Work Group Mode A Workgroup Bridge (WGB) can provide a wireless
infrastructure connection for Ethernet−enabled devices. Devices that do not have a
wireless client adapter in order to connect to the wireless network can be connected to
the WGB through the Ethernet port. The WGB associates to the root AP through the

Q. How does roaming work? Who roams when there is not enough signal
strength, the client or the AP?
strength, the client or the AP?
A. Roaming is an algorithm implemented and controlled by the client adapter and it is not
defined by IEEE standards. The roaming functionality is based on signal quality, not just the
proximity to the AP. Each vendor has their own logic to implement roaming. For Cisco
clients, roaming is caused by one of these events:
defined by IEEE standards. The roaming functionality is based on signal quality, not just the
proximity to the AP. Each vendor has their own logic to implement roaming. For Cisco
clients, roaming is caused by one of these events:
Maximum data retry count is exceeded
♦
Missed too many beacons

Data rate shift
♦
Initial startup
♦
Periodic client interval (if configured)

Q. What is fast roaming?
A. Fast roaming is a feature where the client's credentials are not sent to the Authentication
server every time the client authenticates. Once a client authenticates to an AAA server,
credentials are cached in the AP. The next time a client roams, the AP authenticates and
supplies the credentials by itself to the client without sending it back to the AAA server. This
saves time and enables faster roams of clients. For more information on fast roaming, refer to
the Understanding Fast Secure Roaming section of Configuring WDS, Fast Secure Roaming,
and Radio Management.
