Interesting. IF you go to this page https://duet3d.com/wiki/Getting_connected it says that "this connection process sometimes goes wrong"

Thats exactly what happened. I updated all the firmware and left the web interface at 1.12 seems to have fixed the problem. I just hope its not a reoccurring problem.

Ive been running my new duetwifi board flawlessly for about 2 weeks. I built a custom machine with a 1000mm^3 build size so the gcode files can be up to 9mb in size. Iv been uploading them with no problem up until now, however, now the machine times out when i upload files greater than 4mb. I haven't made any setting changes and my network hasn't changed either. Curious if anybody else has experienced this and how to fix it?
