station may not be able to communicate with other wireless stations on the network and vice
versa.
Figure 6-6 Roaming Example
The steps below describe the roaming process.
1. As wireless station Y moves from the coverage area of access point P1 to that of access point
P2, it scans and uses the signal of access point P2.
2. Access point P2 acknowledges the presence of wireless station Y and relays this information
to access point P1 through the wired LAN.
3. Access point P1 updates the new position of wireless station.
4. 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 HomeSafe, click the WIRELESS link under ADVANCED and then
