Hello
I’d to trigger the wifi optimization button, but via a cronjob. What command can I use for that (excl. scheduling)?

You can switch WIFI on and off with the following command

wifi down
wifi off

But that doesn’t trigger the channel optimization, does it?
Background is; apparently my wifi space is over crowded, sometimes 1 is better, sometimes 11!
I tested the solution manually over a couple of weeks and it works, so I’d like to automate it every X hours…
