A computer system allows two devices operated by two users from a plurality of trusted users to establish a direct peer to peer wireless connection based on a social network connection. An online system uses social network connection information to determine trusted users for each of the client devices, and monitors the geographic locations of the client devices. Responsive to determining that the client devices are within a predetermined distance from each other and are trusted users for each other, the online system transmits connection information to the client devices, prompting the client devices to establish a direct peer to peer wireless connection through which content can be transmitted.
