WLAN shuts off at printer

I have a new X1 Carbon that will connect to my WLAN every time but will not stay connected. It will pass the network tests and the WIFI signal is strong at the printer. I have checked the antenna and it is connected properly.
After I return to my computer it will connect to the printer, but after a few minutes to an hour or two it will disconnect. When I go to the printer the WLAN toggle is off. If I turn it on it works again until it decides to shut off again. I have tried every solution I could find here to no avail. I have a tp link router hard wired as an extender with dual band and both are turned on and have different names. The problem is the same in LAN only mode.
Anyone know what to do before I put in a ticket?

Did you find a solution? I just got my bambu x1c yesterday and the wlan won’t stay on for more than ~ 10 minutes at a time.

No, I put in a ticket and have had no response there either.

Drat! I’ve put in a ticket too, fingers crossed for a solution.

Bambu helped me determine that the AP board was the cause. I replaced it under warranty and that solved the problem.
Thank you Bambu Labs support.

Ditto! I also replaced the AP board and now it’s working great.
