My Brother printer is connected to my Wi-Fi network, but it won't print wirelessly. What steps can I take to fix this?

First, ensure your computer is connected to the same Wi-Fi network as the printer. Restart both your printer and your computer. Check the printer's IP address and make sure it hasn't changed. You might need to re-add the printer to your computer's list of devices. Also, verify your router's firewall isn't blocking the printer's communication.
