Troubleshooting
Problem
Unable to play the Internet radio.
Firmware update failed.
The unit is unable to connect to the
Internet via a wireless LAN router
(access point).
MusicCast CONTROLLER does not
detect a wireless network.
The iPhone does not detect the unit
when using AirPlay.
Cause
The selected Internet radio station is currently out of service.
The selected Internet radio station is currently broadcasting
silence.
Access to the network is restricted by the firewall settings of
the network devices (such as the router).
The network connection is unstable.
The wireless LAN router is turned off.
The unit and the wireless LAN router are too far apart.
There is an obstacle between the unit and the wireless LAN
router.
A device that uses a frequency band of 2.4 GHz (microwave
oven, wireless LAN device, etc.) is interfering the wireless
communication.
Access to the network is restricted by the firewall settings of
the wireless LAN router (access point).
You are using a router supporting multi SSIDs.
There may be a network problem at the radio station, or the
broadcasting service may have been stopped. Try to play the
station later or select another station.
Some Internet radio stations broadcast silence at certain
times of the day. In this case, there is no problem with the
reception, but no audio will be produced. Try the station later
or select another station.
Check the firewall settings on your devices. The Internet radio
can be played only through the port designated by each
radio station. The port number varies depending on the radio
station.
Try updating again after a while.
Turn on the power to the wireless LAN router.
Place the unit and the wireless LAN router closer to each
other.
Move the unit and the wireless LAN router in a location where
there are no obstacles between them.
Turn off the power to the device, or relocate it further away
from the unit and the wireless LAN router.
Check the firewall setting of the wireless LAN router.
The router's network split function may be blocking access to
the unit. If you are connecting an iPhone, use an SSID that
allows access to the unit. (Try to connect to the Primary SSID.)
