HP Pavilion 501, Configuration And Administration Manual

32 Wireless configuration
The HP 501 regularly performs scans to detects beacon frames sent by APs within range. These
are referred to as passive scans. When the HP 501 is not associated with an AP, the duration of
the passive scan is lengthened to more quickly build the available AP list. To display the latest
detected APs, click
Refresh .
You can click Clear All to remove all APs from the list. This button is disabled when the radio
is disabled.
You can click Start Scan to initiate an active scan. An active scan sends probe requests to
detect nearby APs rather than passively wait to receive beacons from them. Therefore, the
active scan may populate the AP list more quickly. The scan is performed on all available
channels in the frequency band currently in use. If the radio mode is Auto, both the 2.4 GHz
and 5 GHz frequency bands are scanned. The active scan does not send probes to channels
that are reserved due to regulations in the selected country of operation.
The HP 501 sends two probes on each channel and collects the responses. It does not attempt
to associate with another AP in this scan—the scan only collects data for display. Information
for existing APs in the list is updated, and newly discovered APs are added to the bottom of the
list. A single scan may not find all available APs. If you suspect additional APs are available,
perform another scan.
Notice
If the HP 501 is currently associated with an AP, the scan disrupts the connection for up to
about 8 seconds, depending on how many channels are scanned (which varies by country and
radio mode).
If a scan is initiated while the HP 501 is in the process of associating with an AP, or while it is
roaming to associate with another AP, the scan request may be ignored. To avoid interfering
with association attempts in progress,
Start Scan is disabled when the radio is disabled and
when work group bridge mode is enabled and in the disconnected state.
Privacy Indicates whether there is any security enabled on the
neighboring AP.
•
Off indicates that no security is enabled on the AP.
•
On indicates that the neighboring device has some
security in place.
WPA
Indicates whether WPA security is on or off for this AP.
Mode Indicates the operating mode of the AP: 802.11a, b, g, n, or
ac, or a combination of modes.
Channel The channel the AP is operating on.
Rate The rate in megabits per second at which the AP is currently
beaconing.
Signal
A bar chart indicating the signal strength.
