I've seen some people having issues with Wi-Fi and this printer. Wi-Fi issues don't necessarily mean it's a printer error. My wi-fi is stable and I have set the wi-fi type to DHCP so that if the wi-fi goes off for some reason the printer will obtain an IP address again. Others state that the printer goes into a deep sleep and they cannot wake it up. The Brother website states that if the printer loses its Wi-Fi connection and is unable to reconnect it will do just that. I had no problems sleeping and I repeat that my WiFi is stable and the signal strength is sufficient. For the price you can't go wrong with this printer in my opinion.
