HTTP connection over wifi gets dropped
-
I have TWO RailCore printers driven by DuetWifi controllers. BOTH started this issue where I can conNECT just fine to DWC. But if i upload a gcode file tp print, it will get part way through and the connection drops. It's apparently my home wifi. Embarrassingly, I'm an IT guy and I see nothing wrong with it. No recent changes either.
As a troubleshooting step, i wanted to change the Wifi to a different access point, using the M587 command. It takes the command and does do anything. How do I change the wifi, and and any ideas on the HTTP drop? -
@StevenL Which versions of RRF and DWC do you have installed? Also, please run M122 and share the result here.
In a first step, follow this WiFi troubleshooting guide. You also should be familiar with this doc: Setting up networking on Duet.
The syntax and usage of gCodes is listed in the GCode dictionary. See M587 and M588. -
@StevenL said in HTTP connection over wifi gets dropped:
How do I change the wifi
Adding another network to the remembered list won't automatically make it switch to that network by default. Instead it will connect to whichever network has the best signal strength. To force it to connect to a network you can include the network name in the
M552 Pcommand. Or use M588 to clear all the networks and re-add only one with M587.The Duet is only capable of 2.4ghz wifi. Perhaps your APs are trying to use band steering to 5ghz when it starts a file transfer.

@infiniteloop I am running 3.4.3 on both.

Please try updating your firmware to 3.4.6
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.6/Duet2and3Firmware-3.4.6.zip
There is a new wifi firmware included in there as well.
Do you know if your AP has band steering?
