How to connect the Samsung SCX-3405W to a Wi-Fi router

Modern office equipment is increasingly moving away from bulky wires and toward wireless communication technologies. Samsung SCX-3405W MFP is no exception and supports the IEEE 802.11b/g/n standard, allowing you to place the device anywhere in the room where there is a strong signal. Connection Samsung printer Connecting to a home or office network opens access to printing from mobile devices and allows you to use a scanner over the network, significantly increasing your work efficiency.

Before you begin, make sure you know your Wi-Fi network password and that it meets security requirements. This is typically a combination of letters and numbers, and is case-sensitive. If you plan to use WPS, make sure your router supports it and has it enabled.

Equipment preparation and compatibility testing

The first step is physical preparation Samsung SCX-3405W Ready for operation. The device must be plugged into a power outlet, and the toner cartridge must be installed in the appropriate compartment. It is important that the MFP be located within a strong signal range, ideally no more than 10-15 meters from the router, with no thick concrete floors between them.

Check if yours supports it wireless router WPA/WPA2 security standards. Older encryption protocols may not be supported by the printer's network adapter, which will result in a connection error. Also, make sure that MAC address filtering is not enabled on your router, which could block new devices.

⚠️ Important: Make sure you're connecting to a 2.4 GHz network. The SCX-3405W model doesn't support 5 GHz, so even if your router broadcasts 5G, the printer simply won't see it when scanning.

For successful setup, you will need a computer or laptop running Windows or macOS. This computer must have administrator rights to install drivers and network utilitiesDownload the full software package from the manufacturer's official website in advance to avoid compatibility issues.

Quick setup method via WPS button

The fastest way to connect Samsung printer With a router, use WPS (Wi-Fi Protected Setup). This method allows you to transfer network settings automatically, without having to manually enter a complex password on the device's control panel. First, locate the WPS button on your router; it may be physical or virtual in the router's interface.

On the control panel SCX-3405W You need to press and hold the wireless button (usually marked with an antenna icon) for a few seconds until the Wi-Fi indicator starts blinking.

The program scans available networks and prompts you to select yours from the list. After selecting the SSID, you'll be prompted to enter the password. Configuration utility The printer will automatically transfer this data to the printer, after which it will prompt you to disconnect the USB cable. The device will overwrite the network settings and attempt to connect to the router automatically.

☑️ USB Setup Checklist

Completed: 0 / 5

After disconnecting the cable, the Wi-Fi indicator on the panel printer The indicator should light up. If this happens, the device has successfully received an IP address from the router's DHCP server and is ready to use. At this point, the computer should also see the new network printer in the list of available devices.

Using the Samsung Mobile Print app

For smartphone and tablet users, the app is a great solution. Samsung Mobile Print (or its modern equivalents, such as the Samsung Print Service Plugin). This allows you to print documents and photos directly from Android or iOS mobile devices without the need for a computer.

Error indicator The printer's control panel (a flashing red light) will indicate that the process was unsuccessful. In this case, it's worth checking the network security type in your router settings.

Another common cause is a hidden SSID. If your network name is hidden, the printer won't be able to find it when scanning. Temporarily enable SSID Broadcast, configure the settings, and then hide it again if necessary, although this is rarely a problem for home printers.

You should also check the firewall or antivirus settings on the computer being used for setup. They may be blocking network packets from the setup utility to the printer. Try temporarily disabling the protection while you perform the configuration procedure.

The table below will help you decipher the status of the Wi-Fi indicator on the panel. Samsung SCX-3405W:

Indicator status Meaning Action
It doesn't burn. The wireless network is turned off Press the Wi-Fi button to turn it on
Flashing slowly Search network or setup mode Wait for completion or start setup
It's on constantly Successful connection to the network You can start printing.
Flashing quickly Data transfer Normal operation, printing is in progress
Flashing red/green Connection error Check your password and security settings

Setting up a static IP and printing a test page

After a successful connection, it is recommended to assign a static IP address to the printer in the router settings. This will prevent a situation where the printer is disconnected after a router reboot. IP address The printer's address will change, and the computer will no longer see it. You can reserve the address using the device's MAC address in the router interface.

To ensure everything is working correctly, you need to run a test page. This can be done through the printer menu itself or from your computer. On your computer, go to "Devices and Printers," right-click Samsung SCX-3405W and select Printer Properties → Test Print.

⚠️ Note: Router interfaces and driver versions may vary. If you can't find the IP reservation option, please refer to your router's manual, as the menu location varies by model and firmware.

Please note that after the reset, you will need to reinstall the drivers or use the setup utility to transfer the new network information. Also, remember to remove the old printer from the operating system's device list to avoid conflicts.

What should I do if my computer doesn't see the printer on the network after setup?

Check that your computer and printer are connected to the same network (same SSID). Make sure your computer's network settings are set to "Private Network" and not "Public," as device discovery is often blocked in the public profile. Also, try temporarily disabling Windows Firewall.

Can the SCX-3405W be connected to a guest Wi-Fi network?

Technically, this is possible if the guest network doesn't require web page authentication (Captive Portal). However, printers often fail to function properly in isolated guest networks where communication between devices is blocked. It's better to use the primary network.

How do I find the printer's MAC address to configure my router?

Press the Wi-Fi button on the printer panel once (without holding it down). The device will print a network configuration report. This report will include the MAC address (Wireless MAC Address), which is needed to bind to the router.

Does the model support WPS Push Button and PIN code?

The SCX-3405W model primarily supports the Push Button (PBC) method, which requires pressing a button on both the router and printer. Entering a PIN via the printer's control panel may not be possible due to the lack of a full-fledged display, so use the push button method instead.
