8. Appendix
a) Known issues
1. Wired connection (LAN)
As you may already know from other wired network devices,
establishing a link essentially just involves plugging in the cable. Please
ensure that a sound physical connection is present
(left LED lit

. If that is the case and a connection is still not available, then
the problem will be either the settings of your gateway (the computer in your network that
manages the connection to the Internet) or those of your router. As is often the case in
life, it helps to be on good terms with your favorite administrator.
2. No radio link between the server and ALLSOUND III
Troubleshooting may prove somewhat more involved in this case, and so we would like to
refer you to the detailed manual for further information. Here is a brief checklist as initial
assistance:
Is the music server running correctly?
Are all of the configuration files correct and does the server appear in the
Processes list (CTRL + SHIFT+ ESC)? If it is not listed, check your server-side
configuration.
Is there a conflict with your filter or firewall rules?
The firewall can be disabled completely as an extreme measure when running
Windows, or its functionality should not be extended to cover the ALLSOUND III.
Disabling it briefly for the test can be useful when hunting down the problem.
Is any form of communication with the ALLSOUND III possible?
A ping to the ALLSOUND III's IP address as described above will clarify this
question. If the ALLSOUND III doesn't respond to your ping, it certainly won't be
able to communicate via UPnP. If you are not successful here, then you have a
different network problem which can range from a typo in the encryption key to
massive configuration errors.
3. The connection fails after several minutes
This points toward one of the small peculiarities of the UPnP standard. The useful
communication begins on one of 1024 ports and changes regularly during operation. Not
all firewall applications recognize this knocking on various doors as a continuous
connection. Depending on its configuration, the firewall may decide not to ask the
unknown visitor in.
Depending on the firewall application, the following actions will solve the problem:
•
Specifying the ALLSOUND III (with a static IP) as a so-called trusted host, i.e. a
device whose communication is guaranteed not to be malicious.
•
Allow the server to communicate with the ALLSOUND III on ports 1024-65535.
•
Activate an exception for “UPnP Framework” in the Windows XP firewall, or set other
firewalls to allow UPnP communication.
