Modern inkjet multifunctional devices (MFPs) have long ceased to be just peripherals requiring a mandatory physical connection to a computer. Model Epson L355 It has become a true bestseller thanks to its continuous ink supply system and, crucially, its built-in wireless module. The ability to print documents and photos directly from a smartphone or laptop without the hassle of cables significantly improves the convenience of using this device in homes and small offices.
However, the initial wireless activation process often presents difficulties for users unfamiliar with network protocols. Unlike simpler models, a precise sequence of steps is required to ensure the device correctly connects to the router. In this article, we'll detail all possible connection methods, address common errors, and help you set up stable printer operation on your local network.
Before proceeding with the software, you need to ensure the hardware is physically ready. Make sure the ink is in the system, the printer is plugged in, and within range of your router's signal. If you just unpacked the device, don't rush to run the installation disc—it may contain outdated driver versions.
Preparing for installation: checking hardware and drivers
The first step is to ensure your software is up-to-date. Drivers included on the included disc are often dated based on the model's year of manufacture, while modern operating systems require more recent versions for proper network protocol operation. Download the full driver and utility package. Epson L355 from the manufacturer's official website, choosing your version operating system.
It's also important to check the status of your network equipment. The router must be turned on and broadcasting the network. If you plan to use the WPS method, make sure the router has a corresponding button. In some cases, providers provide complex gateways where Wi-Fi functionality may be disabled or hidden, so basic network diagnostics are essential.
To install the software, unzip the downloaded archive and run the setup file. During installation, the program will prompt you to select a connection type. If you select a wireless connection, the setup wizard will ask you to temporarily connect the device via USB cable to transfer network settings. This is the standard and most reliable procedure for initial configuration.
WPS method: quick connection without entering a password
Technology WPS (Wi-Fi Protected Setup) allows you to connect devices to a network without having to manually enter a complex password. This is ideal if you don't want to mess with settings or if you've forgotten your network's access key. However, it's important to note that this method only works if your router supports this feature and it's enabled.
To begin setup, press the WPS button on your router. It's usually marked with a corresponding icon or two arrows forming a circle. After pressing it, you have about two minutes to activate search mode on the printer itself. On the control panel Epson L355 Find the button with the image of a smartphone or the Wi-Fi icon.
⚠️ Attention: If the Wi-Fi indicator on the printer is flashing green and orange simultaneously, this means the connection is not established. Make sure you press the WPS button on the router before activating the mode on the printer.
Press and hold the Wi-Fi button on the printer until the lights begin flashing alternately. The device will then automatically find the router and establish a connection. A successful connection is indicated by a solid green Wi-Fi light. This method is especially convenient when connecting to mobile devices, where entering characters on the virtual keyboard can be difficult.
Setup via USB cable: the classic way
The most stable and expert-recommended method is configuration via a temporary USB connection. This method ensures that all necessary network parameters, including encryption type and addressing, are transferred without the risk of manual entry errors. You will need a high-quality USB Type-AB cable, which is usually included in the kit.
Run the previously downloaded driver installer. When prompted to select a connection type, select "Wireless Network." Follow the on-screen instructions: the installer will ask you to connect the printer to your computer via a cable. At this point, data exchange occurs, and the program automatically reads the list of available networks and transmits your router password to the selected network.
After the settings are successfully transferred, the program will notify you that the cable can be disconnected. The printer will overwrite the internal network settings and enter Wi-Fi connection standby mode. If your home network list includes multiple networks (for example, 2.4 GHz and 5 GHz), select the one that operates in the 2.4 GHz band, as the module Epson L355 may not support modern 5 GHz frequencies.
| Parameter | Meaning for L355 | Note |
|---|---|---|
| Wi-Fi standard | 802.11 b/g/n | Supports 2.4 GHz only |
| Encryption type | WPA2-PSK | The safest standard |
| WPS mode | Supported | Button or PIN |
| Mobile printing | Epson iPrint | An app is required |
Manually configure IP address and network settings
In corporate networks or if the router has complex settings, manual registration may be required. IP addressesThis allows you to assign a printer to a specific address so that the computer always "sees" it, even after a hardware reboot. To do this, you must first check the current network status by printing a connection report.
To obtain a report, turn off the printer. Then, press and hold the wireless button and the information button (the "i" icon) simultaneously, then turn on the device while holding them. The printer will produce a technical data sheet, which will show the current IP address, subnet mask, and gateway. This information is required for manual configuration in the operating system.
192.168.1.100 (IP address example)255.255.255.0 (Subnet mask)
192.168.1.1 (Default Gateway)
If automatic address acquisition (DHCP) isn't working correctly, you can specify a static address using the Epson Net Config utility or directly in your computer's TCP/IP settings. Make sure the address you select is in the same subnet as your router but doesn't overlap with other devices' addresses to avoid confusion. IP conflict.
Why doesn't the printer see the 5 GHz network?
The wireless module in the L355 model is single-band and operates exclusively in the 2.4 GHz frequency range. Modern routers often group networks under a single name, which can cause confusion. It is recommended to temporarily separate the networks in the router settings or ensure the device is connected to the 2.4 GHz guest network.
Connecting to mobile devices and Epson iPrint
One of the main advantages of the model Epson L355 The ability to print directly from smartphones and tablets is available using a proprietary app. Epson iPrint, available for iOS and Android. The app not only lets you print documents but also scan images, sending them directly to the cloud or your phone's gallery.
To get started, make sure your mobile device and printer are connected to the same Wi-Fi network. Launch the app and tap "Select Printer." If the device is found on the network, it will appear in the list. If the printer isn't detected, check your router's firewall settings—sometimes they block new devices from discovering local devices.
⚠️ Attention: When printing large photo files over Wi-Fi, speeds may be lower than with a wired connection. This is normal for wireless printing, especially if the signal is weakened by walls or other obstacles.
There is also a mode Wi-Fi Direct, which allows you to connect to the printer directly, without a router. To activate this mode, press the corresponding button on the control panel. The phone will see the printer as an access point, but in this mode, it will not have internet access while the direct connection to the MFP is active.
Diagnosing problems and resetting network settings
If none of these methods help, or the printer suddenly stops responding over the network, it's a good idea to reset the network settings to factory defaults. This will clear saved Wi-Fi profiles and passwords, returning the network module to its original state. To do this, turn off the device, then simultaneously press and hold the wireless button and the cancel button (the triangle in a circle).
Turn on the printer without releasing the buttons until the lights flash. Then, repeat the setup process again. Another common issue is incompatibility of security standards: if the router is configured only for WPA3, the old printer may not connect. In this case, you should enable mixed WPA2/WPA3 mode in the router settings or temporarily switch to WPA2.
☑️ Network Diagnostic Checklist
Keep in mind that router and operating system software is constantly being updated. Configuration interfaces may change, and older protocols may be blocked by new security updates. If you use a complex network infrastructure, check the encryption protocol requirements in the documentation for your network equipment.
Frequently Asked Questions (FAQ)
Can the Epson L355 be connected to a hidden Wi-Fi network?
Yes, this is possible, but only through manual configuration via a USB cable or through the printer's menu (if the model allows entering an SSID). Automatic methods, such as WPS, don't work with hidden networks, as the router doesn't broadcast its name for discovery.
Why does my printer print very slowly over Wi-Fi?
Wireless printing speed depends on signal quality and channel congestion. If the router is located far away or microwaves or other 2.4 GHz devices are nearby, data transfer speed will drop. Try moving the router closer to the printer.
How do I find out the IP address of my printer if it doesn't print a report?
You can find the IP address using the Epson Status Monitor program installed along with the drivers on your computer. The address is also often displayed in the list of connected clients in your router's web interface (LAN or DHCP Client List section).
Does the L355 support Epson Connect cloud printing?
The L355 model has basic network support, but a firmware update may be required to use Epson Connect cloud services. However, functionality may be limited compared to newer L-series models.
