Q: Air drop

Does your Macbook meet:

Use AirDrop to send content from your Mac - Apple Support

Have you powered off and then back on your router?

Have you turned on AIrDrop on the phone?

Did it work before?

What router do you have?

Are you the administrator of the router?

A computer can't meaningfully pair via BT to an iOS device with apps on each device.

You can try resetting the router and resetting it up.

Also it doesnt even get paired with mac

There is nothing in current iOS and OS X that requires "Pairing." All connections are made automatically.

Does your router provide both a 2.4GHz band and 5GHz band under the same SSID? If so, can you configure it to show them as separate networks? If so, try that and make sure they are both on the same band.
