Question: Is the bridge's range dependent on the range of my multiple access point wifi network or does it have its own range/network? How far?
Document: Works fine. Hooks to router as the Internet access point for system, and provides the Sono's specific WiFi network (independent of my house Wifi). Range is sufficient to place my Sono's Play 1/3's anywhere in large house and backyard. (about 50-60'',through walls etc)
You need 1 Sonos component to be plugged in to your home network (any of the PLAY speakers, Soundbar, Bridge, etc.) So, as an example, you must plug in either the BRIDGE or the PLAY:1 to your network with a network cable. This turns that component into a wireless access point (or as consumers tend to call it, a "Wifi router".) All other Sonos components will now be able to wirelessly talk to that plugged-in device.
I initially bought this because my router and my stereo were on opposite sides of my living room. It worked great and didn't take up much room at all. After I moved, I was able to attach one of the ZonePlayers directly to the stereo, and I discovered I could use the ZoneBridge as an access point to provide wired ethernet ports at the other end of my house from my wireless router. I have a wired network printer that I can now put anywhere I want and use over the wireless network.
Should a component in your house be too far away (say, your garage) from the plugged-in one, you can connect it to your network via cable, if available, or set up a Sonos BRIDGE (or any other Sonos speaker) wirelessly somewhere between the plugged-in one and the Garage speaker. The BRIDGE or other speaker strengthens the wireless from the plugged-in one, and extends the range to the one in the Garage.
Honestly -- I somewhat regret getting the Play 5. I think I would have rather gotten three more Play 1s instead. The Play 1 is really not that far off from the 5 when it comes to listening enjoyment. I know audiophiles will sniff at that -- really my goal is just to fill my house with sound.The ONLY downside I can see to the Sonos system at all is that it doesn't play Itunes Radio. Maybe at some point? ?
My Apple AirPort Extreme Base Station is centrally located in my house. The PC that stores all my music was at the far end of the house. Before the ZoneBridge 100 (BR100) I had to "waste" a ZonePlayer 80, a $350 investment. Now I have the BR100 connected directly to the Base Station. It simply sits on top of the Base Station, with no noticeable impact on range or wireless performance.
Had immense issues getting Sonos bridge and speakers to work on our home wifi, tried to reach out for some support, but never got reply. Took a chance and bought a new powerful wifi router and after a difficult installation phase where sonos bridge never connected until many resets of router and bridge it finally worked...Since then it's been working on all devices so interoperability with wifi routers are apparently a weak point with Sonos and should be noted, even if the faults are on the router side.
Purchased to work with the Play 1 so that I could put the Play 1 anywhere in my living room.Have this located by my wireless router in my office, a little away from the Play 1 but have no problem streaming - clearly has good range. It is very easy to set up - 'set it and forget it' type operation.It's small, clean looking ad complements my (much larger) Apple WiFi / time capsule.Can't find anything wrong with it - met all my expectations.
The Sonos Bridge allowed me to put speakers in areas where I don't have wired network access. It was incredibly easy to setup - just plug it in.
My Sonos system consisted of a Bridge and 2 Connects. My music library is encoded in FLACC.The home network environment is multiple Windows 7 and 8 machines on a WNDR4500 Netgear router connected to a DSL modem with a 5.2 Mbps Internet connection.The problem with the Sonos controller is that it stops sending the audio to the speakers when playing music or internet radio. The controller thinks it is still playing but there is no sound from the speakers.
Answer: No, Sonos does NOT use your wifi network at all. It plugs into your wired Internet connection at your router, and creates its own wireless network, which is proprietary and not standard Wifi. In fact, that is the entire job of the Bridge. Sonos wireless network is a mesh, meaning all sonos devices in the network can relay signals. So the more sonos, the better the network, the better the range of coverage.
