It is impossible to imagine a modern office or home workplace without a multifunctional device that combines a printer, scanner and copier. Model HP LaserJet Pro MFP M125rnw It deservedly enjoys popularity due to its reliability, print speed, and, most importantly, built-in wireless connectivity. However, initial Wi-Fi setup often raises questions for users accustomed to wired connections or new to network printers.
The main difficulty is that wireless interface Requires accurate network settings and proper interaction with the router. Unlike a USB cable, which works simply by plugging it in and using it, a wireless connection requires a stable signal and proper security settings. In this article, we'll cover all connection steps in detail, from choosing a location to setting up printing from a smartphone.
Before you start any active actions, you need to make sure that your router It's turned on and broadcasting internet, and the printer itself is within a strong signal range. It's important to understand that frequency 2.4 GHzThe network used by most budget printers can be susceptible to interference from microwave ovens and neighboring networks. Therefore, properly preparing the space and equipment is half the battle.
Preparing equipment and checking network compatibility
The first step is to physically prepare the device for wireless operation. The device HP M125rnw The printer is equipped with a basic monochrome screen and a limited set of navigation buttons, requiring careful data entry. Ensure paper is loaded in the tray, the toner cartridge is installed correctly, and the protective tape is removed.
Compatibility with your wireless network's security standards is critical. The printer supports encryption protocols. WPA2 And WPA3, but difficulties may arise with mixed modes or corporate networks with Radius authentication. For home use, ensure your router doesn't use MAC address filtering without first registering the new device.
⚠️ Caution: If your router broadcasts both 2.4 GHz and 5 GHz networks under the same name (SSID), the printer may become lost or not see the network. We recommend temporarily separating the network names in your router settings or ensuring that the device is connected to the 2.4 GHz band.
It's also worth checking whether the AP (Client Isolation) feature is enabled on your router, which prevents devices on the local network from communicating with each other. When this feature is enabled, the computer simply won't see the printer, even if both devices are connected to the same Wi-Fi network.
☑️ Check before setup
Reset network settings and enter the wireless menu
If the printer was previously used on a different network or was purchased used, it is strongly recommended to reset the network settings to factory defaults. This will avoid conflicts with IP addresses and saved profiles. To do this, click the Settings button (gear icon) on the control panel and find the item Network or Net.
In the network menu, select the option Restore Network Defaults (Restore network settings) and confirm the action. After the communication module reboots, the wireless indicator should start blinking, indicating it's ready to search for a network. If the indicator remains solid, the device is attempting to connect to a previously saved access point.
To start setting up a new connection, go to the menu Wireless (Wireless) and select Wireless Setup Wizard (Wireless Setup Wizard). The printer will begin scanning the surrounding area and after a few seconds will display a list of available networks (SSIDs). Find the name of your home network in the list.
When you select a network, a password entry window will open. Use the navigation buttons (up/down arrows) to select characters and the button OK to confirm each character. Be careful: letter case is important, and symbols like periods and underscores may be found in additional character menus.
WPS method: quick connection without entering a password
There is an easier way to connect HP M125rnw to the network if your router supports the technology WPS (Wi-Fi Protected Setup). This method allows you to automatically transmit the password by pressing a button on the router. This is ideal for those who are worried about entering a long security key incorrectly.
On the printer's control panel, press the wireless button until the light starts blinking. Then, within 2 minutes, press the WPS on your router. It's usually marked with a corresponding icon or two arrows forming a circle. Hold it down for a few seconds until the router's indicator light starts flashing.
The printer and router will automatically exchange authorization data. This process takes between 30 seconds and 2 minutes. If the connection is successful, the wireless indicator on the MFP will turn blue (or green, depending on the model) and stop blinking.
- 📶 Make sure the WPS indicator on your router is lit before pressing the button.
- ⏱️ The interval between pressing the button on the printer and the router should not exceed 2 minutes.
- 🔒 The WPS method does not work if this feature is disabled in the router's security settings.
It's worth noting that some providers or router models may have a WPS button combined with a reset function. In this case, a short press activates WPS, while a long press (more than 5-10 seconds) resets the router. Be careful when using the buttons on the back of the router.
What to do if WPS doesn't work?
If the printer's indicator light stops blinking and turns red or orange, the connection is not established. Try repeating the process closer to the router, or switch to manual password entry via the Wireless Setup Wizard menu.
Installing drivers and software from a disk or website
Once the printer is successfully connected to Wi-Fi, you need to install the drivers on your computer. While operating systems like Windows 10 and 11 often automatically detect the device on the network, full functionality (scanning, toner level monitoring) requires the full software package. HP Smart or classic drivers.
It is recommended to download the latest driver version from the manufacturer's official website, as the versions on the disk may be outdated. During the installation process, select the connection type. Wireless (Wireless) The installer will automatically scan the network and find your HP M125rnw by IP address.
If the automatic search does not yield results, select the "Printer not found" option and enter the IP address manually. You can find the IP address by printing a network configuration report: click the setup button, go to Reports (Reports) -> Network Config (Network configuration).
| Software component | Function | Necessity |
|---|---|---|
| HP Smart / HP Solution Center | Manage scanning, toner levels, settings | High |
| Print Driver (PCL6) | Provides printing of documents from Word, Excel, PDF | Necessarily |
| TWAIN Driver | Scanner driver for working with graphic editors | Average |
| HP Web Jetadmin | Managing a group of printers (for offices) | Low |
During the installation process, you may be asked to confirm that you want to add the device to your Windows security system. Allow network access so your computer can send print jobs.
Setting up printing and scanning from a smartphone (Android and iOS)
One of the main advantages of the model M125rnw is mobile printing support. For iOS devices (iPhone, iPad), the technology is used AirPrint, which doesn't require installing any additional apps. Simply make sure your smartphone and printer are on the same Wi-Fi network, open a document or photo, tap "Share," and select "Print."
For Android and iOS users with advanced functionality, it is recommended to install the app. HP SmartIt allows you to not only print but also scan documents directly to PDF or JPEG format, save them to the cloud, or send them via email. The app automatically detects the MFP on the local network.
If the app doesn't see the printer, check your local network access settings. On iOS, go to Settings -> Privacy -> Local area network and make sure the switch next to HP Smart is enabled. Without this permission, the app won't be able to communicate with the printer.
⚠️ Please note: Mobile printing only works if your smartphone is connected to the same Wi-Fi network as the printer. Printing via mobile internet (4G/5G) without HP ePrint cloud services may not be available on this model or may require complex setup.
To scan in the app, select the printer image on the main screen and tap "Scan." You can choose color or black-and-white scanning, as well as the saving format. Once the scan is complete, you can immediately send the document to a messenger or save it to your gallery.
Diagnosing problems and printing a configuration report
If you're having connection issues, the first step should be troubleshooting. Print a network configuration report to see the current Wi-Fi module status, IP address, and signal strength. To do this, press the setup button, select Reports (Reports) and then Network Config (Network configuration).
In the report, pay attention to the line Link Status (Connection Status). If it says "Connected," then there is a physical connection to the router. If it says "Disconnected," check that the password you entered is correct. The following parameter is also important: Signal Strength (Signal level): If it is below 50%, the printer may be too far from the router or there are obstacles.
A common problem is when a printer's IP address changes due to a router (DHCP). If a computer "loses" the printer, its address may have changed. In this case, setting a static IP address through the printer's web interface (accessible at http://printer-ip-address in a browser) or reconnecting via the setup wizard can help.
- 🔍 Check if your antivirus or firewall is blocking access to the network printer.
- 📡 Make sure that the printer and PC are on the same subnet (the first three numbers of the IP address must match).
- 🔄 Restarting the router often solves problems with the DHCP server freezing.
If nothing helps, perform a full reset of the printer settings via the service menu (usually a combination of buttons when turning on, but for the M125rnw the network recovery menu is sufficient) and repeat the setup procedure again.
Why doesn't the computer see the printer on the network, even though the Wi-Fi is on?
The most common cause is that the computer and printer are connected to different parts of the network (for example, a Guest network and a primary network) or that one device is using the 5 GHz band and the other is using 2.4 GHz, but the network is strictly isolated. Also, check if the "Network Printing" service is enabled in Windows.
Is it possible to connect HP M125rnw directly to a laptop without a router?
Yes, this feature is called Wi-Fi Direct. To activate it, select Wireless -> Wi-Fi Direct -> On in the printer menu. Your computer or phone will see a network with a name like "DIRECT-xx-HP M125." The connection password is usually listed on the printer screen or in the configuration report.
How can I find out the IP address of my printer if I can't print a report?
You can find the IP address in your installed HP drivers: go to Devices and Printers (Windows), right-click the HP M125, and select Properties -> Web Services or Ports tab. The device's current IP address will be listed there.
Does this model support HP ePrint cloud printing?
The M125rnw model is a basic model and may not support the full HP ePrint service, which assigns an email address to the printer, unlike the higher-end M225/M425 series models. However, printing via the HP Smart app and AirPrint is fully supported and is the preferred method for mobile devices.
