Step 1: Check the Basics

Before diving into more advanced fixes, make sure of the following:

The printer is powered on and not showing any error lights.
Your Wi-Fi router is working properly and connected to the internet.
Your computer or mobile device is connected to the same Wi-Fi network you want to connect the printer to.
The router is not using MAC address filtering, which can block new devices.

Step 2: Restart All Devices

Simple restarts can often fix temporary connectivity glitches:

Turn off your printer, router, and computer.
Wait for about 30 seconds.
Turn on the router first, then the printer, and finally the computer or mobile device.
Try reconnecting the printer to the Wi-Fi.

Step 3: Reset Network Settings on the Printer

If the printer was previously connected to another network or is not responding to setup, resetting the network settings may help:

Press and hold the Wi-Fi button on the printer until the Wi-Fi and power lights start flashing.
This will reset the printer’s wireless settings to default.
Now, you’re ready to set up the Wi-Fi connection from scratch.

Step 4: Reconnect the Printer Using Wi-Fi Setup Mode

To reconnect the Epson L3150 to Wi-Fi:

Press and hold the WPS or Wi-Fi button on the printer for about 5 seconds until the Wi-Fi light begins to flash.
Within 2 minutes, press the WPS button on your router.
Wait for the Wi-Fi light on the printer to stop blinking and remain steady—this confirms a successful connection.

If your router does not support WPS, follow the software setup method below.

Step 5: Use Epson Software for Manual Wi-Fi Setup

If WPS fails or is not supported:

Download the Epson Printer Setup Utility from the Epson support website.
Install and run the utility on your Windows or macOS device.
Select “Wireless Setup” and follow the on-screen instructions.
When prompted, connect the printer temporarily to your computer via USB.
Enter your Wi-Fi network name (SSID) and password.
The printer will save the settings and connect to the network. You can then remove the USB cable.

Step 6: Confirm the Printer Is Online

After setup, check that:

The Wi-Fi light on the printer is solid, not blinking.
Your printer appears in your computer’s Printers & Scanners list (on Mac or Windows).
You can print a test page or scan over the wireless network.

Step 7: Install the Latest Drivers

Outdated drivers can interfere with wireless communication.
