[dmkmedia]

i have updated the wifi and the web interface but the firmware won't install here is what i have at this moment

Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.20 (2017-12-23)
WiFi Server Version: 1.21
Web Interface Version: 1.21.2-dc42

when i try to upload it i get
M997 S0
Error: M997: Firmware binary "DuetWiFiFirmware.bin" is not valid for this electronics

[dc42]

Where did you get the DuetWiFiFirmware.bin file from?

You should download Duet2CombinedFirmware.bin and upload that. If the existing firmware wants to install DuetWiFiFirmware.bin instead, rename Duet2CombinedFirmware.bin to DuetWiFiFirmware.bin.
