Thank you for the video. Here’s what worked for my Epson ET-2850: The error was not letting me access the "Wi-Fi Setup" menu. I had to restart the printer. (1) Restart the printer (I left if off for 5 minutes and took the power cable off both ends). (2) As soon as you see the home screen scroll to the right and select “Wi-Fi Setup”. You can also go to Settings - Network Settings - Wi-Fi Setup. (3) Select “Wi-Fi (Recommended)”. (4) Press OK to proceed. (5) Select “Others”. (6) Select “Disable Wi-Fi” and confirm your selection. (7) Switch off the printer (for a couple of minutes) and back on. I hope this helps someone out there.
