Duet Wifi unable to upload files

dc42

What are the symptoms when you try to upload a file?

Steps to recreate my problem would be:

Click upload&start
Select file
Dialog appears, shows some small amount of file instantly uploaded when using Google Chrome, then immediately freezes. If I use Edge, it never even upload the first chunk instantly.
Timeout, upload gives up and throws error

The strangest thing is that it seemingly randomly might let me upload a file every once in a while. Sometimes it even behaves for a while. Its been behaving pretty well after making this post, even though I changed nothing. I'm sure the problem will come back though.

Are there any potential sources of radio interference during the times the uploading doesn't work? Do you live in an apartment building? Is their wifi congestion in the area? Microwaves or 2.4Ghz wireless phones being used? Are there many people in your own house using the same wifi network?

Please test writing to the SD card by sending M122 P104. You can optionally add an S parameter to specify the file size in Mb, default 10.

Also please update your WiFi firmware (DuetWiFiServer) to 1.22 or 1.23. Your M122 report shows that you are running 1.21.

No interference, and the ESP8266 is basically within 2 meters of the router. I even tried using a WiFi extender to basically make a network entirely dedicated to the print which did nothing.

I've tried every firmware you've mentioned here and none worked. I tried rolling back since the problem has only gotten worse over time. 1.22, 1.23, and 1.21 are all the same.

M122 Results: SD write speed for 10.0Mbyte file was 2.62Mbytes/sec

Please update DuetWiFiServer to 1.22 or 1.23, then confirm using M122 that the update succeeded:

WiFi -
Network state is running
WiFi module is connected to access point
Failed messages: pending 0, notready 0, noresp 0

There is a known issue in 1.21 that causes problems with a small number of routers.

Ok I have updated back to 1.23. The problem randomly stopped happening sometime last night as it normally does, maybe by some act of god it won't come back.

If/when the problem comes back, a WireShark trace of a failed upload may help diagnose the reason.

Good idea, I'll have to try that next time. Appreciate the help and have been in love with my Duet for almost 2 years now! Thank you

@dc42 This is almost a year old, but I am now having this issue. I cannot upload files to my Duet WiFi from PrusaSlicer any more, but was in the past. I have changed routers and seeing that 1.21 had issues with some routers, I'm thinking it may be similar. It also fails when using the Upload button in the web interface. It doesn't fail at the same location.

How do you do a WireShark trace?
