A gateway server manages connections in a wireless local area network (WLAN). The gateway server provides context information, such as an IP address, that is stored after being previously allocated to a mobile device in a previous connection to the WLAN. The gateway server reassigns the IP address to the mobile device after it reconnects to the WLAN after a disconnection, thus providing seamless roaming for the mobile device from WLAN to WLAN (or subnets within one WLAN) without requiring the user of the device to re-register. The gateway server also provides cluster information (e.g., as part of the context information) for a mobile device making a new connection to the WLAN, such as access privileges associated with the cluster of users of the mobile devices. The gateway server also provides load balancing among two or more WLAN's by directing a newly connection mobile device to another WLAN (or subnet), if less congestion results.
