2. Choose another channel from the list.
It may take several seconds for the switch to take effect. If you have music playing, a short music dropout may occur during
the wireless channel change.
Reset the SONOS CONTROL
If the SONOS CONTROL’s screen should ever become unresponsive, you can remove the battery from the back of the unit, and
then immediately put it back in. Place the CONTROL into the charging cradle for a few moments to wake it up.
Restart the SONOS CONTROL
There may be an occasion when you need to renew your DHCP lease (get a new IP address from your Internet provider's DHCP
server.) If this occurs, you can restart your CONTROL by selecting CONTROL Settings -> Advanced Settings -> Restart
Controller from the Settings menu.
Can’t add the SONOS CONTROL to your Sonos system
1. 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 "The SONOS CONTROL is acting sluggish, or not all rooms are visible" on page 29 for help with this step.)
2. Put 108 Mbps wireless routers into 54 Mbps mode.
Sonos cannot function properly when a router is operating in turbo mode. To double the speed from 54 Mbps to 108 Mbps,
the router goes into a wide bandwidth mode which uses 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 wireless network will
become sluggish.
3. Change the wireless channel your Sonos system is operating on.
