NB2800
User Manual for NRSW version 4.5.0.100
Prior to setting up an access point, it is always a good idea to run a network scan for getting a list
of neighboring WLAN networks and then choose the less interfering channel. Please note that two
adequate channels are required for getting good throughputs with 802.11n and a bandwidth of 40
MHz.
WLAN Configuration
Running in client mode, it is possible to connect to one ore more remote access-points. The system
will switch to the next network in the list in case one goes down and return to the highest-prioritized
network as soon as it comes back. You can perform a WLAN network scan and pick the settings from
the discovered information directly. The authentication credentials have to be obtained by the operator
of the remote access point.
Parameter WLAN Client Configuration
SSID The network name (called SSID)
Security mode The desired security mode
WPA/WPA2 mixed mode WPA2 should be preferred over WPA1, running WPA/WPA2 mixed-
mode offers both.
WPA cipher The WPA cipher to be used, the default is to run both (TKIP and
CCMP)
Identity The identity used for WPA-RADIUS and WPA-EAP-TLS
Passphrase The passphrase used for authentication with WPA-PSK, otherwise the
key passphrase for WPA-EAP-TLS
Force PMF Enables Protected Management Frames
Enable fast transition If client, enable fast roaming capabilites via FT. FT is only performed
if the AP supports this feature, too
Required signal strength Required signal strength to esablish the connection
The client is performing background scans for the purpose of roaming within an ESS. The back-
ground scans are based on the current signal strenght.
Parameter WLAN Client Background Scan Parameters
Threshold The signal strength threshold in dBm when the long or short time
interval should occur
Long interval The time in seconds when a background scan should be performed if
the threshold is above the given threshold value
Short interval The time in seconds when a background scan should be performed if
the threshold is below the given threshold value
