How to connect the HP Laser MFP 135r printer to a computer via Wi-Fi: a complete guide

Connecting a printer HP Laser MFP 135r Connecting to a computer via Wi-Fi frees you from the tangled mess of cables and allows you to print from any device on the network. However, many users encounter difficulties: the printer doesn't find the network, drivers won't install, or the connection keeps dropping. In this article, we'll walk you through the process step by step—from preparing the router to setting up printing on Windows 10/11 And macOS, and we will also look at typical mistakes and their solutions.

Model HP Laser MFP 135r supports wireless connection via Wi-Fi Direct and standard Wi-Fi, but the setup algorithm is different from other HP printers. For example, there is no display for entering a password - instead, it is used WPS Or manual setup via a computer.

1. Preparing for connection: what you will need

Before setting up, make sure you have everything you need. Without these components, the process may take longer or fail.

• 📄 Printer documentation: Find the serial number (needed for drivers) and the default IP address (usually 192.168.x.1).
• 🔌 power unit: the printer must be connected to the network not through an extension cord - power surges can reset the settings.
• 📡 A router with WPS support: If your router is older than 5 years, check if it is turned on. WPS (usually a button on the back panel).

1. Open your browser and enter the router's IP address (usually 192.168.0.1 or 192.168.1.1).
2. Go to the section Wi-Fi → Security Settings (the name may differ).
3. Set the parameters as above and save the changes.
4. Reboot your router (button Reboot or physical power outage for 30 seconds).

⚠️ Attention: If your router issues IP addresses in the range 10.0.x.x or 172.16.x.x, the printer may not connect. Manually set the range 192.168.x.x in DHCP settings.
