Trouble Shooting
If experiencing problems with the ASB-2, there are
some quick and easy checks, which may help to solve
these problems. If the standby button is flashing red
and white, make a note of the front LED colour. This
may help to diagnose the issue. Refer to the table on
page 28
Unable to Connect to the Wireless Network
• Check if your Wi-Fi router is Wi-Fi 802.11b/g
certified. The ASB-2 is not compatible with
N Class routers. If your Wi-Fi router is Wi-Fi
802.11n, please ensure that it is in 802.11b/g
mode. The ASB-2 is not able to talk to routers
that are 802.11n only.
• Ensure you router is DHCP enabled.
• Keep away from potential sources of interference
which may affect Wi-Fi signal, such as microwave
ovens.
• If you fail to use your PC for Wi-Fi network setup,
check whether your PC is using a Wi-Fi network.
You cannot use Ethernet connection for AirPlay
network setup.
• Make sure that the SSID name of the router
consists of alphanumeric characters, with no
space or special characters like %/#/* inserted. It
must also not be hidden.
• Check that there are enough spare IP addresses
available on your router. Some limit the number of
devices that are allowed on the network
• The ASB-2 is set to work on Channel 1 - 11. It will
not work on channels 12, 13 or 14.
No Sound/ Noisy and Crackling Sound
• Check the volume, source and play/ pause
settings.
• Check that the mains power lead is connected
to the ASB-2 and the mains power socket and is
switched on at the wall.
• If the playback is very noisy/ crackling then it may
be that the source is set to bitsream, please set
it to PCM. This is because the ASB-2 does not
decode the sound track and so needs the source
to decode it and send the individual channels to
the ASB-2.
The ASB-2 is Nonresponsive
• Check that the mains power lead is connected
to the ASB-2 and the mains power socket and is
switched on at the wall.
• Remove the power from the ASB-2, wait for the
standby LED to go out and then reconnect the
power.
• Check that it is connected to the same wireless
network as your device.
• Check you are running the latest version of
firmware. Refer to page 15.
Occasional Breaking up of AirPlay Music
Playback
• Move the ASB-2 closer to your Wi-Fi router.
• Avoid using Wi-Fi channel which is overlapped by
the nearby Wi-Fi network.
• Check if your network speed is fast enough (in
cases where multiple devices share the same
router, the AirPlay performance may be affected).
Turn off the other devices connected to your router.
• Enable the Quality of Service (QoS) option (if
available on the Wi-Fi router).
• Turn off other Wi-Fi routers or range extenders to
try to diagnose a possible faulty one.
No AirPlay Icon on my iTunes Host Device
• Make sure the ASB-2 is connected to the same
Wi-Fi network as the host device
• It can sometimes take up to 30 seconds for the
ASB-2 to appear on the network. Try leaving
iTunes for a bit to see if it appears.
AirPlay Connection Failed with Mac or PC
• Temporarily disable the firewall and security
software to see whether it blocks the ports that
AirPlay uses to stream content. Refer to the help
documentation for your router/ firewall/ network
security to unblock the ports used by AirPlay.
• When you use iPod Touch/iPhone/iPad/Mac/PC
for AirPlay, if the music play breaks or stops, try
to restart your iPod Touch/iPhone/iPad, iTunes or
ASB-2.
• Video streaming or FTP downloads may overload
your router and therefore may cause interruptions
during AirPlay music play. Try to reduce the load
of your router.
If still experiencing difficulties after making the
suggested checks, please call the help desk for further
assistance. The help desk is open from 9.00am
to 5.00pm (GMT), Monday to Friday (excluding Bank
Holidays) and can be contacted on [phone].

from.
