How to see your node's SNR and current Modulation Code Scheme:

Windoze users:

You will need a 3rd party secure shell application as
Windoze does not provide.
I recommend: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
 get 'putty.exe'

Place putty.exe in your user's default working directory.
 
Using putty.exe from command prompt:
 
 
Obtain the node's LAN address at
http://localnode:8080 or
'http://[node-name].local.mesh:8080/cgi-bin/status'
Copy(1) the Node's LAN address
Click the Windoze icon on the bottom left of your desktop
enter "cmd"
type "putty root@", then paste your LAN address, then type ":2222",
then press the 'enter' key.
Enter the password for root as prompted.
 
 
Enter "while true; do iw wlan0 station dump; sleep 30; done"
 You may wish to copy and paste the above instead of typing the line.
 
When you are done watching your node's connection stats loop,
press Control+C to exit the loop.
 
Enter "exit" to terminate the terminal connection to the node.
 
(1) Windoze 101: I assume you know how to 'click and drag', 'copy and
paste',...

More_node_stats which include results of alternate MCS attempts:
 
ssh into a node
If this node links with only 1 other node:
 
Enter "while true; do cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan0/stations/"
Press 'tab' key.
Enter "rc_stats;sleep 30;done"
 
If your node links with more than one other node
'tab' will be replaced with the MAC of the other node.
Example:
while true; do cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan0/stations/68:72:51:84:96:53/rc_stats;sleep 30; done
