Coming from Firmware 1.21 with not working WiFi i did the following steps:

1. Erase all the old .bin files from the /sys folder
2. Copy new .bin files to the /sys folder
3. Extract the DuetWebControl.zip folder
4. Erase the old /www folder and create a new one
5. Put the files from the DuetWebControl folder in the /www folder
6. Put a semicolon in front of the M552 S1
7. Write a Macro via Notepad++ (edited an existing and saved with new name):
   M552 S0
   G4 S1000
   M587 S"My SSID" P"my Password"
8. Put the SD Card back into the duet and power it up
9. M997 S0 update was successful
10. M997 S1 update was successful
11. M587 and got:
    Remembered networks: MyNetwork IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0 MyNetwork IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0
12. M552 S1 and got: WiFi module is connected to access point MyNetwork, IP Adress 192.168.2.113
    35 seconds later: WiFi reported error: Lost connection, auto reconnecting
    40 seconds later: WiFi reported error: Timed out while trying to connect to MyNetwork Wifi reported error: no known networks found WiFi modul is idle
    all these messages came twice in a loop, then it stopped to reconnect.

Thanks for the reply

I followed the steps for updating from FW 1.18 or earlier. At least i thought i did. I always updatet via the SD card.
First i downloaded version 2.02 from GitHub, put the .bin files on the SD card and installed via M997 S0:1
I had some problems with this firmware, so i thought maybe the version 2 is for newer duets only, so i tried version 1.20.
Still didn't work, so i pushed the erase button.
Then i followed the tutorial "Recover from erase and basic setup" and installed FW 1.19

Since the erase butten really erases everything, what firmware do i come from now? Does the Duet still know that it once ran FW 1.18?
What FW should i try next?
Is ist better not to skip any FW and install one after another?

I have a Duet WIFI. But i was confused about the name "Duet 2 Wifi". I searched my duet Wifi for any information about its version, but all i read was Duet Wifi, so i assumed there is already an updatet version of it. So if this isnt true, and i already heav a Duet 2 Wifi, the question about the firmware compatibility is obsolete

Hello

I tried to update my Duet Wifi (Gen1). After the Update, the DWC was no more available. The Blue LED next to the WiFi Module flashes 2-3 Time (at about 1 Hz), then the LED is on for about 20 seconds permanently, then the LED starts to flash again. Somtimes this repeats for 2 or 3 loops, then the LED stays off.

What i did:
I tried different firmware versions (2.21, 1.20, 1.19) since i could not get an answer if there are firmware versions only vor Gen2 Duets or if i can pick every firmware vor every Duet. I also pushed the erase button and started from zero. I got different problems with every firmware, but the WiFi beaviour was always the same. Currently I am on firmware version 1.21, running on "Duet Wifi 1.02 or later".
I disabled any other wifi source near the printer (Mobile Phone and Laptop) and unplugged the wifi router. Makes no difference

My Printer is a custom made cartesian printer.

So my main question are:

1. Whats the best suitable firmware version for older duets?
2. What can be the reason for the wifi behaviour?

thanks for any help
