Unit was working fine for three prints earlier today. It then gave me “failed to connect to printer” and nothing was going through to it. I reset to factory settings and went through the setup again. The wifi is good. I have rebooted the printer and calibrated after the factory reset to no effect. I also tried to go to LAN only mode and it is also giving me Failed to connect to printer after the IP and Access are given. Anyone have a solution for this one? I am a bit stumped.
If you can try rebooting your router
No idea if this is at all helpful for you, but it was the cause of my problem when i lost connectivity to all my bambulab printers all of a sudden.
My home network uses 192.168.2.XXX IP addresses. Somehow the printers were on 192.168.0.XXX Eventhough only 192.168.2. addresses are being handed out by DHCP. Even reconnecting after a factory reset of the printer still gave them 192.168.0.
I had to go into the modem and force assignment of a 192.168.2. IP address to the printers. No issues since.
