1 As wireless station Y moves from the coverage area of access point P1 to that of access
point
2 P2, it scans and uses the signal of access point P2.
3 Access point P2 acknowledges the presence of wireless station Y and relays this
information to access point P1 through the wired LAN.
4 Access point P1 updates the new position of wireless station.
5 Wireless station Y sends a request to access point P2 for re-authentication.

6.4.1 Requirements for Roaming

The following requirements must be met in order for wireless stations to roam between the
coverage areas.
1 All the access points must be on the same subnet and configured with the same ESSID.
2 If 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.
3 The adjacent access points should use different radio channels when their coverage areas
overlap.
4 All access points must use the same port number to relay roaming information.
5 The 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
