I recieved an email from Sonos telling me to get a boost as Bridges were outdated. I then read the instructions about removing the bridge but this was only if the bridge or bridges were wired in (ethernet) mine are not (so now not sure if they were doing anything atll! I have set up the boost and I also have several other devices some wired some wireless and not sure how to check if I have the optimum set up? or what is actually doing anything?!?!
