Changing your internet provider or installing a new router always entails a chain reaction of reconfiguring all the smart devices in the home. Epson L355, like most MFPs of this generation, does not have its own screen for selecting networks, which makes the procedure of reconnecting it to a new one Wi-Fi The router's functionality is not immediately obvious to many users. The printer still stores information about the old wireless network in its memory, ignoring the computer's attempts to locate it within the new infrastructure.
There's no need to panic in this situation, as the device's hardware is fully functional. The problem lies solely in a software mismatch between the addresses and encryption keys. You'll need to perform a full reset of the printer's network settings and restart the pairing process using either the physical WPS button on the router or specialized software.
In this article, we'll detail all the available methods for solving this problem, from the simplest to those requiring a cable connection. Understanding how Epson network modules work will help you avoid errors and quickly get your office equipment back up and running. The key is the sequence of actions: first reset, then search, and only then enter the password.
⚠️ Please note: The interfaces of Epson software utilities may differ slightly depending on the version of the Windows or macOS operating system, as well as the version of the installed driver.
Why doesn't the printer see the new network?
Many users mistakenly believe that the MFP should automatically switch to a new network if it has the same name (SSID) as the previous one. This is a misconception, as the printer's network module identifies the access point not only by name, but also by a unique identifier. MAC address router. Even if the name and password match, hardware differences in the equipment block automatic connection.
Furthermore, the device's memory may contain conflicting IP addresses or static DNS settings that were relevant for the old gateway. The new router assigns addresses from a different range, and the printer's attempt to connect to the old data results in a connection timeout. This is why the first step should always be clearing the printer's network settings.
It is also worth considering the frequency ranges. Model L355 supports the 802.11 b/g/n standard, which means it operates exclusively within the range 2.4 GHzIf your new router is configured to operate only in the 5 GHz band or has separate names for different frequencies, the printer will not physically see the network in the list of available networks. Make sure 2.4 GHz mode is enabled on the router.
Resetting the Epson L355 printer's network settings
Before attempting to connect the devices, you must reset the printer's network module to its factory default state. This will delete all saved Wi-Fi profiles, including information about your previous router. This procedure is performed exclusively using the mechanical buttons on the control panel, as the on-screen menu is unavailable at this point.
Press and hold the Wi-Fi button until the power and network lights begin flashing alternately. This process takes about 5-7 seconds. Once the lights begin flashing, release the button. The printer is now in configuration standby mode and ready to search for a new access point.
Make sure the Wi-Fi indicator on the front panel starts blinking green. This indicates the module is active but the connection has not been established. If the indicator lights are off or remain on continuously, repeat the reset procedure, paying attention to the length of the press.
☑️ Pre-reset check
Connection method via WPS button
The fastest way to make friends Epson L355 With a new router, use WPS (Wi-Fi Protected Setup). This method automatically transmits the network password without having to enter it manually, which is especially convenient if you have a complex encryption key. To do this, your new router must have a physical WPS button or a corresponding function in the web interface.
Press and hold the WPS button on the router for 2-3 seconds until the WPS indicator on the router starts blinking. Immediately after, press and hold the Wi-Fi button on the printer until the power and network indicators blink alternately. The printer will begin searching for the router, and the connection should be established within a couple of minutes.
If everything went well, the Wi-Fi indicator on the printer will turn green and stop blinking, becoming solid. This means the device has received an IP address from the new router and is ready to use. Computers or phones connected to the same network should now automatically detect the printer.
Configuration via the EpsonNet Config utility
If the WPS method doesn't work or your router doesn't support this feature, you'll have to use a more advanced tool - a utility EpsonNet ConfigTo do this, you'll need a Windows or macOS computer that's already connected to the new Wi-Fi router. The program allows you to manage the printer's network settings even without a direct connection, using a temporary direct connection.
Download and install the utility from the official Epson support website. Launch the program, and it will scan your network. Even if the printer isn't connected to Wi-Fi but is in reset mode (the indicator light is blinking), the utility can detect it as "Not Connected" or by MAC address. Select your device from the list and go to the wireless network settings.
In the window that opens, you'll need to find your new network in the list of available networks (SSID) and enter the password. The utility will automatically transfer this data to the printer. Once the settings are successfully transferred, the Wi-Fi indicator on the MFP should stop blinking and turn solid green. Your computer may temporarily lose connection with the printer during the setup process; this is normal.
⚠️ Important: Make sure that Windows firewall or antivirus software is not blocking EpsonNet Config, otherwise the program will not be able to send settings to the printer.
Using a USB cable for initial setup
In cases where wireless methods fail, the most reliable option remains using a USB cable. This method requires drivers and software. Epson Install Navigator or a complete driver package for your model. The cable allows the computer to directly introduce the printer to the new router's settings.
Connect the printer to your computer via USB and turn it on. Run the software installer. During the installation, select "Wireless Network" as the connection type. The program will detect that the printer is connected via USB and prompt you to switch to Wi-Fi.
Follow the on-screen instructions, select your new network from the list and enter the password. After the program reports successful setup, it will prompt you to disconnect the USB cable. From this point on, the printer will work wirelessly. This method is advantageous because it immediately installs up-to-date drivers compatible with the new operating system.
What should I do if my computer doesn't see my printer via USB?
Make sure the cable is secure and firmly seated. Try a different USB port, preferably on the back of the system unit (not through a USB hub). Also, check if the printer's power light is on.
Common mistakes and their solutions
Even if you strictly follow the instructions, nuances may arise depending on the specific equipment. Users often encounter a situation where the Wi-Fi indicator blinks endlessly. This indicates that the printer can see the network but is unable to authenticate. Check that the password is entered correctly: case sensitivity (upper and lowercase letters) is critical here.
Another common issue is MAC address filtering on a new router. If you have this security feature enabled, the router blocks all unknown devices. You need to find the printer's MAC address (print a status report or look on the sticker on the back) and add it to the whitelist of allowed devices in the router settings.
Below is a table to help diagnose the condition using indicators:
| Wi-Fi indicator status | Meaning | Action |
|---|---|---|
| Turned off | The network is turned off | Press the Wi-Fi button to turn it on |
| Flashing (green) | Search for network or reset | Please wait or start setup |
| On (green) | Connection established | The printer is ready to print. |
| Flashing (orange) | Connection error | Check the password or distance to the router |
Frequently Asked Questions (FAQ)
Can Epson L355 be connected to a 5GHz network?
No, the L355 model only supports 802.11 b/g/n standards, which operate in the 2.4 GHz band. If your router only broadcasts 5 GHz, the printer won't be visible to the network. You'll need to enable 2.4 GHz support in your router settings or combine the networks under a single name.
Do I need to remove the old printer from the system before setup?
This is recommended, but not required. If you simply changed your router, you can try updating the existing printer's port in the device properties. However, if the system sees it as "Offline," it's easier to remove the device and re-add it through "Devices and Printers" after setting up Wi-Fi.
The printer is connected, but the computer doesn't see it. What's wrong?
Most likely, your computer and printer are on different subnets. This often happens if "Guest Network" is enabled on your router. Make sure both devices are connected to the main network, not the guest network, as client isolation in guest mode prevents data exchange between devices.
How to find out the printer's IP address after connection?
Press and hold the "Network Info" button on the printer for about 7 seconds. The printer will print a report showing the current IP address (e.g., 192.168.1.5). This address is needed to manually install the printer in the system.
