Hi Gavin O,
Thank you for reaching Microsoft Community.
I would like to confirm first on the exact model of your Surface. Is it a Surface Studio, Surface Studio 2 or a Surface Laptop Studio? See this page for reference: Find out which Surface model you have - Microsoft Support.
May I know what is the Driver version of the Intel(R) Wi-Fi 6 AX200 160MHz driver that is currently installed on your Surface?
When did the issue starts to occur and where there any changes made on the device prior?
When you uninstalled the driver from Device Manager, and it automatically reinstalls an older driver, does the error disappear or still not?
I'd love to provide you with the troubleshooting steps right now to fix the problem. I am afraid that we may have to wait for the above answer first so that we can provide the necessary information. Once we collect all the information, we will formulate the feasible resolution to help you with your case or if we need you to refer to the support that suits your problem. We will be sure to let you know in advance so that you save time.
Kind regards,
Marrion
