Help! DWC Disconnects and Drops after extensive troubleshooting
-
Thanks for the suggestion!
I would love to try that, but am completely unaware of how to go about doing it. Do you know if there's any kind of write-up on how to do this?
-
see
https://duet3d.dozuki.com/Wiki/Gcode#Section_M552_Set_IP_address_enable_disable_network_interface2 = enable networking as an access point
-
Thanks!
I'll give this a try this evening and report back.
-
No success.
I tried running it in access point mode with no success. I also upgraded to the latest DWC, and still no change.
-
Which version of DWC are you using? DWC2 is in some ways more demanding than DWC1.
Some possible reasons for the WiFi behaviour changing:
- You have acquired another device that uses the 2.4GHz band, e.g. cordless phone or baby monitor
- Your close neighbours have got a new router, or changed WiFi channel
- Your router is set to automatic channel switching and has changed channel.
I suggest you check which channel your router is set to and try changing it. There are smartphone apps that will show you which channels are in use.
Also use M122 to check that you are running DuetWiFiServer version 1.23.
-
Thank you for your response!
I've attempted to update the DuetWifiServer to version 1.23, but cannot get it to go past version 1.21. I've tried uploading it directly through the DWC and by drag/dropping it into the /sys folder and applicable folders within on the SD card. I've also tried multiple SD cards to see if my problem was a bad SD card.
I will try changing the wifi channel and report back with my findings. As far as new devices go, there is nothing else new on the network that was not previously there when it was functioning correctly.

what is the error message?
-
No error message.
When doing it via the DWC, it acts like it's going to take but then never restarts completely. I get prompted to install the firmware, select yes, and then it does its thing but freezes. I've left it completely alone for upwards of 20 minutes after uploading the new firmware and it never recovered or rebooted on its own. I have to physically cycle the power and then once rebooted it is reverted back to 1.21.

Also,
@dc42 changing the wifi channel had no effect.

please see

try upgrading via usbthe wifi firmware has to match the duet firmware.

@Veti
I was able to successfully update the firmware to the latest versions, to include the wifi firmware.Seems like the problem may be resolved, but it's too early to tell just yet. I'll report back either way in case someone else finds themselves facing this issue as well.
-
It seemed to improve for a time, but has since worsened.
DWC constantly disconnects now to the point that it's impossible to make changes in my config.g file without powering down and removing the SD card...
Any ideas or further troubleshooting tips would be greatly appreciated. What are my options for being able to print if I'm unable to restore DWC functionality?
-
Please confirm which versions of the main firmware, DuetWiFiServer, and Duet Web Control you are now running (as reported by Duet Web Control), and the WiFi signal strength reported by M122.
-
@alexd607 WiFi can be a real pain. Not sure it's a network issue but it would be good to rule it out with a simple ping test while the issue is occurring. https://iihelp.iinet.net.au/How_to_run_a_ping_test
It would also be good to leave the ping test running to see what the packet loss is over time.
-
I'll be sure to give this a try and report back with what I find! At this point, anything is worth a shot.

That's interesting. Are you having problems with the filament sensor? Is the wiring running close to stepper motors or PanelDue (if fitted)?

I don't have a filament sensor or panel due fitted.
It's strange that that is what it's reporting considering the last reset was done by me via M112.

Strictly for troubleshooting, have you considered putting the printer in Access Point mode?
Then testing with a phone or tablet or laptop a few feet from the printer, then further away, etc. Then with the mobile device in the next room... then near the router... etc, etc. A demonstrable "map" of connectivity.
This type of testing removes your home network from the picture. Once you've verified that the DWC is (or is not!!!) stable from various distances when the link is direct printer<>device, you can go back to making it reliable on your home network, with some data points in your mind about the printer's basic physical capability to wirelessly reach various places in your home.
