D - 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. 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. The description of the network port on page 9 already
brought up this topic, but please also see "For deeper understanding: about routers, SSID, MAC & IPs "
on page 16 for more information. As is often the case in life, it helps to be on good terms with your favour-
ite administrator. Heartfelt thanks and a charming smile often goes a long way.
2. No radio link between the server and NOXON
The fact that an MC broadcast is used for the first connection attempt between the client and server makes
this initial connection relatively vulnerable. Depending on the network adapter, the MC range is often not
routed at all in the network, especially when using wireless adapters. A number of local packet filters (such
as firewall programs) see this form of communication as an attack on the system and thus filter it. Most
better-quality firewall programs initially reject these broadcasts, but can be set up to permit unrestricted
communication by entering the NOXON as a so-called trusted host.
The Windows firewall, for example, offers exceptions for a variety of protocols and technologies, and the
default option "Universal Plug and Play" in the advanced settings allows unrestricted traffic for UPnP ser-
vices.
If this option is not available, disable local packet filtering for the NOXON's IP address. In this case it's of
course advisable to assign a fixed IP address to the NOXON to ensure that the rule does not need to be
edited continually. You should also perform a check to determine whether Multicast communication is even
possible. A variety of scenarios are conceivable here depending on the network adapter, especially in the
case of Windows-based ad hoc wireless networks. You should also determine whether communication
with the NOXON is possible at the most basic level by pinging it.
Open the setup of the NOXON, select "Status" and scroll to the "IP Address" item. If "being configured" is
displayed here, then the device has not yet found a connection to the DHCP server, or a DHCP server is not
available. In this case, check your network configuration before proceeding.
Now, ping the NOXON from the computer running the music server. Open the command prompt (Start >
Run > and enter "CMD") and enter "ping 192.168.1.157", using the actual IP address of your NOXON, of
course. If you receive replies to your ping (the time in milliseconds until the reply was received will be dis-
played), then basic communication is possible. If that is not the case ("host unreachable"), then carefully
check your communication—especially with regard to encryption and IP addresses.
