Setting up a wireless connection for office equipment can often be a real challenge, especially when it comes to EcoTank series MFPs. Epson L3150 This popular model lacks a built-in screen, making entering passwords and navigating the menus difficult. However, thanks to a well-designed system of buttons and indicators, this process can be completed quite quickly if you know the correct sequence of actions.
In this article, we'll cover all available connection methods, from automatic pairing to manual network configuration. You'll learn how to avoid common data entry errors and what to do if your device doesn't detect your home network. Wireless interface This model allows you to print from mobile devices and laptops without unnecessary wires, which makes your workspace much tidier.
Before you begin, make sure your router The MFP is turned on and sharing internet, and the printer itself is filled with ink and ready to use. The distance between the MFP and the access point should be sufficient to ensure reliable signal reception, but not too far to avoid connection interruptions during the setup process. You may also need to know the password for your Wi-Fi network if you decide to use the manual entry method.
Equipment preparation and compatibility testing
The first step is to physically prepare all system components. Make sure that Epson L3150 Plugged into a power outlet and within range of your router's signal. If you plan to connect to a 5 GHz network, please note that this model only supports the standard. 2.4 GHz, which has a longer range, but is often overloaded with neighboring networks.
Check if the router is in the enabled mode. WPS (Wi-Fi Protected Setup), as it's the easiest way to automatically transmit a password without manually entering it. If you don't know how to do this, consult your provider's documentation or look at the sticker on the bottom of your router. In some cases, providers block this feature remotely, in which case you'll have to use alternative methods.
⚠️ Note: If you're using a guest network or corporate Wi-Fi with web authentication (captive portal), you won't be able to connect the printer directly. The device must be connected to a standard network with WPA2 or WPA3 password protection.
To set it up, you'll also need a computer or smartphone with the software installed. While basic setup can be done using buttons, full printing and scanning functionality will require installation. drivers and the Epson iPrint or Epson Smart Panel utilities. Download them in advance from the official website to avoid interrupting the installation process.
Connection method via WPS button
The fastest way to establish a connection between a router and printer is using WPS technology. This method is ideal if you don't want to mess with long passwords or if your computer keyboard is unavailable during setup. You'll need physical access to both devices to press the buttons simultaneously.
Press and hold the network button on the printer control panel Epson L3150 Wait for 3 seconds until the Wi-Fi indicator starts blinking. Then, within two minutes, press the WPS button on your router. If the connection is successful, the network and Wi-Fi Direct indicators on the printer will turn green, indicating that an IP address has been acquired.
- 🟢 Press the Wi-Fi button on the printer and hold for 3 seconds.
- 🟢 Press the WPS button on the router within 2 minutes.
- 🟢 Wait until the indicators stop flashing and light up steadily.
If the indicators continue to flash or remain red, the connection has failed. This may be due to a timeout or incorrect security settings on the router. In this case, try repeating the procedure closer to the router or switch to manually entering the settings via a computer.
☑️ Checklist for a successful WPS connection
Setup via USB cable and computer
If wireless methods don't work or seem too complicated, the classic USB cable method remains the most reliable. You'll need a USB Type-B (printer) cable, which is usually included but may require a separate purchase. This method allows your computer to automatically transfer Wi-Fi settings to the printer.
Run the driver installation file downloaded from the official Epson website. During the installation, select "Wireless Connection" and follow the wizard's instructions. When prompted, connect the USB cable between the PC and the MFP. The system will recognize the device and prompt you to select your network from the list of available networks.
| Setup stage | User action | Expected result |
|---|---|---|
| Launching the installer | Select "Wireless Setup" | Opening the network search window |
| Connecting the cable | Connect PC and USB printer | Communication indicators are activated |
| Network selection | Specify the Wi-Fi name and password | Transferring parameters to the device |
| Conclusion | Disconnect the USB cable | The printer works via Wi-Fi |
After successfully transferring the settings, the program will prompt you to disconnect the USB cable. This is a normal step in the process, as further communication will be over the air. Make sure you haven't uninstalled the drivers, even if you're no longer using the cable, as they are necessary for controlling the scanner and monitoring ink levels.
⚠️ Important: Do not connect the USB cable until the installation program prompts you to do so. Doing so early may trigger the standard installation mode, and the Wi-Fi setup feature will not be activated automatically.
Using Wi-Fi Direct
Technology Wi-Fi Direct Allows you to connect a mobile device or laptop directly to the printer without a router. This is especially useful if you're in a location without access to the main network or if the router is temporarily down. In this mode, the MFP itself becomes an access point.
To activate this feature, press the Wi-Fi Direct button on the control panel. The printer will print a network information page, including the network name (SSID) and password for the connection. This information can also be found by printing a network status report using the button combination.
How to print a network status report?
Press the "i" (information) button and the Wi-Fi button simultaneously. The printer will output a sheet with technical data, including the IP address and connection status.
Connect your smartphone or tablet to a network with a name beginning with "DIRECT-..." and enter the password. You can now print documents using the app. Epson iPrintPlease note that in this mode, the device may not have internet access unless your smartphone is configured to use both mobile internet and Wi-Fi simultaneously.
Installing drivers and software
Even if the indicators are green, the computer won't be able to control the printer without the appropriate software.

- 📥 Download the full driver package from the Epson website.
- 🚀 Run the installation and select the "Wi-Fi" connection type.
- 🛡️ Allow access through the firewall when prompted.
- 🔄 Restart your PC after the installation is complete.
Solution and reset network settings
Sometimes a printer stops responding or loses connection to the router after a firmware update or hardware replacement. In such cases, a full network reset can help. To do this, press and hold the network button and the cancel button (the triangle in a circle) simultaneously for 5-10 seconds until the indicators flash.
After the reset, the device will revert to factory network settings, and you'll need to reconnect as described in the previous sections. Check to see if the Wi-Fi password or encryption type has changed (for example, switching from WPA2 to WPA3 may be incompatible with older printer protocols).

Frequently Asked Questions (FAQ)
Can Epson L3150 be connected to a 5GHz network?
No, the L3150 model only supports the 2.4 GHz standard. If your router broadcasts a single network with a common name for both bands, try separating them in the router settings or force the device to use 2.4 GHz mode.
What should I do if my computer can't see my printer on the network?
Make sure both devices are connected to the same network (not a guest network). Check your firewall and antivirus settings, as they may be blocking detection of network devices. Try temporarily disabling them for diagnostic purposes.
How to find out the IP address of a printer?
Press the "i" button and the Wi-Fi button simultaneously to print a network status report. The IP address will be listed in the TCP/IP section. You can also find it in the list of connected clients in your router's interface.
Does the scanner work via Wi-Fi?
Yes, network scanning is fully supported via the Epson Scan 2 software or the Epson Smart Panel mobile app. Make sure you have the full drivers installed, not just the basic printing tools.
