(it does mention a frequency hopping physical layer but that was part of the obsolete predecessor from 1997, the modern spec uses OFDM so unless all your equipment is from the last century you're not using frequency hopping)
I think there is a misunderstanding related to the terms here:
1. IIRC my router is supposed to switch channel (i.e. frequency) automatically unless I explicitly set it to a fixed channel.
I don't know how but my devices figures out and continues working.
2. I think the misunderstanding is related to the word frequency hopping or whatever was used further up in the discussion.
I normally take "frequency hopping" to mean changing frequncy multiple times a minute or even faster while I doubt my wireless access point will switch channels more than a few times in 24 hours.
Disclaimer: I never really sat down and verified if it ever changed.
Also agree with logicalle that I wish for a bit more civility.
Based on my frequent lurking, I would guess it was due to the personal (and off topic) nature of the comment. Addressing users specifically in this way seems to be looked down upon here.
