Modern printing devices, such as the popular model Epson L355While wireless devices offer a wide range of features, their initial setup often presents difficulties for users. The main difficulty lies in switching the device from standby mode to active wireless network scanning, which isn't always intuitive without knowledge of specific key combinations.
Properly configured network connections free your computer from the need for constant physical cable connections, providing access to scanning and printing from any device in the home. It's important to understand that the stability of your device directly depends on the signal quality of your router and the correct security settings.
In this article, we'll detail all possible methods for activating the Wi-Fi module, explore software features, and troubleshoot common errors that occur during hardware synchronization. You'll learn how to confidently manage your MFP's network settings.
Preparatory stage and equipment testing
Before you begin software configuration, you must ensure that all system components are physically in good working order. Make sure that Epson L355 printer The unit is plugged into a power outlet, the control panel indicators are lit, and there is paper in the trays. A lack of essential consumables may prevent the unit from entering ready-to-use mode.
Knowing your wireless network settings is also critical. You'll need the exact network name (SSID) and Wi-Fi password. Pay attention to case: the router's security system distinguishes between uppercase and lowercase characters, so a single character error will deny the connection.
⚠️ Attention: The L355 series devices only support the 2.4 GHz frequency standard. If your router is broadcasting a 5 GHz network with the same name, try temporarily separating the networks in the router settings or moving closer to the access point, where the 2.4 GHz signal is usually more stable.
Check the distance between the router and the printer. For the initial setup, it's recommended to minimize the distance to avoid interference from walls or appliances. After successful pairing, you can move the device to its permanent location.

Resetting the printer's network settings
If the device was previously used with a different router or the settings were reset due to a power surge, a forced reset of the network settings is required. This will return the Wi-Fi module to its factory defaults, clearing the list of saved connection profiles.
To perform this operation, locate the button with an antenna or Wi-Fi icon on the control panel. Press and hold it for a few seconds until the indicators begin flashing (alternating). The exact sequence of actions is described in the model specifications.
Follow these steps to reset:
- 📶 Make sure the printer is turned on and in idle mode (not printing).
- 🔘 Simultaneously press the "Wi-Fi" button and the button with the network image (or the information button, depending on the firmware version).
- ⏱ Hold the combination for about 5-7 seconds until the power and network indicators flash simultaneously.
- 🔄 Wait until the Wi-Fi indicator starts flashing green, which indicates that it is ready for a new setup.
After reset network settings will be cleared, and the device will enter standby mode for a command from a computer or smartphone. Now you can proceed to choosing a connection method.
Why do you need to reset the settings?
A reset is necessary if the printer has “remembered” the old router and stubbornly tries to connect to it, ignoring new commands, or if the Wi-Fi password has changed and the printer cannot update it automatically.
WPS method: quick connection without entering a password
The easiest way to integrate a device into a network is to use technology WPS (Wi-Fi Protected Setup)This protocol allows you to automatically transfer a password from a router to a printer, without having to manually enter complex characters through a computer interface.
Check your router's case. Many models have a physical button labeled "WPS" or a corresponding icon (two arrows forming a circle). If there's no such button, you can activate the function through the router's web interface.
Steps to connect via WPS:
- Press the WPS button on the router and hold it for 2-3 seconds. The WPS indicator on the router should blink.
- Press and hold the Wi-Fi button on the Epson L355 printer control panel for 2 minutes.
- Watch the wireless light on the printer: it should blink and then turn solid green.
- After the indicator lights up, press the black and white or color print button to check the result.
If the printer's Wi-Fi indicator is solid, the connection has been established successfully. A computer on the same network should automatically detect the new device. If the indicator blinks continuously or remains red, repeat the process, ensuring you wait for the two-minute connection time.
Setup via Epson software
For more flexible management and installation of the necessary drivers, it is recommended to use the official software. Epson Net Setup or a full driver package available on the manufacturer's website allows you to configure the printer even if the WPS method does not work.
Download the latest drivers for your operating system (Windows or macOS) from the official support website. Run the installation file and follow the instructions in the installation wizard. When prompted for a connection type, select "Wireless" or "Wi-Fi."
During the installation process, the program will prompt you to select a setup method:
- 📡 Auto: The program will automatically find the printer on the network (the PC must be connected to Wi-Fi).
- 🔌 Via USB (temporary): The program will transfer the Wi-Fi settings from your computer to the printer via a cable, after which the cable can be removed.
- 📱 Wi-Fi Direct: creating a direct network between the device and the printer without using a router.
When you select the automatic method, the program scans the airwaves, finds your Epson L355 printer, and prompts you to enter the Wi-Fi password in a secure field. Once confirmed, the data will be transferred to the device, and it will connect to the router.
| Parameter | Description | Where to find |
|---|---|---|
| SSID (Network Name) | The name of your Wi-Fi network | On the router sticker or in the connection properties |
| Security Type | Encryption type | Usually WPA2-PSK or WPA3 |
| Password | Security key | On the router sticker (WPA/PSK key) |
| IP Address | The device's network address | Printed in the network status report |
Using Wi-Fi Direct technology
Technology Wi-Fi Direct Allows you to connect your smartphone, tablet, or laptop directly to the printer without using a home router. This is ideal for printing documents when visiting friends or in offices where network access is limited.
To activate this mode, press the Wi-Fi button on the Epson L355 control panel and hold it until the Wi-Fi Direct indicator lights up (usually a separate icon or the main indicator blinks in a specific pattern). A name like this will appear in the list of available networks on the mobile device screen. DIRECT-XX-EPSON L355.
The connection is made as follows:
- Turn on Wi-Fi Direct mode on your printer.
- On your smartphone or PC, find a network with the DIRECT prefix and the model name.
- Enter the password. By default, it is often located on a sticker under the device or on the printed configuration report.
- Once connected, you can send documents to print via the app. Epson iPrint.
⚠️ Attention: When Wi-Fi Direct is active, your mobile phone may lose internet access because it switches to the printer's local network. To access the global network, you may need to manually switch between networks.
Diagnosing and resolving connection problems
Even if you follow all the instructions, problems may still occur. If the Wi-Fi light on your printer is blinking green but printing isn't working, check to see if your antivirus or firewall is blocking the connection. This often happens. firewall perceives the printer's attempt to connect to the network as suspicious activity.
Print a network status report. To do this, turn off the printer, then hold down the information button (the "i" icon or the piece of paper with a letter on it), and turn on the device while holding the button. The report will show the IP address and connection status. If the status is "Disconnected," there's a problem with the router or the password is incorrect.
Common mistakes and their solutions:
- ❌ Authentication error: Check your keyboard layout when entering your password. Make sure Caps Lock is not enabled.
- ❌ Weak signal: If the printer is located far from the router, the data transfer speed may not be sufficient to print large photos.
- ❌ IP conflict: In rare cases, the router may assign the printer an address already taken by another device. Restarting the router resolves the issue.
If all else fails, perform a full network reset as described in the second section and try the WPS method. In 90% of cases, this restores the device to working order.
Why doesn't my Epson L355 printer detect my Wi-Fi router?
Most likely, your router only operates in the 5 GHz band, while the L355 model only supports 2.4 GHz. The issue could also be a hidden SSID (network name) or address mapping on the router.
How to find the IP address of a printer on the network?
Print a Network Status Sheet report by holding down the information button while turning on the router. The address will be listed in the IPv4 Address line.
Is it possible to connect Epson L355 to a hidden network?
Yes, but only through the Epson Net Setup software on your computer, manually entering the network name (SSID) and selecting the security type. Automatic methods (WPS) do not detect hidden networks.
What to do if the red Wi-Fi light is on?
This indicates a connection failure. Try restarting your router and printer. If that doesn't help, reset the printer's network settings and set them up again.
