Modern office equipment requires mobility, and the models of the series L3150 Epson printers are no exception. Wireless connectivity allows you to print documents and photos directly from your smartphone or laptop without the need for extra cables. However, initial setup can often be challenging for users accustomed to wired interfaces or those who are unfamiliar with the device's menus.
Activating the wireless module in this MFP isn't always intuitive, as the device lacks a full display for password entry. Instead, it uses a combination of buttons on the control panel and LED indicators, which must be interpreted correctly. Understanding the logic behind the indicators Wi-Fi And Wi-Fi Direct is a key point for the successful completion of the procedure.
In this article, we'll cover all available connection methods in detail, including WPS, reset button configuration, and the proprietary app. You'll learn how to avoid common errors when the router doesn't detect the printer and how to ensure a stable connection for printing from mobile devices. Proper network configuration will allow you to utilize the device's full potential. Epson L3150.
Preparing to set up a wireless network
Before tweaking any network settings, ensure the equipment is physically ready for operation. Make sure the MFP is plugged in, cartridges are installed or the CISS is filled with ink, and paper is loaded in the tray. The power indicator should be solid green, indicating the device is ready to receive commands.
The compatibility of frequency ranges is critically important. Model Epson L3150Like many devices in this class, the printer only supports the 2.4 GHz standard. If your router only broadcasts at 5 GHz, the printer simply won't detect the access point. You need to access the router settings and ensure that the 2.4 GHz network is active and has a separate name (SSID) or is merged with the main network.
⚠️ Attention: Corporate networks with web-based authentication (captive portal) or complex enterprise security protocols (802.1x) are not supported. A standard home network with WPA/WPA2 encryption and a password is required.
It's also a good idea to know your Wi-Fi network password in advance. Unlike computers, where the password may be saved automatically, you'll have to enter it manually through a smartphone app. Make sure the device you'll be using for setup (smartphone or tablet) has Bluetooth and location services enabled, as modern operating systems require these permissions to search for peripherals.
Connection method via WPS (Wi-Fi Protected Setup)
The fastest way to connect a printer and router is using WPS technology. This method eliminates the need to manually enter a long password, reducing the risk of error. First, make sure your router supports this feature—most modern models have a corresponding button on the router or an option in the web interface.
Press and hold the button Wi-Fi on the Epson L3150 printer control panel for approximately 3 seconds. Indicators Wi-Fi And Wi-Fi Direct The Wi-Fi indicators should start blinking alternately. Then, within two minutes, press the WPS button on your router. If everything is successful, the Wi-Fi indicator on the printer will turn green and stop blinking.
If automatic connection fails, the indicators may blink differently or turn red. This may indicate that the signal is too weak or that the WPS function on the router has been disabled by the manufacturer for security reasons. In this case, check the distance between the devices or consider an alternative setup method, such as resetting the network settings.
Setting via the reset button and the i button
If the WPS method doesn't work, you can use the built-in network initialization function. This method is often called the "Reset button method," although technically it involves putting the device into network search mode. On the Epson L3150 panel, look for the button with arrows (the information button). i) and the button Wi-Fi.
Click the button Wi-Fi and, while holding it, press the button iHold both buttons for a few seconds until the indicators flash. The printer will enter setup mode and print a test page with network information, if necessary. In this mode, the device creates its own access point or becomes visible to search utilities.
After activating this mode, you need to search for the printer on your computer or smartphone. The system will prompt you to select your home network from the list and enter the password. This method is more reliable in challenging situations where the automatic WPS protocol fails due to specific router firmware.
☑️ Setup Preparation Checklist
Using the Epson Smart Panel app
The most modern and convenient way of configuration is to use a mobile application. Epson Smart PanelIt's available for iOS and Android and features a graphical interface that greatly simplifies the process. Download the app from the official app store (App Store or Google Play) and register or log in to your Epson Connect account.
Launch the app and click the Add New Product button. The app will automatically find the printer if it's in setup mode (the Wi-Fi indicator is blinking). Follow the on-screen instructions: the app will ask you to select your Wi-Fi network and enter the password. All data will be transferred to the printer via Bluetooth or a direct connection.
The advantage of this method is that once configured, the app becomes a universal control panel. It allows you to not only print, but also scan documents, check ink levels, and clean nozzles. This eliminates the need to search for drivers on your computer for each operation.

Wi-Fi Direct connection
Technology Wi-Fi Direct Allows you to connect your smartphone or laptop directly to the printer, bypassing your home router. This is especially useful when visiting someone or at an office where access to the main network is limited. In this case, the printer itself becomes an access point.
To activate this mode, press the button Wi-Fi on the panel and select the Wi-Fi Direct option (usually the indicator will blink green at regular intervals). A name like DIRECT-XX-EPSON L3150 SeriesThe connection password can be found on the printed network configuration page or set through the app.
Please note that when connecting via Wi-Fi Direct, your phone may temporarily lose internet access if it doesn't support dual Wi-Fi channels. This isn't a problem for printing photos, but scanning to the cloud requires an active internet connection.
What should I do if my printer is not visible in the list of networks?
If the device doesn't appear in the list of available networks, try rebooting the router and printer. Also, make sure MAC address filtering isn't enabled on the router. In rare cases, temporarily disabling your computer's antivirus software may help.
Diagnosing and resolving connection problems
Even if you follow all the instructions, problems may still occur. Most often, the problem is that the devices are on different subnets or the router is blocking new connections. If the Wi-Fi indicator is orange, it means the connection is established, but no data is being transmitted. Red indicates a lost connection or a hardware error.
Try resetting the printer's network settings to factory defaults. To do this, turn off the device, then simultaneously hold down the buttons Wi-Fi And Cancel (triangle in a circle) and turn on the printer, holding them for about 5-10 seconds. Then, repeat the setup procedure again, as if the device had just left the store.
⚠️ Attention: Router interfaces and printer firmware are subject to update. If standard methods don't work, check the user manual on the manufacturer's official website for the latest information, as button functionality may change in newer revisions.
Also, check to see if the print buffer on your computer is full. Sometimes a print job gets stuck in the queue, creating the illusion of a connection problem. Clearing the print queue and restarting the Windows print spooler service often resolves the issue when a printer is visible on the network but unresponsive.
Frequently Asked Questions (FAQ)
Can Epson L3150 be connected to a 5GHz network?
No, this model is equipped with a module that operates exclusively in the 2.4 GHz band. If your router broadcasts networks with the same name (SSID) for both frequencies, try separating them in the router settings, giving the 2.4 GHz network a unique name, and connect the printer to that network.
What password do I need for Wi-Fi Direct?
The default password is listed on the page the printer prints when it's first turned on or after a factory reset. You can also change it in the Epson Smart Panel app, under Wi-Fi Direct settings, to a password that's easy to remember.
The printer prints, but the scanner doesn't work over the network. What's wrong?
Most likely, your computer doesn't have the full driver package, including network scanning utilities, installed. Download the full software package for your operating system from the Epson website, rather than relying on the basic print driver.
How to find the IP address of a printer on the network?
Press and hold the info button i on the control panel for 7-10 seconds. The printer will print a network status report, which will show the current IP address, MAC address, and connection status.
