Modern office and home tasks require maximum mobility, and printing documents from wireless devices is becoming the de facto standard. Model HP LaserJet Pro MFP M28w It's one of the most popular compact solutions supporting Wi-Fi Direct and standard LAN connectivity. However, initial device configuration often presents challenges for users accustomed to wired interfaces or those unfamiliar with the security nuances of modern routers.
Integrating a printer into an existing infrastructure requires careful attention, as success depends on the correct network settings and encryption protocol compatibility. Unlike older models, which required a USB cable for initial setup, modern algorithms allow for completely over-the-air pairing using the MFP's control panel or a mobile app. It's important to understand that the device's future stability directly depends on the quality of the initial setup and the choice of connection method.
In this guide, we will go through all the connection steps in detail. HP M28w to your Wi-Fi network, let's look at how to use the utility HP Smart We'll also cover the WPS method, as well as troubleshooting common errors that occur when interacting with routers from different manufacturers. You'll gain a complete understanding of how to make your printer accessible to all computers and smartphones in your home or office without the hassle of unnecessary cables.
Preparatory stage and network compatibility testing
Before you begin setting up the equipment, you need to make sure your local network is ready to accommodate new devices. This is a critical point for the model. M28w is the frequency range support: this printer operates exclusively in the range 2.4 GHz and does not support 5 GHz networks. If your router broadcasts a single network with combined names (Smart Connect), automatic protocol detection may be difficult, so it is recommended to temporarily separate the networks or ensure the device is connected to the guest 2.4 GHz segment.
You'll also need to know the exact name of your wireless network (SSID) and its password. Pay attention to case sensitivity: the system distinguishes between uppercase and lowercase letters, so any error will result in a connection failure. If the password uses special characters, make sure you enter them correctly, especially if you're using the virtual keyboard on your smartphone or tablet for initial configuration.
⚠️ Important: Make sure that Client Isolation is not enabled on your router, as this feature prevents devices within the same Wi-Fi network from exchanging data, making it impossible to print from your computer if the printer is already connected.
It is recommended to place the printer and the device being configured (laptop or smartphone) no more than 1-2 meters from the router during the pairing process. This will ensure maximum signal strength and minimize the risk of data packet loss when transferring network settings to the device's memory. HP LaserJet Pro.
Resetting the printer's network settings before starting work
If the printer was previously used on a different network or setup was unsuccessful, conflicting settings may have been stored in the device's memory. For the model HP M28w There's a simple way to reset your network settings to factory defaults without a full reset of the entire device. This will clear saved Wi-Fi profiles and allow you to start the configuration from scratch, often solving 90% of printer "invisibility" issues.
To reset the device, press and hold two buttons on the control panel simultaneously: the wireless button (antenna icon) and the cancel button (cross icon). Hold them for 3-5 seconds until the power indicator blinks. The device will then reboot the network module, and the wireless indicator will begin flashing blue, indicating it's ready to search for a network or create an access point.
- 📶 The Wi-Fi indicator is flashing blue - the printer is in setup mode and ready to connect.
- 🔵 The Wi-Fi indicator is blue - the device is successfully connected to the network and ready to use.
- 🟡 The Wi-Fi indicator is yellow - a network error has been detected or the connection has not been established.
- ⚪ The Wi-Fi indicator is off — the wireless module is disabled in the device settings.
After performing the reset, it is recommended to wait about a minute for the printer's operating system to fully load. At this point, the device will automatically create its own access point. HP-Setup-M28w, if it does not find any previously saved networks, which will allow you to continue setting up using standard software tools.
Using WPS technology for quick connection
The easiest and fastest way to connect HP LaserJet Pro M28w the router is using technology WPS (Wi-Fi Protected Setup). This method automatically transmits the network password, eliminating the need to enter it manually, thus eliminating typos. However, for this method to work, your router must support WPS and have it enabled (it's enabled by default on most modern routers).
The connection process is as follows: press and hold the wireless button on the printer's panel until the indicator light starts flashing. Then, within 2 minutes, press the WPS button on your router. This button is usually marked with a corresponding symbol or text. Once pressed, the router and printer will begin exchanging encryption keys.
☑️ Pre-WPS Check
If the process is successful, the wireless indicator on the printer will stop blinking and turn solid blue. This means the device has received an IP address from the router's DHCP server and is ready to use. If the indicator turns yellow or continues blinking, the connection is not established, and you should try manual configuration using the software.
Setup via the HP Smart app (Windows, macOS, Mobile)
If the WPS method is not available or you prefer more detailed control over the process, the best solution is to use a proprietary application. HP SmartThis cross-platform solution automatically finds HP printers on the network and helps you set them up. First, make sure your computer or smartphone is connected to the same Wi-Fi network you plan to connect the printer to.
Download and install the application HP Smart From the Microsoft Store, Mac App Store, or Google Play/App Store. After launching the app, click the "Add Printer" button or the plus sign. The app will begin searching for devices. If the printer is in setup mode (blue indicator flashing), the app will prompt you to set it up.
During setup, the app may request location permission (especially on Android), as this is necessary to scan for available Wi-Fi networks. Follow the on-screen instructions: select your network from the list and enter the password. The app will automatically transfer this data to the printer via a temporary direct connection or via the HP cloud service.
⚠️ Please note: The HP Smart app interface may be updated. If you don't see the obvious "Set up a new device" button, look for the "Printer Setup" or "Add a printer" section in the main menu.
Once the process is complete, the application will confirm a successful connection and prompt you to install the full drivers and additional software. We recommend installing the full package to gain access to all scanning and toner level monitoring features.
Solving common connection problems
Even if all instructions are followed, users may encounter situations where the printer is not visible on the network or does not connect. One common cause is incompatibility with security standards. Printers of the series LaserJet Pro may not work correctly with new encryption standards WPA3If the router is configured exclusively for this mode, you'll need to enter the router settings and switch the security mode to mixed (WPA2/WPA3) or temporarily to WPA2.
Another common issue is the limited number of devices in the router's DHCP pool. If your network is a smart home and has numerous gadgets, the address pool may be exhausted. In this case, the printer simply won't receive an IP address. The solution is to increase the address range in the router settings or reboot the router itself to reset the address lease.
| Symptom | Possible cause | Solution |
|---|---|---|
| The Wi-Fi indicator is blinking blue | Setup mode, no connection | Start a search through HP Smart or press WPS |
| The Wi-Fi indicator is yellow | Weak signal or password error | Go closer to the router and double-check the password. |
| Printer not found in HP Smart | Firewall is blocking search | Allow the application to access the local network |
| Printing is in progress, but the status is "Offline" | IP address conflict | Restart the router and printer |
It's also worth mentioning the impact of antivirus software on Windows computers. Aggressive firewall settings can block the detection of network printers. When installing drivers, the system may request permission to access the network. Select "Private Network" or "Home Network" to open the necessary ports for local data exchange.
Setting up Wi-Fi Direct for printing without a router
In situations where the main Wi-Fi router is unavailable, overloaded, or you are in a location where the use of the corporate network is limited, the model HP M28w offers an excellent alternative - technology Wi-Fi DirectThis mode allows the device to create its own wireless network, which smartphones, tablets, and laptops can connect to directly, without the need for a router.
To activate this mode, press the Wi-Fi Direct button on the printer's control panel (the smartphone icon next to the antenna). If the indicator lights up, the feature is activated. To find the network name and password for connecting, you need to print a configuration report. To do this, press and hold the Resume button (the triangle) until the toner indicator lights up, then release it. The printer will print a page with the information.
What is the difference between Wi-Fi and Wi-Fi Direct?
Wi-Fi mode connects the printer to the router, allowing all devices on the network to print simultaneously. Wi-Fi Direct mode creates a separate access point on the printer itself. When connected to Wi-Fi Direct, your phone may lose internet access if it doesn't support dual Wi-Fi channels.
By connecting to the printer network (for example, Direct-HP-M28w) from your device, you can print documents just as you would over a regular network. However, it's important to remember that in this mode, the printer can typically only serve one connected device at a time, and data transfer speeds may be lower than through a full-fledged router.
Frequently Asked Questions (FAQ)
Can the HP M28w connect to a hidden Wi-Fi network?
Yes, this is possible, but not through automatic discovery. You'll need to manually configure the IP address through the Embedded Web Server (EWS) or the HP utility, where you can manually enter the SSID of a hidden network. However, for stability, it's recommended to make the network visible, hiding its name only from outsiders but leaving broadcasting enabled for IoT devices.
The printer stopped responding to network traffic after changing the router. What should I do?
When you change your router, the gateway IP address and often the address range change. The printer "remembers" the old settings. You need to reset the network settings on the printer itself (as described in the second section) and reconnect to the new network as if it were a new one.
Does the HP M28w work with 5GHz networks?
No, model HP LaserJet Pro MFP M28w The printer is equipped with a module that only operates in the 2.4 GHz band. If your router only broadcasts 5 GHz, the printer won't see the network. You need to enable 2.4 GHz network broadcasting in your router settings.
How to find the IP address of a printer on the network?
The easiest way is to print a network configuration report by pressing and holding the "Continue" button (the triangle) on the printer control panel. The IP address will be listed in the IPv4 section. You can also find the address in the HP Smart app under Printer Information.
Do I need to install drivers if I print from my phone?
Printing from mobile devices (iOS/Android) doesn't require installing drivers on your phone; the HP Smart app or built-in print service (AirPrint/Mopria) is sufficient. Drivers are only required for computers (Windows/macOS) to fully utilize all scanning and management features.
