Hi,
As mentioned in the title, I have had this issue with both 1.2.2.139 / 4.4 and the previous software version.
(I upgraded both the printer and the desktop software in the hope this issue would be fixed)
I can connect to the printer over WiFi, however after a second or two it disconnects.
If I restart the software a number of times, it seems like there is a chance to remain connected.
Please can you advise?
