Sorry for the delay. Anyway, I think it would be better to make this
configurable or smarter instead of a random channel selection. I just
checked what iwd is doing and if I got it right, the iwd daemon does the
channel selection itself.

Random channel selection is a bit a wild solution :).

This is what I would suggest. Alternatively, can't we use some metrics
from the last scan to figure out which channel is crowded?

Generally I would like to avoid adding more config option if there is a
way to figure it out.
