Modern office tasks require mobility, and a wired connection to a printer often becomes a serious limitation. Model HP LaserJet Pro MFP M125rnw It is equipped with a built-in wireless module, which allows you to place the device in any convenient place where there is network coverage, and not just next to the computer.
However, the initial setup wireless connection This can be challenging for users accustomed to simple USB cables. The process requires strict adherence to the correct sequence of steps, as the drivers must be installed at the correct time.
In this guide, we'll cover all available Wi-Fi activation methods, including WPS, standard installation from a disk, and configuration via mobile devices. You'll learn how to properly prepare MFP to work on a local network and avoid typical errors that block printing.
Preparing equipment and checking network parameters
Before installing the software, make sure your wireless router is working properly. The computer or laptop on which you plan to install the drivers must be connected to the same Wi-Fi network to which you want to connect the printer.
It's important to know your network name (SSID) and password in advance. If your router has filtering enabled, MAC addresses, you will need to find the printer's unique identifier, which is usually located on a sticker on the back of the device or printed on the information page.
Make sure the MFP is unpacked, all shipping tapes are removed, and the toner cartridge is installed. Without toner installed, the device may not enter Ready mode, making it undetectable on the network.
- 📶 Make sure your router is broadcasting a signal in the 2.4 GHz range, as older printer models may not support 5 GHz.
- 🔌 Connect the device to the power supply and wait until the warm-up cycle is complete.
- 📄 Check that there is paper in the tray and that the rear cover is tightly closed.
- 💻 Prepare a computer with internet access to download the latest drivers.
⚠️ Important: If your router broadcasts networks with the same name (SSID) for both 2.4 GHz and 5 GHz frequencies, the printer may attempt to connect to an unsupported frequency. In this case, we recommend temporarily separating the networks in your router settings or using WPS.
Resetting the printer's network settings
If the device was previously used on a different network or the router settings were changed, the old configuration may conflict with the new one. For HP LaserJet Pro M125rnw There is a simple procedure to reset network settings to factory defaults.
On the control panel, locate the button with the wireless antenna icon. Press and hold this button along with the Cancel button (the cross) for 3-5 seconds until the lights start flashing simultaneously. This will clear all saved Wi-Fi profiles.
After the reset, the wireless indicator should start blinking blue, indicating that the printer is searching for a network and is ready to pair. If the indicator remains solid blue, the device is already connected to a network.
☑️ Pre-reset check
WPS method: quick connection without entering a password
The easiest way to connect HP LaserJet to Wi-Fi – use WPS (Wi-Fi Protected Setup). This method allows you to transfer network settings automatically, without having to manually enter a complex password on your computer.
Press and hold the wireless button on the printer's control panel until the light starts blinking. Within two minutes, go to your router and press the WPS button on it. It's usually marked with a corresponding icon.
The device will automatically exchange encryption keys. The process is complete when the Wi-Fi indicator on the printer stops flashing and turns solid blue. This means MFP Successfully received an IP address from the router.
What to do if there is no WPS button on the router?
If there's no physical button, log into your router's web interface (usually at 192.168.0.1 or 192.168.1.1) and find the Wireless or Wi-Fi section. There should be a software button for activating WPS. Press it and immediately start searching for the printer.
Installing drivers and software
After successfully connecting the device to the router, you need to install the drivers on your computer. For the model M125rnw It's critical to select the correct connection type in the installer. Do not connect a USB cable if you plan to use Wi-Fi.
Download the full driver package from the official HP support website. When launching the installer, select the "Wireless Network Connection" option. The program will begin searching for the device on the network.
If the installer doesn't find the printer, make sure your computer and MFP are on the same subnet. Sometimes you may need to temporarily connect the device via USB cable only during the network setup phase, after which the cable can be removed. M125rnw Direct setup via panel or WPS is preferred.
| Installation stage | User action | Indication on the printer |
|---|---|---|
| Search for a device | Selecting the connection type in the driver menu | The Wi-Fi indicator is blinking |
| Detection | Confirming the selection of the found printer | The Wi-Fi indicator is constantly on |
| Installing software | Waiting for file copying to complete | Toner and Ready indicators are active |
| Test print | Print a test page | Short-term activity of all indicators |
Setting up printing from a smartphone (Android and iOS)
Mobile printing is a standard feature, and HP LaserJet Pro MFP M125rnw fully supports the technology AirPrint for Apple devices and Mopria For Android. You don't need to install any additional apps to use it, as long as your OS is up-to-date.
Make sure your smartphone is connected to the same Wi-Fi network as the printer. Open a document or photo, tap "Share" or the menu icon, then select "Print." The name of your MFP should appear in the list of available devices.
For advanced features such as scanning to your phone or monitoring toner levels, it is recommended to install the app. HP SmartIt will automatically detect the device on the local network and allow you to manage the print queue.
- 📱 For iOS: Use the built-in AirPrint feature without installing drivers.
- 🤖 For Android: Check for the Mopria print service in your system settings.
- 📲 The HP Smart app is available on the App Store and Google Play for advanced management.
⚠️ Note: Wi-Fi Direct allows you to print without a router by creating a direct connection between your phone and printer. However, in this mode, the printer will not have internet access, which may block some cloud-based features.
Diagnosing and resolving connection problems
During operation, situations may arise where the connection to the device is lost. This is often caused by a change in the printer's IP address by the router or by power saving settings. If the Wi-Fi indicator is blinking, the connection has been lost.
Try rebooting your router and printer in the following order: first, turn on the router and wait until it fully boots up, then turn on the MFP. This will allow the device to correctly obtain a network address.
If the issue persists, print a network configuration report. To do this, press and hold the Cancel button (the cross) until printing begins. In the report, check the wireless connection status and current IP address.
Why is the printer not visible on the network?
Antivirus programs often flag the printer's network port as potentially dangerous. Add the device to the exceptions list or temporarily disable the firewall to check.
What should I do if the computer doesn't see the printer after installing the drivers?
Check if the printing service is enabled in Windows. Press Win+R, enter services.msc, find "Print Spooler" and ensure the service is running. You can also try adding the printer manually via "Devices and Printers" → "Add a Printer" → "The printer I want isn't listed," selecting the TCP/IP address, which can be found in the configuration report.
Can this printer be connected to 5GHz Wi-Fi?
Model HP LaserJet Pro MFP M125rnw The printer is equipped with a module that only operates in the 2.4 GHz band. If your router broadcasts a 5 GHz network with the same name, the printer may not connect. It is recommended to separate the network names (SSIDs) for different frequencies in the router settings, for example, by adding "_5G" to the high-speed network name.
How to find out the IP address of a printer without printing a report?
If you already have the drivers installed on your computer, open Devices and Printers in the Windows Control Panel. Right-click the icon HP LaserJet Pro MFP M125rnw, select "Properties," and then go to the "Web Access" or "Ports" tab. The device's current IP address will be listed there.
