And for those looking to optimize the device's performance, we've added tips on choosing a Wi-Fi channel and configuring your router for stable printing.

1. Preparing for setup: what to check before connecting

Before you start setting up Samsung SL-M2020W, make sure no external factors will interfere with the process. Most often, problems arise due to incompatibility of Wi-Fi standards or incorrect router settings.

First, check supported standards: The printer only works with networks 802.11b/g/n on frequency 2.4 GHzIf your router is configured to only 5 GHz or uses 802.11ac/ax, the printer simply won't see the network. Also, make sure that:

• 🔌 The printer is plugged into a power outlet and the power indicator is green (if it is blinking orange, the device is in error mode).
• 📶 The router is within a radius of 3-5 meters from the printer (walls and partitions can weaken the signal).
• 🔒 The MAC address filter is disabled on the router (if it is enabled, add the printer's MAC address to the list of allowed addresses).
• 🔄 There are no active print tasks on the printer (if the indicator Data blinking - wait for completion or cancel the task).

Pay special attention router security settings. Samsung SL-M2020W does not support modern protocols like WPA3 - only WPA2-PSK (AES). If you have it enabled WPA3 or mixed mode WPA2/WPA3, the printer won't be able to connect. Also, avoid outdated protocols. WEP or WPA-TKIP - they are unsafe and can cause errors.

⚠️ Attention: If your router uses 160 MHz channel width (often found in newer models), the printer will not be able to connect. Switch to 20 MHz or 40 MHz in the wireless network settings.

2. Connection methods: WPS vs. manual setup

U Samsung SL-M2020W There are two main ways to connect to Wi-Fi: via WPS (the fastest) and manual input of parameters (if WPS is disabled or not supported by the router). Let's consider both options.

2.1. Connecting via WPS (recommended method)

WPS (Wi-Fi Protected Setup) allows you to connect your printer to the network without entering a password—just press a button on the router. This method works if:

• 🔄 The router has a physical WPS button or a web-based activation function.
• 🔒 Protocol enabled WPA2-PSK (WPS does not work with WPA3).
• ⏱️ The router supports the mode PBC (Push Button Configuration).

Instructions:

1. Make sure the printer is turned on and located near the router.
2. Press and hold the button Wi-Fi on the printer (about 3 seconds) until the indicator starts flashing blue.
3. Press the button within 2 minutes WPS on the router (usually it is signed or marked with the 🔄 icon).
4. Wait for the indicator Wi-Fi If the printer light turns green, this means the connection is successful.

If the indicator continues to flash or remains orange, repeat the process. Sometimes rebooting the router before trying again helps.

2.2. Manual connection via the printer panel

If WPS isn't available, you'll have to enter your network settings manually. To do this:

1. Press and hold the button Wi-Fi on the printer until the indicator starts flashing blue.
2. Release the button and press it again once - the printer will start searching for networks.
3. Wait until the indicator flashes green (network found), then press the button Wi-Fi again to confirm your choice.
4. Now you need to enter your password. To do this:
• Click the button Wi-Fi as many times as there are letters/numbers in the password (for example, for a password 12345678 — 8 clicks).
• Use the button Cancel (Cancel) to switch between cases (upper/lower case letters, numbers, symbols).
• After entering each character, press Wi-Fi for confirmation.

This is the most labor-intensive method, as the printer has no screen—you have to enter the password blindly. Even a single character error will reset the process.

Make sure the router is broadcasting the SSID (the network name is not hidden)

Write down your Wi-Fi password on paper (to avoid mistakes when entering it)

Disable the guest network (the printer does not support connecting to it)

Check that DHCP is enabled on the router (the printer should automatically receive an IP address)
