Select an item Setting up (Setup), then go to the menu Net (Network). Here you need to find the option Wireless Network Wizard (Wireless Setup Wizard). The printer will begin scanning the air and after a few seconds will display a list of detected access points. Find your router's name (SSID) in the list and click on it.
- 📡 If the network is hidden, select the option to enter the name manually and enter the SSID, taking into account the case.
- 🔑 Enter your Wi-Fi password using the keyboard that appears on the screen and confirm the action.
- ✅ Wait for a message about a successful connection; the wireless network indicator should light up blue.
After successfully entering the data, the printer will attempt to obtain an IP address from the router's DHCP server. This process may take up to a minute. If the connection is established, a network report will appear on the screen, showing the assigned address. Write down this information; it may be useful for manual driver installation or accessing the device's web interface for further fine-tuning.
☑️ Connection check
Using WPS technology for fast connection
If your router supports the technology WPS (Wi-Fi Protected Setup) significantly simplifies the connection process by eliminating the need to manually enter a password. This method is ideal for situations where the password is too complex or you don't want to search through your notes. Your router should have a physical WPS button or a corresponding function in the web interface.
On the control panel HP LaserJet Pro 400 MFP M425dw Press the wireless button. From the menu, select Setting up, then Net and find the item Wi-Fi Protected SetupThe system will offer two options: entering a PIN or pressing a button. Select the "Push Button" method.
Within two minutes of selecting the printer mode, press and hold the WPS button on your router (usually 3-5 seconds) until the security indicator starts blinking. The printer and router will automatically exchange encryption keys. This method is especially convenient because it eliminates the need for human error when typing characters.
What to do if WPS doesn't work?
If automatic connection doesn't occur, check whether the timeout period (usually 2 minutes) has expired. Also, make sure the WPS feature isn't disabled in your router's security settings. In rare cases, antivirus software on your computer may block this protocol, in which case it's best to use manual entry via the setup wizard.
Installing drivers and software
Once the device is connected to the network, you need to install the software on the computers that will be printing. Don't use the disc that came with the box, as the driver versions are often outdated. Go to the official HP support website and enter your model number. M425dw and download the full driver package for your operating system version.
Run the setup file and select the connection type WirelessThe installer will begin searching for the device on the network. If the printer was configured correctly in the previous steps, it will appear in the list of available devices. Select it and follow the instructions of the installation wizard, which will download the necessary components and monitoring utilities.
| Software component | Purpose | Necessity |
|---|---|---|
| HP PCL 6 Driver | Basic Print Driver | Necessarily |
| HP Scan | Scanner control | Recommended |
| HP Utility | Toner level monitoring | As desired |
| HP ePrint | Cloud printing | Optional |
During the installation process, you may be asked to confirm your use of the device on the network. Accept any firmware update requests that may arise. This will ensure stable operation. network protocols and will close potential security vulnerabilities, which is especially important for office equipment that stores document history.
Setting up printing from mobile devices
Modern users often need to print documents directly from their smartphone or tablet. HP LaserJet Pro 400 MFP M425dw the technology is perfect Apple AirPrint for iOS devices and Mopier or HP Smart for Android. The main requirement is that the mobile device and printer must be on the same Wi-Fi subnet.
iPhone or iPad users don't need to install any additional apps. Simply open a document or photo, tap the "Share" button, and select "Print." Your MFP should appear in the printer list. If the device isn't found, check to see if Client Isolation is enabled on your router, which prevents data exchange between devices within the network.
- 📱 For Android, download the HP Smart app from Google Play for advanced functionality.
- 📄 To print photos, use standard galleries with support for system printing services.
- ☁️ To print remotely, set up HP ePrint through the printer's web interface.
⚠️ Attention: Connecting a large number of mobile devices may increase the load on the wireless channel. If printing is slow, try switching your router to a less congested channel or using the 5 GHz band if the printer and router support dual-band mode (although this model operates primarily on the 2.4 GHz band, the router should be able to transmit signals correctly).
Diagnostics and solution
Even with proper configuration, situations may arise where the printer becomes unavailable. This is often caused by a device changing its IP address, unless a static address is reserved for the printer in the router. Rebooting the router can cause the address to change, causing computers to lose connection to the printer, as they will search for it using the old path.
Print a network configuration report by clicking the corresponding button in the reports menu on the printer control panel. Compare the IP address in the report with the address listed in the printer properties on your computer (Start -> Devices and Printers -> Printer Properties -> Ports tab). If the addresses don't match, remove the old printer and add a new one with the current IP address.
Another common cause of failures is power-saving modes. The printer may go into deep sleep and take a long time to wake up, causing the computer to consider it offline. Access the device settings via a browser (by entering the IP address in the address bar) and find the "Power" section. Settings -> Energy and increase the sleep time or disable it for testing.
Why can't my printer see my Wi-Fi network?
