Model HP Laser MFP 135wr It's one of the most popular compact solutions for small businesses and home use, offering printing, scanning, and copying functions in a single unit. However, initial wireless connection setup often raises questions for users new to printer network protocols.
In this article, we will go through all the steps of connecting a device to your local network in detail, and we will look at how the utility works. HP Smart and alternative setup methods via USB cable. You'll learn how to avoid common router frequency band errors and how to ensure stable printer operation even with a large number of connected devices.
Proper network configuration will allow you to not only print from any device, but also set up scanning to cloud storage or email. The key to successful setup is that the router supports the 2.4 GHz standard, as this model does not work with 5 GHz networks. Let's move on to preparing the equipment before starting the procedure.
Preparatory stage and network requirements
Before you begin software configuration, you must ensure that your network environment meets the device's technical requirements. Series printers Laser MFP They are equipped with a wireless module, which has its limitations compared to modern smartphones, primarily in terms of frequency range.
Most modern routers operate in two ranges: 2.4 GHz and 5 GHz Model HP Laser MFP 135wr supports only the standard 802.11 b/g/n in the 2.4 GHz band. If your router only broadcasts in the 5 GHz band or the network names (SSIDs) for different bands are combined into one, you may have difficulty detecting your device.
⚠️ Attention: If your router uses the "Smart Connect" feature (combining the 2.4GHz and 5GHz network names), try temporarily separating them in the router settings or create a guest network for the 2.4GHz band only to ensure successful pairing.
You'll also need to know your Wi-Fi network password. Make sure you enter it correctly, including capitalization, as even a single character error will result in an endless loop of connection attempts. Place the printer no more than 1-2 meters from the router during setup to ensure maximum signal strength.
- 📶 Check that your router is broadcasting in the 2.4 GHz band.
- 🔑 Prepare the exact password for your Wi-Fi network (no typos).
- 📱 Charge your smartphone or prepare a laptop with internet access.
- 🔌 Make sure the printer is plugged in and in the ready state.
Reset network settings and activate setup mode
If the printer has been used before or you purchased a used device, it may still have old network profiles that will conflict with the new configuration. To initiate a clean configuration, you must reset the network settings to factory defaults. This will ensure that the network module will begin searching for a new network.
On the control panel HP Laser MFP 135wr Locate the wireless button or the settings button. Depending on your firmware version, you may need to press and hold the wireless button and the cancel button (the cross) simultaneously for a few seconds. The wireless indicator should start flashing blue, indicating that you're in setup mode.
What do the Wi-Fi lights on the panel mean?
The indicator light is flashing blue: setup mode (the device is ready to connect). The indicator light is solid blue: connected to the network. The indicator light is solid orange or flashing orange: connection error or low signal strength.
An alternative way to activate the setup mode is to use the menu on the small display. Press the menu or setup button until the text appears on the screen. Network or an image of an antenna. Using the navigation buttons, select the network reset option. After the module reboots, the printer will create its own access point with a name like HP-Setup-135w, which can be connected directly from the phone for initial configuration.
Using the HP Smart app to set up
The easiest and manufacturer-recommended way to connect is to use a mobile application. HP Smart. Available for iOS and Android operating systems, as well as a desktop app for Windows and macOS, this method automatically detects the printer on the network and guides you through all the configuration steps in a visual interface.

- 🔍 Click "Add Printer" and wait for the device to be detected.
- 🔐 Enter your Wi-Fi network password when prompted by the app.
- ✅ Wait for a message about successful connection and driver installation.
Connection via USB cable and installation wizard
In cases where wireless setup via the app fails (for example, due to corporate network security or a hidden SSID), the most reliable method is to use a USB cable. For this, you'll need a USB Type-B cable (with a square connector), which is often included in the package, or a standard USB 2.0 A-B cable.
Visit the official HP support site and download the full package of drivers and software for your model. 135wrRun the installer on your computer. When prompted for a connection type, select "Wireless Connection," but in the next step, specify that you want to use a USB cable for initial setup.
Connect the cable between your computer and the printer. The setup wizard will automatically transfer your computer's network settings to the printer. Important: At this point, the computer and printer must be within the same Wi-Fi range, even though the connection is via a cable. After receiving the settings, the printer will disconnect the USB data connection and switch to the wireless module.
☑️ USB Connection Checklist
After successfully transferring the parameters, the installer will prompt you to disconnect the USB cable. The printer should automatically switch to network mode, and the Wi-Fi indicator will glow solid blue. If this doesn't happen, check the device's status in the operating system's printer list.
Setup via WPS (Wi-Fi Protected Setup)
If your wireless router supports the technology WPSThe connection process can be significantly simplified by avoiding manual password entry. This method is ideal for users who don't want to use mobile apps or search for drivers. WPS allows devices to exchange encryption keys automatically through physical authentication.
Press and hold the WPS button on your router for 2-3 seconds until the WPS indicator on the router starts flashing. Then, within 2 minutes, press and hold the wireless button on the control panel. HP Laser MFP 135wr until the power and wireless indicators start blinking simultaneously.
⚠️ Attention: The WPS method will not work if WPS is disabled in the router's security settings or if the encryption type used is not supported by this protocol. It also won't work if the network's SSID is hidden.
The printer will automatically detect the router and establish a connection. This process may take up to 2 minutes. If the wireless indicator turns blue, the setup was successful. Otherwise, repeat the procedure, ensuring you press the buttons within the two-minute interval.
Diagnostics and static IP address
After a successful connection, we recommend verifying the connection is stable and, if necessary, assigning a permanent IP address to the printer. Dynamic addressing (DHCP) is convenient, but if the router reboots, the printer's address may change, resulting in loss of connection to the computer if the driver was installed using the old IP address.
To check the status, print a network configuration report. On the printer control panel, press the Reports button or use the menu button combination to select Network ConfigFind the section on the printed sheet. IPv4. The current IP address, subnet mask, and gateway will be displayed here.
To assign a static IP, open a browser on your computer and enter the printer's current IP address (e.g., 192.168.1.55). The built-in web interface (EWS) will open. Go to the tab Network -> IPv4Select the "Manual" option and enter an address that is outside your router's DHCP range but in the same subnet.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | The printer's unique address on the network | 192.168.1.150 |
| Subnet Mask | Subnet mask (determines the size of the network) | 255.255.255.0 |
| Gateway | Your router's address (gateway) | 192.168.1.1 |
| DNS Server | Name server (can use gateway) | 192.168.1.1 |
Solving common connection problems
Even if you follow all the instructions, technical difficulties may arise. Often, the problem lies with antivirus software or Windows Firewall, which are blocking the detection of new devices on the network. Try temporarily disabling the firewall during setup, and then add the printer to the exceptions.
Another common cause is the use of Wi-Fi extenders (repeaters). Printers HP Laser MFP 135wr Some repeater models may not work correctly, especially if they change the MAC address or use different encryption standards. In this case, it's best to connect the printer directly to the main router.
It's also worth paying attention to updating your device's firmware. Outdated software may contain bugs that interfere with the stable operation of the Wi-Fi module. This can be done via the web interface or app. HP Smart Check for updates. The update process may take 10-15 minutes, during which time the printer will be unusable.
Why won't my printer connect to the 5GHz network?
Wireless communication module in HP Laser MFP 135wr The printer doesn't physically support the 5 GHz frequency. It only operates in the 2.4 GHz band. If your router broadcasts networks with the same name (SSID) for both bands, try separating them in the router settings by giving the 2.4 GHz network a unique name (e.g., MyWiFi_24), and connect the printer to that network.
What to do if the orange Wi-Fi light is on?
An orange light usually indicates a connection error or a weak signal. Try moving the printer closer to the router. If that doesn't help, reset the network settings and try re-entering the password, checking your keyboard layout and capitalization.
Can I connect a printer to a guest Wi-Fi network?
Yes, this is possible and often even preferable for security reasons. A guest network isolates devices from each other but still allows them to access the internet. The main thing is that the computer you're printing from is also connected to the same guest network, as direct printing is only possible within the same subnet.
How to find out the IP address of a printer without printing a report?
On a Windows computer, open Control Panel -> Devices and Printers. Find your HP Laser MFP 135wr, right-click it, and select Printer Properties. Go to the Web Services or Ports tab—the IP address is often listed there. You can also use the command ping on the command line, if the device hostname is known.
Do Wi-Fi settings reset when the printer is turned off?
No, wireless network settings are saved in the device's non-volatile memory. After turning the printer off and on again, it will automatically attempt to connect to the previously saved network. A reset occurs only when performing a special procedure called "Restore Factory Network Defaults."
