Just to be thorough, I also went back to 3.4.1 and WIFI server 1.26. Still have an issue with the upload speed. Must be something on the ISP/router side that is creating an issues. You might see some more issues if this is the case.

Looks like upgrading to WIFI server 21.beta 3 fixes it though.

@velvia Unfortunately I went a different direction and abandoned the sensor less homing.

Finally figured it out, had an issue with it loading an old height map.

Found the issue by using the M114 command:
M114
X:255.000 Y:240.000 Z:10.710 E:0.000 E0:47.7 Count 79200 2400 4200 Machine 255.000 240.000 10.710 Bed comp -0.210

The Bed comp was set to 2.5mm, reran the bed mesh and it seems to have fixed the issue.

Just to be thorough, I also went back to 3.4.1 and WIFI server 1.26. Still have an issue with the upload speed. Must be something on the ISP/router side that is creating an issues. You might see some more issues if this is the case.

Looks like upgrading to WIFI server 21.beta 3 fixes it though.

@dc42 I was using 3.4.3 and 1.27 when I updated to the latest version.

On a side note. I have been updating two different SD cards during this process to ensure that I test both of those as well(they are different manufacturers formetted fat32, 64K unit size). A few after inserting the card and restarting the print it would hang on the connecting screen and never load. I would have to reformat it once I added it to the computer to check the files. Does this happen often?

Went through the suggestions:

1. Reverted the board back to version 3.4.1 but left the WIFI server the same:

This did not work. Same network issue as before on both SD cards.

2. My router will allow me to move the channels (I typically move it around to ensure I stay away from what my neighbors are using). It was set to channel 11, move to channel 8 and retested. Receiving the same network issues error and the upload fails. Again tried it on both SD cards with the same result.

3.Updated just the WIFI server to the new version 2.1 beta3:

This fixed the issue. It seems to upload just fine now...but why?

I went back to version 3.4.5 for the main firmware but left the WIFI server version the same. The upload speed is still working great.

Downgraded the WIFI server version back to 1.27, and the slow upload speed returned.

This doesn’t make sense though as it was working before. Maybe my internet provider updated the firmware of my router and that changed something on that side? I am not sure as I haven't changed anything on my end.

Are there any other tests I can do to help in bug fixing the firmware?

@Phaedrux you have ran into this issue before.

Here it is: Duet Mini Output - filtered.pcap.txt

@Phaedrux Here is the Wireshark capture. I scrubbed the results to make it easier to see what is going on.

Yeah, everything I am doing I try on both SD cards before posting anything.

IPs:
Desktop: 10.150.10.76
Duet: 10.150.10.40

Looking at the results, I am dropping a lot of packets between devices. The router is in the same room as the printer. I have not changed any of the network configuration before or after the software update.

The forum will not allow me to upload a .pcap file type. I might be able to message it to you directly?

I added a CSV version for now.Wireshark output.csv

@Phaedrux Shoot, yes, that is what I meant. Apologies.

@Phaedrux The wifi firmware is not changing it appears. I re-downloaded the DuetWIFIServer.bin from the link you provided and ran the M122 S1 command. The PanelDue showed that the firmware was being updated but the WIFI version is still 1.27.

@Phaedrux hmmm, reverted back to 3.4.3 and the upload issue is there as well.

Does these mean that something went bad in the board during the attempt to bring it to version 3.4.5?

@dc42 I was running 3.4.3. I read thru the upgrade notes between the various versions and didn't see anything that I need to change with the configuration.

Working on upgrading a Voron with a duet 3 mini WIFI(has a 1LC board as well) to version 3.4.5. Upgraded to the latest version and now I can't upload GCODE to the printer. It's starts out at 400ish KB/s then immediately jumps down to 10B/s which will eventually fail.

Looking over the forums I thought it might be a SD card issue. I purchased an additional SANDISK 8gig SD card. Formatted it to 64kb unit size FAT 32 per the guidance of dc42 on a few of the posts.

I have looked through everything related the to WIFI side of the problem and I'm not seeing an issue.
