Detecting Interferers; The Interferer Events List Screen - Netscout AirCheck G2 User Manual

D
VII. ETECTING
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, touch the
Interferers row on the Home Screen.
NOTES:
 To collect interferer information more quickly, go to
Settings > Interferer Settings, and enable only
one band, which decreases the number of monitored
channels.
 You can also turn On the Interferers Only Scan option
to cause the AirCheck G2 to look ONLY for interfering
devices. 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, touch the Filter button
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.
Touch the Sort 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
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
16)
sequential order, based on the selected Sort option and
Inaudible Interferers settings (in Settings > Interferer
Settings).
