      First, disable any commercial security software, ensuring to secure the network with a firewall of routers. Then, verify that all adapters are turned ON. Next, check that the LAN is properly wired between the adapter and the management computer, and that the power to the hub is ON. Finally, use a category five LAN cable up to 100m in length and connect the management computer and adapter to an Ethernet hub.
