Modern printing devices have long ceased to be bulky devices that require a mandatory cable connection to a computer. Wireless technology has become the standard for printing documents and photos directly from a smartphone or laptop from anywhere in the apartment. The model Epson L366 is one of the most popular representatives of the EcoTank series, combining an economical CISS and the ability to work online.
However, initial setup often presents difficulties for users accustomed to simpler solutions.

For the Epson L366 to work correctly, the router must support the 802.11 b/g/n standard at a frequency of 2.4 GHz., as this model doesn't detect 5 GHz networks. This is a critical point that is often overlooked by owners of modern dual-band routers.
Equipment preparation and compatibility testing

Frequently Asked Questions (FAQ)
Can Epson L366 be connected to a 5GHz network?
No, the L366 model only supports the 802.11 b/g/n standard, which operates in the 2.4 GHz band. If your router is dual-band, make sure the 2.4 GHz network is active and has a separate name (SSID), or that compatibility mode is enabled.
What to do if the orange Wi-Fi light is on?
A flashing orange light usually means the connection is in progress or an error has occurred. If it's constantly on, check your signal strength. If it's flashing along with the green light, data is being transmitted. If it's flashing only orange, there's no connection.
Do I need to turn off my computer to print over Wi-Fi?
No, the computer doesn't have to be turned off. The printer connects directly to the router and has its own network address. You can print from any device (phone, tablet, or another laptop) as long as the printer is plugged in.
How to find the IP address of a printer on the network?
Press and hold the information button (letter i) on the printer's control panel for about 7 seconds. The device will print a network status report, which will show the IP address, MAC address, and connection status.
