my way to upload gcode files, my way to use my printer is to upload gcode files through usb with M559. Most of the time I have a program reading the usb serial port. There's no specific wifi debug messages.

M111 P14 S1 has been in my config.g for months...

Yes, but do you have a PC connected via USB to receive the debug data? If you do then you should see some messages when the WiFi module starts up. If it detects a problem, you may see further messages.

You should most definitely not use M111 P14 S1 if you do not have a PC connected running a termninal emulator or Pronterface etc. to receive the USB data.

I have a raspberry connected to the usb, reading the usb port all the time.
I can see the ssid list, and the connection getting successful, after that, there isn't any specific message, no error, no reconnection.
Same goes if I enable storage/network/webserver debug, I can see the connection, data being received from network, data being read/written from/to sdcard, but no specific error when the TCP connection is reset.

M111 P14 S1 is in my config.g because my rpi is always connected and reading the usb serial port as this is my only way to upload files with M559.

I also tried to unplug rpi + disable any log, I still have the tcp issues.

I'll check my sdcard cluster size this evening, and I'll try to reproduce with another AP, No need to move my duet to a friend, I'll use an android phone as an AP and will connect my pc to it. I'll do that with the sdcard I'm using atm, I'll do it again with the brand new sdcard I used last week to diagnose sdcard issues.

Will report back as soon as done.
This duet board is a replacement board I bought from T3P3 2 years ago after I shorted 24V and 3.3V...

This is what I get when I have a terminal session connected to a Duet WiFi and I use M552 to disconnect and reconnect while WiFi debugging is enabled. You should see something very similar, with ***** replaced by the SSID of your network.

@dc42
yes that's obviously what I've also been getting.

and this is what I get after I just powered on the printer and tried to upload a 25MB gcode file, which was obviously unsuccessful.

I'm sorry, that's not obvious at all, because you didn't say you were getting any debug information at all. Which led me to think that you were not monitoring the debug output.

Let's see what happens when you try using your phone as an AP.

lolorc

Hi,

Good news, it's not my esp as it's working flawlessly with my android ap.
So I guess I need to investigate what's going on with my cisco APs (2 of them, Multiples SSID, etc...)

Sorry for the noise,
Thanks for the patience and answers.

I'll report back as soon as I find something relevant.

Would this buffer problem explain why I have been experiencing problems uploading files to my first ever Duet2 WiFi?

I've had various manifestations of the problem: once a failed save of an edit to config.g in the browser, several times starting an upload of a g-code file and then seeing the transfer stall after a couple of MB and then error out.

The first time I had trouble uploading a g-code file, rebooting solved the problem. The second time, even a reboot and immediate re-upload resulted in the transfer stalling and terminating with an error. When that happened, I shut down, powered off and put the SD card in my Linux laptop. I checked the file system on the card (and cleared the dirty bit) and read the entire card with dd without issue.

My hardware is a genuine Duet2 WiFi from duet3d.com in the UK. When I got to testing my new printer just before Christmas, I updated both the Duet and the PanelDue 7i that I have to the latest releases of their firmware when 2.02 was released.

Everything works fine except for these spurious file transfer errors.

It's hard to know for sure what conditions could cause the WiFi module firmware to run out of buffers, other than the condition that DWC 2.0RC2 was good at triggering. I do know that some users experienced more disconnects when we switched to the new WiFi firmware architecture, which is probably when the buffer exhaustion problem started. However, we also adopted the new SDK from Expressiv at that time, and that included some major changes including adjustments to the output power.

So I recommend that you upgrade to the 2.02a firmware bundle, which includes DuetWiFiServer 1.22. In particular, if you are already running DuetWiFiServer 1.21, then upgrading it to 1.22 is low-risk.

I have two cisco APs, I've disabled the 2.4GHz network interface on my a1140, letting only the 1600 two floors under working, it also works better !
I guess I'll find a way to get another a1600

@dc42 Thanks. I'll be doing some more tuning on the printer this weekend, so I'll update first and keep an eye on it.

If I do still get the problem after updating, what kind of information should I collect to help diagnose the cause?
