Firmware 1.19 connection problems
im running duet wifi with duex2 for almost a year now without problems.
Recently i upgraded the firmware to version 1.29 and now i have a lot of connection problems.:
1. i cannot connect add all, after restarting the duet or randomly after some time i can connect.
2. it disconnects me (a lot) . " An AJAX Error has been reported etc.. Error reason : Timeout"
I dont think this is a wifi problem because it wasnt a problem with the old firmware.
im running Wifi Server version 1.19.2 and web interface version 1.19.3
Have you tried the 1.20 release?
Was there a bug in 1.19 that is fixed in 1.20 ?
i read the thread about 1.20 some are also reporting connection problems,
Maybe i try that one today.
1.20 fixed the problem
sorry it did not fixed the problem, i still get the AJAX errors.
Im running :
Duet wifi 1.) + Duex2
firmware version 1.20
wifi server version 1.20
web interface version 1.19.3
Is it possible to go back to the old firmware ? i didnt have this problem before.
This is my M122 reply.

WiFi firmware version 1.20
WiFi MAC address 5c:cf:7f:2c:25:2f
WiFi Vcc 3.32, reset reason Turned on by main processor
WiFi flash size 4194304, free heap 16416
WiFi IP address 192.168.2.15
WiFi signal strength -69dBm, reconnections 0, sleep mode modem

i see my wifi strength is not great -69dBm, but i dont think this has anything to do with it.
For example if i upload file it just works fine even with really big ones,
i missed the number of AJAX retries setting, it was set to 1, changed to 5 and it is a bit better,
But i still get disconnects.
Maybe i set it to a really high number.
But it doesnt really fix the problem i think it just makes it workable
oke with AJAX retries set to 50 i was connected for 5 minutes. but then i get the AJAx error
and i could not reconnect again it looks like web server is just down . My browser gives me this error : ERR_CONNECTION_RESET
When i send ping to the Duet it does reply so it does have a wifi connection.
is there a special procedure to go back to the old firmware ?
i think the last working version (for me) was :
Have you tried both versions 1.20 and 1.20+1 of DuetWiFiFirmware?
i download this version : https://github.com/dc42/RepRapFirmware/releases/
Where can i get the 1.20+1 ?
I prefer to go for the latest version that didnt have the disconnect problems .
i see on this board users who have this 1.20+1 version and the are also reporting disconnects.
I dont have a panel due connected so my only option to print is with the webinterface.
i will upload the old firmware today and hope it will work.
i installed the old firmware, and untill now i didnt see any Ajax erros .
it looks like there is a bug in the 1.19 and later firmware. or my board is broken.
would be nice if this is fixed so i can also enjoy the new features.
its running for 5 hours now and still no AJAX errors.
So im happy i can print again, but if its not fixed , im stuck with old firmware….
