Chapter 19 ‒ Network and ShowLink Troubleshooting
The most typical network problems are related to one or more devices not being discovered, or ‘seen’, on the network
by other devices. One indication that this problem exists is the lack of the network icon on the receiver LCD display.
It’s important to note, that when the network icon is displayed, it is simply an indication that two Axient products can
‘see’ each other on the network, it does NOT indicate other network problems. There are cases where you can have 10
receivers on the network and they all have network icons on the LCD displays, but there are still two or more that could
not be ‘seen’ by the remaining receivers.
For example, this case could happen if eight receivers had proper IP addresses from the DHCP server (192.168.1.x
addresses), but the remaining two receivers were connected to each other but not to the rest of the network. In this case,
the other two receivers will fall back to a private 169.254.x.x address and therefore ‘see’ each other, which will cause their
network icons to be on. To overcome the limitation of the network icon, we have included a new network tool in the Axient
products called ‘FIND ALL’. We’ll discuss this tool and its use in more detail in the following steps.
We’ll start with an example network topology that does not have a computer connected but does have a DCHP address
server on the network. We’ll cover the topologies with a computer connected in the chapter on Wireless Workbench
troubleshooting.
