DuetWifi - Connection error

[Lars_A]

Hello,

I'm getting "communication error" and "Error" more or less all the time but I can't figure out whats wrong.
Sometimes I'm able to reconnect but usually I need to restart or sent M999 (Reboot) via panel due to be able to reconnect.
By rebooting and upload files, reboot and so on I'm able to get prints started but it usually gets disconnected in the beginning of a print.

These are the messages I'm getting
"Error": https://www.dropbox.com/s/grm3wekao07zr80/Sk%C3%A4rmavbild%202017-02-15%20kl.%2020.32.07.png?dl=0

Any idea what can be causing this?

It sounds to me that you have a weak wifi signal or interference at your Duet WiFi. This thread https://www.duet3d.com/forum/thread.php?id=861#p8499 may be relevant.

The signal is as strong as it gets. I'm using a Asus ac66 router. I've tried 5 different channels besides the automatic setting without any improvements.
Could I've missed something in the setup?

Which versions of DuetWiFiFirmware, DuetWiFiServer and DuetWebControl are you using? They are listed on the Settings page of the web interface.

Also please confirm that the browser is Chrome or Firefox.

I updated all fw yesterday and it seems stable in a way…. I lost connection in Chrome and when I tried to access the printer again the browser just sent me to Google... Very strange! When I tried with safari it worked just fine without disconnecting.
I also had a better auto tune of the heater which I had issues with before. Now I'm not getting a fault if I heat up the extruder and restart the machine.

Update: I'm still loosing connection. I had a couple of lost connections mid print today and I can't for my life figure out what it can be. I've tested turning off all sources of interference, changed network, choosing different channels and so on without any improvements…

Update: I'm still not 100% sure what could be causing this but I turned off my RaspberryPi on the other side of my house and I havn't gotten any connection errors today… That could be the interference source even if it feels very strange..
