Firmware
The WLAN controller can store AP’s firmware in its’ built-in memory. Under the
Firmware
tab page
administrator can upload new AP firmware to the WLAN controller’s memory allowing for easy remote AP
upgrade and restore operations from the AP
List
page. The AP firmware listed under this page can be
downloaded or deleted from WLAN controller memory if desired.
8.7 Rogue AP Detection
Rogue AP detection is another essential way of protecting your network environment. Wide AP
Management supports the detection of non-authorized access points present in the vicinity. Non-
authorized access points pose a possible problem in terms of wireless interference.
General Configuration
Rogue AP Detection
: to enable or disable the feature, if enabled, the system may take another effort to
detect them.
Scanning Interval
: to determine the scanning period
Channel Switching
: AP will scan all channels and choose the one with the least utilization rate
Sensor List
: to select RF cards (only selected AP models) for the scanning job as sensor. The AP will
broadcast probe requests to collect surrounding APs' information. It is able to check the scanning log by
clicking the hyperlink of “View”
Trust APs
: to add AP’s shown in the suspected rogue AP list to the trusted list for further management if it
can be manually identified as a safe source.
Rogue AP List
Discovered access points are temporarily put in the Rogue AP list. Click one of the hyperlinked BSSID’s to
see its detailed information. However, if admin recognized some of the listed APs as trusted, just check
the checkboxes before the BSSID column and then click
Add to Trusted AP List.
This action will be recorded
in the
Trusted AP Configuration.
8.8 AP Load Balancing
This is a function that prevents managed APs from overloading. When the system detects the occurrence
of APs' associated-client numbers exceeding a predefined threshold at circumstances and other APs in the
same group are still below the threshold, the balancing function will be activated to decrease the
overloading APs' transmit power and increase other available APs' transmit power; this will let other
available APs have more chance to be associated. The system can divide the managed APs into groups;
define the group threshold, and a time interval which will trigger the AP load balancing.
Load Balancing
: to enable or disable the feature
AP Distance:
This parameter allows the administrator to specify the distance which will be used as a
