The following requirements must be met in order for wireless stations to roam between the coverage areas.
1All the access points must be on the same subnet and configured with the same ESSID.
2If IEEE 802.1x user authentication is enabled and to be done locally on the access point, the new access point must have the user profile for the wireless station.
3The adjacent access points should use different radio channels when their coverage areas overlap.
4All access points must use the same port number to relay roaming information.
5The access points must be connected to the Ethernet and be able to get IP addresses from a DHCP server if using dynamic IP address assignment.
To enable roaming on your ZyAIR, click the WIRELESS link under ADVANCED and then the Roaming tab. The screen appears as shown.
