Connecting the Epson L3151 Printer to Wi-Fi: A Complete Guide with the Nuances

Multifunctional device Epson EcoTank L3151 — a popular model among home and office users thanks to its economical continuous ink supply system. However, many people encounter difficulties when first connecting the printer to a wireless network. Unlike wired models, where simply plugging in a cable is enough, setting up Wi-Fi requires precise instructions and taking into account the specifics of your router.

This article will help you figure out how to connect Epson L3151 to Wi-Fi from a computer, smartphone, or directly through the printer's control panel. We'll cover all current methods (including WPS), common errors (for example, the code 0x97 (or a blinking Wi-Fi indicator), and we'll also provide recommendations for optimizing your connection for stable printing. If your router uses dual-band mode (2.4 GHz and 5 GHz), you'll learn which channel to select for maximum compatibility.

Important: the instructions are valid for printer firmware versions 1.05 and newer. Devices with earlier software may require a prior update via Epson Software Updater.

1. Preparing for connection: what to check before starting

Before you begin setting up, make sure the following basic requirements are met:

• 📶 The router is turned on and distributes Wi-Fi (the network indicator lights up green/blue).
• 🖨️ Epson L3151 connected to the power grid and within the network's range (no further than 5–7 meters from the router).
• 📱 On your smartphone or computer, the VPN is disabled and Wi-Fi is enabled (the connection must be to the same network as the printer).
• 🔒 You have your Wi-Fi password (if the network is secured). For guest networks with portal authentication (such as in hotels), an alternative method will be required.

Pay special attention Wi-Fi frequency: Epson L3151 only supports range 2.4 GHzIf your router is in the mode 5 GHz or 2.4+5 GHz (Auto), temporarily switch it to 2.4 GHz via the web interface (usually at 192.168.0.1 or 192.168.1.1).

⚠️ Attention: Some providers (eg Rostelecom or Beeline) hide the network SSID by default 2.4 GHz in the router settings. If the list of available networks shows only one (with the suffix _5G), go to the router control panel and enable visibility 2.4 GHz.

Also check if it is enabled on the router client isolation mode (Client Isolation) - This blocks communication between devices on the local network, which will prevent printing from the computer. Disable this option in the Wireless Mode → Advanced Settings.

• 🛡️ Set up Quality of Service (QoS): In your router, prioritize printer traffic by adding its MAC address to the QoS rules.
• 📡 Use a Wi-Fi repeater, if the printer is located far from the router (for example, at the other end of the office).

For office networks with a large number of devices, it is recommended:

• Create guest network specifically for the printer (with a separate SSID and password).
• Limit channel width 2.4 GHz to 20 MHz (instead of 40 MHz) to improve stability.
• Disable the feature 802.11r (Fast Roaming), if it is enabled, it may cause conflicts with Epson L3151.
