Troubleshooting

WEP Key (Network Key)

This is key information used for encrypting data

when conducting data transfer. On this unit, the

same WEP key is used for data encryption and

decryption, so the same WEP key must be set on

both devices in order for communications to be

established between them.

Wi-Fi

Wi-Fi Certiﬁcation assures tested and proven

interoperability by the Wi-Fi Alliance, a group

certifying interoperability among wireless LAN

devices.

Windows Media DRM

This is a copyright protection technology developed

by Microsoft.

Content providers are using the digital rights

management technology for Windows Media

contained in this device (WM-DRM) to protect

the integrity of their content (Secure Content) so

that their intellectual property, including copyright,

in such content is not misappropriated. This

device uses WM-DRM software to play Secure

Content (WM-DRM Software). If the security of

the WM-DRM Software in this device has been

compromised, owners of Secure Content (Secure

Content Owners) may request that Microsoft

revoke the WM-DRM Software’s right to acquire

new licenses to copy, display and/or play Secure

Content. Revocation does not alter the WM-DRM

Software’s ability to play unprotected content.

A list of revoked WM-DRM Software is sent to

your device whenever you download a license for

Secure Content from the Internet or from a PC.

Microsoft may, in conjunction with such license,

also download revocation list onto your device on

behalf of Secure Content Owners.

Windows Media Player Ver. 11 or later

This is a media player distributed free of charge by

Microsoft Corporation.

It can be used to play playlists created with

Windows Media Player Ver. 11 or later as well as

ﬁles in such formats as WMA, DRM WMA, MP3

and WAV.

WMA (Windows Media Audio)

This is audio compression technology developed by

Microsoft Corporation.

WMA data can be encoded using Windows Media

Player Ver.7, 7.1, Windows Media

Player

for Windows

XP and Windows Media

Player 9

Series.

To encode WMA ﬁles, only use applications

authorized by Microsoft Corporation. If you use

an unauthorized application, the ﬁle may not work

properly.

WPA (Wi-Fi Protected Access)

This is a security standard established by the Wi-Fi

Alliance. In addition to the conventional SSID

(network name) and WEP key (network key), it also

uses a user identiﬁcation function and encrypting

protocol for stronger security.

WPA2 (Wi-Fi Protected Access 2)

This is a new version of the WPA established by the

Wi-Fi Alliance, compatible with more secure AES

encryption.

WPA-PSK/WPA2-PSK (Pre-shared Key)

This is a simple authentication system for mutual

authentication when a preset character string

matches on the wireless LAN access point and

client.

WPS (Wi-Fi Protected Setup)

This is a standard drawn up by the Wi-Fi Alliance

to ease the task of setting up wireless LAN

connections and conﬁguring security.

There are two methods: push-button and PIN

(Personal Identiﬁcation Number) code.
