• Your firewall may be configured so that Sonos components cannot obtain an IP
address. If so, your ZonePlayers and Controllers will display an IP address in the
169.254.xxx.yyy range, even though there is a router/DHCP server on the net-
work. (You can check the IP addresses assigned to your ZonePlayers by selecting
Music>System Settings>About Your Digital Music System.) The DHCP serv-
er built in to some routers may be configured to supply IP addresses only to de-
vices with specific permitted Ethernet MAC addresses. If you have configured
your router in this way, you will need to grant permission to the Ethernet MAC
address of each Sonos component (including the Controller) before setting up
your system. Go to http://faq.sonos.com/dhcp for more information.

wireless channel your Sonos Digital Music System is operating on by selecting
System Settings>Advanced Settings>Wireless Channel.

System. Disconnect the Controller from the Sonos Digital Music System, and
