My sonos worked seamless for 2 years. 2 weeks ago i got new evac and it woukd not connect to my wireless network so per thr requirements of both link sys and evac i had to set up a new network at 2.4 and not mixed. So i did and was able to then set up evac up. Note .. i did not make changes to the network that the sonos was originally connected just the 2.4band. I opened up my pool bar which is where my sonos is at and the speakers would not play . It kept telling me it couldn't find the network. So i deleted the app.. reinstalled ...unplugged the speaker .. opened app and connected to same network the sonos used to be connected.. still nothing . So then i set up a new system.. connected to proper network set up my play 1 1st , sonos one next , my other play 2 speakers and then my playbar. All showed they were connecting fine and thought i was all set.. well only the 1st play 1 and sonos one will play. The other 2 are not even showing as connected even though when i connect them each time it says they are all set ? Note the lights are solid white on them even after unplugging a few times when i go to connect..
