After a lot or research I bought into the music flow system rather than the Sonos system, I've been very pleased with it but I don't really know what the bridge does. It doesn't seem to create its own WiFi network like the Sonos bridge does and surely it can't extended the current wifi network because it has to be plugged into your WiFi router. Anyway the music flow system works well and I'm very pleased with it, I'm just unsure what part the bridge plays.

Have the following setup: 1 iphone 5s 1 Bridge 1 stk H3 1 stk. H5 1 dlna (nas) serverver with musiclibary Planning to expand the system if it wan't because of the following issues: The Music Flow player app is slow to sync and find the dlna libary when you go out of your wifi signal at home. Mayby taking your phone into town.. But i guess that is not that common... So you have to pair it with the server and sync it again when you get back home. If you have a large collection of music it takes like a couple of houres!!! The Music Flow player often (nearly every time) looses the speakers and the bridge as well when you also go off range of your wifi signal and you have to pair each speaker again when you get back home... Hope they get a solution to this with a newly update..

Unpack , connect the cables electric and Ethernet as supplied done no hassle no configurations and ready to go, connect any lg music flow speaker, second Ethernet spot I use it to connect a second pc on internet , I love it
