Epson EcoTank L3150 Wi-Fi Setup

The Epson EcoTank L3150 has a model-specific wireless setup path. Use the printer’s own controls and the current Epson setup software rather than repeatedly resetting unrelated settings.

Set up Wi-Fi

1. Use the L3150 Wi-Fi/WPS setup path documented in the User's Guide; if using WPS, place the router and printer into WPS setup as directed.
2. Print a Network Status Sheet after setup to verify the connection.
3. If changing from USB to Wi-Fi or connecting to a new router, use the dedicated connection-change procedure instead of reinstalling everything blindly.
4. If Wi-Fi remains unavailable, disable/re-enable Wi-Fi only through the documented product controls and retest.

If the printer is not discovered

1. Confirm the router is on and the phone/computer is connected to the intended network.
2. Temporarily avoid guest networks or VPNs that can block local-device discovery.
3. Check the printer’s network/WLAN status or connection report where this model provides one.
4. If the printer is already connected but one computer cannot find it, repair/re-add the printer on that computer instead of resetting the printer network first.

After changing router or password

Run this model’s wireless setup again with the new SSID/password. A driver reinstall alone cannot reconnect a printer whose saved router credentials are no longer valid.

Before calling it a driver problem

Prove the network layer first. If the printer itself is not connected to the router, fix Wi-Fi. If it is connected and another device can print, focus on the affected computer’s queue/software.
