How to connect the Epson L355 printer to Wi-Fi: 3 proven methods + troubleshooting

Multifunctional device Epson EcoTank L355 — one of the most popular solutions for home and office use thanks to its continuous ink supply system (CISS) and wireless printing support. However, many users encounter difficulties when first connecting the printer to a Wi-Fi network. Unlike a wired connection, where simply plugging in a cable is enough, setting up a wireless connection requires several steps—and the slightest mistake can lead to failure.

In this article we will look at three official connection methods (via the printer control panel, utility Epson Software Updater and technology WPS), and we will also look at typical mistakes such as Error 0x97 or the printer not being listed as available. We'll also cover the nuances of working with dual-band routers (2.4 GHz vs. 5 GHz) and provide recommendations for optimizing Wi-Fi printing speeds.

If you have already tried to connect L355 If you're trying to connect to the network but still can't get it working, check the "Common Problems" section at the end of the article. It contains solutions for 90% of cases, including resetting the printer's network settings and updating the firmware.

1. Preparing for connection: what you need to check before starting setup

Before you begin connecting, make sure you have completed the following: mandatory conditions:

• 📶 The router is turned on and distributes the Wi-Fi network (the wireless network indicator is on or flashing).
• 🖨️ Epson L355 connected to the power supply and is in standby mode (no errors are displayed on the panel).
• 📱 You have a device (smartphone, laptop, or PC) with access to the same Wi-Fi network to which the printer will connect.
• 🔒 The password for the Wi-Fi network is known (if the network is secured).

Please pay special attention to router frequency range. Printer Epson L355 supports networks only 2.4 GHzIf your router is in the mode 5 GHz or uses a combined network name (eg MyWiFi_2G_5G), the printer will not be able to detect the network. In this case:

⚠️ Attention: On most modern routers (for example, TP-Link Archer C6 or Keenetic Ultra) 2.4 GHz and 5 GHz networks are separated by default. If you have the same name for both bands, go to your router settings and temporarily disable 5 GHz or create a separate network for 2.4 GHz.

Also check if the router is in the "Security Mode" mode. 802.11n Only or AX (Wi-Fi 6)For compatibility with L355 It is recommended to use mixed mode 802.11b/g/n.

2. Method 1: Connecting via the printer control panel (without a PC)

This is the most versatile method, which works even without a computer. All you need is the printer itself and access to a Wi-Fi network.

Steps to connect:

1. Turn on the printer and wait until it boots up (the power indicator will stop flashing).
2. On the control panel, press the button Settings (gear icon).
3. Go to the section Wi-Fi → Wi-Fi Setup.
4. Select Manual setup (not to be confused with WPS!).
5. The printer will begin searching for available networks. Find your network name (SSID) and select it.
6. Enter your Wi-Fi password using the on-screen keyboard (case sensitive!).
7. Confirm the connection. If successful, a check mark and the printer's IP address will appear on the screen.

If the printer does not find your network:

• 🔄 Restart your router and printer.
• 📡 Make sure the printer is within range of the network (no further than 5-7 meters from the router).
• 🔒 Check if your network is hidden (this option should be disabled in your router settings) Hide SSID).

Plug the printer into a power outlet | Check the Wi-Fi indicator on the router | Make sure the network is operating in the 2.4 GHz band | Disable the VPN on the device you are setting up | Write down the Wi-Fi password on a piece of paper -->

3. Method 2: Connecting via the Epson Software Updater utility (from a PC)

If you have a Windows/macOS computer or laptop, you can use Epson's official utility. This method is convenient because it automatically detects the printer and suggests available networks.

Instructions:

1. Download and install Epson Software Updater With Epson's official website (select model L355).
2. Connect the printer to the computer via USB (temporarily).
3. Run the utility and select Setting up a wireless network.
4. The program will prompt you to select a network from the list. Specify yours SSID and enter the password.
5. Once connected successfully, disconnect the USB cable. The printer should remain connected to the Wi-Fi network.

Important: If the printer loses its Wi-Fi connection after disconnecting the USB port, this means the settings have not been saved. Repeat the procedure or try Method 1 (via the control panel).

4. Method 3: Quick connection via WPS (if your router supports it)

Technology WPS (Wi-Fi Protected Setup) allows you to connect your device to a network without entering a password. This method only works if:

• 🔄 On the router WPS is enabled (usually a button with a symbol of two arrows or the inscription WPS).
• 🔒 The network is password protected (WPS does not work with open networks).
• ⏱️ The router supports the standard WPA2-PSK (most modern models support it).

How to connect Epson L355 via WPS:

1. On the printer, go to Settings → Wi-Fi → WPS.
2. Select Start searching.
3. For 2 minutes press the button WPS on the router (usually you need to hold it for 3-5 seconds).
4. Wait for the successful connection message to appear on the printer screen.

⚠️ Attention: Some providers (eg Rostelecom or Beeline) disable WPS by default for security reasons. If the button doesn't work, check your router settings in the Wi-Fi → WPS.

5. Checking the connection and setting up Wi-Fi printing

After a successful connection, you need to make sure the printer is working correctly on the network. To do this:

1. On your computer or smartphone, open the list of available printers:
   • 🖥️ Windows: Start → Settings → Devices → Printers & Scanners.
   • 📱 Android: Go to the print settings in any application (for example, Google Docs).
   • 🍎 macOS/iOS: The printer should appear in the section Seal automatically.

If your printer is not displayed, add it manually by entering the IP address (can be found on the printer screen under Net).

Print a test page to check your connection speed and quality.

If printing is slow or stops:

• 📶 Check the Wi-Fi signal strength on your printer (there should be a signal strength indicator in the network settings).
• 🔄 Move the printer closer to the router or use Wi-Fi repeater.
• 🔧 In your router settings, change the Wi-Fi channel to a less busy one (for example, with 6 on 11).

6. Common mistakes and their solutions

Even with proper setup, glitches can still occur. Here are the most common issues and how to fix them:

If none of the methods helped, do the following: full printer reset:

1. Turn off the printer.
2. Press and hold the button Stop/Reset (red) and hold for 10 seconds.
3. Turn on the printer without releasing the button for another 5 seconds.
4. After rebooting, please repeat the Wi-Fi setup.

  2. Find the section in your router settings DHCP → Address Reservation.
  3. Add the printer's MAC address and assign it a fixed IP (e.g. 192.168.1.100).
• 🛡️ Disable power saving for USB ports (if the printer was connected via USB previously). In Windows, this is done in Device Manager → USB Controllers → Properties → Power Management.

If you have a dual-band router, you can Force the printer to bind to 2.4 GHz, even if the networks are combined. To do this:

1. Go to your router settings.
2. Find the section Wi-Fi → Radio Module Settings.
