Just tested here. When I switch to LAN only, I go into Studio, Device and click on the device. It is still available and I can home the printer for example. Printer needs an active WLAN connection of course.
Yes, I got that message and clicked Yes. However in Bambu Studio, no other devices are listed to connect to. I only have one home wifi network, both printer and laptop (on which Bambu Studio runs, Win 10) have iP 10.0.0.x addresses…and I an ping the printer through Win 10 cmd line…
I played with the settings but still unable to make it work, obviously there must be a solution since several person succeeded.
What would be useful for the futur is a quick diag tool on the Studio app side, we manually enter the IP of the printer and we get an error code/description of what could potentially prevent the app to discover or connect to the printer.
I read somewhere that one solution could be a complete restart, i.e. log off the printer from the account and start from scratch, as if you had just received the printer.
