Symptom After the WLSE starts up, the setup login prompt appears. Use the setup
program. The WLSE cannot connect to the network.
Possible Cause
–
The network cable is not connected to the Ethernet 0 port.
–
The Ethernet 0 interface is disabled or misconfigured.
–
The system is configured correctly, but the network is down or
misconfigured.
–
DNS is misconfigured. Ping commands will result in a 50-70% failure
rate in Pings from the WLSE (Web interface and CLI).
Recommended Action
1. Verify that the network cable is connected to the Ethernet 0 port and the
Ethernet indicator is lit.
–
If the network cable is not connected, connect it.
–
If the network cable is connected but the Ethernet indicator is not lit,
these are the probable causes:
The network cable is faulty.
The network cable is the wrong type (for example, a cross-over type,
rather than the required straight-through type).
The port on the default gateway to which the system connects is down.
–
If the network cable is connected and the Ethernet indicator is on but the
system cannot connect to the network, continue to the next step.
2. Use the ping command to perform the following tests:
–
Try to ping a well-known host on the network. A DNS server is a good
target host.
