If the Hub doesn't connect to the network
1. Check the Link/Activity LED on the Hub. If the Link/Activity LED isn't lit, check all connections at the adapter and the Hub. Make sure the adapter drivers are loaded.
2. Try another port on the Hub.
3. Make sure the cable is installed properly. The network cable must be securely attached at all connections. If the cable is attached but the problem persists, try a different cable.
4. Turn off the power. After a while, turn on power again.
