- 🔹 Press and hold the Wi-Fi button on the printer until the indicator light flashes.
- 🔹 Press the WPS button on the router within 2 minutes.
- 🔹 Wait until the indicator on the MFP stops flashing and lights up steadily.
Once the connection is successful, you can proceed to installing the drivers by selecting "Network Connection" in the installation wizard. The computer will automatically find the printer on the local network using its IP address. This method is especially convenient for macOS users, where drivers are often installed through system updates or AirPrint.
Manual setup via the HP Wireless Setup Wizard
On some corporate networks or when using hidden SSIDs, automatic methods may not work. In this case HP Laser MFP 135wr Allows manual setup through the built-in menu using button combinations. To enter setup mode, press and hold the wireless button and the cancel button (cross) simultaneously for 3-5 seconds.
The printer will enter network search mode. The indicator lights will begin flashing in a specific pattern. To select a network and enter a password without the screen, use the blink count method or use special utilities on your smartphone if the model supports the HP Smart App (although the app's functionality may be limited for the 135w series compared to newer models).
| Indicator | State | Meaning |
|---|---|---|
| Wireless communication | It's on constantly | Successful connection to the network |
| Wireless communication | Flashing | Setup mode or network search |
| Wireless communication | Turned off | The Wi-Fi module is turned off or there is an error |
| Attention | Flashing | Connection error or low signal level |
A more advanced method is to use the utility HP Device Setup, which is sometimes included on a disc (although discs may not be included) or available for download separately. It allows you to manually register Network SSID and password if the automatic search yields no results. Enter the information accurately, observing capitalization, as even a single character error will result in connection failure.
Installing drivers and software
Once the printer is connected to Wi-Fi, you need to install drivers on your computer so that the OS can correctly interpret print commands. HP Laser MFP 135wr It is recommended to use the package HP Full Feature Software, which includes not only basic drivers, but also utilities for scanning and monitoring toner levels.
