wireless networking - How can I capture other computers traffic in Wireshark on a WiFi-network?

I run Wireshark on a MacBook Air and I also have a Android phone on the same WiFi-network. If I visit a website with the Android phone I can't see that DNS-traffic (or other traffic) in Wireshark on my MacBook Air. Is there any way I can capture all traffic on the WiFi-network in Wireshark?
