How to Fix WiFi Not Connecting on a Brother Printer: WPS, Wireless Setup Wizard, and Manual IP Configuration Fixes

A Brother printer that refuses to connect to WiFi is one of the most common — and most fixable — home networking headaches. Whether you see a blinking WiFi light, a “Connection Failed” error on the display, or the printer simply never appears in your Windows or macOS print dialog, the root cause is almost always one of a handful of configuration issues. This guide walks through every fix in order from quickest to most thorough.

Before You Start: Check the 2.4 GHz Requirement

The single most important thing to know about Brother printers: nearly all Brother wireless printers only support the 2.4 GHz WiFi band. If your router broadcasts a combined SSID (one network name for both 2.4 GHz and 5 GHz), your phone or laptop will often connect on 5 GHz while the printer cannot. Make sure you are connecting the printer to a 2.4 GHz SSID. If your router merges both bands, either temporarily disable 5 GHz during setup or split them into two separate SSIDs in your router’s admin panel.

Also confirm that your router uses WPA2-PSK with AES encryption. Brother printers do not support WPA2-PSK with TKIP — using TKIP causes an immediate “Connection Fail” error with no further explanation. Check your router’s wireless security settings and switch to AES (sometimes labeled “WPA2-AES” or “WPA2-Personal”) before proceeding.

Method 1: Print a Network Configuration Report

Before changing anything, print a Network Configuration Report to see the printer’s current network status. On most Brother models:

1. Press Menu on the control panel.
2. Navigate to Print Reports (or Network Configuration).
3. Select Network Configuration and press OK.

Check the IP address field on the printout:

• All zeros (0.0.0.0) — the printer has not connected to the network at all.
• 169.254.x.x (APIPA) — the printer connected to the WiFi but could not get an IP address from your router’s DHCP server. Restart your router and try again.
• Valid IP (e.g., 192.168.1.x) — the printer is on the network; the issue is likely a driver or firewall problem on your computer.

The report also shows the SSID the printer last tried to join, which is useful for catching typos in the network name.

Method 2: WPS Push-Button Connection

WPS (Wi-Fi Protected Setup) is the fastest way to connect a Brother printer without typing a password. Your router must have a physical WPS button.

1. On the printer, press Menu and navigate to Network → WLAN → WPS w/ PBC (or WPS/AOSS on older models).
2. Press OK. The printer will display “Press Key On Rtr” or similar.
3. Within 2 minutes, press the WPS button on your router and hold it for 1–2 seconds until the router’s WPS indicator flashes.
4. Wait up to 2 minutes. The printer’s WiFi indicator will go solid when the connection is established.

If WPS fails: Some routers require WPS to be enabled in the admin panel first. Also, WPS operates over 802.11b/g, so make sure your router has not disabled legacy modes. If the printer still will not connect via WPS, proceed to the Wireless Setup Wizard below.

Method 3: Wireless Setup Wizard (Manual SSID Entry)

The Wireless Setup Wizard lets you manually select your network and enter the password — the most reliable method when WPS is unavailable or failing.

1. Press Menu → Network → WLAN → Setup Wizard and press OK.
2. When prompted, select Yes to enable WLAN (if asked).
3. The printer will scan for nearby networks. Use the arrow keys to scroll to your SSID and press OK.
4. If your SSID does not appear, select New SSID and type it manually. Network names are case-sensitive.
5. Enter your WiFi password. Use the keypad to cycle through characters — each key cycles through letters, numbers, and symbols. Double-check capitalization; passwords are also case-sensitive.
6. Press OK to confirm. The printer will attempt to connect and display “Connected” when successful.

If the printer shows “Connection Fail” immediately after entering credentials, revisit the WPA2-AES vs. TKIP issue described above, or verify the password by connecting a phone or laptop to the same network first.

Method 4: Manual IP Address via Brother Web Management

If your printer connects to WiFi but keeps dropping or cannot be found by your computer, assigning a static IP address prevents DHCP lease conflicts.

1. Print the Network Configuration Report to find the printer’s current IP address (e.g., 192.168.1.50).
2. Open a web browser on any device on the same network and type that IP address into the address bar.
3. The Brother Web Management page will open (no login required on most models; default credentials are “admin” / “access” if prompted).
4. Navigate to Network → Wired (or Wireless) → TCP/IP.
5. Change Boot Method from Auto to Static.
6. Enter an IP address outside your router’s DHCP range (e.g., if your router assigns 192.168.1.2–192.168.1.200, use 192.168.1.201).
7. Fill in the Subnet Mask (typically 255.255.255.0) and Gateway (your router’s IP, usually 192.168.1.1).
8. Click Submit. The printer will reboot and come back online at the new static IP.

After setting a static IP, update the port in your printer driver on Windows: go to Devices and Printers → right-click your Brother printer → Printer Properties → Ports tab → Add Port → Standard TCP/IP Port and enter the new static IP.

Method 5: Reset the Network Settings and Start Over

If none of the above methods work, a complete network reset clears any corrupted configuration and lets you start fresh.

1. Press Menu → Network → Network Reset (or Initial Setup → Reset → Network on some models).
2. Confirm the reset. The printer will reboot.
3. After reboot, run the Wireless Setup Wizard again (Method 3).

After a network reset, you may also need to reinstall the printer driver on your computer. Download the latest full driver package from support.brother.com, selecting your exact model number. The full package includes the Network Connection Repair Tool, which automatically detects and fixes IP address mismatches between the printer and your PC.

Common Error Messages and What They Mean

• “Connection Fail” — wrong password, TKIP encryption, or printer is out of 2.4 GHz range.
• “Authentication Error” — security mismatch; verify the router uses WPA2-AES and that the password is correct.
• “IP Address taken” or printer keeps going offline — DHCP conflict; assign a static IP (Method 4).
• WiFi light flashing but never going solid — printer is in setup mode but cannot find or join the network; run the Setup Wizard again and double-check the 2.4 GHz band requirement.

Quick Checklist

1. Confirm your router broadcasts a 2.4 GHz SSID and the printer is within range.
2. Verify router security is set to WPA2-AES, not TKIP.
3. Try WPS push-button first — it’s the fastest method.
4. Use the Wireless Setup Wizard to manually enter SSID and password.
5. Print a Network Configuration Report to check the IP address status.
6. Assign a static IP if the printer keeps dropping off the network.
7. Reset network settings and reinstall the driver if all else fails.

Most Brother WiFi problems come down to band compatibility, encryption mismatches, or a simple typo in the password. Once you rule those out, the WPS or Setup Wizard method will get you connected in under five minutes. If you’re still having trouble after all the steps above, check your router’s DHCP client list to confirm whether the printer is appearing at all — it’s a quick way to tell whether the issue is on the printer side or the driver side.
