I had a weird one the other day when replacing a couple of dead Connects in a pool house. One of the new connects was very aggressive trying to connect using the wireless even though I had a wired connection plugged in and the nearest existing Sonos box was a good 100ft away in the main house. Brought the network to a dead stop. I thought I had a bad connect until I set it up via wireless and then put it on a wire and turned off the radio.
