5.1.2 Wireless Networks (VSS)
If you are operating your device in Access Point Mode ( Wireless LAN->WLAN->Radio
Settings->
->Operation Mode =
#
), in the menu Wireless
LAN->WLAN->Wireless Networks (VSS)->
/ New you can edit the wireless networks
required or set new ones up.
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
and read by any attacker with the appropriate resources. Particular attention must therefore
be paid to protecting the wireless connection.
The security modes WPA-PSK and WPA Enterprise are available. WPA Enterprise offers
the highest level of security, but this security mode is geared at enterprises, because it re-
quires a central authentication server. Private users should choose choose WPA-PSK with
only WPA2 and AES for optimal security, as well as assign a secure at least 8-digit WLAN
password.
