Fixed - ST 2000 Wi Fi Error 202620 Ready - 1.5.23 

thanks. this is helping me. in my case I only need to access wifi card and shake it, no need to open whole printer. maybe its just a bit loose

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.

You mean to tell me that I’ll need a new WiFi board? If my printer is showing this message. I’ll never buy a epson printer ever again.

Where can I find the type number of the WiFi card I need?

Part number?
