The situation when the MFP Epson L355 Stopping detecting the wireless network or losing connection to the router is one of the most common problems with printing equipment. Often, the cause lies not in a device malfunction, but in corrupted configuration files or changes to the router's security settings. Users often notice a blinking Wi-Fi indicator, which signals the need to adjust the equipment's settings.
Restoring functionality requires performing a reset procedure, which will return the network module to factory settings. This action does not affect printing or scanning settings, but completely clears the memory of previous connections. It is important to understand, that after performing this operation you will have to re-enter the password for your home network.
This article describes in detail the algorithm of actions for the model L355, given the specifics of its hardware interface. We'll cover both software methods via utilities and a hardware reset using buttons, which is especially important if the printer is out of reach of the PC. Correctly following these steps ensures successful reintegration of the device into the local network.
Reasons for connection loss and the need to reset
Before resorting to radical measures, it is necessary to analyze the reasons why wireless module could have failed. Often, the problem lies in a router firmware update, when encryption standards or frequency ranges change. The device Epson L355, released several years ago, may not work correctly with newer WPA3 security protocols, requiring a reset to default settings.
Another common cause is an IP address conflict. If you have a large network, the printer may have received an address already taken by another device, or the router's DHCP server may have stopped assigning a new one. In such cases, reset network settings Forces the process of requesting a new address, which often solves the problem of printing freezing.
Physical wear and tear or temporary electronic malfunctions should also be considered. Static electricity or power surges could have damaged the network adapter's memory buffer. In this case, a software reset acts as a "reboot" for the microcontroller responsible for Wi-Fi, clearing any accumulated errors.
⚠️ Important: Before resetting, make sure you know the exact password for your Wi-Fi network. After the reset, it will be deleted from the printer's memory, and without it, reconnecting will be impossible.
Hard reset via Wi-Fi button
The fastest way to return Epson L355 To reset the network settings to factory defaults, use a combination of buttons on the front panel. This method doesn't require a computer and works even if the drivers aren't installed correctly. The main tool here is the button. Wi-Fi, located on the control panel.
To perform a reset, press the Wi-Fi button and, while holding it down, press the black-and-white print button (usually marked with a monochrome sheet symbol). Hold both buttons for a few seconds until the lights begin flashing simultaneously. This indicates that the initialization process has begun.
Once the Wi-Fi and network indicators begin flashing, you can release the buttons. The device will reboot the network module. The Wi-Fi indicator should begin flashing green and orange alternately, indicating it is in setup or connection standby mode. If the indicators are off, the Wi-Fi module may be disabled by software.
☑️ Checking for readiness for reset
Reset via EpsonNet Print Server
If physical access to the buttons is difficult or you prefer control from a PC, you can use the utility EpsonNet Print ServerThis program is included with the driver package and allows you to manage the printer's network settings remotely. Launch the program from the Start menu in the folder Epson.
In the window that opens, select your printer. Epson L355 from the list of available devices. If the printer shows as "Not connected," try clicking the refresh list button. Go to the tab Configuration or Network, where the TCP/IP and wireless connection settings are located.
Find the button or link with the title Reset or InitializeThe system will ask for confirmation of the operation. After confirmation, the printer will send a command to reset the network card. The computer may temporarily lose connection with the device, which is normal.
⚠️ Note: The EpsonNet interface may differ depending on your Windows or macOS operating system. If you don't find the required button, try running the program as an administrator.
Using EpsonNet Config for advanced customization
A more advanced tool is the utility EpsonNet Config, which provides access to hidden network adapter settings. It allows you to not only reset the settings but also force an IP address assignment if automatic assignment isn't working. Download the utility from the manufacturer's official website if it wasn't installed with the drivers.
After launching the program, find your printer in the list. If the device is online, its status will be green. Select the device and go to the menu. Configuration. Here you are interested in the tab Protocol or TCP/IPThere is often a button at the bottom of the window. Default or Initialize.
Usage EpsonNet Config This is especially effective when the printer is stuck on an old IP address and refuses to accept a new one from the router. Resetting the printer with this utility clears the DNS cache and routing tables within the printer itself, which often resolves issues in complex corporate or smart home networks.
| Parameter | Value before reset | Value after reset | Impact on work |
|---|---|---|---|
| IP Address | Static or legacy DHCP | 0.0.0.0 (waiting) | The printer is no longer visible on the network. |
| SSID Profile | Your network name | Empty | Re-binding required |
| Security Key | Saved password | Removed | Data security |
| MAC Address | Unique ID | It doesn't change | The identifier remains the same |
What should I do if EpsonNet Config doesn't see my printer?
If the utility doesn't detect the device, try temporarily disabling Windows Firewall or antivirus software. Also, make sure the computer and printer are on the same subnet (the first three digits of the IP address should match, for example, 192.168.1.X).
Resetting Wi-Fi after a reset
After a successful reset network settings The printer goes into connection standby mode. The Wi-Fi indicator will start flashing. At this point, you need to reconnect the device to the router. The easiest way for this model L355 - using WPS technology, if your router supports this function.
Press the WPS button on the router, then the Wi-Fi button on the printer. The devices should automatically find each other and exchange encryption keys. If you're not using WPS, you'll need to run the driver installer on your computer. Select "Change connection" or "Set up a wireless connection."
During the installation process, the program will prompt you to select your network from the list and enter the password. Make sure you select a network with a frequency 2.4 GHz, as many older printer models, including the L355, do not support the range 5 GHzAfter entering the data, the Wi-Fi indicator should light up solid green.
Diagnostics of status indicators
Understanding the indicator light signals is critical for diagnosis. Indicators on the panel Epson L355 They communicate the module's status more accurately than any messages on a computer screen. Green typically indicates normal operation, orange indicates caution or an error, and blinking indicates data transfer or waiting.
If the Wi-Fi indicator remains orange or rapidly flashes both colors after the reset, this may indicate a connection error. The password may have been entered incorrectly, or the signal strength may be too weak. In this case, repeat the reset procedure and ensure the printer is no more than 5-7 meters from the router, with no physical obstructions.
Sometimes the lights go out completely. This could mean the Wi-Fi module has entered sleep mode to save power, or there's been a power failure. Try turning the printer off with the power button, waiting 10 seconds, and then turning it on again. If the issue persists, the device's firmware may need to be updated.
Why can't my printer see my 5GHz network?
The Epson L355 is equipped with an 802.11 b/g/n Wi-Fi module, which operates exclusively in the 2.4 GHz frequency range. Modern routers often combine the 2.4 and 5 GHz bands under a single network name. The printer simply "doesn't see" the higher-frequency part of the spectrum. Solution: separate the networks in the router settings, giving them different names (for example, HomeWiFi and HomeWiFi_5G), and connect the printer to the network without the 5G adapter.
Is it possible to reset the settings without losing the page counter?
Yes, resetting network settings only affects Wi-Fi and local network connection settings. The page counter, print quality settings, print head calibration, and ink level data are stored in a different memory location and remain unchanged. You will only lose saved Wi-Fi profiles.
What to do if the Wi-Fi button does not respond?
If pressing the Wi-Fi button doesn't produce any response (the lights don't light), check to see if the control panel is locked. In some standby modes, the buttons may not work. Try printing a test page. If the printer prints but doesn't respond to the Wi-Fi button, the control panel cable may be damaged or a more thorough service reset is required using the power and paper feed button combination (but this risks resetting the entire printer).
Do I need to remove the old printer from Windows before resetting?
Removing the device from the Devices and Printers list in Windows before resetting is not required, but it is recommended. After resetting and reconfiguring, Windows may see the printer as a "New Device" with a duplicate name (e.g., Epson L355 (Copy 1)). To avoid confusion, it's best to remove the old shortcut after ensuring the new one is working correctly.
