Slow moving files and disconnects WIFI
jevs last edited by
I cannot seem to solve communications issues.
It has always been very slow to move a file to the printer and if the file is very big it times out.
It has also dropped part of the file and then I don't notice until the print stops with the nozzle burning into the print. When I look I realizes not all the layers are showing.

You might find some things to try here: https://duet3d.dozuki.com/Wiki/WiFi_disconnections_and_AJAX_timeout_errors
Your signal strength looks ok from that M122, but it could still be getting interference in a crowded wifi spectrum.

I have done some more troubleshooting and there seems to be an issue with it's communication to the WIFI system we are using here at work with the printer.
I set my phone to a WIFI hotspot and connected to that fine and moved files over at a proper speed (500-600 KiB/s).
The speed on the regular Wifi bottoms out at about 10 KiB/s, so there is something going on with that communication. The IT guy is looking into it further.
From the router side so far it is reporting that everything looks good from what they checked so far, but there is some thing amiss.

I had a range extender put between the modem and printer (it's on opposite sides of the house) It was fine up until yesterday, it would connect, but disconnect when attempting to upload. I removed the extender and boom! everything is peachy.
Also make sure you reserve the 2.4 band for the printer if you can, and run all else on 5.8.
