WEP Key (Network Key)

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.

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)

authentication when a preset character string
matches on the wireless LAN access point and
client.
