I recently removed the LAN wire from my Beam and setup my Sonos system to use wireless instead due to lack of available connections on my router. Now every time I group speakers I get the often reported wireless range extender error message. I do not have a wireless range extender.
My system: Beam x 1 | One (V1) x2 | Play:1 x 4 pair | Play: 3 x1
