• Disconnect the Ethernet cables from the back of the Sonos component so that it is not connected to your network.
• Unplug the Sonos component's power cord and then plug it back in.
• Once the status indicator light stops blinking white, try adding your controller again.
If it works, your router's DHCP server may have run out of available IP addresses to assign to the controller. In most cases you
can log into your router by typing http://192.168.1.1 into your browser’s address line (the IP address of your router may be
different). Check the DHCP settings and increase the number of IP addresses available in the DHCP scope.
If your controller still does not recognize the Sonos component after completing this step, you can try step 2.
2.
Turn off any 2.4GHz cordless phones.
Some 2.4GHz cordless telephones can cause wireless interference. If turning off your 2.4GHz cordless phone resolves the
problem, you should consider switching to a 5.8Ghz or 900Mhz phone (or change the wireless channel your Sonos system is
operating on - see step 4 below.)
3.
Put 108 Mbps wireless routers into 54 Mbps mode.
Sonos cannot function properly when a router is operating in turbo mode. In order to double the speed from 54 Mbps to 108
Mbps, the router goes into a wide bandwidth mode which utilizes most of the 2.4 GHz spectrum that the FCC has set aside for
802.11b/g devices. This means that interference (RF noise) will occur with any other 2.4 GHz device that is not operating on
the same channel as the 108 Mbps device (usually channel 6). While it is possible to put all of your wireless devices on
channel 6, it is unwise. The devices will have to compete for available bandwidth, and your entire Wi-Fi network will become
sluggish and bogged down.
4.
Change the wireless channel your Sonos system is operating on.
• Using the Desktop Controller software for Windows: From the File menu, select Preferences. Click the Advanced tab,
and then select another wireless channel from the Wireless Channel list.
• Using the Desktop Controller software for Macintosh: From the Sonos menu, select Preferences. Click the Advanced
tab, and then select another wireless channel from the Wireless Channel list.
It may take several seconds for the switch to take effect. If you have music playing, a short music dropout will occur during
the wireless channel change.
