Slow Upload speeds using Web Interface

MCRikki

@jay_s_uk I just ordered a new Class 10 SD Card today to see if that is the issue or not. Just figured I'd reach out here to see if anyone could see anything else wrong that I could try in the meantime.

Upload that zip file to get everything up to date. If that and the SD card don't help though it seems like it could be interference related. Are there many SSIDs in the vicinity? Or other sources of 2.4ghz radio signals?

@MCRikki upload it to system

@Phaedrux Replaced the SD Card and still having the same issue. Went with a Class 10 card. The weird part is that downloads are going at a normal speed (about 200kb/s). And when I try to push an upload to it, it starts around 150kb/s, and then just tanks down to about 12kb/s. It has a good connection to the access point, as the AP is right next to it.

Phaedrux

To eliminate the access point as a possible issue, can you test the Duet in Access Point mode, where it creates its own network that you connect to directly?

@MCRikki to see whether the network speed or the SD card writing speed is the problem, run these tests:

Send M122 P104 to test the SD card write speed. You can if you wish add another parameter to specify the file size.
Take a copy of one of your large GCode files, rename it to end with ".dummy" and upload it, looking at the reported upload speed just before it completes. The file will be uploaded to the Duet but not written to the SD card.

I'm having the same problem, duet 2wifi, it's been going on for a long time and I've tried a lot of things to no avail, so I saw your reply here today so I thought I'd ask again. I prepared a 12mb file and changed it to .dummy and on the first two seconds the upload speed was 200kb/s then immediately went to 10kb/s then to 1-2kb/s. I've changed many class 10 memory cards and all new ones from sandisk, every time the same upload speed is only 1kb/s and the motherboard is right next to my router 0.5m with no cover in between. I've tried many versions of firmware and flashed the motherboard but still have the problem.

If you need any more information please talk to me, I would very much like you to help me with this long-standing problem. Thank you!

@Yapeng maybe update the RRF and WiFi firmware versions to the latest ones. 3.3 and 1.21 are old now

Yapeng、

@jay_s_uk
Thanks so much for the advice, I've upgraded but the problem persists!
I also tried uploading a gcode file of less than 1mb, and although the speed was still only 1kb/s, I found that when it showed uploading to 100%, it started uploading from 1% again and by then the speed had dropped to 500b/s. Then after a few tens of seconds it showed that the upload had failed! I have not been able to use my printer for a long time because this motherboard has not been able to upload my files, It used to work fine and to my great satisfaction, I don't know why all of a sudden it started not uploading files!

@Yapeng check your SD card for free space and possibly other problems: see https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#troubleshooting-sd-card-issues

If in doubt, replace the SD card for a higher performance one. See our recommendation here: https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#specification

@droftarts thanks, I've changed many class 10 memory cards and all new ones from sandisk, every time the same upload speed is only 1kb/s and the motherboard is right next to my router 0.5m with no cover in between. I've tried many versions of firmware and flashed the motherboard but still have the problem.

@Yapeng the slow upload when you change the file extension to .dummy indicates that the issue is nothing to do with the SD card.

My guess is that there is an incompatibility between WiFi module on the Duet and your WiFi router/access point. Here are some things you can try:

Try upgrading the WiFi module firmware to 2.1beta6 from https://github.com/Duet3D/WiFiSocketServerRTOS/releases/tag/2.1beta6
Try a different router/access point
Check which channel your router/access point is using. You router WiFi configuration or status page may tell you, if it doesn't then use a WiFi scanner app on a smartphone. If it's operating on channel 1 then change it to a different channel, e.g. 7 or 11.
