Why Does My Brother Printer Keep Disconnecting From WiFi?

Several factors can cause intermittent wireless connections.

Some of the most common causes include:

• Weak WiFi signal
• Router restarting automatically
• Outdated printer firmware
• Incorrect wireless settings
• IP address conflicts
• Power-saving features
• Outdated printer drivers
• Network interference
• Dual-band WiFi compatibility issues
• Temporary software glitches

Identifying the root cause makes troubleshooting much easier.

Check Your WiFi Signal Strength

A weak wireless signal is one of the leading reasons Brother printers disconnect.

Move the printer closer to your router if possible.

Avoid placing the printer near:

• Microwaves
• Cordless phones
• Thick concrete walls
• Metal cabinets
• Bluetooth devices

For the most reliable performance, the printer should receive at least a medium to strong WiFi signal.

Restart Your Printer and Router

Temporary network issues are often resolved with a simple restart.

Follow these steps:

1. Turn off the Brother printer.
2. Unplug your WiFi router.
3. Wait 60 seconds.
4. Plug the router back in.
5. Wait until the internet connection is restored.
6. Turn the printer back on.
7. Reconnect the printer to your wireless network.

This refreshes the network connection and clears temporary communication errors.

Verify the Wireless Network Settings

Sometimes the printer connects to the wrong network.

Check that:

• The printer is connected to your current WiFi network.
• The WiFi password is correct.
• The network name (SSID) hasn’t changed.
• Guest networks are not being used unless intended.

If your router was recently replaced, reconnect the printer using the new network credentials.

Update Brother printer firmware.

Outdated firmware may cause wireless instability.

Firmware updates often include:

• Connectivity improvements
• Security enhancements
• Bug fixes
• Better router compatibility

Updating your printer firmware can improve wireless performance and reduce unexpected disconnects.

Install the Latest Brother Printer Driver

Old or corrupted printer drivers may interfere with communication.

Update your driver if:

• Printing randomly stops
• The printer frequently appears offline
• Windows cannot detect the printer
• Connection errors occur after operating system updates

Reinstalling the driver can often resolve persistent wireless issues.

Assign a Static IP Address

Many routers automatically assign new IP addresses.

When the IP address changes, your computer may lose communication with the printer.

Assigning a static IP address helps maintain a stable connection.

Benefits include:

• Faster printer discovery
• Fewer offline errors
• Improved reliability
• Reduced connection interruptions

This is especially useful in offices with multiple devices.

Disable Power-Saving Features

Some Brother printer models enter sleep mode too aggressively.

Check your printer settings and the following:

• Increase sleep timeout
• Disable deep sleep if available
• Prevent your computer from turning off network adapters

These adjustments help maintain an active wireless connection.

Check Your Router Settings

Certain router configurations can interrupt printer communication.

Review settings such as the following:

• DHCP lease duration
• MAC address filtering
• Wireless isolation
• Firewall restrictions
• WPA security mode

Most Brother printers work best with WPA2 security.

If your router recently received a firmware update, verify that wireless settings remain compatible with your printer.

Reduce Wireless Interference

Wireless interference can cause frequent disconnects.

Try these solutions:

• Change the WiFi channel.
• Use the 2.4 GHz network if your printer doesn’t support 5 GHz.
• Move nearby electronic devices.
• Place the router in an open location.
• Avoid crowded wireless channels.

Improving signal quality often resolves intermittent connection issues.

Reset the Network Settings on Your Brother Printer

If none of the previous methods work, reset the printer’s network configuration.

General steps include:

1. Open the printer menu.
2. Navigate to Network Settings.
3. Select Network Reset.
4. Restart the printer.
5. Reconnect to WiFi.

This removes incorrect wireless settings that may be causing repeated disconnects.

Prevent Your Brother Printer From Disconnecting Again

Follow these best practices to maintain a reliable wireless connection:

• Keep printer firmware updated.
• Install the latest printer driver.
• Use a strong WiFi signal.
• Assign a static IP address.
• Restart your router periodically.
• Avoid network interference.
• Keep the printer within router range.
• Use high-quality networking equipment.
• Secure your wireless network with WPA2 or WPA3.

Routine maintenance can prevent many future connectivity problems.

Quick Answers

Why does my Brother printer keep disconnecting from WiFi?

Common causes include weak wireless signals, outdated firmware, router issues, IP address conflicts, power-saving settings, or outdated printer drivers.

Will restarting the router fix the issue?

Yes. Restarting both the printer and router often resolves temporary network communication problems.

Can outdated firmware cause WiFi disconnects?

Yes. Firmware updates frequently include fixes that improve wireless stability and compatibility with newer routers.

Frequently Asked Questions

Why does my Brother printer keep going offline?

The printer may lose communication because of a weak WiFi signal, router issues, changing IP addresses, or outdated drivers.

Should I use 2.4 GHz or 5 GHz WiFi?

Most Brother wireless printers work more reliably on a 2.4 GHz network. Check your printer’s specifications to confirm compatibility.

Can antivirus software block my printer?

Yes. Some firewall or security software may prevent communication between your computer and printer. Temporarily disabling the firewall can help identify the issue.

Is a static IP address recommended?

Yes. A static IP address prevents the printer from receiving a different IP after a router restart, reducing offline and disconnect issues.

When should I contact Brother support?

If your printer continues disconnecting after updating firmware, reinstalling drivers, resetting network settings, and testing another WiFi network, the issue may require professional assistance.
