Troubleshooting
Wireless network
Symptom
The unit will not connect
to a wireless network.
You are positioned within a
wireless network and it is
available, but the icon of
the Connection Manager
indicates no signal
strength.
Cause or corrective action
 WIRELESS LAN switch is set to OFF.
 Reconnect to a wireless network manually (  page
148).
 Check if extra settings are required to connect to the
wireless network, such as security keys (WEP/WPA),
fixed IP address, or proxy setting (  page 149).
 The access point you want to use is set to make its SSID
invisible to users. In this case, the access point may not
be shown on the wireless network access point list. Clear
the invisible setting on the access point or put a
checkmark on "Hidden" (  page 149).
 The access point of the wireless network may be using a
security protection system not supported by this unit.
Consult with the administrator of your network.
 Some wireless network may require the MAC Address
of the unit to be registered with the network before the
unit is allowed to connect. The unit's MAC Address is
available by viewing the "System Information" on the
Tools menu. Connect again after the MAC Address has
been authorized for use on the wireless network.
 If the network settings of your network equipment are
not correct, adjust the settings as described in the
manuals that came with the networking equipment and
in any information provided by the administrator of
your network (  page 149).
 "Power Saving Mode" is activated. Deactivate "Power
Saving Mode" so that the unit stops limiting the power
for the network connection (  page 152).
 The unit is too far from the wireless hotspot. Move the
unit closer to the wireless hotspot.
 Obstacles such as walls metal, or concrete between the
unit and wireless network may adversely affect the
connection. Try moving the unit to a different location.
 If there is other equipment nearby using the 2.4 GHz
frequency band (such as a cordless phone, a microwave
oven, or Bluetooth computer equipment), move the
equipment away or turn it off.
 The network service is temporarily not available or
degraded. Check with the administrator of your
network for the status.
 Tap "Scan" of the "Connection Manager" screen. The
network status is renewed at the time either when the
"Connection Manager" screen is started or "Scan" is
tapped.
