Setting up a wireless connection on a laser multifunction device of the series Brother DCP-L2520DWR This often becomes a stumbling block for users accustomed to wired interfaces. Despite the "W" in the model designation, indicating a built-in Wi-Fi module, the initial setup process requires strict adherence to the correct sequence of steps, as the device lacks a touchscreen for easy password entry.
The main difficulty is that for the initial setup, you will still need to briefly connect the printer to your computer via a USB cable or use the WPS method if your router supports this function. Wireless interface In this model it works stably, but the drivers must be installed correctly so that the operating system can detect the network address of the device.
In this article, we will examine in detail all available activation methods. wireless printing, including using a configuration utility, manual control via the device panel, and creating a permanent IP address for stable operation in corporate or home networks with complex architecture.
Equipment preparation and compatibility testing
Before you begin the software, you need to make sure the hardware is physically ready. Make sure the MFP Brother DCP-L2520DWR It's plugged in and ready, and the lights aren't flashing an error signal. You'll also need to know the exact name of your wireless network (SSID) and its password, as automatic connection without entering data is only possible using the WPS button.
An important step is to check your router's compatibility with the security protocols supported by the printer. The model supports the standards WPA2-PSK (AES) And WPA/WPA2-Personal, which is the modern standard, but older routers with WEP encryption or specific corporate network settings may cause difficulties. If you're using a guest Wi-Fi network, make sure its settings don't block communication between devices (AP Isolation).
To complete the setup process, you'll need a computer or laptop running Windows or macOS with internet access to download drivers. If you plan to connect the device from a mobile phone, install the app in advance. Brother iPrint&Scan or Brother Mobile Connect from the official app store.
⚠️ Note: If your router broadcasts both 2.4 GHz and 5 GHz networks under the same name, the printer may attempt to connect to the 5 GHz band, which it doesn't support. Temporarily separate the networks in your router settings or ensure that 2.4 GHz is prioritized.
USB Cable Setup Method (Recommended)
The most reliable way to configure network settings is to use the installation disc or a full driver package downloaded from the official website. This method is preferable, as the setup program automatically reads your current network settings and transfers them to the printer's memory, minimizing the risk of errors when manually entering characters.
Run the setup file and select the "Wireless Network" connection type. When prompted, connect. USB cable Between the computer and the MFP. At this stage, data exchange occurs: the computer transmits the router's SSID and password directly to the printer's Wi-Fi module. After successful data transfer, the program will prompt you to disconnect the USB cable, as further communication will take place over the air.
☑️ USB Setup Checklist
During the installation process, you may be asked to choose a connection method. If the program prompts you to "Configure again" or "Use current settings," choose the former for a clean configuration. This ensures that old, potentially incorrect, profiles are removed from the device's non-volatile memory.
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 (for PCs), to rule out a power shortage. Also, check Device Manager for any unknown devices.
Using WPS technology for fast connection
If your wireless router has a physical button WPS (Wi-Fi Protected Setup) or has a software activation button in the web interface, you can connect Brother DCP-L2520DWR Without entering a password or using a computer. This is the fastest method, taking less than a minute.
Press and hold the WPS button on your router for a few seconds until the wireless light starts blinking. Then, press the button on the printer's control panel. Wi-Fi Or, enter the menu and select "Network" → "WPS" → "Push Button." The device will begin searching for available WPS signals.
- 📶 Indication: If the connection is successful, the Wi-Fi indicator on the printer will be solid green.
- ⏳ Time-out: You have about 2 minutes to activate WPS on the router after starting the function on the printer.
- ❌ Error: If the indicator flashes orange or green intermittently, the connection is not established - check the range and repeat the procedure.
It's worth noting that the WPS method won't work if your router's security settings enable MAC address filtering. In this case, you'll first need to add the printer's MAC address to the router's whitelist. You can find the MAC address by printing a Network Configuration report and pressing the button. Menu → “Network” → “Print report”.
Manual setup via control panel
When a USB cable is unavailable and WPS doesn't work, manual data entry is required via the monochrome display and navigation buttons. This process requires careful attention, as menu navigation is limited to a limited number of buttons, and entering letters and numbers requires multiple keystrokes.
To get started, click the button Menu On the control panel, use the arrow keys to navigate to "Network" and press OK. Select "WLAN" and then "Setup Wizard." The printer will begin searching for available networks. Select your SSID from the list. If the network is hidden, select "Enter SSID" and enter the name manually.
When entering a password, use the arrow buttons to select a character and the button OK to confirm your selection or move to the next character. This is the most time-consuming step, especially if the password is complex and contains special characters. After entering all characters, the printer will ask for confirmation—select "Yes."
After confirmation, the printer will attempt to connect to the access point. The screen may go blank or enter power saving mode—this is normal. Wait until the Ready light comes on. If a connection is not established, the device will return to the network selection menu.
Setting up a static IP address
For stable operation in an office or smart home, where routers may frequently reboot, it is recommended to assign static IP addressThis will prevent the computer from losing the printer after rebooting the hardware, as the DHCP server will assign it a new address.
Click the button Menu, go to "Network" → "TCP/IP." Find "BOOTP Method" or "Protocol" and select "Static." Next, you'll need to enter the IP address, subnet mask, and gateway. The address must be in the same subnet as your router, but outside the range of DHCP addresses to avoid conflicts.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP Address | The printer's unique address on the network | 192.168.1.200 |
| Subnet Mask | Subnet mask (usually default) | 255.255.255.0 |
| Gateway | Your router's address | 192.168.1.1 |
| DNS Primary | Primary DNS server | 8.8.8.8 |
After entering all the parameters, you need to reboot the network module. To do this, select "Reboot" in the "Network" menu or simply turn the printer off and on. Now the device will always respond to the specified address, simplifying driver installation on other computers.
⚠️ Important: Before assigning a static IP, make sure the selected address is not already occupied by another device. You can check this by pinging the address from your computer (command
ping 192.168.x.x(in the command line).
Solving common connection problems
Even if you strictly follow the instructions, situations may arise where the printer fails to connect to Wi-Fi. One common cause is the use of characters in the password that the printer interprets incorrectly, or the use of Cyrillic characters in the network name. In such cases, it is recommended to temporarily change the router password to a simple combination of Latin letters and numbers.
Driver issues may also be the cause. If your computer can't see your printer on the network, try adding it manually by IP address. In Windows, go to "Devices and Printers" → "Add a Printer" → "The printer I want isn't listed" → "Add by TCP/IP Address."
- 🔌 Reset settings: If nothing helps, perform a full reset of network settings:
Menu→ "Network" → "Network Reset" → "Yes." The printer will reboot with factory settings. - 📡 Frequency range: Make sure you are not trying to connect your device to a 5GHz network, as it only works in the 2.4GHz range.
- 🛡️ Antivirus: Temporarily disable the firewall or antivirus software on your computer, as they may be blocking the detection of the network printer.
In some cases, updating the device's firmware can help. Check the firmware version in the network configuration report and compare it with the current version on the manufacturer's website. An update can fix TCP/IP stack errors that interfere with a stable connection.
Why doesn't my Brother DCP-L2520DWR printer see my Wi-Fi network?
The issue is most likely related to the frequency band or encryption type. This model only supports the 802.11 b/g/n standard at 2.4 GHz. If your router only operates in 5 GHz mode or uses WPA3 encryption, which the device may not support, the network will not be displayed. Try enabling mixed mode (b/g/n) in the router settings.
Can I connect this printer to Wi-Fi without a computer?
Yes, this is possible in two ways: using the WPS button on the router (if available) or manually entering the SSID and password directly from the printer's control panel using the navigation buttons and display. A computer is only needed to install the drivers, not to configure the Wi-Fi module itself.
How to find out the printer's IP address after connection?
Press the "Menu" button on the device's panel, navigate to the "Network" section, then select "TCP/IP" and press OK. The current IP address will be displayed on the screen. You can also print a network configuration report by selecting "Print Report" in the network menu.
