Scanning for Mesh Nodes

This is probably a dumb question, but bear with me.

If I don't know the channel numbers and SSIDs of the nodes within range of my node, would the wifi scan reveal that information?

A WiFi scan will see nodes on
A WiFi scan will see nodes on other channels, but not other bandwidths as I understand it.  Assuming that is correct a scan at each of the bandwidths is required.

yep that makes sense
Thank you for that.  I had not thought about switching the bandwidth and re-scanning.  That makes sense.  Most of the stuff I would want to scan for will be in the 10 Mhz bandwidth area.

Wi-Fi Scans and SSIDs

Hi, Mark:
 
 In the 3.22.1.0 release, the Wi-Fi Scan columns can be sorted by clicking on the header.
To group the AREDN nodes I click 'Sig', 'Chan', 'SSID'.
All the default AREDN nodes will be grouped together, by channel, then signal strength.

 All AREDN nodes will have '-##-v3' appended to the SSID. '##' = bandwidth; 5, 10, 20.
The SSID can be edited, but the nodes with SSIDs ending in '-##-v3' will likely be the AREDN nodes.
Our local group altered the SSIDs on 2397 MHz nodes to inhibit routing on that channel and
'force' them to use DtD'ed nodes on other bands.
