Modern office devices demand mobility, and wireless printing is becoming a standard rather than a luxury. Brother DCP-L2520DWR The MX200 is a reliable monochrome laser printer that supports wireless connectivity, allowing users to print documents directly from a smartphone or laptop. However, initial network setup can be challenging, as the printer lacks a full touchscreen and is controlled via a combination of buttons and an LCD display.
In this guide, we will go through all the available connection methods for the model in detail. DCP-L2520DWR to your home or office Wi-Fi network. You'll learn how to use WPS quick pairing technology, how to manually enter a password through the device's menu, and what to do if automatic network scanning fails. Proper network configuration will unlock network scanning and remote management features.
Before starting the procedure, make sure that your router is working properly and is transmitting a signal, and that the printer itself is filled with toner and ready to use. It is critically important to know the exact name of your network (SSID) and its password in advance, since the device cannot remember the input the first time if you make a mistake. It's also worth checking that the MFP is in a strong signal reception area to avoid connection interruptions while configuring drivers.
Equipment preparation and compatibility testing
Before you begin manipulating the menu, you need to make sure that the equipment is physically ready. Make sure that Brother DCP-L2520DWR Plugged into a power outlet and warmed up, and the paper tray is in place. If the device was previously connected via USB, it's best to temporarily disconnect it from the computer to prevent the system from attempting to search for the printer via a wired connection while setting up wireless mode.
An important step is checking your router's frequency range. This model supports 802.11b/g/n standards, meaning it operates primarily in the 2.4 GHz band. If your router broadcasts only on the 5 GHz band or uses a mixed mode that blocks older standards, the printer may not see the network. In such cases, it's recommended to access your router settings and ensure the 2.4 GHz network is active.
⚠️ Note: Some corporate networks use hidden SSIDs or MAC address filtering. These settings are rare in home environments, but if you don't see your network listed, check to see if the access point name is hidden in your router settings.
To successfully establish a connection, you'll also need your login information. The Wi-Fi password is case-sensitive, so have it ready in advance. If you don't know the password, you can find it on the sticker on the bottom of the router or in your provider's account if you're using default settings.
Method 1: Quick setup via WPS
The easiest and fastest way to connect Brother DCP-L2520DWR To connect to the network, use WPS (Wi-Fi Protected Setup). This method allows you to establish a secure connection without having to manually enter a complex password using the navigation buttons on the printer's small screen. For this method to work, your router must also support WPS, which is required for modern models.
The process begins by locating the WPS button on your router. It may be labeled with a corresponding text or a symbol of two arrows forming a circle. Pressing this button on the router will activate the device search mode, which will take approximately two minutes. After this, quickly navigate to the printer's control panel.
On the MFP itself, press the button Menu (Menu) on the control panel. Use the up and down arrows to find the item Network (Network) and press OK. Next, select the option WLAN and confirm your choice again. In the submenu that opens, find the item WPS and activate it. The printer will begin searching for a signal and automatically establish a connection.
- 📡 Press the WPS button on your wireless router.
- 🖨️ On the MFP panel, go to
Menu → Network → WLAN → WPS. - ✅ Wait for the "Connected" message to appear on the display screen.
- 📄 Print a network report to ensure successful connection.
Method two: Manually entering network parameters through the menu
If your router doesn't support WPS or you prefer manual setup, you can select a network from the list of available networks and enter the password manually. This method is more reliable in situations where the signal is unstable or the network name is hidden. Start by pressing the button. Menu on the device panel, then select sequentially Network, WLAN And Setup Wizard (Setup Wizard).
When the screen asks "WLAN Enable?", select "On" or "Enable" and press OKThe printer will begin searching for available wireless networks. Once the scan is complete, a list of found SSIDs will appear on the display. Use the navigation arrows to scroll through the list and find your network name. If the network is hidden, select the option to enter the name manually.
After selecting a network, the device will ask you to enter a password. The screen will switch to character entry mode. Use the arrow buttons (Up, Down, Left, Right) Navigate the virtual keyboard on the screen, selecting the desired letters and numbers. To switch between numbers, uppercase and lowercase letters, use the button Shift or a similar option on the screen. After entering the password, press OK for confirmation.
Sequence for manual input:
Menu -> Network -> WLAN -> Setup Wizard -> On -> [Select SSID] -> [Enter Password] -> OK
If the password is entered correctly, a successful connection message will appear on the screen. If you receive a "Connect Error" or "Auth Error," check that you entered the correct characters, especially if the password uses similar characters (for example, zero and the letter O).
☑️ Verify your password before entering it
Setup via USB cable using Brother software
In situations where entering data using the printer buttons seems too complicated, or the device doesn't detect the network, you can use an installation disc or a driver downloaded from the official website. This method allows the computer to transfer Wi-Fi settings directly to the printer via a temporary USB connection. Download the full driver and utility package for your model. DCP-L2520DWR from the manufacturer's website, selecting your operating system.
Run the installation file and follow the installation wizard's instructions. When prompted for a connection type, select "Wireless Network Connection." The installer will then prompt you to connect the device to the computer via a USB cable. Do not connect the cable until prompted.
When the corresponding message appears, connect the printer and PC with a USB cable. The program will automatically detect the device and prompt you to select your wireless network from the list and enter the password. After the settings are transferred to the printer, the program will prompt you to disconnect the USB cable. The MFP will then automatically connect to Wi-Fi.
| Setup stage | User action | System/Printer Response |
|---|---|---|
| Starting the installation | Select the "Wireless" connection type | USB cable connection request |
| Data transfer | Entering a Wi-Fi password in a PC window | Configuring the printer's network modules |
| Conclusion | Disconnecting the USB cable according to the instructions | Automatically switch to Wi-Fi mode |
⚠️ Note: The installer interface may vary depending on the driver version. If you're using Windows 10 or 11, the system may automatically find the driver, but for full network scanning functionality, it's best to use the full Brother software suite.
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 located on the back of the system unit. If you're using a laptop, check to see if the ports are powered down in the power saving mode.
Checking connection quality and printing a report
After successful setup, you need to verify that the printer has indeed received an IP address and is ready to use. The most reliable diagnostic method is to print a Network Configuration report. To do this, click the button Menu, go to the section Print Reports (Print reports) or Network, select WLAN Report and press OK or Start.
In the printed document, look for the "Link Status" section. If it says "Connected," then a physical connection to the router has been established. Also, check the "IP Address" field—an address like 192.168.xx confirms that the router's DHCP server has successfully assigned an address to the device. If the address begins with 169.254.xx, this indicates an IP address acquisition error, and the connection is not established.
You can also check the signal strength. The report may display it as a percentage or a graphical bar graph. If the signal strength is low (less than 30-40%), delays may occur when printing large documents or scanning. In this case, it is recommended to move the router closer to the printer or use a Wi-Fi repeater.
- 📄 Print the report via the menu
Print Reports -> WLAN Report. - 🔗 Check the "Link Status" - it should be "Connected".
- 🌐 Make sure the IP address is correct for your local network.
- 📶 Assess the signal level for stable operation.
Solving common connection problems and errors
Even if you follow the instructions carefully, difficulties may arise. One common issue is that the printer sees the network but won't connect. This is often due to the encryption type. Brother DCP-L2520DWR Supports WPA2-PSK (AES) standards, but may not work with the newer WPA3 standards or mixed WPA2/WPA3 modes. It's worth temporarily setting your router's settings to compatibility mode.
Another common cause is a MAC address filter. If the router has a whitelist of devices enabled, a new printer will be blocked even if the password is correct. Find the printer's MAC address (it's printed on the label on the back of the device or in the network report) and add it to the router's allowed list. Channel congestion may also be the problem: if there are many nearby networks, try changing the router's broadcast channel to 1, 6, or 11.
If nothing helps, reset the printer's network settings. To do this, go to the menu and select Network -> Network Reset and confirm the action (Yes). The device will reboot the network module, and you can start setting up the printer again, as if it were fresh out of the box.
Why can't my printer see my 5GHz network?
The DCP-L2520DWR model has a Wi-Fi module that operates only in the 2.4 GHz band. It is physically unable to see or connect to networks that operate exclusively in the 5 GHz band. Ensure that your router is broadcasting a 2.4 GHz network and that the network name is not hidden.
Can I connect a printer to a guest Wi-Fi network?
Technically, this is possible, but not recommended. Guest networks often have client isolation, which prevents devices within the network from seeing each other. The computer simply won't find the printer in the list of available devices, even if both are connected to the same guest access point.
How to change the printer's IP address to static?
This can be done via the web interface. Enter the printer's current IP address in your browser, log in (the default login is often "admin," the password is "access," or blank), go to Network -> TCP/IP, and select the Static method. Enter the desired IP address, mask, and gateway.
The printer prints but won't scan over the network. What's wrong?
Most likely, your computer doesn't have the full driver package, including ControlCenter4 or Brother iPrint&Scan. Simply adding the printer as a print device isn't enough for network scanning. Install the full software for your operating system from the Brother website.
