In setting it up though, I was completely shocked to find it wouldn’t connect to my 5GHZ network. I’ve streamed music using AirPlay for many years and when I jumped to 5GHz, stability improved dramatically, so I never used 2.4Ghz again (except for wireless printing). For example, the large multi-suite home I’m in now is packed next to other similar homes and thus the 2.4Ghz spectrum is over saturated making reliable streaming (let alone reliable Internet usage) on it pretty much useless. For this reason, I hardwired the Sonos Beam to my router instead of even trying to use it wirelessly.
Can someone please explain the logic of this?
I mean 2.4GHz does give you an extended range but if the stability is flaky, what good is the extended range? I would have at least thought it would support all ranges, thus letting you connect to the band that is optimal for you (since most people have dual bands on their router).
Alternatively is there something special about Sonos networking system that makes it perform better or maybe cache better upon the 2.4Ghz band to maintain a stable music stream?
For example, I haven’t even tried streaming with Airplay 2 yet, so perhaps that creates a better cached stream that is more stable on the 2.4Ghz band as well. Anyone have any experiences comparing Airplay 2 stability to Airplay 1?
All said and done, the idea was to add more Sonos speakers to other rooms which would require wireless networking to do so. So if we buy them and they can’t maintain a stable stream, we’ll return them and forget about creating a whole Sonos system which was our desire in the first place.

2) 2.4 GHz offers better penetrations and range, albeit at less speed and throughput.
3) Sonos was originally designed to use Sonosnet, a dedicated proprietary mesh network designed for streaming. It puts your system on a 2.4 GHz channel separate from your home WiFI, and it's a mesh for greater reliability. If you intend to expand beyond 2-3 devices, I recommend switching to Sonosnet (aka Wired Setup).
