Duet 2 WiFi Disconnecting



  • A new Duet3D, my first one. Followed the initial setup using a Windows computer.
    The problem:- "A communication error was reported, so the current session has been terminated. Please check your board and try to connect again." This happens all the time.
    Spent a few hours searching the troubleshooting guides. Disabled 5Ghz on the modem and signal went from -56 to -44dBm, but no effect. The M122 diagnostics seem good.
    Curiously, disconnection always occurs at a time finishing in 54 seconds i.e. hh.mm.54 seconds - so a connection never lasts longer than a minute.

    Update: I suspect it is a Windows problem as when I used an Android Tablet (including simultaneously with Window Laptop using either Firefox of Edge) Duet on Android seems to stay connected whilst disconnected in a Windows Browser.

    We recommend using either Chrome or FireFox browser under Windows. last time I tried Edge it was mostly working but there were a few glitches. However, that was some time ago, so they might have been resolved since then.

    The "54 seconds" observation is interesting!

    Which firmware and DWC versions are you using? Look on the Settings General page of DWC to find out.



  • With the exception of the 54 seconds (I did see this but can't say its consistently every xx.54 seconds.) I am getting constant connection failures as well on the latest version 2.01.

    With a fresh connection on the duet and a fresh connection from mac osx Google Chrome I get a connection for a couple of minutes but after that I get a disconnection and EVERY subsequent connection attempt fails. I can even open the Chrome developer tools and do a hard refresh and clear the cache with the same result.

    If Chrome doesn't even open the debugging console, that sounds like a problem with Chrome. Is it normally reliable on Mac? I don't have a Mac but I understand that Safari works with DWC too.


 

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