A wireless device includes first and second wireless network interfaces, first and second address determination modules, and a mobility control module. The first interface establishes layer two connectivity with a first media access gateway. The first address determination module assigns a first address to the first interface in response to a first address assignment message received from the first media access gateway. The second interface establishes layer two connectivity with a second media access gateway in preparation for a handoff from the first media access gateway to the second media access gateway. The second interface transmits an address request message, indicating a desire for the first address to be assigned to the second interface, to the second media access gateway. The second address determination module assigns a second address to the second interface in response to a second address assignment message received from the second media access gateway.
