I recently added a Netgear Range extender to a room that was having trouble getting a strong wifi signal but not for Sonos use. I have a Bridge and a mix of 7 different Sonos Components. Now, I keep getting a message that "Some Sonos players are using the wireless connection from your range extender device. You will be unable to play music in a group of rooms including such a player. To ensure playback in all grouped rooms, you will need a Boost or a player permanently wired to your router." I have a Bridge hardwired to my router. I don't know how a device connected to the extender and I can't figure out which one it is. I have even unplugged the extender and I'm still getting the message. I have been able to play all of my units in groups but I'm getting some occasional drop out. Today, everything is working well but I keep getting the message anytime I change groupings. Any suggestions?
