Multifunctional device HP LaserJet Pro MFP M428fdn — one of the most popular solutions for offices and home use due to its reliability and wide range of features. However, many users encounter difficulties when first connecting the printer to a wireless network. Without proper Wi-Fi setup, you won't be able to print from a laptop, smartphone, or tablet, or use scan-to-email or cloud features.

In this article we will look at three official connection methods — via the printer control panel, using the WPS button on the router, and via a mobile app HP SmartYou'll also learn how to diagnose common errors (such as when a printer doesn't see the network or constantly loses connection) and which router settings may interfere with stable operation. Important: Models with firmware older than 2023.05.01 may require a prior software update via USB..

If you've never set up network printers before, don't worry—these instructions are tailored for beginners. For experienced users, we've added advanced tips on optimizing your connection (for example, how to assign a static IP address to your printer in your router).

1. Preparing to connect: What to check before setting up Wi-Fi

Before you begin setup, make sure all the conditions for a successful connection are met. Neglecting these steps often results in errors like "Unable to connect to the network" or "No IP address."

• 📡 The router is turned on and distributing Wi-Fi.: Check that the wireless indicator on your router is green or blue. If you're using a dual-band router (2.4 GHz + 5 GHz), the printer M428fdn supports only 2.4 GHz.
• 🔒 The Wi-Fi password is known: The printer will require a security key (if the network is secured). Make sure you enter the password correctly—the device is case-sensitive.
• 🖨️ The printer is turned on and ready for setup.: There should be no warnings on the panel (such as out of paper or toner). If the Wi-Fi indicator is flashing orange, this indicates an error with the previous connection.
• 📱 Control device: Prepare a laptop, smartphone, or PC connected to the same Wi-Fi network to which you will connect the printer.

If your router uses hidden network (SSID), you'll have to temporarily make it visible or enter the name and password manually through the printer control panel. Also, check if the router is enabled. MAC address filter - If yes, add the printer's MAC address (you can find it in the menu) Settings → Network settings → Wireless network).

⚠️ Attention: If your router is in the mode 802.11n/ac/ax with channel width 40 MHz or 80 MHz, try switching it temporarily to 20 MHz - This increases compatibility with older devices, including some HP models.

2. Method 1: Connecting via the printer control panel

This is the most reliable method and does not require any additional devices. The instructions are suitable for printers with touch screen (like M428fdn) and physical buttons.

Steps:

1. Activate Wi-Fi on the printer: On the home screen, tap Settings (gear icon) → Network settings → Wireless network.
2. Select a network: Find your network in the list of available networks (if it is not there, click Refresh the list). If the network is hidden, select Enter the network name manually.
3. Enter your password: Use the on-screen keyboard to enter the security key. Be careful—the printer is case-sensitive!
4. Confirm connection: After a successful connection, a check mark will appear on the screen and the Wi-Fi indicator on the printer panel will light up. blue (does not blink!).

If the printer asks Security type, select the one that is used on your network (usually WPA2-PSK or WPA3-PSK). If you are not sure, check the router settings in the section Wireless Mode → Security.

3. Method 2: Connecting via WPS (without entering a password)

Technology WPS (Wi-Fi Protected Setup) Allows you to connect your printer to the network without manually entering a password. This is convenient if you don't remember the security key or are afraid of entering it incorrectly. However, not all routers support WPS, and some manufacturers (for example, ASUS or MikroTik) disable it by default for security reasons.

Instructions:

1. Make sure that WPS is enabled on the router. Usually it's a button with the inscription WPS or a lock icon. On some models (for example, TP-Link) you need to hold the button for 3 seconds.
2. On the printer, go to Settings → Network Settings → Wireless → WPS.
3. Select Push button (Not PIN code!) and press Start.
4. For 2 minutes Press the WPS button on the router. If the connection is successful, the printer will print out a confirmation message.

If WPS does not work:

• 🔄 Check if your router supports WPS (check the instructions or the sticker on the back panel).
• ⏱️ Make sure the printer and router are close together (no more than 1 meter) - this increases the chances of a successful handshake.
• 🔒 Some routers block WPS after several unsuccessful attempts. Restart the router and repeat the process.

⚠️ Attention: WPS is vulnerable to brute-force attacks. If network security is critical (for example, in an office), after connecting a printer Disable WPS in your router settings..

6. Advanced Settings: Optimize Wi-Fi for the Printer

If your printer connects but is unstable (for example, printing slowly over the network or losing connection), try optimizing your router settings.

1. Assign a static IP address to the printer

This will prevent your IP address from changing when you reboot your router. Instructions for routers TP-Link:

1. Open your router's control panel (usually 192.168.0.1 or 192.168.1.1).
2. Go to DHCP → Address Reservation.
3. Add a new rule by specifying Printer MAC address (you can find it in the printer's network report) and the desired IP (for example, 192.168.0.100).
4. Save the settings and reboot the router.

2. Configure QoS for the printer

If you have a lot of devices on your network (smartphones, smart TVs, cameras), the printer may slow down. Turn it on QoS (Quality of Service) on the router and assign the printer a high priority:

• 📶 Find the section in your router settings QoS or Traffic priority.
• 🖨️ Add a rule for the printer's MAC address with the highest priority.
• 🔄 Save and reboot the router.

3. Update your printer firmware

Outdated firmware may cause Wi-Fi issues. To update:

1. Download the latest firmware from official HP website (support section for LaserJet Pro MFP M428fdn).
2. Unzip the file and copy it to a flash drive (format FAT32).
3. Insert the flash drive into the printer and go to Settings → Software Update → Update from USB.

⚠️ Attention: Router settings (such as the QoS or DHCP menu name) may vary depending on the model and firmware version. If you can't find the section you need, consult your router's manual.

7. Alternative connection options (if Wi-Fi doesn't work)

If you still can't set up a wireless connection, consider alternative methods:

• 🔌 USB connection: A temporary solution for printing from one computer. Use a cable. USB-A → USB-B (usually included in the kit).
• 🌐 Ethernet connectionIf there's a power outlet near the printer, connect it directly to the router. This is the most stable option for an office environment.
• 📶 Using Wi-Fi Direct: The printer creates its own network, which can be connected to from a laptop or smartphone. It turns on in Settings → Wireless → Wi-Fi Direct.
• ☁️ Cloud printing: If the printer is connected to the Internet (even via a cable), you can print via Google Cloud Print or HP ePrint.

To connect via Ethernet:

1. Connect the printer to the router with a cable LAN (RJ-45).
2. On the printer, go to Settings → Network Settings → Wired Network and turn it on DHCP (automatic IP acquisition).
3. Wait for the printer to receive an IP address (check the network report).

If you have chosen Wi-Fi DirectPlease note that in this mode, the printer will not be connected to your main network. To return to regular Wi-Fi, disable Wi-Fi Direct in the settings.
