Bambu A1 Mini network timeout

I submitted a ticket for this previously. Bambu reported that it must be a network configuration issue - although nothing else lost connection - and closed the ticket.

I’ve done everything they asked.

I split my WiFi network into isolated 2.4/5 channels, and moved Bambu to the 2.4.

I did a full factory reset.

I reinstalled the previous s/w version.

NOTHING.

Device times out when printing. And it takes FOREVER to even find my printer.

The Bambu sits on a shelf next to a low-cost Epson printer that has never lost connection to the network once. Finds it, sends/receives updates, prints without an issue.

This is not my local network’s problem. But Bambu seems to be hanging me out to dry with a printer I can’t use the way it’s supposed to work.

Really regretting this purchase right now.

1: Have you checked your Firewall settings..??

2: Is the Network Plugin installed in BS or Orca..??

Yes to Firewall check. All ports open. Network Plugin is BS. Worked fine for a year. Now it refuses to print and times out.
