This publication describes techniques and methods to provide a seamless switch from one wireless network to another wireless network on a mobile device. The described techniques and methods include an on-device application capable of switching wireless networks (network manager) that leverages a hardware capability present in wireless chipsets allowing for a seamless switch from one wireless network to another. The hardware capability includes a chipset handling two concurrent wireless connections (e.g., a first (default) network connection and a second network connection) on different networks. If the quality of the first network connection deteriorates, the device can evaluate and connect to a second network. If the network manager decides the second network is a better connection, it will make the second network the new default network. The first network can stay connected until all ongoing transfers utilizing the first network have been completed. This switch will not use the cellular network during the transition and will decrease disruption for the user.
