SonosNet
Also known as: Sonos Mesh, Sonos Wireless
Sonos's proprietary wireless mesh network that lets speakers talk directly to each other on their own 2.4GHz radios, separate from your Wi-Fi — far more reliable than putting each speaker on Wi-Fi individually.
SonosNet is the proprietary wireless mesh that Sonos speakers use to communicate with one another. It runs on the speakers' own 2.4GHz radios, completely separate from your Wi-Fi network — so the speakers aren't competing for airtime with laptops, phones, and everything else on your wireless.
In a SonosNet setup, the speakers form a mesh among themselves, and the entire mesh reaches your network through at least one Sonos that's wired to your switch — the SonosNet root. This is the reliable way to run Sonos wirelessly.
The alternative — joining each speaker to your Wi-Fi network individually, like a phone or laptop — is consistently unreliable in practice: dropped connections, broken stereo pairs, and speakers showing a weak signal even when they're close to an access point. The fix is almost always to wire as many speakers as possible, let the rest mesh over SonosNet, and avoid giving Sonos your Wi-Fi credentials at all, which forces it into the more reliable mesh mode.
