Help using the 'scan'

Hi guys,

I’m trying to use the ‘scan’ functionality to determinate the best channel and configuration for my APs but I’m not sure how should I read it.
I understand that I should select the channel with less APs but not sure how the ‘Signal Strength’ and ‘Noise Floor’ should be considered, should I use the channel with less APs and less noise? In this example, what should I do?
Thanks!!

its better to use snooper because it shows channel utilization

example

channel 1: 10 other networks on it but 10% utilization

is better than

channel 6: only 1 other network on it but 50% utilization

Ok, and what about the noise floor? Can I ignore it to select the channel?

The spectral scan is better over all above mentioned options. Snooper could be taken as fast approximate overview of an situation in the air. Finally you should measure on clients side also.
