Setting up a wireless connection for office equipment often turns into a test of patience, especially when it comes to specific models such as HP Laser MFP 135wThis compact device combines the functions of a printer, scanner, and copier, but lacks the familiar color touchscreen, making menu navigation difficult. Users often encounter difficulties when trying to integrate the device with their home network, as they don't understand the logic behind the indicators and buttons on the control panel.
However, knowing the exact sequence of actions and software features can help you avoid spending hours searching for a solution online. Wireless printing Provides access to convenient features, such as scanning to PDF directly to your computer or printing documents from your smartphone. In this article, we'll cover every step of the connection process, from preparing the equipment to fine-tuning the network settings for stable operation.
It's important to understand that the success of the operation depends not only on the correct password entered, but also on the compatibility of your router's security protocols. Modern encryption standards may conflict with the printing modules built into budget models. Therefore, before beginning the active setup phase, we recommend reviewing the technical requirements and ensuring that your network equipment is functioning correctly.
Equipment preparation and compatibility testing
The first step is to physically prepare the device for wireless operation. Make sure that HP Laser MFP 135w Plugged in and ready to use. Although the model supports WiFi, initial setup often requires either a USB cable for a temporary connection to a PC or using the WPS method if your router supports it. Check that the power indicator is lit and there are no flashing errors on the display.
Checking the wireless network frequency is critical. The communication module in this MFP model operates exclusively in the range 2.4 GHzIf your router only broadcasts the 5 GHz network or uses "5 GHz only" mode for guests, the device simply won't see the access point. You need to access the router settings and ensure the 2.4 GHz network is active and has a separate name (SSID) or is merged with the main network.
⚠️ Note: If you're using a dual-band router with the "Smart Connect" feature (which combines the 2.4 GHz and 5 GHz network names), try temporarily separating them into different SSIDs. This often solves the problem of the printer not seeing the network, even though it works on other devices.
It's also a good idea to prepare your login information. Know your WiFi network password in advance. Pay attention to the letter case: the device treats the characters "A" and "a" differently. If your password uses special characters, make sure you know how to enter them using the buttons on the MFP's control panel, as there's no virtual keyboard in the usual format.
WPS method: quick connection without a computer
The easiest way to activate wireless connection — Using WPS (Wi-Fi Protected Setup) technology. This method allows you to transfer security settings automatically, eliminating the need to manually enter a long password using the navigation buttons. First, make sure your router has a physical WPS button or a corresponding function in the web interface.
On the MFP control panel, find the button with an antenna or WiFi icon. Press and hold it for a few seconds until the wireless network indicator starts blinking. Then, within two minutes, press the WPS button on the router. The device will automatically detect the network and attempt to establish a connection.
- 📶 Press and hold the WiFi button on the printer until the indicator light starts blinking.
- 🔌 Press the WPS button on the router within 2 minutes of activating the mode on the printer.
- ✅ Wait until the WiFi indicator on the MFP stops flashing and lights up steadily.
- 🖨️ Print a network configuration report to ensure that you have successfully connected and obtained an IP address.
If the indicator continues to flash or remains orange, the connection has failed. This may be due to a timeout or incorrect router security settings. In this case, it's worth switching to a more secure software setup method, which offers more control over the process.
Setup via HP Smart and USB cable
The most reliable method to ensure that all required components are installed is to use the utility HP Smart or a full driver package from the manufacturer's website. To do this, you'll need to temporarily connect the MFP to your computer via a USB cable. This cable may not be included with the device, so you'll often need to use a standard USB 2.0 Type A to Type B cable, which many users already have.
Download the latest driver from the official website, selecting your operating system. During installation, the program will prompt you to select a connection type. Select "Wireless Connection" or "Wi-Fi." The utility will automatically detect the device connected via USB and offer to reconfigure its network settings.
☑️ Check before installing the driver
During the setup process, the program will transfer your network's SSID and password to the printer. Once the data is successfully transferred, the software will prompt you to disconnect the USB cable. Don't ignore this step., as this is when the device switches to wireless. If you pull the cable out prematurely, the process may be interrupted.
After disconnecting the cable, the WiFi indicator should turn blue, indicating successful operation. The computer will automatically find the printer on the network using the new IP address. If this doesn't happen, check your firewall or antivirus software to see if it's blocking network device detection.
Manual setup via control panel
If you don't have a computer or USB cable handy, you can try setting up the network manually using only the buttons on the MFP. This process requires careful attention, as navigation is accomplished by cycling through the values using the arrow button and confirming with the OK button.
To enter the settings menu, press the gear button or hold the Cancel button until the wireless indicator lights up. In the "Network" or "Wireless" menu, select "WiFi Setup Wizard." The device will begin searching for available networks. Find your router's name in the list and press OK to select it.
What if your network is not on the list?
If your network is hidden (Hidden SSID), it won't appear in the list. You'll need to select "Enter New" or "Manual" and enter the network name manually, using the navigation buttons to select letters and numbers. This is a time-consuming process that requires precision.
Passwords are entered by selecting characters. The device's screen has limited display, so entering complex passwords may take time. Use the arrow keys to move the cursor and select the desired character from the available set. After entering the last character, press OK to confirm.
After confirmation, the device will attempt to connect. If the password is correct and the signal is strong enough, you'll see a "Connected" message or similar. If you see an "Authentication Failed" error, check the keyboard layout and capitalization of the characters you entered. Users often confuse the number "0" with the letter "O," which leads to authorization failure.
Diagnosing problems and printing a report
If the connection fails, you need to understand the cause of the failure. Built-in diagnostic system HP Laser MFP 135w Allows you to display a network status report. To do this, press and hold the wireless button or use a key combination (usually "Cancel" + "Wireless"; refer to the manual for your specific revision for the exact combination) until the page starts printing.
In the report, you're interested in the "Network Status" and "Connection Status" sections. The current IP address will be listed there. If the address begins with 169.254.x.x or equal 0.0.0.0, this means that the device has not received an address from the router. If the address looks like this 192.168.1.x or 10.0.0.x, then there is a physical connection, and the problem may be in the drivers on the computer.
| WiFi indicator status | Meaning | Action |
|---|---|---|
| Turned off | The wireless module is turned off | Press the WiFi button to turn it on |
| Flashing blue | Searching for a network or connecting process | Wait for completion or check your router |
| It's blue | Successful connection to the network | You can start printing and scanning |
| Flashing orange | Connection error or weak signal | Check the password and distance to the router |
The report may also indicate the cause of the error, such as "Invalid Security Type." This indicates that the router is using an encryption method not supported by the printer (e.g., WPA3 only). In this case, you should change the router's security settings to mixed WPA2/WPA3 mode or WPA2 only.
Remote control and mobile printing
Once WiFi is successfully set up, printing from smartphones and tablets becomes possible. Android and iOS devices use the technology HP Smart or built-in AirPrint support. Make sure your mobile device is connected to the same WiFi network as the printer.
The HP Smart app not only lets you print but also scan documents directly to the cloud or your phone's memory. The "Smart Tasks" feature automates routine tasks, such as scanning a contract and emailing it with one click. This significantly increases productivity.
- 📱 Download the HP Smart app from the AppStore or Google Play.
- 🔍 Click "Add Printer" and select your device from the list.
- 📄 Select a document or photo to print from your phone's gallery.
- ⚙️ Adjust the settings (black and white printing, number of copies) and click "Print".
⚠️ Please note: Mobile app features may vary depending on your region and operating system version. Some advanced settings are only available through the full PC driver.
Additionally, the device firmware can be updated via the web interface (EWS), accessible via the printer's IP address in a browser. Firmware update This is an important step, as manufacturers frequently release patches that improve the stability of the WiFi connection and add support for new security standards.
In conclusion, it is worth noting that the correct WiFi setup on HP Laser MFP 135w Requires careful attention to detail, especially the encryption type and signal frequency. Once you get past the initial configuration, the device will operate reliably, providing the convenience of wireless office equipment.
Why doesn't the printer see the WiFi network, even though the phone connects?
