Sonos Controller for Mac or PC Product Manual page 75

A-2
(If this is a wireless Sonos component, you can try moving the Sonos components closer together, or wire them temporarily
to see if the problem is related to wireless interference.)
If you are still experiencing problems, please contact the Sonos Customer Service Center.
1. Check the firewall
Firewall software installed on the computer may be blocking the ports that Sonos uses to operate. First disable all your
firewalls and try to connect again. If this resolves the problem, you should configure your firewall to work with the Sonos
Controller for Mac or PC software. If this does not resolve the problem, try step 2 below.
2. Check the router
You can bypass your router's switch to determine whether there are any router configuration issues by connecting Sonos as
shown below (note that the BRIDGE and the computer still have Internet access in this configuration):
• Be sure that your cable/DSL modem is connected to the router's WAN (Internet) port.
• Temporarily remove any other components that are wired to your network.
• Connect an Ethernet cable from the computer directly to the back of the Sonos component, and then connect another
Ethernet cable from the Sonos component directly to one of the LAN ports on your router.
• When you make a change to your network configuration, you may need to power cycle the Sonos component by
unplugging the power cord, and then plugging it back in.
• If you are not using a router, see http://faq.sonos.com/norouter.
3. Check the wiring
Check the link/activity lights on both the router and the Sonos component. The link lights should be lit solid, and the activity
lights should be blinking.
• If the link lights are not lit, try connecting to a different port.
• If the link lights still do not light, try connecting a different Ethernet cable.
When adding a controller, it doesn't detect Sonos component(s)
1. Verify that this is not a DHCP or network problem
• Disconnect the Ethernet cable from the back of the Sonos component that is wired to your router.
• Unplug the Sonos component's power cord and then plug it back in.
• When the status indicator light on the front of the Sonos component 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 doesn't recognize the Sonos component after completing this step, you can try step 2 below.
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 the instructions below).
