How to Enable Wi-Fi on an Epson L355 Printer: A Complete A-Z Guide

Multifunctional device Epson L355 — is one of the most popular solutions for home and small offices thanks to its continuous ink supply system (CISS) and wireless printing support. However, many users encounter difficulties when first connecting the printer to a Wi-Fi network. Unlike a wired connection, where simply plugging in a cable is enough, setting up wireless mode requires several steps—and the slightest mistake can result in the printer simply not detecting the network or refusing to connect.

In this article we will look at all possible ways to activate Wi-Fi on Epson L355 — from the standard connection via the control panel to alternative methods using a USB cable or mobile phone. We will pay special attention common mistakes (for example, when a printer can't find a 5 GHz network or requires a password despite entering it correctly) and how to troubleshoot them. If you've already tried setting up Wi-Fi without success, you'll find solutions to 90% of common issues here.

Before you begin, make sure your Epson L355 Updated to the latest firmware version. Outdated firmware may block some wireless features. Also, check if your router supports the following standards. 802.11b/g/n - the printer works only with them and is not compatible with new ones 802.11ac/ax (If your router is dual-band, select the 2.4 GHz network).

1. Preparing the printer and network for connection

Before you turn on Wi-Fi on Epson L355, you need to complete several preliminary steps. Missing these is the main reason why PrinterLater can't find or connect to the network.

Network requirements:

• 📶 The router must broadcast the network in the range 2.4 GHz (the printer does not support 5 GHz). If you have a dual-band router, make sure the networks have different names (SSIDs).
• 🔒 The network password must contain only Latin characters and numbers (Cyrillic or special characters may cause an error).
• 📡 Signal strength: the printer should be within 5-7 meters of the router (walls and partitions weaken the signal).
• 🔄 Security mode: supported WPA2-PSK (AES) or WPA-WPA2Avoid outdated ones. WEP or open networks.

Printer requirements:

• ⚡ Make sure the printer is turned on and in standby mode (the power indicator is green).
• 🖨️ There must be paper in the tray (the printer may request to print a test page with network settings).
• 🔄 If the printer was previously connected to a different network, reset the network settings (see below).

⚠️ Attention: If your router uses the function Smart Connect (automatic switching between 2.4 GHz and 5 GHz), disable it in the router settings. Epson L355 will not be able to connect to the network if the router tries to switch it to the incompatible 5 GHz band.

2. Standard method: connecting via the printer control panel

This is the most reliable method, working 95% of the time. These instructions apply to a printer with factory settings (if Wi-Fi hasn't been configured previously).

Step 1. Activate Wi-Fi Setup mode:

1. Click the button Settings (gear) on the printer control panel.
2. Go to the section Wi-Fi Setup (may be called Wireless communication or Wireless LAN Setup).
3. Select Setting up the connection (Setup Connection).

Step 2. Select a network and enter a password:

4. The printer will begin searching for available networks. Wait for the list to appear (this may take up to 30 seconds).
5. Find your network name in the list (SSID) and select it using the navigation buttons.
6. Enter your Wi-Fi password using the on-screen keyboard. Use the [key] to switch between upper and lower case. ABC/abc.
7. Confirm your input and wait for the message Connected (Connected).

If the printer is successfully connected, it will print a network settings page (Network Configuration Page). It will be indicated on it. IP address, MAC address and connection status. Save this page—you'll need it to set up printing from your computer or phone.
