Duet Wifi-Establishing Wifi connection requires multiple resets



  • Most, if not all from that article do not seem to apply to my situation.
    I have been through the steps listed that could possibly apply with no success.

    Signal is strong, Duet is wired in a plastic (printed, PETG) box sitting on the work bench (wood) 200-300 mm away from the printer and 500+mm away from everything else. there are no wires running near that part of the board and there aren't any other obstacles (including a lid to the box) in the way. The box is stationary. Eitehr I have to initiate a terminal session and issue M552 S1 multiple times (3, sometimes 2, sometimes 4 usually no more than 4) or by pressing the reset button on the DUET 3 times (sometimes 2, sometimes 4 usually no more than 4) the wifi will work. I have the timing down,

    press reset
    after a count of 1, blue flash from wifi module
    after a count of 3 second blue flash followed by steady blue
    all good

    if no second flash after 3 count press reset, follow procedure until led is solid

    Once on the network, I rarely have issues. In fact I cant recall any issues except for the timeout message from the browser if I walk away for awhile and come back. Browser reconnects as expected when you press connect. I printed from Repetier Server over the network with no issues either, 3 hour print. I can connect anytime from multiple devices. I'ts only at boot (cold or warm)

    Everything is configured as it should, I cleared out all networks and started from scratch weeks ago.

    Originally I would use terminal with multiple (3 to 5) M552 S1 commands (pausing after the first blue led flash at boot waiting on the second flash and steady blue led from the wifi module).

    That was really annoying so out of frustration I tried the reset button and after 3 press (possibly 4, it was a few weeks ago) the wifi came to life just like the terminal, multiple M552 S1 commands. It's easier than having to connect usb, launch termainal, ......

    I'm concerned that I'll wear out the reset button or accidentally hit the ERASE button.

    There are rare occasions where it works without my interaction, but <10% of the time, possibly <5%.

    I use my printers daily so this is an everyday occurrence, multiple times a day since I've been configuring and dialing in the printer and firmware parameters.

    Signal is strong

    1. How strong - when you have established a connection, what is the RSSI reported by M122?
    2. Which version of DuetWiFiServer are you running? Look in the Settings/General page of DWC to check.
    3. Please share your config.g file.

    I suggest upgrading these for starters. I don't know that that would help your issue, but it's something to try.

  • administrators

    I agree, upgrade those first.

    If the problem persists, please connect USB, try sending M552 S1 a few times, and let us know what error message it reports when it fails to connect.

  • As requested I updated to the files linked in the post. Smooth and simple. No change though. at least it's consistent.


  • administrators

    I've never see this fault reported before, and your reported signal strength looks reasonable. So I think there must either be some incompatibility between your router and the ESP-12S WiFi module, or the wifi module has an unusual fault. If you wish to ask your supplier to exchange your Duet, I will approve that.



  • I bought the board direct. Left over v1.03. Did I make a mistake with the going with the old board, the cost difference is insignificant I sort of feel I made a foolish purchase thinking it was a significant savings.


  • administrators

    There are no differences in the WiFi support between 1.03 and 1.04 apart from some layout changes to reduce EMI.



  • That was more of a general question and (mostly) unrelated to the issue.
    What is typical in this situation, did I really mess up by buying this "deal" direct?
    I have to ship the board back to the UK at my expense? (i'm in the US).
    or is that a question for Duet3D.com (or is that you?)



  • I'm nit sure if this applies, but I was having trouble connecting my printer to networks other environments other than my home.

    Ultimately, I told my Duet to forget all of the various networks that it thought that it knew, and put in only the 3 that I will personally use.

    It comes factory configured to a wifi network, which I assume is the one that is used for testing (With a static Ip, 192.168.1.14, if memory serves) and it might have more, depending on what you've set up with M587.

    Take a look at the output of M587 with no parameters. I think that it will show you all of the networks that it has stored.

    you can then use M588 to have it forget some of those networks. I'd suggest that you tell it to forget everything except "SpicyNacho" and see if that clears things up.



  • @supraguy That's actually one of the steps from the network troubleshooting wiki posted above.

    If unable to connect to your wireless network at boot up, try deleting all saved wifi networks with M588 "*" (That is, using an asterix for the network name), then re-adding it with M587. For example, M587 S"networkname" P"password".



  • The basic network stuff has all been addressed. This is seems to be beyond that.

  • The board has been replaced (incredibly fast) and is in operation.
    Upgraded from the 1.03 to the current ver (1.04)

    Out of the box, cabled, with the restored files backed up from the original board
    I started a terminal session (YAT)
    M587 (List stored networks)
    M588 "what ever net name was there" (M588 S"*" didn't work for some reason) (cleared existing stored networks)
    M587 S"SSID" P"NetPass" (set my network wifi credentials)
    M553 S1 (launched wifi, obtained IP adsdress)

    Found device IP and connect to DWC via Chrome

    Shut power to board waited 10 count reapplied power

    Same issue as the v1.03 board, no wifi (blue LED flash just after power up and ~1 count)

    Pressed reset blue LED flash wait ~10 count
    Pressed reset blue led flash, followed by 2 more then steady

    I updated board as before, except all in one pass
    Duet2CombinedFirmware.bin 2.02RC2(RTOS) (2018-09-07b2)
    WiFi Server Version: 1.21RC4(08b3)
    Web Interface Version: 1.21-RC4

    All seems to work as it should!!!

    I restarted many times and it HAS NOT repeated the behavior.

    I just finished a 2 hour print and restarted the board both from the power switch and the Emergency Stop button in DWC.

    So far so good.

    The wifi (LED) behavior is different compared to the last board

    I am also getting different print results. i have to print more to know for sure, but a model that I've been having issues with actually printed the best it has since I changed to the DUET. It has some ringing that it didn't have before but overall it's printing better. No setting changes were made. (ringing might be machine related)


  • administrators

    I'm glad it's working.

    You are running old RC versions of DuetWiFiServer and Duet Web Control. I suggest you upgrade them to released versions.


 

Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
