Switching to wireless connectivity for office equipment isn't just a passing fad, but a genuine necessity for creating a comfortable workspace. Epson L366 MFP supports the standard Wi-Fi Direct and a classic router connection, allowing you to print from laptops, smartphones, and tablets without the hassle of wires. However, initial setup often presents difficulties for users unfamiliar with network protocols.
The main difficulty is that the printer does not have a full screen for entering a password, so all operations have to be performed through button combinations or a temporary USB connection. Wireless network This requires precise steps, otherwise the device simply won't detect your router. In this article, we'll cover all available methods, including WPS and manual IP address configuration.
Before you begin setup, make sure your router is turned on and providing internet access, and your printer is filled with ink and ready to use. Signal stability Directly impacts print speed and network scanning capabilities. If you plan to use the device in an office with a large number of connections, proper configuration is critical.
Equipment preparation and compatibility testing
The first step is physical preparation peripheral deviceMake sure the MFP is plugged in and within range of your router's signal. The distance should not exceed the standard limits for the 2.4 GHz band, as Epson L366, like most budget models, operates at this frequency. The presence of concrete walls or metal structures can significantly weaken the signal.
You also need to know the parameters of your home network. You will need the network name (SSID) and the Wi-Fi password. If the password is too complex or contains special characters that are difficult to enter using the printer's buttons, it's better to use the WPS method or a temporary cable connection for the initial setup. This will save time and frustration.
It's important to check if Client Isolation is enabled on your router. This security feature prevents data exchange between devices within the same network, making it impossible to print from your computer. Make sure your router's frequency range is set to 2.4 GHz, as the printer does not support 5 GHz networks.
⚠️ Note: Router interfaces and drivers are subject to update. If the menu items described differ, please consult the official documentation from your router manufacturer.

5. Enter your Wi-Fi password
6. Disconnect the cable after confirmation
This method is good because it minimizes the human factor. Software It will automatically check the compatibility of the parameters and display an error if something goes wrong, which is much more convenient than guessing based on the blinking lights.
☑️ Check before installing drivers
Manually configuring IP addressing and network parameters
In corporate networks or with complex router settings, manual registration may be required. IP addresses. By default The Epson L366 receives an address automatically via DHCP, but a static IP will make it easier to find on the network and prevent address conflicts.
First, you need to find out the printer's current IP address. This can be done by printing a network status report. Press and hold the wireless button on the control panel until the light starts flashing, then press the button with the image of a sheet (black and white copy) or the button combination specified in the instructions for your firmware version.
In the printed report, find the line IP Address. If it is indicated there 0.0.0.0 or 169.254.x.x, then the printer hasn't received an address from the router. In this case, check the DHCP settings on the router. If the address is present, enter it in the address bar of your computer's browser to access the web interface (if the model supports Epson Net Config) or use the utility. Epson Net Config.
| Parameter | Default value | Recommended value |
|---|---|---|
| IP acquisition mode | Auto (DHCP) | Auto (DHCP) |
| Communication protocol | IPv4 | IPv4 |
| SSID (Network Name) | - | Your network is 2.4 GHz |
| Security mode | - | WPA2-PSK (AES) |
Using a static IP address is especially useful if you frequently change printing devices. Your computer will always know where to find the printer, even after rebooting your router, as long as the address range is configured correctly.
What to do if the IP address is not assigned?
If the printer isn't receiving an IP address, try temporarily disabling MAC address filtering on your router. Also, make sure there are still free addresses in the DHCP address pool. Sometimes, rebooting the router with the printer still connected can help.
Using Wi-Fi Direct to print from mobile devices
Function Wi-Fi Direct allows you to connect smartphones and tablets directly to the printer, bypassing the router. This is ideal for quickly printing photos or documents from your phone when the main Wi-Fi network is unavailable or congested.
