You'll learn how to correctly interpret the indicator lights and what to do if automatic connection fails.
To successfully complete the operation, you'll need to know your Wi-Fi network password and have a computer or mobile device handy. We'll cover the nuances of working with various operating systems and troubleshoot common errors that may arise during the hardware synchronization process.
Preparatory stage and equipment testing
Before you start making any changes to your network settings, make sure that your printer is HP Laser MFP 135w Plugged into a power outlet and ready to use. The device should be located within a strong signal range of your wireless router, as weak signal strength can cause connection drops or initial pairing failure. The distance to the access point should not exceed standard limits for the 2.4 GHz band.
It is important to prepare your local network authorization data in advance. You will need the exact network name (SSID) and an access password. Please note that this printer model, like most devices in this class, only supports a frequency range 2.4 GHzIf your router broadcasts networks with the same name for both the 2.4 GHz and 5 GHz bands, conflicts may occur, so it's recommended to temporarily separate them or ensure the correct band is prioritized.
⚠️ Important: Make sure your Wi-Fi password is case-sensitive and includes special characters. Even a single character error will prevent the printer from obtaining an IP address from the router.
Also, check that you have the necessary drivers on your computer. Although modern operating systems often automatically detect the device, for the MFP to function properly HP Laser MFP 135w It's best to download the full software package from the manufacturer's official website in advance. This ensures that after setting up Wi-Fi, you'll be able to not only print but also scan documents over the network.
Quick setup method via WPS button
The fastest way to establish a connection between the printer and the router is to use technology WPS (Wi-Fi Protected Setup). This method allows you to transfer network settings automatically, eliminating the need to manually enter a lengthy password on a device without a full-screen display. To implement this method, your router must support this feature, which is essential for the vast majority of modern equipment.
Find it on the front panel of your printer. HP Laser MFP 135w A button with a wireless antenna icon. A short press puts the device into network search mode, indicated by a blinking Wi-Fi indicator. After this, you must press the WPS button on your router within two minutes. On some router models, this button may be combined with the Wi-Fi power button or require holding for several seconds.
- 📶 Press the Wireless button on the printer – the indicator light will start flashing.
- 🔘 Activate WPS mode on your router physically or via the web interface.
- ⏳ Wait about a minute until the indicator on the printer lights up steadily.
- ✅ A successful connection is confirmed by the wireless network indicator glowing continuously.
If the indicator continues to flash or lights intermittently, pairing has failed. This may be due to a timeout (the WPS window typically remains open for 2 minutes) or incompatible encryption protocols. In this case, we recommend switching to a more secure setup method using a USB cable, which allows for forced settings transfer.
Setting up Wi-Fi via USB cable (Recommended method)
The most stable result is achieved by using a USB cable for initial configuration. This method allows the computer to directly communicate with the printer. HP Laser MFP 135w Your network settings. You'll need a USB 2.0 Type-A to Type-B cable, which is often included in the kit, but may require a separate purchase, as it's not included in some regions.
To begin, connect the printer to your computer via USB and turn it on. Run the driver installer, which you previously downloaded from the official HP website. During the installation, the program will prompt you to select a connection type. Select "Wireless" or "Wi-Fi," even though the device is currently connected via a cable. The installer will automatically read your computer's current network settings and transfer them to the MFP's memory.
☑️ USB Connection Checklist
During the installation process, you may be prompted to temporarily disconnect the USB cable. Follow the on-screen instructions: typically, you should disconnect the cable after the program reports that the network settings have been successfully transferred. After this, the printer will automatically attempt to connect to the network using the received data. The Wi-Fi indicator on the device should stop blinking and remain lit.
| Wi-Fi indicator | State | Meaning |
|---|---|---|
| Turned off | It doesn't burn. | The wireless module is turned off |
| Flashing | 1 second on/1 second off | Setup mode or connection error |
| It's on constantly | Blue/Green | Successful connection to the network |
| Blinks slowly | Rare outbreaks | The process of obtaining an IP address is in progress. |
After the parameters have been successfully transferred, you can disconnect the USB cable. Now your HP Laser MFP 135w is a full member of the local network. The computer used for setup must also be connected to the same Wi-Fi network for the system to detect the printer.
Using the HP Smart app for mobile devices
HP has developed an application for smartphone and tablet users. HP Smart, which significantly simplifies the setup process. This method is ideal if you don't have a computer with a USB port nearby. The app is available for iOS and Android and allows you to perform initial printer setup using your smartphone's Bluetooth connection.
Download and install the application HP Smart From the App Store or Google Play. Make sure Bluetooth and location services (GPS) are enabled on your phone, as these permissions are required to search for the printer in setup mode. Turn on the printer and press the wireless button on its panel to activate pairing mode. In the app, tap "Add Printer" and follow the on-screen instructions.
The app will automatically offer to transfer the Wi-Fi settings your smartphone is connected to to the printer. HP Laser MFP 135wYou may be asked to confirm the action or enter your network password if it isn't stored on your phone. This method is especially convenient because after setup, you immediately have access to scanning and printing photos directly from your mobile device.
What should I do if the app doesn't see the printer?
Make sure the printer is in setup mode (the Wi-Fi light is blinking). If the light is steady, the printer is already connected to another network. In this case, press and hold the wireless button on the printer for 3-5 seconds until the lights start blinking, resetting the network settings. Then, try searching again in the app.
Solving common connection problems
Even if all instructions are followed, situations may arise when the printer HP Laser MFP 135w refuses to connect to the network. One common reason is hiding the network name (SSID) router. If your network is hidden, the printer won't be able to find it in the list of available networks. In this case, you'll need to either temporarily enable network name display in your router settings or use the WPS method, which doesn't require network visibility.
Another issue lies in the router's security settings. HP printers may not work correctly with certain encryption modes or if IP filtering is enabled. MAC addressesCheck the list of connected devices in the router's admin panel. If you see a device with a name containing "HP" or "Print" but the connection status is "Limited," try disabling MAC address filtering or whitelisting the printer's address.
- 🔄 Reset settings: Press and hold the Wi-Fi button and the Cancel button (X) simultaneously for 3 seconds. This will restore factory network settings.
- 📡 Frequency range: Make sure your router isn't set to operate exclusively in 5 GHz mode. The printer won't see that network.
- 🔌 Reboot: Turn off the router and printer. Turn on the router, wait until it fully boots up, then turn on the printer.
⚠️ Note: The router setup interface and menu item names may vary depending on the model and firmware version. If you are unsure, consult the documentation from your internet service provider or router manufacturer to avoid disrupting your home network.
It's also worth paying attention to the number of connected clients. Some budget routers have a limit on the number of simultaneously connected devices. If the limit is reached, a new device, in this case a printer, will be needed. HP Laser MFP 135w, won't receive an IP address. Free up a slot by disabling unused devices or expand your network's capabilities.
Printing a network configuration report
For in-depth troubleshooting or simply to get information about the current connection status, it's useful to print a network configuration report. This document contains technical information, including the IP address, MAC address, connection status, and signal strength. To obtain this report without a computer, use the printer's control panel.
Click the button Wireless On the control panel, check to make sure the printer is on. Then, look for the button with a picture of a sheet of paper or the "Report" button. Press it until the letter "b" lights up or the copy light starts blinking. Then, press the Start Copy button. The printer will print a technical data page.
In the report, you should be interested in the section WirelessThe connection status (Connected/Disconnected) and IP address will be displayed. If the status is "Disconnected," the setup was unsuccessful, and you should return to the previous steps. If the status is "Connected," but the computer doesn't see the printer, the problem is most likely with Windows Firewall or antivirus settings on your PC, which are blocking the detection of network devices.
How can I find out the printer's IP address if the report is unreadable?
If the report cannot be printed, the IP address can be found through the command line on the computer if the driver is already installed. Enter the command ping hp_laser_mfp_135w (or your printer's name) in the command line. The response will include the IP address. The address is also often displayed in the device's status in the Devices and Printers window in the Windows Control Panel.
Can I connect a printer to a guest Wi-Fi network?
Technically, this is possible, but not recommended. Guest networks often have client isolation enabled, meaning devices on the network can't "see" each other. Your computer won't be able to print a document because the router will block packets from passing between your laptop and the printer, even if they're both connected to the same guest access point.
What should I do if the printer sees the network but doesn't connect?
Check your network security type. HP Laser MFP 135w Supports WPA2-Personal standards. If you have legacy WEP or a specific corporate WPA-Enterprise with an authentication server, a direct connection may not work without additional configuration using HP utilities. Also, check if there are any time or traffic limits set in your router settings.
