How to Connect the HP LaserJet Pro MFP M428fdw to Wi-Fi: 3 Proven Methods

Multifunctional device HP LaserJet Pro MFP M428fdw — one of the most popular solutions for office and home use thanks to its print speed, scanning quality, and wireless support. However, many users encounter difficulties when first connecting the printer to a Wi-Fi network. Unlike a wired connection, where simply plugging in a cable is enough, wireless setup requires precise instructions and consideration of your network's specifics.

In this article we will look at three main connection methods: via the printer control panel, using WPS technology and via a mobile application HP SmartEach method has its advantages: for example, WPS is suitable for quick setup if your router supports this function, and the app HP Smart convenient for users who prefer to control devices from a smartphone. We will also cover common errors (for example, Error 79.0000 or absence of a network in the list) and we will give recommendations on how to eliminate them.

Important: If your M428fdw was previously connected to a different network, before setting up, reset the network settings through the menu Settings → Network settings → Network resetThis will avoid conflicts with saved profiles.

1. Preparing for connection: what to check before starting setup

Before you begin connecting, make sure your network meets the printer's requirements. HP LaserJet Pro MFP M428fdw supports Wi-Fi standards 802.11b/g/n at frequencies 2.4 GHz And 5 GHz, but there are important nuances:

  • 📶 Network frequency: The printer works with 2.4 GHz more stable, especially if the router is in another room. 5 GHz may not receive a signal over a long distance.
  • 🔒 Security type: Supported WPA2-PSK (AES) And WPA3-PSKIf your router is using an outdated one WEP or WPA-TKIP, change the settings.
  • 📡 Router signal: Make sure the printer is in a strong reception area. If the signal is weak, temporarily move the device closer to the router.
  • 🔌 Nutrition: Connect the printer to the network to Start setup - Some features (such as network search) are not available in power saving mode.

Also check if it is enabled on the router AP Isolation mode — it blocks communication between devices on the same network. This mode must be disabled for the printer, otherwise printing from a smartphone or PC will be impossible.

⚠️ Attention: If your router uses guest network If your printer has a separate SSID, it may not connect due to restrictions on accessing local resources. Use the main network.
