Troubleshooting
Wireless LAN
Symptom
The player will not
connect to a wireless
network.
Cause/Remedy
 "WLAN Function On/Off " option is set to "Off. "
 Set the option to "On" (  page 127).
 Reconnect to a wireless network manually (  page 133).
 Check if extra settings are required to connect to the wireless
network, such as encryption key (WEP/WPA), fixed IP
address, or proxy setting (  page 127).
 The access point uses 152-bit encryption key or Shared Key
authentication as the encryption method.
 WEP of the player does not support 152-bit encryption key
nor Shared Key authentication.
 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. Enter the SSID manually
(  page 130).
 When connecting to the Internet, some public wireless LAN
access points require entering user ID and password by using
the Internet browser.
 Check the public wireless LAN service you intend to
connect to.
 The access point of the wireless network may be using a
security protection system not supported by the player.
 Consult with the administrator of your network.
 The access point may filter access by MAC address.
 Check the MAC address of the player (  page 137), then
register the MAC address with the access point to connect
to the wireless LAN.
 The network settings of the access point are not correct.
 Adjust the settings as described in the manuals that came
with the access point and in any information provided by
the administrator of the wireless LAN.
 The player is too far from the access point.
 Move the player closer to the access point.
 Obstacles such as walls metal, or concrete between the player
and access point may adversely affect the connection.
 Try moving the player to a different location.
 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 wireless LAN service is temporarily not available or
degraded.
 Check with the administrator of your wireless LAN service
for the status.
