Scanning for Access Points (client mode only)
While the client is connected to an access point, it scans for other access points in
the background with which it can connect when necessary. There are three modes
for scanning access points that can be selected in the Background scan mode list
box.
If you set Disable, there is no scan for access points while the client is connected.
If you set Scan if Idle, there is a scan for access points when no data transfer takes
place for a certain time.
If you set Scan Always, access points are scanned continuously.
The Background scan interval parameter specifies the interval at which further
access points are scanned.
To optimize the scanning for further access points, you can specify channels for
the client on which other access points can be found. To allow this, the Background
Scan Ch.Select check box must be set and the channels of the other access point
are entered in the Background Scan Channels text box. Enter the channels
separated by blanks.
If the client finds a better access point, it attempts to connect to it. Before it
changes, the new access point must be better than the current access point by a
certain value. The threshold at which the client changes to the new access point
can be specified with the Roaming threshold parameter.
