I’ve not used Sonos before, but have bought 4 speakers for 4 points in my hotel & restaurant. I couldn’t connect to any of the speakers via our internal WiFi system (it’s not like your standard broadband).
Normally the WiFi signal is very good, any device can connect to it.
The speakers weren’t connecting at all, so we bought a sonos boost. I connected the boost into the router & it picked up a speaker right next to it, and I successfully used the speaker.
However, the sonos boost still doesn’t seem to help enough to get the speaker working when I’m in a different room.
Any help with what I could try next would be gratefully received! It should be noted I’m only trying to connect 4 speakers all on the ground floor of the hotel, in the bar & restaurant.
