Symptom Cause Solution
The LED is not lit. The WPN111 is not
connected to the

the WPN111
software is not
loaded.
Remove and reinsert the WPN111.

The wireless LED
blinks and cannot
connect to an
access point.
The WPN111 is
attempting to
connect to an access
point, but cannot
connect.
The access point may not be powered on. Or, the access point
and the WPN111 are not configured with the same wireless
parameters. Check the SSID and WEP settings.
I can connect to
an access point,
but I cannot
connect to other
computers on the
network or the
Internet.
This could be a
physical layer
problem or a network
configuration
problem.
Check to make sure that the access point is physically
connected to the Ethernet network.
Make sure that the IP addresses and the Windows networking
parameters are all configured correctly.
Restart the cable or DSL modem, router, access point, and
notebook PC.
