In this article, we'll cover all the details of connecting your device to a router and mobile devices running Android and iOS. You'll learn how to avoid common mistakes and ensure maximum data transfer speeds.
Before you begin, make sure your router is operating on the standard 2.4 GHz band, as this printer model does not support modern 5 GHz networks. a critical technical nuance, which, if ignored, most often results in the phone failing to detect the device. Preparing the equipment will only take a couple of minutes, but will save hours of troubleshooting down the road.
Equipment preparation and compatibility testing
The first step is to physically prepare the device for wireless operation. Plug the MFP into a power outlet and wait for the self-test cycle to complete, when the carriage moves and stops. The power indicator on the control panel will light, and the Wi-Fi button will begin blinking, indicating it's ready for setup.
Make sure your smartphone is connected to the same Wi-Fi network you plan to connect the printer to. If you're using a dual-band router, temporarily switch your phone to the 2.4 GHz network, as Epson L3151 It doesn't see the 5 GHz network. This is a common problem faced by owners of new routers.
- 📱 Charge your smartphone to at least 40% to prevent the screen from turning off during the setup process.

Solution and connection diagnostics
Even with proper setup, situations may arise where the phone "doesn't see" the printer or printing freezes. Most often, the problem lies in the devices being on different subnets or blocked by router security settings. Check if AP client isolation is enabled in the router settings.
If the printer shows as "Offline," try restarting the router, printer, and phone. A simple power cycle often helps, as it clears the DNS cache and refreshes IP addresses. Also, make sure your phone isn't in "Data Saver" mode, which can block network device searches.
- 🔄 Reset your printer's network settings if it has changed its IP address.
- 📶 Check that your phone and printer are connected to the same frequency band (2.4 GHz).
- 🔥 Disable your antivirus or firewall on your phone during diagnostics.
- 📲 Reinstall the Epson iPrint app if it freezes at the search stage.
⚠️ Note: If you've changed your router or Wi-Fi password, the printer won't connect automatically. You'll need to re-configure the network, as the device only remembers the old settings.
In some cases, static IP addressing can help. By accessing the router's web interface, you can reserve an IP address for the printer's MAC address. This will prevent situations where, after a router reboot, the printer receives a new address and the phone app loses connection.
