Under normal circumstances the WLAN client would only log onto another
access point if the connection to the access point used up to that point was
lost completely (hard roaming). Soft roaming on the other hand enables the
client to use scan information to roam to the strongest access point. With the
background scanning function, the LANCOM Wireless Router in client mode
can gather information on other available access points prior to the connec-
tion being lost. In this case the client is not switched to another access point
once the existing connection has been lost completely, but rather when
another access point within its range has a stronger signal.
To enable soft roaming in WEBconfig or telnet, change to Setup > Inter-

Enable soft roaming and, if required, set the other parameters (such as
threshold levels and signal level).
To configure background scanning in LANconfig, go to the 'Radio' tab
under the physical WLAN settings for the desired WLAN interface.
Enter the background scan interval as the time in which the LANCOM
Wireless Router cyclically searches the currently unused frequencies of the
