Discovering Networks and Access Points
11
Yellow closed lock: One or more access points use
WEP or Cisco LEAP security protocol. These are less
secure than other protocols.
Green closed lock: All access points use security
protocols that are more secure than WEP, for example,
WPA or WPA2.
Gray closed lock: Access points on this network are
using multiple security protocols.
 Access Points #: The number displayed next to the
icon is the number of access points near
your location.
 Filter Button: Tap this field to add a filter for specific
network characteristics, such as SSID string, minimum
signal strength, or 802.11 media type.
NOTE: You can
set only one filter at a time. Once a filter is
set, the Networks list screen re-opens. The title of the
screen changes to “Networks (X of Y)”, such that
X = the number of networks filtered, and
Y = the total number of networks discovered.
This icon appears to the right of the active filter. Tap
the icon to remove the filter.
Tap the Help button on the Filter Networks By:
screen for more detail about each option.
 SNR: Signal-to-Noise Ratio, a measure of signal strength
relative to noise. The ratio is measured in decibels (dB).
NOTE: For networks, the SNR of the strongest AP in the
network is displayed.
This is also a variable field, which changes based on the
So
rt option currently applied. For example, if the list is
sorted by Client Count, the number of clients connected
to the network appears in this space on the screen (as
shown in Figure 5).
For Networks, this space can also show the 802.11 Type,
Band, or time since the network was Last Seen.
