following table.
Problem
Possible Cause
Possible Solution
Unavailable
network
connection
Incorrect network
name (SSID) or
network key
Ad hoc connection:
verify that the network names (SSID’s) and network
keys (WEP) of all computers to be connected have been configured
correctly. SSID’s and WEP key values must be identical on each machine.
Access Point (Infrastructure) connection:
set the network name (SSID)
and network key to the same values as those of the access point.
Set the Network Authentication value identically to that of the Access
Point. Please consult your network administrator for this value, if
necessary.
For the method of setting network authentication, refer to the section of
this chapter related to the configuration tool or utility you are using.·

other wireless
networks
The use of identical or overlapping RF channels can cause interference
with the operation of the WLAN device. Change the channel of your
Access Point to a channel that does not overlap with the interfering
device.
Wireless network
authentication has
failed
Re-check your Network Authentication, Encryption, and Security
settings. Incorrectly configured security settings such as an incorrectly
typed WEP key, a mis-configured LEAP username, or an incorrectly
chosen authentication method will cause the LAN device to associate
but not authenticate to the wireless network.
Incorrectly
configured network
settings
Recheck the configuration of your network settings.
For the method of checking, refer to the following page:·“Connection to
the Network” on page 99.
Incorrect IP address
configuration
This only applies to networks using static IP addresses. Please contact
your network administrator for the correct settings.
