If your Brother printer keeps disconnecting from WiFi, you're not alone. This is a common issue faced by many users, especially when using wireless printing in home or office setups. Frequent drops in WiFi connectivity can disrupt printing jobs and affect your workflow. In this article, we’ll explain the most common causes and walk you through step-by-step solutions to keep your Brother printer connected to WiFi consistently.

🔍 Why Does My Brother Printer Keep Losing WiFi Connection?

Before jumping into solutions, it helps to understand what might be causing the issue:

  • Weak or unstable WiFi signal

  • Printer placed too far from the router

  • IP address conflicts

  • Power-saving mode on the printer

  • Firmware or driver issues

  • Network settings reset during router reboot

✅ Fix 1: Check WiFi Signal Strength

A weak or unstable signal is one of the main reasons a printer disconnects from WiFi.

What to do:

  • Move your printer closer to the WiFi router.

  • Avoid placing the printer near walls or electronic interference (like microwaves or cordless phones).

  • Use the printer’s Network Configuration Report to check signal strength. Look for a signal quality of 70% or higher.

✅ Fix 2: Assign a Static IP Address

If your printer’s IP address changes every time your router restarts, it can break the connection.

How to set a static IP:

  1. Access your router’s admin panel (usually by typing 192.168.1.1 in your browser).

  2. Find the DHCP reservation or IP assignment section.

  3. Locate your Brother printer in the connected devices list.

  4. Assign it a static IP address to ensure it doesn’t change.

💡 Setting a static IP helps your computer consistently find the printer on the network.

✅ Fix 3: Disable Deep Sleep or Power-Saving Mode

Some Brother printers go into Deep Sleep mode, causing them to disconnect from WiFi.

How to disable it:

  1. Press the Menu button on your printer.

  2. Navigate to General Setup > Ecology > Sleep Time.

  3. Set the sleep timer to a higher number or disable it entirely.

✅ Fix 4: Update Firmware and Drivers

Outdated firmware or drivers can cause connectivity issues.

For firmware:

  • Go to the Brother Support website

  • Enter your printer model and check for the latest firmware

For drivers:

  • On your computer, uninstall the current printer driver.

  • Reinstall the latest version from Brother’s official site.

🛠 Make sure to select the correct OS version (Windows/macOS) before downloading.

✅ Fix 5: Reconnect the Printer to WiFi

Sometimes reconfiguring the wireless setup resolves disconnection issues.

Steps:

  1. On your Brother printer, go to Menu > Network > WLAN > Setup Wizard.

  2. Select your WiFi network (SSID) and enter the password.

  3. Let the printer reconnect and print a Network Report to confirm connection.

✅ Fix 6: Restart Network Devices

Temporary glitches in your network equipment can affect connectivity.

What to do:

  • Power off your printer, router, and computer.

  • Wait 30 seconds, then turn them back on in this order: Router → Computer → Printer.

  • Try printing a document again to see if the connection holds.

📝 Final Tips

  • Use a dual-band router: If possible, connect your printer to the 2.4GHz band—it has better range than 5GHz.

  • Avoid guest networks: Make sure the printer and computer are on the same WiFi network.

  • Keep your router firmware updated to ensure compatibility with devices like printers.

🤔 Still Not Working?

If your Brother printer continues to lose its WiFi connection:

  • Try a wired Ethernet connection for more stability.

  • Contact Brother Customer Support for model-specific help.

📌 Conclusion

If your Brother printer keeps losing WiFi connection, the issue can often be traced to signal strength, power settings, or IP configuration. Follow the steps above to restore a stable connection and enjoy hassle-free wireless printing. Regular maintenance and keeping your software up-to-date go a long way in avoiding these issues in the future.
