Modern inkjet MFPs Epson L355 Wireless printers allow you to print, scan, and copy documents without being connected to a computer, but to implement wireless functionality, the device must be properly integrated into the home network. Users often encounter difficulties during the initial setup process, when the printer doesn't recognize the router or the drivers aren't installed correctly. Understanding the physics of the process and the sequence of actions will help avoid most errors.
In this article, we'll cover all available connection methods in detail, from automatic setup via WPS to manual network settings. We'll pay special attention to working with mobile devices, as smartphone printing is becoming the de facto standard. Connection stability directly depends on the correctness of the entered data and the distance to the access point.
Before proceeding with the software, make sure your MFP is loaded with ink and there's paper in the tray. The device must be within range of a strong router signal. The key is that the computer and printer must be on the same subnet for successful discovery. If you're using a guest Wi-Fi network, client isolation may prevent you from connecting.
⚠️ Important: If your router simultaneously broadcasts 2.4 GHz and 5 GHz networks under the same name (Smart Connect), the printer may not detect the frequency correctly. We recommend temporarily separating the networks in your router settings or connecting the printer to the 2.4 GHz network.
Equipment preparation and compatibility testing
The first step is to physically prepare and check your router's compatibility with the security protocols used Epson L355Older encryption standards may not be supported by newer routers, and vice versa. Make sure you know your Wi-Fi network password, as you'll need it during setup.
Turn on the MFP and wait for the self-test to complete. The indicators should be solid and not flashing, which would indicate an ink supply error or a paper jam. Wireless connection will not work if the error indicator is on or the device is in sleep mode with the Wi-Fi module turned off.
- 📡 Make sure the Wi-Fi indicator on the printer panel is on or blinking, indicating that the module is ready.
- 🔌 Check that the router is turned on and transmitting a signal (you can check from your phone).
- 🔋 Make sure that the ink is filled to the upper level in the CISS tanks.
The distance between the router and printer during setup should not exceed 3-5 meters, preferably without any load-bearing walls between them. After successful configuration, the device can be moved, but it's best to perform the initial handshake in close proximity.
Automatic setup via WPS button
The fastest way to connect Epson L355 To connect to the network, use WPS (Wi-Fi Protected Setup) technology if your router supports it. This allows you to transfer security settings automatically, without manually entering a password. This method is ideal for users who don't want to mess with drivers at the start.
