If you already have experience setting up network devices, you can skip straight to section with step-by-step instructionsWe recommend that beginners read the entire article—it will save time searching for solutions to potential problems.

What you need to connect

Before starting the setup, please check that you have all the necessary components:

• 📱 Smartphone on Android (version 6.0+) or iOS (version 12+). Older OS versions may not support modern printing protocols.
• 🖨️ Epson L3150 With Wi-Fi enabled. Make sure the printer is not connected to the computer via USB during setup.
• 📶 Router with standard support 802.11b/g/n at 2.4 GHz. The printer does not work with 5 GHz networks!
• 🔌 Printer power supplyWi-Fi setup is only possible when the device is turned on.
• 📄 Documents for printing (photo, PDF, Word) - they will be needed to test the connection.

If you don't have access to a router (for example, you're in an office or hotel), use the mode Wi-Fi DirectIn this case, the printer itself distributes the network, and the phone connects to it directly. The downside of this method is that printing is only possible from one device at a time.

Important! Epson L3150 Doesn't support connecting to hidden Wi-Fi networks (where the SSID isn't broadcast). If your router is configured this way, temporarily disable hiding the network name in its settings.

Setting up a router for a printer

Printer Epson L3150 compatible with networks only 2.4 GHzIf your router operates in dual-band mode (2.4 + 5 GHz), you must:

2. Go to section Wireless network (Wi-Fi) or Wireless Settings.
3. Make sure the network 2.4 GHz is turned on and has a unique name (SSID).
4. Set a password (recommended) WPA2-PSK with AES encryption).

Some modern routers (for example, ASUS RT-AX88U or TP-Link Archer C6) by default, they combine 2.4 and 5 GHz networks under one name. In this case:

• 🔧 Turn off the feature Smart Connect or Band Steering in the router settings.
• 📡 Give the 2.4 GHz network a separate name (e.g. MyWiFi_2G).
• 🔒 Set the same password for both networks so that devices switch automatically.

Warning: If your network uses MAC address filtering, add the printer's MAC address to the list of allowed devices. Find the MAC address Epson L3150 you can, by printing it out Network report from the printer control panel (button Information → Print report).

Wireless Printing Security

Wi-Fi printing is convenient, but it poses a risk of data leakage. Follow these recommendations:

• 🔐 Use a complex Wi-Fi password (at least 12 characters with numbers and special characters).
• 📡 Turn off WPS on the router - this protocol is vulnerable to hacking.
• 🖨️ After printing confidential documents, clear the print queue on your printer (Settings → Memory Cleanup).
• 📱 On your phone, disable automatic connection to open Wi-Fi networks.

If the printer is used in an office:

• Set up access control by MAC addresses in the router.
• Turn it off guest access to the network where the printer is connected.
• Update your printer firmware regularly (every 3-6 months).

For additional protection, you can enable data encryption in the print settings (in the application Epson Smart Panel select Settings → Secure Print). In this case, documents will be transmitted in encrypted form.
