No wifi en errors after update 1.19

Nengerman

Update via Usual procedure wifi failed.
No connection more with wifi

Fallback procedure #1
• If WiFi is not working, but you can connect to the board via USB/Pronterface:
• Take the on-board SD card out and put it in a computer,
• Copy the new DuetWiFiFirmware.bin file to the /sys folder. It must be called exactly DuetWiFiFirmware.bin on the SD card. Also make sure that file iap4e.bin is present in /sys.
• Replace the on-board SD card in the DuetWiFi
• Restart the DuetWiFi and connect with Pronterface
• Send command M997 S0 to install the firmware.
• Disconnect Pronterface, then when the USB port disappears and reappears about 20 seconds later, reconnect.

Printer is now online.

How can I solve this

Did you read and follow the instructions prefaced IMPORTANT! on the download page when you updated the firmware?

Nengerman

If you mean this page, yes

https://duet3d.com/wiki/Updating_main_firmware

Dougal1957

no not that page at all this is the one you want https://github.com/dc42/RepRapFirmware/blob/dev/WHATS_NEW.md

Read it all carefully

Can I try the Fallback procedure # 3

dc42

If you have already installed main firmware 1.19 successfully, you don't needs to use the fallback procedure. Just copy the DuetWiFiServer-1.19.bin to /sys on the SD card and rename it to DuetWiFiServer.bin. Also create a /www folder on the SD card and extract the DuetWebControl files to /www on the SD card and described at https://duet3d.com/wiki/Upgrading_to_DuetWiFiFirmware_1.19. Then pop the SD card back in the Duet, restart it, send M997 S1 to install the wifi firmware, and proceed with the instructions for configuring your access point details.

It worked. It works.
Only confusing that there are several manuals for update firmware on the internet

Thank you for the assistance.
