Field Description
Fragmentation
Threshold
Enter the maximum size as of which the data packets are to be
fragmented (i.e. split into smaller units). Low values are recom-
mended for this field in areas with poor reception and in the
event of radio interference.
Possible values are  to ('.
The default value is (' bytes.
10.1.2 Wireless Networks (VSS)

WPA Cipher as well as WPA2 Cipher = "  /$6!
The Preshared Key is filled with an internal system value, which you must change
during configuration.
Setting network names
In contrast to a LAN set up over Ethernet, a wireless LAN does not have any cables for set-
ting up a permanent connection between the server and clients. Access violations or faults
may therefore occur with directly adjacent radio networks. To prevent this, every radio net-
work has a parameter that uniquely identifies the network and is comparable with a domain
name. Only clients with a network configuration that matches that of your device can com-
municate in this WLAN. The corresponding parameter is called the network name. In the
network environment, it is sometimes also referred to as the SSID.
Protection of wireless networks
As data can be transmitted over the air in the WLAN, this data can in theory be intercepted
