5Ghz is only used in a 5.1 set up I suppose? In terms of connectivity bond, projecting sound from Tv (Movies)
2.4Ghz is employed in multi-room usage? In terms of projecting your movie audio to different rooms; Streaming music from Spotify (I believe that a 5.1 streaming music is using 2.4ghz then)
So how Sonosnet have anything to do with this?
If I'm using a standard set up for my 5.1, I'm actually getting my router to work on 5ghz? if this statement even make sense

Basically, 5ghz is going to be used for communication between speakers setup in the 5.1 room you've setup. So your Sonos soudbar, Sub, and satellite surround speakers will be communicating over 5gHz. All other communication will be over 2.4ghz.
Sonosnet (now called 'wired') is basically Sonos own 2.4ghz wireless network, separate from the wifi network your router creates. When you're in standard (now called 'wireless') you're using your routers 2.4ghz wifi. Sonos will never use your router's 5ghz wifi.
This article does a pretty good job of explaining things.
