Abstract
Systems and methods are provided to improve roaming performance and to minimize disruptions in connectivity. When roaming between a source AP and a target AP, the device determines whether the APs employ different gateways, such as through an ARP exchange. If the source and target APs have different gateways, a DHCP exchange is used to renew the IP address of the device to restore network connectivity.
