Mac stolen in Pakistan
I'm sorry to hear about your MacBook Air being stolen.

While there is software built in to macOS and separately available to track, monitor, or lock a device, this software must be installed and turned on ahead of time. Once the device is no longer in your position, there is no way to remotely activate any tracking feature.

If you mean Wireless Protected Setup, this is a feature of Wi-Fi routers to make connecting to the wireless network easier. It would not help you recover your stolen device.

I can't say I know much about Pakistan's laws, but I would recommend providing as much identifiable information about your MacBook Air (serial number, MAC address, proof of purchase, stickers or other external marks) to the local law enforcement. If the device is recovered, I would hope they would contact you.

Good luck.
