When adding the handheld Sonos Controller, it fails to detect the
ZonePlayer(s)
Wireless interference or a network problem may be preventing the Controller from
joining your Sonos Multi-Room Music System.
Verify that this is not a DHCP or network problem
1.
• Disconnect the Ethernet cable from the back of the ZonePlayer (or ZoneBridge
if you purchased one separately) so that it is not connected to your network.
• Unplug the ZonePlayer's power cord and then plug it back in.
• When the status indicator light on the front of the ZonePlayer stops blinking
white, try adding your Controller again.
If this 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 ZonePlayer after completing this step,
you can try step 2 below.
Turn off any 2.4GHz cordless phones
2.
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.)
Put 108 Mbps wireless routers into 54 Mbps mode
3.
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 wireless network will become sluggish.
