Wireless interface not found on Rpi3 A+

I bought a brand new A+ last week, to replace a rpi zero W.

I updated the OS on the card before transferring the card over, and all seems to work OK, except for ‘Wireless not found’ in the applet on the desktop.

There’s nothing in sudo iwconfig

or sudo lshw -short

Any other clues? As I can’t see a lot of other issues being reported on the forums could it be a hardware fault?

Bluetooth does work.

Thanks
