If your Brother printer goes offline after changing Wi-Fi network settings, it may still be connected to the old network. Check the printer’s Wi-Fi settings and connect it to your new network. Restart both the printer and router, then verify the printer’s IP address. Updating the Brother printer driver and removing/re-adding the printer can also restore communication.
