does not come on. 1. Make sure that you have loaded the network
device drivers.
2. Check all connections at the Ethernet controller
or adapter and the hub.

Removing Adapters” on page 61).
5. Use another port on the hub.
6. Make sure that the hub port is configured for
the correct speed (10 Mbps or 100 Mbps).
7. If you forced the duplex mode, make sure that
you also force the speed to either 10 Mbps or
100 Mbps.
8. If you manually configured the duplex mode,
make sure that you also manually configured
the speed.
If the problem still exists, have the system serviced.
