Firstly, the Sonos speakers have an Ethernet port. There I connected my printer and saves me so an additional repeater. The printer can be detected without any additional settings directly on the network. He is almost directly connected to the router. The router takes the Sonos network in this case, so to speak, as a virtual Ethernet cable was.
The second advantage is the usability of the Sonos-Net as WiFi. This means you can, apologize connect only with Android devices, directly to the Sonos-Net. The advantage is that this is much stronger and each loudspeaker acts as its own repeater. However, the speed is limited to 100 Mbit. Bottleneck here are the Ethernet connections of your Sonos components. Because a component has to be necessarily connected to the router yes.
Instructions for connecting with the Sonos Net:
1. Open the Sonos app
2. Settings
3. Advanced Settings
4. Connect to SonosNet
5. Allow connection
WLAN Manager you can see then whether the tablet or smartphone has connected to the Sonos-Net. Sometimes helps re looking to display to the Sonos-Net.
