DWC 2.06, Experiencing Connection Interruption Errors

[ctilley79]

This is happening on both of my printers. One printer is running RRF 3.01 beta 2, the other is running RRF 2.05. Getting the same error at random intervals, however all UI functions still work as intended. I'm still able to upload successfully to both printers without error.

Upgrade to DWC 2.0.7 and see if that fixes the issue

[ctilley79]

Will do. Damn you guy's move fast. must have been released today

[ctilley79]

@jay_s_uk Actually that didn't seem to fix it.

[dc42]

Do you have a password set on that Duet?

[ctilley79]

@dc42 no. I live life dangerously

[A Former User]

[ctilley79]

@bearer yes it is a duet 2 wifi

@bearer

This is from my Ubiquiti Access point dashboard. It's showing that neither printer has dropped connection to the network.

@ctilley79 said in DWC 2.06, Experiencing Connection Interruption Errors:

Ubiquiti Access point

that should rule out connection issues. And it also confirms you're running
DuetWiFiServer 1.23 which i believe is the correct version. (Someone will probably be along shortly to correct me if I'm wrong, Icouldn't find the refrence I was looking for with a quick search)

[smoki3]

I also get alot of these issues with 2.06 and 2.07

[mwolter]

Same here, with a Duet 2 Ethernet rev 1.04 running RRF 2.05. Constant reconnection messages and approx one hour into a print I lose all access to DWC. I can still ping the board, the print continues fine and PanelDue continues to work fine. Did not have issues with version 2.04.

[mwolter]

@mwolter Updated to DWC 2.07 and it appears to have helped with the web interface becoming unresponsive. There are still a lot disconnection notifications in the console but at least I’m not locked out of the web GUI. Interesting thing, I don’t notice the disconnection pop ups as often. Prior to 2.07 it was common to see them if DWC was open and in focus. Now I don’t notice them as much but there are still quite a few in the console. Could this be because the Mac doesn’t give priority to safari when it’s minimized? BTW, this is with the lates MacOS and Safari.

[ctilley79]

@mwolter That's what I'm noticing as well. Seems the disconnect notifications in the log aren't affecting usability. Just annoying
