Switching to wireless printing opens up new possibilities for working with documents and photos, eliminating the need to run cables across the room. Model Epson L3151 Wireless is a popular solution in the inkjet MFP segment, but initial network setup can be challenging for inexperienced users. In this guide, we'll cover all the available methods for activating the wireless module so you can start printing from any device in your home.
The configuration process depends on which method you choose: automatic via WPS, manual entry of parameters via the Reset button, or using a mobile app. Epson Smart PanelIt is important to understand that wireless network The router itself should be stable and functioning properly. If you just purchased the device, make sure the ink reservoirs are filled and the initial system priming has been completed.
Before moving on to the technical steps, it's worth noting that the menu interface may differ slightly depending on the firmware version. However, the basic operating principles of the indicators and buttons remain the same for the entire L31xx series. A key condition for successful pairing is that the router operates in the 2.4 GHz range, as this model does not support modern 5 GHz networks.
Equipment preparation and compatibility testing
The first step before setting up the network is to physically check the device's readiness. Make sure the printer is plugged in and the power light is solid green. If the ink or paper lights are flashing, troubleshoot these errors first, as the Wi-Fi module may not activate in an alarm state to conserve power.
You'll also need to know your network name and password. For Windows or macOS users, this can be found in the wireless connection properties on your computer. Smartphone users can simply look at the Wi-Fi settings under the current network. Write this information down or keep it handy so you don't have to worry about getting distracted during the setup process.
Pay attention to the device's placement. For reliable signal reception, the router and printer should be in a direct line of sight or located behind the same wall. Metal objects, microwaves, and aquariums can significantly weaken the signal, resulting in intermittent printing.
⚠️ Important: Make sure MAC address filtering is not enabled on your router. If this protection is enabled, you must whitelist the printer's address in the router settings; otherwise, the connection will be blocked.
Check to see if the 2.4 GHz band in your home is overcrowded. If you have multiple neighboring networks, the channel may be clogged, making it difficult for devices to establish an initial handshake. In this case, it might be a good idea to temporarily move the router closer to the printer to perform the configuration.
Quick setup method via WPS button
The easiest way to connect the Epson L3151 to Wi-Fi is using WPS (Wi-Fi Protected Setup). This method transfers security settings automatically, eliminating the need to manually enter a complex password on a computer or phone keyboard.
First, locate the WPS button on your router. It may be a physical button on the back panel or a virtual button in the device's web interface. Press and hold it for a few seconds until the WPS indicator on the router starts blinking.
Immediately after this, approach the printer. On the control panel, locate the button with the antenna icon (Wi-Fi). Press and hold it for about 3 seconds until the Wi-Fi and Wi-Fi Direct lights begin flashing alternately. This means the device has entered WPS network search mode.
☑️ Pre-WPS Check
The device will automatically exchange encryption keys. This process may take up to 2 minutes. If the connection is successful, the Wi-Fi indicator on the printer will turn solid green and the Wi-Fi Direct indicator will turn off. This indicates that security protocol accepted and communication established.
If the Wi-Fi indicator continues to flash or turns orange, the connection has failed. This may happen if you missed the router's button or if WPS is disabled in your provider's settings. In this case, you'll need to use an alternative setup method.
Setting up via the Reset button and the EpsonNet utility
If automatic setup fails, you can reset the network settings and then reconfigure the printer from your computer. This method is more reliable in complex network environments. First, reset the printer's network settings to factory defaults.
Turn off the device. Press and hold both buttons simultaneously: the wireless network button (antenna) and the cancel button (triangle in a circle). Without releasing them, turn on the printer. Hold the buttons for about 5 seconds, until all the control panel lights flash. Then release the buttons.
Now run the program on your computer. EpsonNet Setup Or use the installation disc included with the device. Select "Connect to a wireless network" and follow the wizard's instructions. The program will find the printer in setup mode and prompt you to select your network from the list.
| Wi-Fi indicator | Wi-Fi Direct indicator | Device status |
|---|---|---|
| Turned off | Turned off | Wi-Fi is disabled |
| Flashing (green) | Turned off | Network Search / Setup |
| On (green) | Turned off | Connected to the router |
| Turned off | On (green) | Wi-Fi Direct mode |
| Flashing (orange) | Flashing (green) | Connection error |
After selecting the network, enter the password. The program will transfer the configuration to the printer via a temporary direct connection. After the process is complete, the computer may lose connection with the printer for a short time while it reboots the network module.
What to do if the computer does not see the printer?
If the EpsonNet utility doesn't find the device, check if your computer is connected to the same network you plan to connect the printer to. Also, temporarily disable your firewall or antivirus software, as they may be blocking search packets on your local network. Make sure the printer's Ready light is on and it's not in deep sleep.
Using the Epson Smart Panel mobile app
Modern users often prefer to configure their equipment via smartphone. Epson has developed an app for this purpose. Epson Smart Panel, available for Android and iOS. This convenient tool not only allows you to set up your network but also manage printing and scanning.
Download and install the app from the official store (Google Play or App Store). Launch the app and click the "Add a new printer" button. The app will request location permission—this is necessary to search for Wi-Fi devices within range.
Follow the on-screen instructions. The app will offer to connect your phone to the printer's temporary network or use Bluetooth to transfer settings. During the process, you'll be asked to select your home router from a list and enter the password. Your smartphone will transfer this data directly to the MFP.
The advantage of this method is that once set up, you don't need a computer to print. You can send documents and photos directly from your phone. The app also allows you to check ink level and the state of the nozzles in real time.
It's important to note that the app requires authorization with an Epson Connect account. This is a cloud service that allows remote printing. If you only need local printing, you can skip this step or register later.
Wi-Fi Direct mode for printing without a router
Sometimes you need to print a document in a location where there's no access to the main router, or you don't want to overload the main network. In this case, the "Print" mode is ideal. Wi-Fi DirectIt creates a direct wireless connection between your device and the printer, bypassing the router.
To activate this mode, press and hold the Wi-Fi Direct button on the printer panel (usually the button with a smartphone icon) for 3 seconds. The Wi-Fi Direct indicator will turn green, and the Wi-Fi (antenna) indicator will either blink or turn off, depending on the firmware version.
Press the information button (the letter i) next to the Wi-Fi Direct button to print a page with your current settings. This page will list the network name (SSID) and password for connecting. The network name typically includes the word "DIRECT" and the device model.
On your smartphone or laptop, find the new network in the list of available Wi-Fi connections. Enter the password found on the printed sheet. Once connected, you can print files just like over a regular network, but the transfer speed may be slower.
It's worth remembering that in Wi-Fi Direct mode, the printer may not have internet access if your mobile device doesn't support simultaneous data transfer via cellular and Wi-Fi. This is important if you plan to scan documents directly from your device to the cloud.
Diagnostics and problem solving
Even if you follow all the instructions, problems may still occur. A common issue is that the printer sees the network but won't connect. This may be due to the wrong encryption type. Make sure your router is set to WPA2-PSK (AES), as older WEP protocols or mixed modes may not be supported.
Another common error is an incorrect date and time on the router or printer, which affects security certificates when printing to the cloud. Check the time settings in the router's web interface. Also, try rebooting the router by unplugging it from the power outlet for 10 seconds.
If the Wi-Fi light is green but the computer can't see the printer, check your firewall settings. Sometimes the operating system marks the network as "Public" and blocks device discovery. Change the network profile to "Private" or "Home."
⚠️ Note: Router interfaces and app versions are updated regularly. Button locations and menu item names may differ from those described. Always consult your router manufacturer's official documentation if standard steps don't work.
If problems persist, perform a full network reset on the printer (as described in the section on the Reset button) and try setting it up again while moving closer to the router. Sometimes, assigning a static IP address to the printer in the router settings helps, so that the address doesn't change after a reboot.
Frequently Asked Questions (FAQ)
