2.4 GHzIf your router only broadcasts at 5 GHz or uses the "5 GHz Only" mode, the device simply won't detect the signal.
⚠️ Note: In modern dual-band routers, the 2.4 GHz and 5 GHz networks may be combined (Smart Connect feature). If the printer fails to connect, try temporarily separating the networks in the router settings by giving them different names (SSIDs), and then connect the MFP to the 2.4 GHz network.
It's also a good idea to know your Wi-Fi network password in advance. Unlike smartphones, the printer can't ask for the password from already connected Android or iOS devices without using special data transfer protocols. Write down the password or keep it handy, as entering characters using the device's buttons can be difficult.
WPS method: the fastest way to connect
Technology WPS (Wi-Fi Protected Setup) Allows you to connect devices without entering a password, simply by pressing a button. This is the easiest method if your router has a physical WPS button or a similar feature in the web interface. The process takes less than a minute and doesn't require a computer.
To perform this method, press and hold the wireless button on the printer control panel. HP Laser MFP 135w For a few seconds, until the indicator light starts flashing. Then, within 2 minutes, press the WPS button on your router. If the connection is successful, the Wi-Fi indicator on the printer will turn solid.
It's worth noting that the WPS method isn't always reliable on networks with high bandwidth usage. If the first attempt fails, wait a minute and try again. In rare cases, older routers may require a PIN code, which can be found on a sticker on the back of the device, although modern security systems often block this method.
Setup via USB cable and software
The most reliable way to ensure that all network parameters (including complex passwords and hidden SSIDs) are transmitted is to use a temporary USB connection. To do this, you'll need a USB Type-B cable (with a square connector), which is usually included, and a computer running Windows or macOS.
First, you need to download the full package of drivers and utilities from the manufacturer's official website. Don't use the disc that came with the box, as the software versions on them are often outdated. During installation, select the "Wireless" connection type and follow the installation wizard. The program will prompt you to connect a cable to transfer the Wi-Fi settings.
☑️ USB Connection Checklist
After the software confirms successful setup, you can disconnect the USB cable. The printer will save the network settings in its memory and automatically connect to the router each time it's turned on. This method is especially useful if your network name contains special characters or Cyrillic characters that are difficult to enter manually.
Manual setup via control panel (SSID and password)
If using a cable is not possible and WPS does not work, you will have to use the device's menu. On the panel HP Laser MFP 135w Press the wireless network setup button (the antenna icon). The indicator will begin flashing, indicating that you're in search mode.
Next, press the Continue button (the large button with the triangle). The printer will begin printing a configuration report or simply enter connection standby mode. However, manual network setup often requires a button combination. Press and hold the Wireless button and the Cancel button (the cross) simultaneously for 3 seconds. This will enter setup mode.
In this mode, the device can create its own access point HP-Setup-135wBy connecting to it from your phone or laptop, you'll be taken to the printer's web interface, where you can select your home network from the list of available networks and enter the password. This is a more complex, but universal, method.
⚠️ Important: When entering a password through the web interface or control panel, ensure that the letters are capitalized. Even a single character error will cause the printer to repeatedly attempt to connect but will never receive an IP address.
Using the HP Smart app for mobile devices
Smartphone owners can use the app HP Smart, available for iOS and Android. This modern method is gradually replacing the need for a PC. The app automatically detects new HP devices within Bluetooth and Wi-Fi range.
Launch the app, register (or sign in), and click "Add Printer." Follow the on-screen instructions. The app will ask you to turn on Bluetooth on your phone and bring it close to the printer. Once detected, HP Smart will transfer your current Wi-Fi network settings directly to the device.
What to do if Bluetooth won't turn on?
Make sure the HP Smart app has permission to use location and Bluetooth. On Android, scanning devices without these permissions may not work due to security restrictions.
The advantage of this method is the ability to immediately test prints and scan documents directly from your phone. Furthermore, the app allows you to check the signal strength and, if necessary, reconfigure the connection if you move the router to another room.
Indicator table and problem diagnostics
Understanding the status of the indicators on the panel HP Laser MFP 135w — the key to quick diagnostics. The device communicates its status through a combination of steady lights and blinking patterns on the wireless button.
| Wi-Fi indicator status | Meaning | Action |
|---|---|---|
| Turned off | Wireless connection is disabled | Press the Wi-Fi button to turn it on |
| Blinks slowly | Setup mode or network search | Start the connection procedure (WPS or USB) |
| Flashing quickly | Connection error or signal loss | Check the password and distance to the router |
| It's on constantly | Successful connection to the network | You can start printing documents. |
If the indicator light flashes rapidly and remains steady for a long time, the password or encryption type is likely incorrect. HP 135w series printers work best with the security standard WPA2-Personal (AES)Using legacy WEP or mixed mode WPA/WPA2 may cause instability.
The problem may also lie in your router's DHCP settings. Make sure MAC address filtering isn't enabled on your router, which could block new devices. You can find your printer's address by printing a network configuration report (usually using a key combination or menu).
Frequently Asked Questions (FAQ)
Can the HP Laser MFP 135w be connected to a 5GHz network?
No, this model is equipped with a Wi-Fi module that operates exclusively in the 2.4 GHz band. To connect to a dual-band router, ensure that the 2.4 GHz network is active and has a separate name (SSID), or that the router correctly processes requests from older devices in mixed mode.
The printer stopped responding to network traffic after changing the router. What should I do?
When you change your router, your network name and password change. You'll need to reset your printer's network settings (usually by holding down the Wi-Fi button and the Cancel button) and reconnect using one of the methods described above so the device "remembers" the new hardware settings.
