Preparing for connection: what you need to check before you start

Before you begin setting up, make sure the following basic requirements are met:

• 📶 The router is turned on and distributes Wi-Fi in the range 2.4 GHz (the printer does not support 5 GHz). The network name (SSID) must be visible (not hidden).
• 🔌 The printer is turned on and is located within 1–2 meters of the router (for initial connection). Make sure there's enough ink in the tanks—if there isn't enough, some menu functions will be blocked.
• 💻 Computer or smartphone Already connected to the same Wi-Fi network you plan to connect the printer to. This will be needed for driver installation and testing.

If your router is in the mode 802.11n/ac (or newer standards), temporarily switch it to compatibility mode 802.11b/g/nThis will solve the problem of the network being "invisible" to the printer. This can be done in the router's web interface (usually at 192.168.0.1 or 192.168.1.1) in the section Wireless Settings → Mode.

⚠️ Attention: If your router uses guest network or functions like "Wi-Fi Direct", printer Epson L3156 won't be able to connect to them. Use the main network with a password.
