The L-series all-in-one is a popular choice for home offices, but its initial setup can often be confusing for users. Wireless connection Eliminates unnecessary cables and provides access to printing from mobile devices, significantly improving ease of use. Many owners find that a standard USB cable limits mobility, and the desire to print documents directly from a phone or tablet requires a stable local network connection.
Integration process Epson L366 Connecting to your home network doesn't require extensive networking knowledge, but it critically depends on the correct sequence of steps. Mistakes when entering the password or selecting the connection method can result in the lights flashing and the computer not detecting the device. In this article, we'll cover all available configuration methods, including using WPS, manual configuration via PC and mobile applications so you can choose the most suitable option.
It's worth noting that before starting the procedure, you need to make sure the router itself is working properly and that you have a working internet connection. The Epson L366 MFP only supports 802.11 b/g/n at 2.4 GHz, so make sure your router broadcasts a network in this range.If you're using a dual-band router, make sure your computer or smartphone is connected to the 2.4 GHz network during setup, as the device may not be able to see the 5 GHz network.
Preparatory stage and reset
Before proceeding to the active configuration phase, it is necessary to prepare the software and check the physical condition of the equipment. Drivers Management utilities are the foundation without which the operating system cannot properly interact with the peripherals. It is recommended to download the full software package from the manufacturer's official website in advance to avoid the need to search for files.
If the device was previously used on a different network or the settings were changed, it's a good idea to reset the network settings to factory defaults. This will eliminate IP address conflicts and saved profiles that could prevent a new connection. To do this, press and hold the wireless and information buttons simultaneously on the control panel.
⚠️ Please note: Resetting your network settings may delete saved data about previous access points. Make sure you have the current password for your Wi-Fi network handy, as you will need to re-enter it.
Hold the indicated buttons for about 5-7 seconds until the indicators flash. After this, the printer will enter configuration standby mode. Now you can choose a connection method, which will depend on your router's capabilities and personal preferences.
WPS Method: Quick connection without password
The easiest way to integrate a device into a network is to use technology WPS (Wi-Fi Protected Setup). This method automatically transfers security settings, eliminating the need for the user to manually enter a complex password on a small screen or using buttons. However, to implement this feature, your router must support this feature and have a corresponding physical or software button.
On the control panel Epson L366 Find the button with an antenna or Wi-Fi icon. Press and hold it for 3 seconds until the network and connection lights begin flashing alternately. This indicates that the printer is searching for a WPS signal.
Within the next two minutes, press the WPS button on your router. If your router doesn't have a physical button, access its web interface through a browser and activate the WPS function programmatically. After a successful encryption key exchange, the Wi-Fi indicator on the printer will turn solid green, indicating a successful connection.
Setup via USB cable and installation wizard
If your router doesn't support WPS or has hidden this feature deep in the menu, the most reliable option is to use a USB cable for the initial configuration. This method ensures that all network settings are transferred to the printer without errors. You'll need a USB AB cable, which is usually included with the device.
Run the previously downloaded driver installation package on a computer that is already connected to the target Wi-Fi network. In the installation menu, select "Wireless Setup." The program will prompt you to connect a cable between the PC and the printer to transfer the settings.
Follow the on-screen instructions of the installation wizard. The program will automatically detect available networks and prompt you to select yours. After selecting the network and confirming your selection, the utility will transfer the SSID and password to the device, after which the cable can be disconnected.
☑️ USB Setup Preparation Checklist
Using Epson iPrint for Mobile Devices
Modern users often prefer to control their equipment from their smartphone. Application Epson iPrint It allows you to not only print documents and photos but also perform initial network module setup. This is especially convenient if you don't have a computer with a disc drive or USB port nearby.
First, connect your smartphone to the Wi-Fi network you plan to connect the printer to. Then launch the app and follow the on-screen prompts. If the printer isn't already configured, the app will prompt you to find the device and share its network settings.
In some cases, you may need to temporarily connect to the printer's own Wi-Fi signal (Wi-Fi Direct mode) so the app can "see" it and switch to your home router. This process is fully automated and takes no more than a couple of minutes.

Wi-Fi Direct Mode: Printing without a router
Function Wi-Fi Direct Allows you to create a direct connection between your device (laptop or phone) and your printer, bypassing your home router. This is ideal for situations when you need to quickly print a document while visiting someone or when your main internet connection is temporarily unavailable.
To activate this mode, press and hold the Wi-Fi button on the control panel until the Wi-Fi Direct indicator lights up. The device will print a network information page, including the network name (SSID) and password for connecting.
Connect to this network from your device using the received data. Once connected, you'll be able to print documents just like over a regular network, but the data transfer speed may be lower, and the internet connection on the connected device will be unavailable.
⚠️ Please note: In Wi-Fi Direct mode, data transfer speed is limited by the bandwidth of the direct connection. For printing large volumes of graphics or high-resolution photos, we recommend using a standard connection through a router.
What should I do if the printer doesn't see the 2.4 GHz network?
Some routers combine the 2.4 GHz and 5 GHz network names (Smart Connect). Try separating them into different names (SSIDs) in your router settings so the printer can clearly identify the desired band.
Troubleshooting and Advanced Settings
Even with proper configuration, situations may arise where the connection is unstable or completely lost. Often, the problem lies in the device dynamically changing its IP address or a weak signal at the location where the MFP is installed. To diagnose the problem, print a network status report.
Press and hold the Info button on the control panel for a few seconds. The printer will print a receipt containing detailed connection information, including IP address, subnet mask, and signal status. If the signal is weak (less than 50%), try moving the router and printer closer together.
It's also worth checking your computer's firewall and antivirus settings. Sometimes they block ports needed for the printer to be detected on the network. Adding the device to the exception list may resolve the "invisibility" issue.
Frequently Asked Questions (FAQ)
How to find the IP address of the Epson L366 printer?
The easiest way is to print a network status report by holding down the Info button. You can also find the IP address in the printer properties in Windows: Control Panel → Devices and Printers → Right-click on the Epson L366 → Printer Properties → Ports tab.
Is it possible to connect a printer to a hidden network (Hidden SSID)?
Yes, this is possible, but only through setup using a USB cable and the PC installation wizard. In manual network search mode, the printer won't detect the hidden SSID, so you'll need to manually enter the network name in the appropriate field in the installer.
Why is the Wi-Fi light orange?
An orange light usually indicates that the network module is enabled, but the connection to the router has not been established or data is not being transmitted. Check the password entered correctly and ensure the router is transmitting a signal.
Are Wi-Fi settings reset when replacing cartridges?
No, replacing ink tanks or priming the printer does not affect network settings. However, a full reset of the device (Reset All) will return all settings, including Wi-Fi, to factory defaults.
