Wireless (WLAN Interface) – Chapter 7
The parameters of this function are:
Since the interruption of the WLAN connection often occurs directly after changing
the AP, the ping interval is set to 0.5 seconds for a short time in this situation. As soon
as the first response is received correctly, the ping interval returns to the set value.
This ensures that such a connection termination is detected quickly and can be cor
-
rected promptly with a
Wireless Reconnect
if necessary.

. The access points are identified with the MAC address of the BSSID.
The
Prefer
function makes sense if the radio modem always moves along a fixed
course and in an environment with many APs. Then it may be advantageous if only
certain APs should be used to run this course with as few roamings as possible.
The
Avoid
mode can be useful if access points are received good for some time, but
are quickly hidden during movement. Putting these APs to the Avoid-List can lead to
better roaming decisions.
The
Avoid from List
function does not completely prevent a connection with the list
-
ed APs. If no other suitable AP is available, the WLAN driver of the HG G
will still try to establish a connection.
Strictly avoid
ensures that the radio modem does not connect to the listed APs even
if no other suitable APs are available.
