I NFLUENCE OF THE E XTENDED R OAMING P ARAMETERS
The Extended Roaming Parameters are configured under „Configuration  Adv. WLAN
 Roaming WLAN-1“.
Neighbour Roaming is deactivated in the Seamless Roaming mode. The two other roaming
parameters can be applied.
The scanning process of the two interfaces can be shortened via the Restricted Channel
List. The two boxes „SNR Roaming Threshold“ and „Packet Number below
Threshold“ can be used to identify worsening connections. Here however it must be
considered that the parameters only refer to the passive interfaces so that the active data
connection is not adversely affected.

In addition to the known status messages, other seamless roaming specific messages are
displayed in the Event log. If a “better” connection is found, the message „Switch from
WLAN-1 to WLAN-2“ appears. Further, the interface searching for better connections
permanently produces status messages and WPA messages, if any. This is no
malfunction.
On the WLAN diagnosis page is displayed whether the interface is just transferring data
(seamless roaming status active) or whether the interface is searching for better
connections (passive). The scan results of both interfaces may be different since it has to
be prevented that the two interfaces select the same Access Point. Therefore it is possible
that the passive interface does not see the Access Point of the active one and vice versa.
