Cannot connect to the machine (the machine is not
detected)
Problem Possible Cause and Measures
The machine is not
detected
z
Confirm that the machine is turned on.
z
Move the machine closer to the access point or remove any obstacles.
z Firewall features provided by security software may prevent proper
setup or communication over a network. When setting up the machine
for use over a network, disable any firewall provided by security software
during the setup. For details on firewalls, see
“On Firewalls” on page 20 .
If you are using Windows XP Service Pack 1 or earlier and you have
Internet Connection Firewall enabled, a dialog box asking you for
confirmation to disable the firewall will appear during setup. Click [Yes] to
disable the firewall. When setup is complete, the firewall will be re-
enabled automatically.
To confirm the version of your Windows XP, see
“Confirming the version
of Windows XP” on page 71 .
z
If the access point is configured to use access control, register the IP
address or the MAC address of the machine or disable the access
control.
z
Confirm the network name/SSID of the target access point and set the
machine to use the identical network name/SSID. If the network name/
SSID is different in the machine and the access point, the machine
cannot connect to the access point. For details, see
“The [Access Points]
dialog box is displayed during setup” on page 61 .
z
Make sure that the machine and the access point can communicate with
each other under this setting. When encryption is set to the access point,
set up the encryption of the machine to match the settings of the access
point. If the WEP/WPA (encryption key) is different in the machine and
the access point, the machine cannot communicate with the access
point. For details, see
“How to set a WEP/WPA key” on page 59 .
z
The wireless channel to be used may be limited depending on wireless
network devices installed in the computer. Confirm the wireless channels
available for the network device. For details, refer to the manual
provided with your computer or your wireless network device.
Make sure that the channel set to the access point is valid to
communicate with the computer, confirmed above. If not, change the
channel set to the access point.
z
Some access points are capable of automatically switching between
wireless channels. This machine may not be able to connect an access
point if its channel is set to automatic or the equivalent, or to a channel
outside of the range 1 to 11. Configure the access point to use any
channel between 1 and 11.
