- 🔄 Activate WPS on your router within 2 minutes.
- ✅ Wait until the indicators light up continuously, confirming success.
Setup via USB cable and computer (Software AP Method)
If the automatic network search doesn't work or your router hides the network name (SSID), you'll have to use a wired connection. For this, you'll need a cable. USB Type-B (printer) and the driver package installed on your computer. Download the full software package from the manufacturer's official website, selecting your model and operating system.
Run the installer and follow the on-screen instructions. When prompted to select a connection type, select "Wireless Connection." At a certain point, the installer will prompt you to connect a USB cable. Once the PC is connected to the printer, the program will transfer the network settings directly to the device's memory. This method is especially useful if you need to enter complex passwords or select a specific network from a list.
☑️ USB Connection Checklist
After transferring the settings, the program will prompt you to disconnect the USB cable. The printer will overwrite the configuration and attempt to connect to the router automatically. Make sure it's not disconnected from power at this point. If everything is successful, you'll be able to find the device in the list of available printers in Windows or macOS.
Using the Epson Smart Panel app for mobile devices
For smartphone and tablet owners, the most convenient option is to use the proprietary app. Epson Smart PanelAvailable for iOS and Android, it allows you to not only print documents and photos but also perform initial network setup.

Using the app interface, you can select your home network from the list and enter the password using your smartphone's convenient keyboard.
Once successfully configured, you'll be able to instantly print documents from cloud storage, scan images directly to your phone, and monitor ink levels in your system. CISSMobile connectivity is especially useful for printing photos from social media without a PC.
Indicator table and problem diagnostics
Understanding the status of a device through light signals is a key skill for troubleshooting. Panel Epson L3151 Minimalistic yet informative. Below is a breakdown of the main indicator modes, which will help you understand at what stage the error occurred.
| Wi-Fi indicator status | Network indicator status | Meaning |
|---|---|---|
| It doesn't burn. | It doesn't burn. | Wi-Fi is off or there is no power |
| It's green | It's green | Successful connection to the network |
| Flashing green | Flashing green | Obtaining an IP address or exchanging data |
| Flashing green | It doesn't burn. | Setup mode (waiting for connection) |
| It's glowing orange | It's glowing orange | Connection error or hardware failure |
If the indicators are orange or flashing in emergency mode, this may indicate an incorrect password, a weak signal, or incompatible encryption standards. In this case, we recommend rebooting the router and repeating the setup procedure, after first resetting the network settings on the printer itself.
Resetting network settings and troubleshooting errors
If your printer freezes while connecting or your Wi-Fi password has changed, you should reset the network settings. This will restore the device to its factory connection settings without affecting printhead settings or ink counters. To do this, press and hold the network button (antenna symbol) and the cancel button (cross) for 5-7 seconds.
After the reset, the LEDs should start blinking, indicating readiness for a new configuration. If the problem persists, check whether AP client isolation is enabled on the router, which prevents devices on the same network from seeing each other. Also, make sure the frequency range matches the printer's capabilities (usually 2.4 GHz; 5 GHz support may be limited).
⚠️ Please note: Router firmware interfaces and driver versions are subject to update. If standard methods don't work, check the latest documentation on the manufacturer's official website or in your internet service provider's account, as security settings may vary.
Remember that wireless network stability depends not only on the printer but also on the signal quality. If the device is located far from the router, consider using a Wi-Fi repeater to boost the signal in the area where the MFP is installed.
