Usability issues manifest themselves as taking extremely long amounts of time to discover fixtures and react to any user input (such as attempting to browse content on a fixture). The CMA program will also frequently go into a state of "Not Responding". These usability issues are caused by having multiple Network Interface Cards (NICs) active at the same time. As an example, a laptop that is connected to a DL.3/Axon network with wired Ethernet while at the same time being connected to a wireless network.
To resolve the issue, disable all NICs other than the one being used to connect to the DL.3/Axon network.
