The UM3 won't work with USB, neither connect via WiFi or LAN.. Every time I try to run wifi setup I get thrown back to the main menu. Same thing happens when I try to push print with usb..
Just bought the printer and it has been working for a while over wifi only, but I lost connection frequently during prints.. It has never worked via lan cable..
I tried to run a firmware update (stable version) and it only got worse, now it won't work at all..
please help?!
