It is impossible to imagine a modern office without wireless technologies, and HP Laser MFP 135r is an excellent example of a compact device capable of operating in such an environment. Switching to a wireless connection eliminates unnecessary cables, allowing the MFP to be placed anywhere with network coverage. This is especially relevant for small workspaces, where every centimeter of space is at a premium.
Setup process Wi-Fi Installing a wireless module may seem complicated at first glance, but following the steps consistently guarantees a successful result. It's important to understand that reliable operation depends not only on the printer itself but also on the router's signal strength. In this article, we'll cover in detail all available methods for enabling wireless printing, including using a USB cable for initial configuration.
Before you begin tinkering with settings, make sure your network equipment is working properly. Router The device must be turned on and broadcasting a network, and the computer or smartphone used for setup must be connected to the same network. Ignoring this basic rule is the most common cause of failure when attempting to sync devices.
Preparing for wireless connection
The first step is always to check the physical condition of the device and its readiness for operation. Make sure that HP Laser MFP 135r The device is plugged into a power outlet and ready to use, as indicated by the power indicator. Also, check that there is paper in the tray and toner in the cartridge, as some models may block network functions if there are critical media feeding errors.
The second step is to gather the necessary information about your wireless network. You need to know the exact network name (SSID) and a password for access. If the password contains complex characters or is case-sensitive, it's best to write them down or copy them in advance to avoid errors when entering them through the printer control panel. Even a single character error will make connection impossible.
It is also worth noting that most home and office printers, including the model under consideration, only support operation in the range 2.4 GHzIf your router broadcasts two networks (2.4 GHz and 5 GHz) with the same name, conflicts may occur. In this case, it's recommended to temporarily separate the networks or ensure the device is attempting to connect to the correct frequency band.
⚠️ Attention: If your router uses filtering by MAC addressesTo do this, you need to whitelist the printer's address in advance. The address is usually printed on a sticker on the back of the device or can be printed via the configuration report.
Using the WPS button for quick setup
The easiest way to establish a connection between a router and a printer is the technology WPS (Wi-Fi Protected Setup). This method allows you to transfer network settings automatically, eliminating the need to manually enter a long password using the device's cumbersome keyboard. To successfully implement this method, your router must support this feature and have a corresponding physical or software button.
The activation process looks like this: on the control panel HP Laser MFP 135r You need to find and hold the wireless button until the indicator light starts flashing. This usually takes about 3-5 seconds. After that, you need to press the button within two minutes. WPS on your router's body. The devices will find each other and exchange encryption keys.
- 📡 Press and hold the Wi-Fi button on the printer until the indicator light flashes.
- 🔌 Within 2 minutes, press the WPS button on your router.
- ✅ Wait until the Wi-Fi indicator on the MFP stops flashing and lights up steadily.
If the wireless network indicator is constantly lit, this indicates a successful connection. However, if the indicator continues to blink for too long or goes out, the connection attempt was unsuccessful. In this case, check whether the two-minute timeout has expired or try again closer to the router.
☑️ WPS Readiness Check
Setup via USB cable and software
The most reliable method recommended by support specialists is the initial setup through USB interfaceThis method allows the drivers and HP Smart utility (or the full driver package) to automatically transfer Wi-Fi settings from your computer to the printer. You'll need a standard USB Type-B cable, which is often included but may require a separate purchase.
First, download the latest version of the software from the manufacturer's official website. When launching the installer, select the connection type "Wireless" or "Wi-Fi." The program will automatically detect the device connected via USB and prompt you to transfer the settings of the current network to which your computer is connected. This eliminates human error and password errors.
During the installation process, the setup wizard may prompt you to temporarily disconnect the USB cable after the data transfer. This is a normal procedure required to switch the printer's network adapter mode. After this, the computer should find the device over the network, confirming the operation was successful.
| Connection method | Necessary equipment | Complexity | Speed of setup |
|---|---|---|---|
| WPS | A router with WPS support | Low | High |
| USB + software | USB Type-B cable, PC | Average | Average |
| Control Panel | Printer only | High | Low |
Manual configuration via control panel
If you don't have a USB cable at hand, and the WPS function on your router doesn't work or isn't present, you still have the option of manual configuration directly via the buttons on the case. HP Laser MFP 135r. This method requires careful attention, as menu navigation is accomplished using a limited set of buttons and LED indicators.
To enter setup mode, press and hold the wireless button until the indicators begin flashing in a specific pattern, indicating readiness for input. Next, use the confirmation button (usually the "Copy" button or a separate "OK/Start" button, depending on the board revision) to select manual input mode.
Entering characters is accomplished by repeatedly pressing the confirmation button. For example, the first press might select the letter "A," the second "B," the third "C," and so on. After selecting the desired character, press the "Navigate" button (often indicated by an arrow or the # symbol) to move to the next character. This process can take time, especially if the network name is long.
⚠️ Important: When manually entering your password, pay close attention to the capitalization. The control panel doesn't have a full screen, so the only way to correct the error is to restart the password and reset the network settings.
After entering the network name and password, the device will attempt to connect. A successful connection will be confirmed by a change in the LED status. If the connection is unsuccessful, repeat the process, carefully checking each character entered.
What to do if the printer does not have a screen?
On the 135 series models, navigation is performed by blinking indicators. One blinking LED indicates standby mode, two blinking LEDs indicate connection, and a steady light indicates success. The combinations can be found in the table on the inside of the scanner cover.
Installing drivers and printing a test page
Once the printer has received an IP address from the router, you need to install the drivers on the computer or laptop you plan to print from. Even if you used USB for setup, for full Wi-Fi operation, you may need to install a full software package that adds a virtual port to the system.
Go to Devices and Printers (or Printers and Scanners in Windows 10/11) and click Add a printer. The system should find HP Laser MFP 135 Series on the network. If the automatic search does not return any results, select "The printer I want isn't listed" and enter the device's IP address, which can be found by printing a configuration report (usually by holding down the Cancel or Copy button).
After installing the drivers, be sure to perform a test print. This will confirm that data is being transferred wirelessly without any loss. It is also recommended to test the scanner's network operation if your operating system and installed software support this feature. Scan to PC via Wi-Fi.

Troubleshooting and diagnostics
Even with the correct settings, situations may arise where the printer loses connection to the router or becomes unavailable to computers on the network. A common cause is a change in the device's IP address after a router reboot, if a static address hasn't been reserved. In such cases, rebooting both devices helps: first turn off the router, then the printer, and then turn them back on in reverse order.
Another issue could be incompatibility of encryption standards. If the router is configured to use only WPA3If your printer only supports WPA2, the connection will fail. In this case, you'll need to go to your router settings and enable mixed mode or compatibility mode.
If all else fails, reset the printer's network settings to factory defaults. This is usually done by holding the wireless button for more than 10-15 seconds or by using a combination of buttons. After the reset, the device will return to initial setup mode, and you'll have to repeat the process.
⚠️ Note: Router interfaces and printer firmware versions are subject to update. If the steps described don't match yours, please refer to the manufacturer's documentation or the official knowledge base for the latest information.
How to find out the IP address of a printer without printing?
Press and hold the wireless button on the printer for 10 seconds. The device will print a network configuration report, which will show the current IP address, MAC address, and connection status.
Why can't my HP Laser MFP 135r printer see my Wi-Fi network?
The most common cause is frequency band issues. This model only works on a 2.4 GHz network. If your router only broadcasts 5 GHz or hides the network name (SSID), the printer won't be able to detect it. Also, check if MAC address filtering is enabled.
Can I connect this printer to Wi-Fi without a computer?
Yes, this is possible through the control panel (buttons on the router's case) or through the WPS function, if your router has one. However, to initially install the drivers on your computer or phone, you'll still need to run the pairing process at least once.
What to do if the orange Wi-Fi light is on?
A flashing orange light usually means the connection is in progress or there's a connection error. A steady orange light may indicate access point mode (Direct). Try rebooting your device and router.
Does the HP Laser MFP 135r support 5G Wi-Fi?
No, the built-in Wi-Fi module in the 135 series only supports 802.11 b/g/n in the 2.4 GHz band. To work in modern dual-band networks, make sure the 2.4 GHz band is enabled on your router.
