1. Verify that an Ethernet cable is connected between the matrix and the network.

2. Type the IP address of the matrix into a web browser, as shown in the example below.
     Note: Computer must be on the same network as the matrix to access through IP.

Once set up is done and the webGUI is no longer being used, the firewall and anti-virus can be re-enabled. For assistance refer to KB01141 - Unable to access web interface of an Atlona device, however, pinging the unit does work.
