Multifunctional device HP Laser MFP 135wr It's a popular solution for small offices and home use due to its compact size and wireless printing capabilities. However, initial Wi-Fi connection setup often presents difficulties for users unfamiliar with the network protocols of MFPs. Unlike more modern models with touchscreens, setup is accomplished using a combination of buttons on the control panel and specialized software.
The key to successfully integrating a printer into a local network is following the correct sequence of steps when installing drivers. Wireless connection Requires the computer and printer to be within range of the router's signal. Incorrect initial configuration may result in the device appearing offline or not being detected by the system at all.
In this guide, we'll cover every step of the connection process, from preparing the equipment to setting up a static IP address for stable operation. You'll learn how to avoid common password errors and why it's sometimes necessary to use a temporary USB connection for initial network configuration.
Preparing equipment and checking network compatibility
Before you begin software configuration, you need to make sure that you are physically ready MFP 135wr The device must be plugged into a power outlet, and the cartridge and paper must be loaded into the tray. Pay special attention to the indicators on the control panel: the wireless button should be blinking, indicating that it's in standby mode.
A critical parameter is the operating frequency of your Wi-Fi router. Model 135wr supports only the standard 2.4 GHz and does not see networks operating exclusively in the range 5 GHzIf your router broadcasts a single network (Dual Band), there are usually no problems, but when splitting into different SSIDs, you must select a network ending in "2.4G" or something similar.
⚠️ Attention: Some corporate networks use hidden SSIDs or complex encryption methods (Enterprise), which this MFP may not support. For home setups, use the standard WPA2-Personal encryption.
Also, make sure the distance between the router and printer during setup doesn't exceed a few meters. Walls and metal structures can significantly weaken the signal, causing a timeout when attempting to establish a handshake between the devices.
Resetting the printer's network settings before installation
If the device was previously used on a different network or the setup was incorrect, we recommend resetting the network settings. This will clear saved profiles and allow you to start the configuration from scratch. HP Laser 135w The reset procedure is performed through a key combination on the panel.
Press and hold the Wireless button (antenna icon) and the Cancel button (red cross) simultaneously for 5 seconds. The lights will flash, confirming the reset. The printer will then reboot the network module, and the Wi-Fi light will begin flashing rapidly, entering network search mode.
- 📡 Make sure the Wi-Fi indicator is flashing blue - this means it is ready to pair.
- 🔌 Do not turn off the device's power during the reset process to avoid damaging the network module firmware.
- 🔄 If resetting doesn't help, try unplugging the printer for 30 seconds to fully discharge the capacitors.
☑️ Check before connection
Using WPS for a quick connection
The easiest way to connect HP MFP 135wr The easiest way to connect to the network is with WPS (Wi-Fi Protected Setup), if your router supports it. This eliminates the need to manually enter a password and potential typing errors. This method is ideal for users who don't want to install cumbersome software on their computer.
Press the WPS button on your router. Within 2 minutes, press and hold the wireless button on the printer until the light starts blinking. The devices will automatically exchange encryption keys, and the Wi-Fi light on the printer will turn solid, indicating a successful connection.
What to do if WPS doesn't work?
The WPS function may be disabled in the router settings or not supported by the provider. In this case, you must use the USB cable setup method or the WPS PIN software method, which is generated by pressing the Wi-Fi button on the printer (single press) and entering the code into the router interface.
It's worth noting that the WPS method is less secure according to some cybersecurity standards, as it uses a simplified key exchange protocol. For office environments with high data security requirements, manual configuration via an installation disk is preferable.
Setup via USB cable and software
The most reliable method to ensure that all necessary drivers and utilities are installed is to use the installation package. HP Smart or the full driver from the official website. Initial network setup will require temporarily connecting the printer to your computer via USB.
Download the full driver package for your model. 135wr From the official support website. Run the installer and follow the on-screen instructions. When prompted to select a connection type, select "Wireless Connection" and follow the prompts to transfer Wi-Fi settings from your computer to the printer via USB.
⚠️ Attention: When transferring network settings via USB, your antivirus or Windows Firewall may block the connection. We recommend temporarily disabling protection or allowing the application to access the network.
Once the settings are successfully transferred, the printer will disconnect from USB and attempt to connect to Wi-Fi. The installer will automatically detect the device on the network and complete the driver installation wirelessly. You can disconnect the cable immediately after the success message.
Troubleshooting driver and network visibility issues
A common problem after connecting is that the computer doesn't see the printer in the list of available devices. This may be due to the operating system and the printer being on different subnets or the wrong driver type being used. Windows 10/11 recommends using the "Class Driver" driver, but for full scanning functionality it is better to install the full package HP Full Feature Software.
Check the printer's IP address by printing a network configuration report. Press and hold the "Info" button (or the button combination specified in the manual) for 5 seconds. Compare the first three digits of the printer's IP address (e.g., 192.168.1.X) with your computer's IP address. If they are different (e.g., 192.168.0.X and 192.168.1.X), the devices are on different networks and will not see each other.
- 💻 Make sure that the "Private network" profile is selected in Windows network settings, not "Public."
- 🛡️ Check if your firewall is blocking the ports used by the printing protocol (usually 9100).
- 📶 Try temporarily disabling the VPN connection on your computer, as it may change your network gateway.
Setting up a static IP address for stability
For office use, it's critical that the printer's IP address doesn't change after a router reboot. If the address changes, computer drivers will no longer find the device. To avoid this, reserve the IP address in the router settings or enter a static IP directly in the printer's settings via the web interface.
Enter the printer's IP address into your browser's address bar (e.g. http://192.168.1.55). Go to the "Network" tab. Here you can disable DHCP and manually enter the address, gateway, and DNS. However, a more reliable method is to configure DHCP Reservation on the router itself using the printer's MAC address.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | The unique address of a device on the network | 192.168.1.200 |
| Subnet Mask | Subnet mask determines the size of the network | 255.255.255.0 |
| Gateway | Router (gateway) address | 192.168.1.1 |
| DNS Server | Name server (you can use a public one) | 8.8.8.8 |
⚠️ Note: When manually setting up a static IP, make sure the address you select is outside the router's DHCP pool range, otherwise an address conflict with another device may occur.
Frequently Asked Questions (FAQ)
Can the HP 135wr be connected to a 5GHz network?
No, model HP Laser MFP 135wr The printer is equipped with a Wi-Fi module that only supports the 802.11 b/g/n standard in the 2.4 GHz band. Connecting to a 5 GHz network is technically impossible. If your router is broadcasting two networks with the same name, try separating them in the router settings, giving the 2.4 GHz network a unique name, and connecting the printer to that network.
The printer prints but won't scan over the network. What's wrong?
To use network scanning (Scan to PC), simply installing the print driver is not enough. You must install the full software package. HP Scan or utility HP Smart, which registers the device in the system as a scanner. Also, make sure that in the settings
