ABSTRACT:
A method for retaining network address of a wireless client device as the device roams between different access points operably connected to a single gateway is described. An embodiment comprises maintaining a table in the gateway memory containing the unique identifier of the wireless client device sent with each data packet. In addition to, the unique identifier, an entry in the table in the gateway memory includes the communication pathway established between the gateway and the wireless client device. When forwarding a data packet from the WAN to the wireless client device, the gateway uses the table in the gateway memory to determine the correct destination path for the data packet instead of relying on the destination address attached to the data packet.
