this thread been created earlier in this topic

the setup works just fine most of the time but sometimes it disconnect and connect again in the middle of printing file.
when it happens the connection is lost and the print file is stopped and the printer need to do homing again.
this cause the print to be sent again and start from starch.
i check my internet connection at the wall socket with different cable and it seems to be fine.
no error messages

is there any reason that the duet doing connection reset in some times?
why is that?
should i do something to improve it?
maybe its a configuration error?

will be glad for any help.
thank you
