Common Ethernet Problems—Connectivity with Attached
Problem No link light.
Solution You might have used the wrong cable. Use a crossover cable
between the gateway and a host, and a straight-through cable between a
gateway and a hub.
Problem Steady activity LED.
Solution You might have set the wrong speed. Verify that the speeds match
on each end of the Ethernet connection (10 Mbps, 100 Mbps, or 1000 Mbps).
Problem Port not enabled.
Solution Verify from the Interface page in Nokia VPN Manager that the
interface port is configured as active.
Problem High collision rate on the hub.
Solution Disconnect connections one at a time until the problem is
localized to one computer and troubleshoot further.
