Possible Solution
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 following
pages:· Windows XP: "Assigning parameters" on page 99·
Windows 2000: "Assigning parameters" on page 105
Ad hoc connection: Retry connection after shortening the distance to
the destination computer or removing any obstacles for better sight.
Access Point (Infrastructure) connection: Retry connection after short-
ening the distance to the access point or removing any obstacles for
better sight.
To check the wave condition, refer to the following pages:· Windows
XP: "Confirming the status of the radio waves" on page 103.· Windows
2000: "Confirming the status of the radio waves" on page 108
Check if the wireless switch is turned ON. Also verify "Disable Radio" is
not checked in "Network setting" window. Refer to "Starting Transmis-
sion" on page 98.
Check if the computer to be connected is turned ON.
If there is any other wireless LAN network nearby, change channels to
avoid active channel duplication. For the method of checking active
channels, refer to the following pages:· Windows XP: "Confirming the
status of the radio waves" on page 103· Windows 2000: "Confirming
the status of the radio waves" on page 108
Check if you have a right of access to the network to be connected with.
Check the protocol, work group name or shared setting.
For the method of checking, refer to the following pages:· Windows XP:
"Connection to the Network" on page 101· Windows 2000: "Connec-
tion to the Network" on page 106
If the setting of [Network authentication (shared mode)] is not matched
with that of access point or computer to be connected with, no commu-
nication can be established. Check the parameter setting.Refer to
"Assigning parameters" on page 99.
