Utilization graph

The utilization graph shows the channel utilization for all channels in the
selected band which could indicate co-channel or adjacent channel inter-
ference. This allows you to select the best channels available in the current
environment.
If the channel view shows utilization in the wrong channels, the likely issue
is that a high energy 802.11 transmitter is very close to the OneExpert DSL.
For example, a high energy 802.11ac transmitter is using channels 149,
153, 157, and 161. The channel view should show utilization in these chan-
nels only. Move the WiFi Advisor away from the high energy transmitter and
test again.

Noise graph

The noise graph displays the noise per channel.

Channel Score

channels.
