Changing a router, updating a wireless network password, or moving to a new office are common situations faced by every user of office equipment. When a router changes its settings, Epson L3150 printer The printer loses connection to the computer and stops printing, requiring immediate attention. The reset process isn't always intuitive, as this model lacks a full color display and is controlled via a combination of buttons and indicators.
In this article, we'll detail all the available methods for restoring the wireless connection for your model. You'll learn how to use the button Wi-Fi on the device body, how to use WPS technology for instant pairing, and how to completely reinstall the drivers from a computer. Understanding these mechanisms will allow you to quickly restore your MFP to working order without calling a technician.
Preparing to set up a wireless connection
Before you begin changing your network settings, you need to make sure your equipment is ready for use. Epson L3150 Only supports the 2.4 GHz band, so make sure your router is broadcasting in this standard or that compatibility is enabled. If you're using a dual-band router, it's best to temporarily separate the networks or ensure the device is connecting to the correct frequency.
You will also need to know the exact name of your network (SSID) and the current security password. Password entry errors are the most common cause of connection failures, so check your keyboard layout and letter case. Make sure the printer itself is turned on, there's paper in the tray, and it's not out of ink, as some models can block network functions if critical errors occur.
Place the device no more than a few meters away from the router during setup. Although L3150 It has a decent antenna; the signal must be as stable and strong as possible for the initial handshake and encryption key exchange. After successful setup, you can move the printer to its permanent location.
⚠️ Attention: Make sure MAC address filtering isn't enabled on your router. If it is, you'll need to first whitelist the printer's MAC address (found on the sticker on the back), otherwise the connection will be blocked.
☑️ Check before setup
Resetting the Epson L3150 printer's network settings
If the printer was previously connected to a different network, old configurations may conflict with new connection attempts. In this case, reset network settings is a mandatory first step. This action will clear the device's memory of previous SSIDs and passwords, returning the network module to its factory defaults.
To perform a reset, locate the network button (antenna icon) on the control panel. Press and hold this button for a few seconds until the indicators start flashing. Some firmware versions require a combination of buttons. Wi-Fi And Cancel (cross) at the same time.
After resetting the indicators Wi-Fi And Wi-Fi Direct The LEDs should start flashing alternately. This indicates that the device has entered connection standby mode and is ready to accept new commands. You can now proceed to selecting a pairing method.
WPS method: quick connection without entering a password
The easiest way to change the network is to use technology WPS (Wi-Fi Protected Setup)This method allows you to automatically transfer your router password to your printer, eliminating the need to manually enter complex characters on your computer or phone. The main requirement is that your router supports WPS and has a corresponding button (either physical or software-based in the web interface).
Press the WPS button on your router. The router's security light will usually start blinking after this. You have about two minutes to activate the printer's network search. Press and hold the button. Wi-Fi on the panel Epson L3150 until the indicators start flashing.
The printer and router will automatically exchange data. If everything is successful, the indicator Wi-Fi The printer's LED will turn green and stay solid. This means the device has received an IP address and is ready to work on the new network.
What to do if WPS doesn't work?
Some modern routers have WPS disabled by default for security reasons. In this case, you'll need to access the router settings via a browser (usually at 192.168.0.1 or 192.168.1.1) and enable WPS manually, or use the password entry method on your PC.
Changing Wi-Fi via a Computer (Epson iPrint and Drivers)
If automatic methods don't work, the most reliable option is to use a computer with the software installed. You will need USB cable, which is included in the kit or was purchased separately. This method allows the computer to directly broadcast Wi-Fi settings to the printer.
Connect Epson L3150 to the computer via a USB cable. Run the setup program that was installed along with the drivers. If you are changing the network on an already configured printer, find the utility in the Epson software menu. EpsonNet Config or re-install the driver by selecting the "Change connection" option.
In the setup wizard, select the "Wireless" connection type. The program will offer a list of available networks. Select your new network from the list and enter the password. The program will then send the configuration to the printer, and it will attempt to connect. The USB cable must be connected during the setup process.
Setup via smartphone and Epson iPrint app
For mobile device users, Epson has developed an application Epson iPrint, which greatly simplifies management. This method is especially convenient if you don't have a computer with a USB port nearby. The app is available for Android and iOS and allows you to configure the printer directly from your phone.
First you need to put the printer into mode Wi-Fi Direct. Click the button Network (or Wi-Fi) on the printer until the Wi-Fi Direct indicator lights up. On your phone, in the list of Wi-Fi networks, find a network with a name like DIRECT-xx-EPSON L3150 and connect to it. The default password is usually 12345678, if it has not been changed previously.
Launch the application Epson iPrintIt will automatically detect the printer. In the app menu, select "Wi-Fi Setup" or "Change Network." The app will prompt you to select a new home network from the list and enter the password. After confirmation, the phone will transmit this information to the printer.
| Indicator | State | Meaning | Action |
|---|---|---|---|
| Wi-Fi (green) | It's on fire | Connected to the network | You can print |
| Wi-Fi (green) | Flashing | Connecting | Wait for completion |
| Wi-Fi (green) | Turned off | No connection | Check settings |
| Wi-Fi Direct | It's on fire | Direct communication mode | Connect directly |
⚠️ Attention: When connecting via Wi-Fi Direct, your phone may temporarily lose internet access because it will be connected directly to the printer, not the router. This is normal behavior for this setup method.
Troubleshooting and error diagnostics
Even if all instructions are followed, technical difficulties may arise. Often the problem lies in frequency rangeThe L3150 series printers do not detect 5 GHz networks. If your router combines 2.4 and 5 GHz networks into a single network with the same name, the printer may behave unpredictably. It is recommended to explicitly separate these networks in your router settings (e.g., MyWiFi_2.4 And MyWiFi_5).
Another common reason is the wrong encryption type. Epson L3150 Works best with WPA2-PSK (AES) standards. If you have an older WEP or a specific corporate Enterprise protocol, your device may not connect. Check the security settings in your provider's account or router admin panel.
If the indicators are flashing red and green alternately, this indicates a connection error. Try rebooting the router by turning it off for a minute. It's also worth checking if your router has a limit on the number of connected devices—older router models may not assign an IP address to new devices if the limit is reached.
Frequently Asked Questions (FAQ)
Where can I find my Wi-Fi Direct password if I changed it and forgot it?
If the default password (12345678) doesn't work and you've changed it but forgotten it, the easiest way is to perform a full reset of the printer's network settings (by holding the Wi-Fi button), which will restore the default password. You can also view the password by printing a network status report: press the button. Network and the button Info (if any) or a combination of buttons to print the report, depending on the modification.
Can the Epson L3150 be connected to a hidden Wi-Fi network?
Yes, this is possible, but only via a computer using a USB cable and the EpsonNet Config software. In manual SSID entry mode, you'll need to enter the hidden network name manually, as the printer won't be able to find it in the list of available networks.
Why doesn't the printer see my router, even though other devices connect?
Most likely, your router is operating in 5 GHz-only mode or is using Wi-Fi channels that aren't supported by the printer (for example, channels 12-14 in some regions). Try forcing the channel to range 1-11 in the router settings and enabling 802.11 b/g/n mode.
Do I need to reinstall drivers after changing my Wi-Fi network?
If you change the network name (SSID) or password but the IP address remains on the same subnet, reinstalling the drivers is usually not necessary. However, if the computer has lost connection to the printer, you may need to remove the old device in Control Panel and re-add it, specifying the new IP address or finding it on the network.
