4.9 Tools
4.9.1 Site Survey
The Site Survey test shows overview information for wireless networks in a local geographic
area. Using this test, an administrator can scan for working access points, check their operating
channels, encryption and see signal/noise levels. An administrator can use this feature to identify a clear
channel to set the device.
Note: Note that Site Survey function can take several minutes to perform.
A Site Survey test is performed every time on the startup of the device, therefore the results of
the last performed Site Survey test and its time can be found on the page. Thus, to obtain the results,
the initiation of the scan is not necessary. To perform the Site Survey test currently, click the Scan
button:
