2. Press the button within 2 minutes WPS on the router. It's usually located on the back panel and labeled.
3. Wait for the indicator Wi-Fi the printer won't light up blue (this means successful connection).
4. Print a network settings test sheet by pressing and holding the button Information (ⓘ) for 5 seconds.

If the indicator flashes orange for more than 5 minutes, the network was not found. Check that the router is broadcasting in the 2.4 GHz band, not 5 GHz, and try again.

Setting up via the printer panel: manual input of parameters

If WPS If the network connection is unavailable or has failed, you can enter the network settings manually through the printer menu. This method requires precise input. SSID (network name) and password. Here are the step-by-step instructions:

1. Press the button on the printer Home (🏠), then select Settings (⚙️) → Wi-Fi settings.

Optimizing your router for stable printer operation

Even if the printer is connected, problems may arise over time: connection drops, slow printing, or the device may not be detected. This is most often due to router settings. Recommended settings for Epson L3151:

• 📶 Wi-Fi range: only 2.4 GHz (turn off 5 GHz or separate networks).
• 🔢 Wi-Fi channel: select a fixed channel (eg. 6 or 11), and not Auto.
• 🔒 Security type: WPA2-PSK (AES) (do not use TKIP or WEP).
• 📡 Signal strength: set to 100% (Some routers have a power limiting option).
• 🔄 Opening hours: 802.11n (turn off 802.11ac, if it is enabled).

If your printer is located far from your router, consider the following options:

• 📶 Use Wi-Fi repeater (repeater) to amplify the signal.
• 🔌 Connect the printer to the router via Powerline adapter (data transmission via electrical wiring).
• 🖧 Set up static IP address for the printer in the router to avoid DHCP conflicts.

How to set up a static IP for a printer?

1. Find the MAC address of the printer (on the network settings sheet).

2. Log in to the router's web interface (usually 192.168.1.1 or 192.168.0.1).

3. Go to the section DHCP → Address Reservation (or IP-MAC binding).

4. Add a new rule: specify the MAC address of the printer and the desired IP (for example, 192.168.1.100).

5. Save the settings and reboot the router.
