Hello CliveHarvey,
Thanks for posting your concern here.
In this case, please uninstall the network adapter. Go to Device Manager > Network adapter > Right-click all the network adapter and select uninstall. Check the box saying delete the driver. Then, run Surface Diagnostic Toolkit and check for Windows Update.
Update drivers and firmware: Check what is the current OS Build of your Windows version by typing winver on the search bar near the Windows logo. Go to Download driver and firmware for Surface, choose (your Surface model) then click Download. Choose the .msi file that matches or nearest to your current OS Build and click Next. After downloading, run and install the .msi then Restart.
Also, see Fix Wi-Fi connection issues in Windows for more troubleshooting guide.
Hope this helps.
