When switched on, a first WLAN mobile device is prevented from connecting to networks in a configured networks list stored in memory before establishing a peer-to-peer (P2P) connection with a second WLAN mobile device. Data transfer is performed from the first mobile device to the second mobile device over the P2P connection while continuing to prevent the first mobile device from connecting to the configured networks. After completion of the data transfer, the first mobile device is enabled to connect to the configured networks. Data transfer is performed more rapidly and with less battery drain. Connectivity information for the second mobile device may be obtained by reading a barcode on the second mobile device using camera equipment of the first mobile device.
