Brother Printer Offline Fix — Deep Sleep Mode Solution
The most common cause of Brother printer not connecting to the network is the deep sleep mode. Brother printers disconnect from Wi-Fi during deep sleep, causing them to appear offline. Press any button to wake the printer immediately. To prevent the Brother printer not connecting issue permanently: go to the printer menu, General Setup, Ecology, Sleep Mode, and increase the sleep timer or disable deep sleep. Our Brother printer support USA team can configure this remotely as part of our Brother printer troubleshooting service.
