other devices can't find my network when i do "create network"
MacBook Air 11-inch, Mid 2011
when I use the create network tool in the wi-fi dropdown at the top of screen, and i create network, none of my friends devices can find it, no mater how close they are to my computer.
when i go to console this is what instantly appears when i create the network:
