Setting up wireless printing on an Epson L366 with a Keenetic router

Organizing a home local network often presents users with the task of uniting various devices into a single ecosystem, where each gadget is accessible from any computer or smartphone. Epson L366 is one of the most popular inkjet multifunctional devices, which was originally designed for network operation thanks to its built-in Wi-Fi module. However, the initial pairing process of the printer with routers of the line Keenetic may cause difficulties for inexperienced users due to differences in WPS algorithms and manual IP address configuration.

A successful connection depends on correctly entering network security parameters and selecting the correct operating mode for the printer itself. Unlike a wired USB connection, a wireless connection requires careful verification of encryption settings and frequency range, as many older printer models do not support modern security standards or the 5 GHz frequency. Therefore, it's important to follow each step of the instructions carefully to avoid address conflicts in the future.

In this guide, we'll cover two main integration methods in detail: automatic integration via a secure connection and manual integration via Epson utilities. You'll learn how to reserve a static IP address in the router interface, ensuring stable printing even after a hardware reboot. It is critical to use the 2.4 GHz band for this device, as the Wi-Fi module in the Epson L366 does not physically support 5 GHz networks.

Equipment preparation and compatibility testing

Before you start the configuration, you need to make sure that your router Keenetic The Epson L366 printer itself is fully charged and in good working order. Make sure you know the password for your Wi-Fi network, as you'll need it to enter the printer menu or configure it from your computer. It's also recommended that the computer you'll be using for configuration be connected to the router via a cable or the same Wi-Fi network you plan to connect the MFP to.

It's worth noting that the wireless module in the L366 model operates exclusively in the 2.4 GHz frequency range. If your Keenetic router is configured to operate only in 5 GHz mode or uses "Smart Connect" mode (network name aggregation), you may experience difficulties detecting the device. In this case, we recommend temporarily separating the networks or forcing the computer to use the 2.4 GHz band for the initial setup.

⚠️ Important: Make sure that Client Isolation is not enabled on your router, otherwise devices on the Wi-Fi network will not see each other and printing will be impossible.

For a smooth user experience, you may need the installation disc included with your device or access the manufacturer's official website to download the latest drivers. Modern operating systems often detect the device automatically, but for full functionality of both the scanner and printer, it's best to use the manufacturer's software. Also, check that the Wi-Fi indicator on the printer's control panel is lit: if it's blinking, the device is ready for setup; if it's solid, it's already connected.

Automatic connection via WPS technology

The fastest way to establish a connection between the router Keenetic and a printer Epson L366 The most common method is to use WPS (Wi-Fi Protected Setup) technology. This method allows you to transfer network security settings automatically, eliminating the need to manually enter a complex password on a small screen or via printer buttons. Keenetic routers typically have a physical button with a corresponding label or Wi-Fi icon on the body, which activates the device search mode.

To start the process, press and hold the WPS button on the Keenetic router for a few seconds until the Wi-Fi indicator starts flashing, indicating pairing mode. Immediately afterward, within two minutes, press and hold the Wi-Fi button on the Epson L366 printer's control panel until the network and Wi-Fi Direct indicators begin flashing alternately. The device will then attempt to find and connect to the network automatically.

• 🟢 The Wi-Fi indicator is constantly on - the connection is successful.
• 🔴 The Wi-Fi indicator is blinking - the connection process is in progress or the network is being searched for.
• ⚪ Wi-Fi indicator is off - the wireless module is disabled or an error has occurred.

If automatic connection doesn't occur on the first try, the connection timeout may have expired or the WPS function may be blocked in the router's security settings. In the Keenetic interface, check whether WPS is enabled and whether there's a time limit on new connections. Sometimes, moving the printer closer to the router during setup can help to prevent data packet loss due to a weak signal.

Setting up via the Epson Net Setup utility

In cases where the automatic method does not work, the most reliable option is to use a specialized utility Epson Net Setup, which is included in the complete driver package. This software tool allows you to detect the printer, even if it's temporarily connected via USB, and transfer its Wi-Fi network settings. First, connect the MFP to your computer via USB and run the software installation from the disc or downloaded file.

During the installation process, select the "Wireless Network" connection type. The program will prompt you to select a setup method: automatic or manual. Select the manual method if the automatic method doesn't find the router. The utility will prompt you to select your network from a list of available SSIDs and enter the password. After entering the data, the program will transfer it to the printer via USB, after which you can disconnect the cable.

It's important to select the correct network profile in the setup wizard. If you have a guest network or a network for IoT devices, make sure you configure the printer to the primary profile, which has no restrictions on local data exchange. After setup is complete, the utility will prompt you to print a connection report, which will show the IP address and connection status, confirming successful integration.

Reserving an IP address in the Keenetic interface

For stable printer operation on a network, especially if it is accessed by multiple computers, it is crucial to assign a permanent IP address to the device. Routers Keenetic By default, addresses are assigned dynamically via DHCP, and when the printer is rebooted, its address may change, leading to loss of connectivity with computers. To avoid this, you need to configure a static binding in the router's web interface.

Open your browser and enter your router's address (usually 192.168.1.1 or my.keenetic.net), then log in. Go to the section My Networks and Wi-Fi and find the list of connected clients (often located under "Home Network" or "Client List"). Find your Epson device in the list (it may be listed as EPSONXXXXXX or by its MAC address, which can be found by printing a network report on the printer itself).

Once the device is detected, click on it or the edit icon (often a lock or gear icon) and select "Permanent IP Address" or "Reserve Address." Enter the desired address manually (e.g., 192.168.1.200) so that it doesn't overlap with the dynamic IP range, or confirm the current one. Save the settings, and the router will always assign the same IP address to the printer.

Installing drivers and adding a device in Windows

Once the printer has a permanent address on the network, you need to add it to your computer's operating system. In Windows 10 and 11, this process is automated, but older versions or specific configurations may require manual addition. Go to Settings → Devices → Printers & Scanners and click "Add a printer or scanner".

If the system finds a device named Epson L366, simply select it and click "Add." If the search returns no results, click the link "The printer you want is not listed." In the window that opens, select "Add a printer by its TCP/IP address" and enter the reserved IP address you set in the Keenetic router (e.g., 192.168.1.200).

• 🖨️ Select "Special device" in the device type.
• 🔢 In the "Name or IP address" field, enter a static IP.
• 📦 Check the box "Query the printer and automatically select a driver."

Windows will attempt to connect to the device at the specified address. If a connection is established, the system will prompt you to install a driver. You can select one from a list of manufacturers (Epson) and models (L366 Series) or provide the installation file manually. After installation is complete, it is recommended to print a test page to ensure data is transferred correctly and without delay.

Diagnosis and solution of typical problems

Even with careful setup, situations may arise where the printer stops responding or displays the "Offline" status. This is often due to security protocol updates or changes to router settings. If the printer's Wi-Fi indicator is blinking but no printing occurs, try resetting the network settings on the MFP itself: press and hold the Wi-Fi button and the Cancel button (the cross) simultaneously for a few seconds until the indicators blink.

⚠️ Note: The Keenetic router interface may be updated, changing the layout of menu items. If you don't see the options described, please consult the official documentation for your firmware version.

Another common issue is a conflict with SMB protocol versions or blocked ports by an antivirus program. Ensure that the Windows Firewall allows access for the Epson app and that the network is marked as "Private" and not "Public." Windows blocks device discovery by default on public networks.

If all else fails, it's a good idea to perform a full reset of the printer's network settings and repeat the process from the beginning, paying particular attention to the password you enter. Remember that case is important, and some special characters in the password may not be processed correctly by older printer firmware.
