Constant 'connection interrupted'
-
@Phaedrux Yes, was able to get the AP mode working and connected to it, same network drop problem. Will take a look at the link - thanks again
I think this is an indication of an issue "WiFi Vcc 3.45, reset reason Unknown" as it doesn't match the expected output
-
I left the Wi-Fi extender, for now, blasting into the ear of the DuetWiFi, as I don't see it hurting anything - other than the folks across the street
In desperation, as I don't really want to have to replace the Wi-Fi module - but will if required, I spent the morning redoing everything from scratch, just in case - no change. UNTIL I changed the "Number of maximum AJAX retries" from 3 to 4. No drops in the last 4 hours, for the first 1 1/2hrs I was re-leveling the bed - I mean why not - to see if raising the MCU temp was an issue - seems it was not.Usual KOD statement, but looks like the issue, possibly symptom only, was AJAX retry # brought about with a recent upgrade to Duet Wi-Fi 3.1.1. Which I had completely overlooked as a possible culprit. I had upgraded it but then not used the HEVO for awhile as I was using my MakerSelect IIIP.
Will see if I get any more connection drop outs now I have tempted fate again
-
Last post on this, I know everyone will be pleased
So, indeed it was the KOD - 30 mins ago back to constant drops again. Best get out the hairdryer, solder and BBQ tongs then......
Can you turn the DuetWifi into a DuetEthernet?

Yes I believe so. Instead of soldering on a replacement module you could install the socket for the ethernet module.
-
Hmm, OK that's an option then, except for the hole I'd have to put in my case
Oh wellThanks again Phaedrux

I don't want to steal this thread but I'm suddenly having similar problems. I just updated firmware from version 2.something to 3.1.1. At the same time switched from AP mode to client mode. With old firmware and AP mode, it never had a problem. Now I get disconnects about once every minute, almost as if something that's supposed to be doing something every minute to keep the connection alive isn't working. Here's a short portion of the console output:

WiFi Vcc 3.35, reset reason Unknown
Interesting, I see you also get the 'WiFi Vcc 3.35, reset reason Unknown' issueI hadn't used the AP mode until I ran the test I mentioned above, had zero issue with the Duet for years until now
Have you checked that the AJAX retires is set to at least 3?
-
@Foden Thanks, but where would I check/set that?
-
From the main page go to Settings and it's on that page - I think - just booting mine up to check
-
Nope, I was wrong, see attached pic
Machine-specific / then its under communication
-
@mrehorstdmd First I would try reflashing the wifi module.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/DuetWiFiServer.bin
Place that bin file in the sys folder of the SD card and then send M997 S1 over USB terminal or paneldue console. Should get a progress report of the flashing process.
Having these macros can make wifi trouble shooting a bit easier too.
Are you trying to use AP mode or client mode now?
-
Also double-check your sd card does not have issues (check it on PC, laptop, Mac etc)
-
Thanks all. I'll get a look at it again tonight and report my findings.
-
I'm running (or trying to) in client mode. I put the DuetWiFiServer.bin file on the SD card and ran M997 S1 via Yat and USB and it tells me that the file is not found.
Now M122 says the wifi module is disabled. I try M552 S1 and it says Wifi module is stopped.
The card seems to be OK- it works fine in windows and seems to work OK in the Duet board, except for it reporting that it can't find the DuetWiFiServer.bin file.
I rebooted the board with M999 then ran M552 and it says wifi module is being started.
M552 S-1 says wifi module is stopped
M552 S1 says "ok"
M552 says wifi module is being started- it never seems to finish, and there's no wifi connection happening. -
@mrehorstdmd That's odd. The bin file is for sure in the /sys folder? Maybe redownload it and give it another shot.
If you send M997 S0:1 it should try to do both.
When going from 2.x to 3.1.1 you went through 3.0 along the way?
-
@Phaedrux yes, I installed 3.0 first then 3.1.1.
-
@mrehorstdmd I have had similar problem with the wifi module after updating from 3.0 to 3.1.1 but reflashing the module was able to get it working and I've seen similar reports and reflashing worked there too. So I'm hopeful that if we can get it to reflash the wifi server firmware it'll start working again.
-
@Phaedrux I'll try a different SD card...
-
@mrehorstdmd aybe it's the SD card- I tried to back it up to a folder in Windows and it gets 69% done then the speed drops to zero and it sits there. If the Duet board is having trouble reading it maybe the read times out and that's why it reports that it doesn't find the DuetWiFiServer.bin file.
-
@mrehorstdmd Sounds plausible to me. If you can't copy all the files off the card hopefully you can get the configs at least.
Doing a full format of the card might rescue it if there is enough spare over provisioning to replace any dead cells.
