Detecting Interferers
32
7. DETECTING INTERFERERS
As the AirCheck G2 scans through your local wireless
channels, it also observes and records devices that might be
causing interference, such as a microwave oven, wireless
mouse, or Bluetooth device. Interference from non-802.11
devices can negatively impact your network performance.
When a potential interfering device is detected, AirCheck G2
populates the Interferer Events screen with data about the
interferer. To see these interferer events, tap the Interferers
row on the Home Screen.
NOTES:
• To collect interferer information more quickly, go to
Settings > I
nterferer Settings, and enable only
one band, which decreases the number of monitored
channels.
• You can also turn On th
e Interferers Only Scan option
to cause the AirCheck G2 to look ONLY for interfering
devices. The AirCheck G2 will not discover or display
Networks, APs, Clients, or Channel utilization while the
Interferers Only Scan is On.
• To view a list of all the interferer types AirCheck G2 can
display if detected, t
ap the Filter button (Figure 17)
and then the Type field.
The Interferer Events List Screen
The Interferer Events screen lists the interference events that
have been detected in your environment. It shows the
following information for each of the interferers:
Interferer Events (#): The numeric value in parentheses
indicates the number of interference sources that have
been observed as active during the last 30 seconds.
Sort (Option Field): This field shows the sort option that
is currently applied. The default sort option is Event ID.
Tap the So
rt field to change the order in which
interferers are listed. The value by which the list is sorted
shows prominently for each interferer. For example, if
you change to Sort by Channels Impacted, the Events
list screen displays the impacted channel number range
next to each interferer, instead of the Band it is
operating on, as shown in Figure 17.
Sort Order Button: These arrows switch the list
order from ascending to descending, and vice versa.
Event (#): Numbers the interferer events in order of
occurrence. NOTE: Events may or may not be listed in
sequential order, based on the selected Sort option and
Inaudible Interferers settings (in Settings > Interferer
Settings).
