Modern office equipment requires flexibility, and Epson L355 The MFP is a prime example of a device that combines the cost-effectiveness of inkjet printing with wireless connectivity. Connecting this MFP to a local network allows for printing documents from smartphones, tablets, and laptops without the hassle of finding extra cables. However, initial setup of the wireless module often presents difficulties for users unfamiliar with the nuances of the hardware buttons and software.
Unlike touch screen models, the controls Wi-Fi module Here, wireless network activation is accomplished through a combination of buttons on the front panel and flashing indicators. Understanding the logic behind these signals is key to successful setup. In this article, we'll cover all current wireless network activation methods, including automatic setup via WPS and manual connection via Wi-Fi Direct.
It's worth noting that connection stability directly depends on the correct router settings and the printer's firmware version. If you've previously attempted to configure the device but encountered errors, you may need to perform a preliminary setup. reset network settings to factory defaults. This is a standard procedure that eliminates IP address conflicts and invalid connection profiles.
Equipment preparation and compatibility testing
Before you start activating the wireless mode, you need to make sure that your environment is ready to work with Epson L355The device supports the 802.11 b/g/n standard, meaning it's compatible with most modern routers. However, there are important nuances regarding frequency bands. The printer doesn't support the 5 GHz band, so your router must broadcast a 2.4 GHz network.
⚠️ Important: If your router broadcasts a network with the same name (SSID) for both the 2.4 GHz and 5 GHz bands, the printer may attempt to connect to the wrong channel. In this case, we recommend temporarily separating the networks in your router settings or using WPS.
Also, make sure that the computer or smartphone from which the setup will be performed has the necessary drivers or application installed. Epson iPrintWithout software, the computer won't be able to "see" the printer on the network, even if the indicators indicate a successful connection. For mobile devices, downloading the app is a mandatory step.
Check the physical location of the device. Wi-Fi signal The signal may be weakened by metal structures or microwave ovens in the immediate vicinity. The optimal distance to the router is considered to be no more than 10-15 meters within direct line of sight, although walls also contribute to the signal loss.
WPS method: quick connection without entering a password
The easiest way to enable Wi-Fi on an Epson L355 printer is to use WPS (Wi-Fi Protected Setup). This method automatically transfers network settings from the router to the printer, eliminating the need to manually enter a complex password on a computer or smartphone keyboard. To implement this, your router must have a physical WPS button or a software interface for activating it.
The process starts with the click of a button Wi-Fi on the MFP control panel. After this, the network and signal indicators will begin flashing alternately. At this point, you have a limited time—usually about two minutes—to activate the router's search mode. Press the WPS button on the router and hold it for a few seconds until the router's security indicator begins flashing.
- 📡 Make sure the Wi-Fi light on your printer is green, which means it's ready to pair.
- 🔘 Press and hold the Wi-Fi button on the printer until the network and signal lights flash.
- ⏱️ Within 2 minutes, press the WPS button on your router.
- ✅ Wait until the printer's lights turn solid, indicating a successful connection.
If automatic connection fails, the indicators may blink with errors or go out. In this case, check whether your router supports the WPS Push-Button method, as some providers disable this feature for security reasons. It's also worth making sure that MAC address filtering isn't enabled on your router, which could block new devices.
Setting up Wi-Fi Direct for printing from a smartphone
Technology Wi-Fi Direct Allows you to create a direct wireless connection between your printer and mobile device without a router. This is ideal if you're visiting someone or in an office where access to the main Wi-Fi network is limited or requires complex web portal authorization. In this mode Epson L355 becomes an access point itself.
To activate this mode, you need to press and hold the button Wi-Fi Press and hold the Wi-Fi Direct button on the printer's control panel for approximately 5-7 seconds until the Wi-Fi Direct indicator (usually indicated by a smartphone symbol next to the antenna) lights up. Once enabled, the device will begin broadcasting a signal, the name of which (SSID) can be found on the network status report printout or on a sticker on the inside of the device.
| Parameter | Default value | Where to find |
|---|---|---|
| Network name (SSID) | EPSONXXXXXX | Condition Report / Sticker |
| Password | 12345678 | Condition Report / Sticker |
| IP address | 192.168.223.1 | Printer web interface |
| Max devices | 4 devices | User manual |
Modern Android and iOS smartphones usually warn you about this and ask whether you want to stay connected without access to the global network—you must confirm the action.
How to change Wi-Fi Direct password?
To change the default password, you must use the EpsonNet Config utility on a computer connected to the same network, or use the printer's web interface by entering its IP address in a browser.
Classic setup via USB cable and PC
If automatic methods fail, the most reliable method remains the classic setup via USB cable. This method transfers your Wi-Fi network profile directly to the printer's memory. You'll need a USB AB cable (square connector), which is usually included, and the installation disc or driver downloaded from the official website.
Run the software installation process for Epson L355When the installer prompts you to select a connection type, select "Wireless Network." At this point, the program will prompt you to connect the device via USB cable. After detecting the printer, the setup wizard will prompt you to select your network from the list of available ones and enter the password.
☑️ USB Setup Checklist
After the settings have been successfully transferred, the printer will disconnect the USB connection and attempt to connect to the network. The LEDs should light steadily. If this doesn't happen, check the event log in the installer window—it often contains an error code indicating the cause of the failure, such as invalid encryption type (WPA2/WPA3).
⚠️ Important: If using Windows 10 or 11, ensure that the Connection Manager service isn't blocking the installation of network devices. Sometimes, antivirus software may detect printer setup attempts as suspicious activity.
Reset network settings to factory defaults
In situations where the printer has “remembered” incorrect data or the router password has changed, you need to perform reset network settingsThis action will reset the network module to its original state, deleting all saved Wi-Fi profiles. This procedure often resolves issues where the lights are flashing erratically or the device is unable to detect the network.
To perform a reset on a switched-off printer, you must simultaneously press and hold two buttons: Wi-Fi and the button Information (marked with the letter "i" or a leaf icon with text). While holding them, turn on the device. Continue holding the buttons until the Wi-Fi and Wi-Fi Direct indicators flash simultaneously. Then release the buttons and wait for the module to reboot.
After resetting, the printer's network name will revert to the default (e.g., EPSON Series), and the password will be reset to the default. This is also a great way to prepare the device for sale or transfer to another user, ensuring your personal data doesn't remain on the device's memory.
Diagnosing and solving common problems
Even if you strictly follow the instructions, technical difficulties may arise. Often, the problem lies not with the printer itself, but with the network configuration. For example, if the router assigns addresses via DHCP, and the address limit is exhausted, Epson L355 It simply won't be able to obtain an IP address and won't connect to the network. In this case, rebooting the router helps.
Another common cause is incompatible security standards. If your router is configured only for WPA3 and your printer only supports WPA2, the connection will fail. You need to enter your router settings and enable mixed mode or select WPA2-PSK (AES).
- 🔴 Orange light: The printer cannot connect to the network. Check the password and network name (SSID).
- 🔴 The indicator flashes red and green: Hardware error or critical firmware failure.
- 🟢 The indicator flashes green: The connection or data transfer process is in progress.
- 🟢 The indicator is green: Successful connection to the network.
If you're using a hidden network (SSID is hidden), automatic detection won't work. You'll have to manually enter the network name through the setup menu or use WPS. Also, make sure your router doesn't limit the number of connected devices, which is common in hotel networks or corporate environments.
What should I do if my computer can't see my printer on the network?
Check whether the devices are on the same subnet. It's common for the computer to be connected to the router's guest network, while the printer is connected to the main network. Also, try temporarily disabling Windows Firewall or antivirus software to ensure that printing ports aren't blocked.
Can Epson L355 be connected to a 5GHz network?
No, the L355 model is equipped with a module that operates exclusively in the 2.4 GHz band. If your router combines both bands into a single network, try temporarily disabling the 5 GHz band in the router settings or separating the network names (SSIDs) for the different frequencies.
How to find out the printer's IP address after connection?
The easiest way is to print a network status report. To do this, turn off the printer, then press and hold the "i" (information) button and the power button simultaneously until the lights flash. The printer will print a page with the current IP address listed in the Network section.
Do I need to remove the USB cable after setup?
Yes, if you configured the device via USB, you must disconnect the cable after the process is complete. If the cable remains connected, the operating system may continue to treat the printer as a local device and will not send print jobs over the network.
