To connect your Epson L355 to a new router, use the WPS method by pressing the Wi-Fi button on the printer and then the WPS button on your router within two minutes. Alternatively, configure the wireless settings via the printer’s LCD menu or install the official Epson software on your computer to establish a secure network connection for seamless printing.
Preparation and Prerequisites
Before attempting to link your Epson L355 All-in-One InkTank Printer to a new wireless network, it is essential to ensure that both devices are ready for communication. The L355 supports 2.4 GHz Wi-Fi networks using IEEE 802.11b/g/n standards. It does not support 5 GHz bands directly, so verify that your new router is broadcasting a 2.4 GHz signal. Most modern routers broadcast both 2.4 GHz and 5 GHz signals under a single SSID, but the printer may struggle to associate if the bands are combined. If possible, temporarily separate the bands in your router settings to ensure the printer can detect the correct network. Ensure that your new router is fully operational and has an active internet connection. You should have the network name (SSID) and password readily available. If you are migrating from an old router, note that the L355 does not automatically transfer settings to a new device. You must reconfigure the printer manually. For users experiencing persistent connectivity issues after changing routers, refer to our guide on Troubleshooting WiFi Connection problems which covers common interference and hardware faults.Method 1: Using WPS (Wi-Fi Protected Setup)
The WPS method is the fastest way to connect the Epson L355 without needing to type in the Wi-Fi password on the small LCD screen. This method relies on physical buttons on both the printer and the router. First, locate the Wi-Fi button on the front panel of your Epson L355. Press this button once. The Wi-Fi lamp will begin to blink, indicating that the printer is searching for a WPS-enabled router. You typically have two minutes to complete the next step. Next, go to your new router and press the WPS button. This button is often labeled "WPS" or represented by two arrows forming a circle. Press and hold it for three seconds until the WPS indicator light starts blinking. The printer and router will now negotiate the security key automatically. Once connected, the Wi-Fi lamp on the printer will stop blinking and remain solid. If the WPS option is unavailable on your router, you can check our article on Connecting a Router to Another via WiFi for alternative networking configurations that might help stabilize your setup.Method 2: Configuring via the Printer Menu
If your router does not support WPS, or if you prefer manual configuration, you can enter the network credentials directly through the printer’s interface. This method requires patience due to the small keyboard on the L355. Start by pressing the Home button on the printer’s control panel. Navigate to the Setup menu using the arrow keys. Select Network Setup, then choose Wireless LAN Setup. The printer will scan for available networks. Use the arrow keys to highlight your new router’s SSID from the list and press OK. When prompted for the password, use the keypad to enter your Wi-Fi password character by character. Pay close attention to case sensitivity. After entering the password, select Connect. The printer will attempt to join the network. If successful, the Wi-Fi lamp will turn solid. If it fails, the error code will appear on the screen, allowing you to retry with corrected credentials.Installing Software and Drivers
Physical connection to the network is only half the process. To print wirelessly from your computer or mobile device, you must install the appropriate drivers and utility software. Visit the official Epson support website and search for the L355 model. Download the full driver package for your operating system, whether it is Windows or macOS. Run the installer and select the option for wireless connection when prompted. The software will search for the printer on your local network. If the printer is not found, ensure that your computer and the printer are on the same subnet. During installation, the software may ask you to confirm the printer’s IP address. Note this IP address as you will need it for advanced troubleshooting or if you wish to assign a static IP in your router settings. For additional context on network compatibility, especially if you are using hybrid modem-router setups, see our analysis on Is the Nighthawk Modem/Router Compatible with Google Nest Router?.Troubleshooting Common Issues
If the printer connects but cannot print, the issue often lies in firewall settings or IP conflicts. Ensure that your computer’s firewall allows local network discovery. On Windows, this involves enabling "Network Discovery" in the Control Panel. On macOS, check System Preferences under Network Sharing. Another common issue is the printer losing its connection after a power outage. If this happens, repeat the WPS or menu setup steps. Avoid using USB cables for wireless printing, as this can confuse the driver if both connections are active simultaneously. Disconnect the USB cable if you intend to use Wi-Fi exclusively.Frequently Asked Questions
Why won't my Epson L355 find my new router's Wi-Fi?
The L355 only supports 2.4 GHz networks. If your router broadcasts only 5 GHz, the printer will not see it. Ensure your router’s 2.4 GHz band is enabled and visible. Additionally, hidden SSIDs (networks that do not broadcast their name) are not supported by this printer model.
Can I connect the printer using a USB cable instead of Wi-Fi?
Yes, you can connect the L355 via USB for initial driver installation or direct printing. However, this restricts printing to only the computer physically connected to the printer. For multi-user wireless printing, you must configure the Wi-Fi settings as described above.
How do I change the printer back to a different router later?
To switch routers, you must reset the network settings on the printer. Go to the Setup menu, select Network Setup, and choose Reset Network Settings. This clears the old SSID and password, allowing you to run the WPS or manual setup process again for the new location.
What should I do if the Wi-Fi lamp blinks red?
A blinking red Wi-Fi lamp indicates a connection failure. This usually means the password was entered incorrectly or the router is too far away. Move the printer closer to the router and try the setup process again, ensuring the password matches exactly, including capital letters.
Does the L355 support WPA3 encryption?
No, the Epson L355 does not support WPA3 encryption. It supports WPA2-PSK (AES) and WEP. If your new router is set to WPA3-only mode, the printer will fail to connect. You must enable WPA2/WPA3 mixed mode or WPA2-only mode on your router for compatibility.
