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 page 25 for help with this step.)
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.
Change the wireless channel your Sonos system is operating on.

You can follow the steps below to change the wireless channel.
